Explanation

Abu l-Fazl was the son of Sheikh Mubarak Nagori, a distinguished scholar and Sufi saint who resided in Agra during the Mughal period. Sheikh Mubarak was a man of immense learning, well-versed in various branches of Islamic sciences and philosophy, and he provided a rigorous intellectual environment for his sons, Abu l-Fazl and Faizi. His liberal religious views and academic guidance were foundational in shaping Abu l-Fazl's own philosophical outlook, which eventually influenced the administrative and religious policies of Emperor Akbar. Sheikh Mubarak also played a critical role in drafting the Mahzar of 1579, a decree that established the Emperor's authority as the final arbiter in religious disputes.

Explanation

The French Revolution began in 1789, a year marked by the collapse of the absolute monarchy in France and the rise of democratic ideals. The process was initiated by the convening of the Estates-General in May to address the national debt, which led to the Third Estate declaring itself the National Assembly. A pivotal moment occurred on July 14, 1789, when Parisian citizens stormed the Bastille, an event that signified the end of the old order and the start of a decade of radical political and social change across the nation.

Explanation

Vande Mataram was composed by Bankim Chandra Chattopadhyay in the 1870s and was later included in his seminal Bengali novel Anandmath, published in 1882. The novel is set against the backdrop of the Sanyasi Rebellion and the devastating Bengal famine of 1770. In the narrative, the song is sung by the Sanyasi warriors as a hymn to the Motherland, personifying India as a mother goddess. It served as a powerful source of inspiration for the Indian independence movement and was first sung in a political context by Rabindranath Tagore at the 1896 session of the Indian National Congress. The song's inclusion in Anandmath established it as a central anthem of Indian nationalism.

Explanation

The Zika virus is primarily transmitted to humans through the bite of an infected mosquito from the Aedes genus, specifically Aedes aegypti and Aedes albopictus. These mosquitoes are typically active during the daytime, with peak biting activity occurring in the early morning and late afternoon. They are well-adapted to urban environments and frequently breed in small collections of stagnant water found in household items like flower pots, buckets, and discarded containers. The Aedes genus is a prolific vector for several arboviruses, as it also serves as the primary carrier for the dengue, chikungunya, and yellow fever viruses. Transmission occurs when a female mosquito ingests the virus while feeding on the blood of an infected person, after which the virus replicates in the mosquito and can be injected into a new host during subsequent feedings.

Explanation

Iceland is situated on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, which makes it one of the most volcanically and geologically active regions in the world. This unique positioning provides an abundant and easily accessible supply of geothermal energy. Iceland utilizes this resource more comprehensively than any other nation relative to its energy needs. Geothermal energy accounts for approximately nine out of ten households' heating requirements and generates a significant portion of the country's total electricity. Beyond power generation and space heating, the country utilizes geothermal resources for diverse applications such as heating greenhouses, fish farming, and industrial processes, representing a highly integrated and efficient model of energy utilization.

Explanation

In the root apical meristem of many plants, particularly monocotyledons, the root cap is produced by a specialized layer of meristematic tissue called the calyptrogen. This tissue is located at the distal end of the root apex and functions specifically to generate the cells of the root cap through active cell division. As the root grows through the soil, the outer cells of the root cap are continuously worn away or sloughed off, and the calyptrogen provides a constant supply of new cells to maintain the integrity and protective function of the root cap, also known as the calyptra.

Explanation

Western blotting, also known as protein immunoblotting, is the specific analytical technique used to detect and identify proteins in a given sample of tissue homogenate or extract. The process involves separating proteins based on their molecular weight or 3D structure through gel electrophoresis, typically using SDS-PAGE. Following separation, the proteins are transferred to a solid support membrane, such as nitrocellulose or polyvinylidene difluoride (PVDF). The identification is then achieved through the use of specific antibodies that bind to the target protein, which are subsequently detected using radiolabeled, fluorescent, or enzyme-linked secondary antibodies to visualize the protein's presence and quantify its relative abundance.

Explanation

During metaphase, chromosomes reach their maximum level of condensation and thickening, making them clearly visible under a light microscope. At this stage, each chromosome is distinctly composed of two sister chromatids joined at the centromere. The chromosomes align themselves along the equatorial plate of the cell, which allows for the most accurate observation of their size, shape, and numerical count. Because the morphological features are most well-defined and individual chromosomes are easiest to distinguish during this phase, metaphase is the standard stage used for karyotyping and identifying chromosomal abnormalities.

Explanation

A choke is an inductor consisting of a coil of insulated copper wire wound over a laminated soft iron core. In a fluorescent tube light circuit, it performs two essential functions. Initially, it works in conjunction with the starter to produce a high-voltage surge through the principle of self-induction, which is necessary to ionize the gas inside the tube and initiate the electrical discharge. Once the tube is lit, the inductive reactance of the choke acts as a ballast to limit and stabilize the current flowing through the gas. This is necessary because the gas discharge has a negative resistance characteristic, meaning the current would otherwise increase indefinitely and destroy the tube. Using an inductor for this purpose is efficient because it limits current through reactance rather than resistance, thereby minimizing energy loss as heat.

Explanation

The Curie (symbol Ci) is a unit of radioactivity defined as the quantity of any radioactive nuclide in which the number of disintegrations per second is 3.7 × 10¹⁰. It was originally based on the activity of one gram of radium-226 (²²⁶Ra), the element discovered by Marie and Pierre Curie, in whose honor the unit is named. In the International System of Units (SI), radioactivity is measured in Becquerels (Bq), where one Becquerel equals one disintegration per second. Therefore, one Curie is exactly equal to 3.7 × 10¹⁰ Becquerels. It serves as a measure of the rate at which a radioactive material emits radiation through nuclear decay.

Explanation

WEP stands for Wired Equivalent Privacy. It was the inaugural security protocol introduced in 1997 as part of the original IEEE 802.11 standard for wireless networking. The primary goal of WEP was to provide a level of data confidentiality for wireless communication that is equivalent to that of a traditional wired local area network. It utilizes the RC4 stream cipher for encryption and a CRC-32 checksum for data integrity to protect wireless traffic from unauthorized eavesdropping. The name reflects the design objective of making the radio-based transmission link as secure as a physical cable by ensuring that data packets are encrypted before they are broadcast over the air.

Explanation

Carbon dioxide (CO₂) is an effective fire suppressant because it is non-combustible and heavier than air. When discharged from an extinguisher, it creates a dense blanket over the fuel, displacing the oxygen required to sustain the chemical reaction of combustion. By effectively cutting off the oxygen supply, it suffocates the flames. Additionally, CO₂ is stored under high pressure as a liquid; when it is released, the rapid expansion causes a significant drop in temperature, which can help cool the burning material. It is a preferred agent for electrical fires because it does not conduct electricity and for fires involving sensitive equipment because it leaves behind no solid residue or moisture.

Explanation

The Western Ghats, also known as the Sahyadri, comprise a continuous range of mountains that runs for approximately 1,600 km parallel to the western coast of the Indian peninsula. They rise abruptly from the narrow western coastal plains as a result of the faulting and subsidence of the Arabian Sea basin during the Gondwana breakup. Because of their continuous nature, they can only be crossed through specific passes such as the Thalghat, Bhorghat, and Palghat. This range forms the western edge of the Deccan Plateau and serves as a major watershed for many of the large peninsular rivers.

Explanation

India possesses the world's largest known reserves of thorium, which are primarily found in the monazite sands along its extensive coastline. Estimates from the International Atomic Energy Agency and the Department of Atomic Energy indicate that India holds approximately 25 percent of the global thorium deposits. These concentrated deposits are located in the beach sands of Kerala, Tamil Nadu, Andhra Pradesh, and Odisha. Thorium is the cornerstone of India's three-stage nuclear power programme, designed by Homi J. Bhabha to leverage these vast resources for long-term energy security through the use of thorium-based reactors and Advanced Heavy Water Reactors.

Explanation

The Netherlands became the first country in the world to formally legalize euthanasia and assisted suicide. The Dutch Parliament passed the Termination of Life on Request and Assisted Suicide (Review Procedures) Act in April 2001, and the law officially went into effect on April 1, 2002. This landmark legislation established a legal framework and strict medical criteria under which physicians can end a patient's life or provide the means for suicide at the patient's explicit request, provided the patient is experiencing unbearable suffering with no hope of recovery and the request is made voluntarily and with full awareness.

Explanation

Portugal claimed their first major international trophy by winning the 2016 UEFA European Championship. In the final match played at the Stade de France, the Portuguese side secured a 1-0 victory after extra time. The winning goal was scored in the 109th minute by the substitute striker Eder, who hit a low shot from outside the penalty area. This triumph was particularly significant as the team played a large portion of the final without their captain, Cristiano Ronaldo, who was forced off due to an injury early in the game. Under the tactical guidance of coach Fernando Santos, Portugal finished the tournament undefeated to become the European champions.

Explanation

Pandit Shivkumar Sharma was a legendary Indian classical musician who is globally credited with introducing the Santoor to the Hindustani classical music tradition. Originally a folk instrument used primarily in the Sufiana Mausiqi of the Kashmir valley, the Santoor was modified and refined by Sharma to suit the technical requirements of classical ragas. He innovated specific playing techniques, such as using the mallets to create the meend or glissando effect, which allowed the instrument to produce the continuous melodic lines essential to Indian music. His efforts transformed the hundred-stringed hammered dulcimer into a prestigious solo instrument recognized on international concert stages.

Explanation

Oscar Carl Pistorius is a South African former professional sprinter who earned the nickname Blade Runner due to the carbon-fiber prosthetic blades he used for competition. Having undergone double below-the-knee amputations as an infant, he competed in both Paralympic and non-disabled sprint events. He gained international fame for using the J-shaped Cheetah Flex-Foot prostheses, which resembled blades, allowing him to achieve elite speeds on the track. Pistorius became the first double-leg amputee to participate in the Olympic Games when he competed in the 400 meters and the 4x400 meters relay at the London 2012 Olympics. His moniker reflects both his unique athletic equipment and his status as a pioneer in para-athletics transitioning to mainstream international competition.

Explanation

The Foreign Contribution (Regulation) Act is a law enacted by the Parliament of India to regulate the acceptance and utilization of foreign contribution or foreign hospitality by individuals, associations, and companies. Administered by the Ministry of Home Affairs, the primary objective of this legislation is to ensure that foreign funding does not adversely affect the internal security or the sovereign and democratic framework of the country. Organizations or NGOs intended to receive foreign donations are required to register under this act and adhere to strict compliance norms, including the maintenance of separate accounts and the filing of annual returns regarding the receipt and utilization of such funds.

Explanation

Silver undergoes a chemical reaction known as tarnishing when it comes into contact with hydrogen sulphide (H₂S) gas present in the atmosphere. Although silver is a relatively unreactive noble metal, it has a high affinity for sulphur. When silver reacts with even trace amounts of hydrogen sulphide in the air, it forms a thin, black layer of silver sulphide (Ag₂S) on its surface. The chemical reaction is represented as 2Ag + H₂S → Ag₂S + H₂. This silver sulphide layer is responsible for the loss of luster and the characteristic blackening or corrosion observed on silver ornaments and utensils over time. While silver does not readily react with oxygen or moisture at room temperature, the presence of sulphur-containing compounds is the primary driver of its surface degradation.

Explanation

Uranium is a dense, metallic chemical element with the atomic number 92. It is inherently radioactive because its nucleus is unstable and lacks the binding energy to remain intact indefinitely. All naturally occurring isotopes of uranium, including Uranium-238 and Uranium-235, undergo spontaneous radioactive decay by emitting alpha particles. This decay process continues through a series of daughter isotopes until a stable isotope of lead is formed. Due to its ability to sustain a nuclear chain reaction through the process of nuclear fission, uranium is the primary fuel used in nuclear power plants and is the heaviest naturally occurring element found in significant quantities on Earth.

Explanation

The Right to Constitutional Remedies is a Fundamental Right guaranteed under Article 32 of the Constitution of India. Contained within Part III, which enumerates the fundamental rights of citizens, this provision empowers individuals to move the Supreme Court for the enforcement of their rights. Dr. B.R. Ambedkar described Article 32 as the soul of the Constitution and its very heart because it provides a judicial mechanism to protect and reinstate the fundamental liberties of citizens through the issuance of directions, orders, or writs such as Habeas Corpus, Mandamus, Prohibition, Quo Warranto, and Certiorari.

Explanation

The stomach contains gastric juice, which is primarily composed of hydrochloric acid (HCl). This acid is secreted by the parietal cells located within the gastric glands of the stomach's mucosal lining. The presence of hydrochloric acid creates a highly acidic environment, typically with a pH ranging from 1.5 to 3.5. This acidity is essential for the digestive process as it denatures proteins and activates the enzyme pepsinogen into its active form, pepsin, which begins the digestion of proteins. Furthermore, the acidic environment serves as a protective barrier by killing most of the bacteria and other microorganisms that enter the digestive tract along with food and liquids.

Explanation

Sri Lanka is an island nation located off the southeastern coast of the Indian peninsula. It is separated from the Indian mainland by a narrow stretch of sea comprising the Palk Strait and the Gulf of Mannar. The Palk Strait lies to the northeast of the chain of shoals known as Adam Bridge, connecting the Bay of Bengal with Palk Bay, while the Gulf of Mannar lies to the southwest. This maritime boundary between the Tamil Nadu state of India and the Mannar District of Sri Lanka serves as the primary geographical divider between the two nations.

Explanation

Silk is widely recognized as the strongest natural fibre found in nature. It is a protein fibre produced by certain insect larvae to form cocoons, with the most well-known variety being obtained from the silkworm Bombyx mori. The exceptional strength of silk is attributed to its chemical composition and internal structure, primarily consisting of the protein fibroin. The fibroin molecules are arranged in a series of closely packed, antiparallel beta-pleated sheets held together by hydrogen bonds. This highly ordered crystalline structure allows the fibre to withstand significant tensile stress without breaking. On a weight-for-weight basis, silk possesses a tensile strength that is comparable to high-grade steel and superior to most other natural fibres derived from plants or animals.

Explanation

An optical filter is a device designed to selectively transmit light of specific wavelengths or colors while absorbing or blocking the remaining part of the spectrum. The functionality depends on the chemical or physical properties of the filter material, which allow it to act as a wavelength-selective barrier. When polychromatic light passes through the filter, the energy of unwanted frequencies is absorbed by the material, while the desired wavelengths are allowed to pass through relatively unobstructed. This process is essential in fields such as photography, astronomy, and spectroscopy to control the spectral composition of light reaching a sensor or observer.

Explanation

Excess-3 code is a non-weighted code because its bit positions do not carry specific mathematical weights. In a weighted code, each bit position has a fixed value, and the decimal equivalent is found by summing the products of the bits and their weights. Excess-3 is instead derived by adding 3 (binary 0011) to the 8421 BCD representation of a decimal digit. Because of this constant offset, there is no set of weights w₃, w₂, w₁, w₀ that can be assigned to the bit positions to represent the decimal digits correctly through summation. This characteristic classifies it as a non-weighted code, which is primarily utilized in digital systems for its self-complementing property during arithmetic operations.

Explanation

The RESIDEX is India's first official housing price index, launched in 2007 by the National Housing Bank (NHB). It tracks the movement in prices of residential real estate, which fundamentally involves land and built-up property, across major Indian cities. The index provides a standardized tool to monitor price trends in the property market, helping stakeholders such as home seekers, banks, and developers understand fluctuations and value changes in the land and housing sector.

Explanation

The ozone layer, located primarily in the Earth's stratosphere between 15 and 35 kilometers above the surface, acts as a protective shield for the biosphere by absorbing the majority of the Sun's high-energy ultraviolet (UV) radiation. Specifically, it filters out nearly all of the highly lethal UV-C radiation and about 95% of harmful UV-B radiation. These ultraviolet rays possess enough energy to break chemical bonds and cause significant biological damage, including DNA mutations, skin cancers, cataracts, and the suppression of the human immune system. The absorption occurs via the ozone-oxygen cycle, where ozone (O₃) molecules absorb UV photons and dissociate into an oxygen molecule (O₂) and a free oxygen atom (O), effectively converting high-energy radiation into heat before it reaches the Earth's surface.

Explanation

Pandit Birju Maharaj was a legendary maestro and the preeminent exponent of Kathak, a classical dance form originating from Northern India. He belonged to the Kalka-Bindadin gharana of Lucknow, a lineage renowned for its mastery of rhythm and expressive storytelling. As a descendant of a family of Kathak dancers that included his father Acchan Maharaj and uncles Shambhu Maharaj and Lachhu Maharaj, he played a crucial role in modernizing and popularizing the dance form on international stages. His artistry was characterized by intricate footwork, graceful movements, and subtle abhinaya (expression). In recognition of his immense contributions to Indian classical arts, he was honored with the Padma Vibhushan in 1986, along with numerous other prestigious awards.

Explanation

Annie Besant was elected as the president of the Indian National Congress during its 32nd annual session held in Calcutta in December 1917. An Irish-British activist and a key leader of the Home Rule movement, her election marked the first time a woman held the presidency of the Congress. This appointment was a significant moment in the Indian nationalist struggle, reflecting the broadening base of the party's leadership and the growing involvement of women in the political sphere during the early 20th century.

Explanation

Rashtriya Mahila Kosh (RMK), established in 1993 as the National Credit Fund for Women, is an autonomous body under the Ministry of Women and Child Development. It functions as an apex micro-finance organization specifically designed to meet the credit needs of poor and assetless women in the informal sector. The programme provides micro-loans for various livelihood and income-generating activities by routing funds through Intermediary Organizations such as NGOs, Self-Help Groups, and Women's Development Corporations. RMK emphasizes easy, collateral-free access to credit to help women achieve economic self-reliance and empowerment.

Explanation

Under Article 151(1) of the Constitution of India, the Comptroller and Auditor-General (CAG) of India is required to submit the audit reports relating to the accounts of the Union to the President. The President then causes these reports to be laid before each House of Parliament. This constitutional provision ensures that the legislature is informed about the financial conduct of the executive. The CAG acts as an independent authority that scrutinizes the legality and propriety of government expenditure, and the submission of these reports to the President is a critical step in the process of parliamentary oversight of public finances.

Explanation

The first Buddhist Council was convened in 483 BCE at the Sattapanni Cave in Rajagriha, shortly after the Mahaparinirvana of Gautama Buddha. It was held under the royal patronage of King Ajatashatru of the Haryanka dynasty and presided over by the elder monk Mahakasyapa. The primary objective of the council was to preserve the Buddha's teachings (Sutta) and the rules of monastic discipline (Vinaya). During this assembly, the Buddha's closest disciples, Ananda and Upali, recited the Sutta Pitaka and Vinaya Pitaka, respectively, ensuring the authentic oral transmission of the Buddhist canon to future generations.

Explanation

The Nilgiri Hills, also known as the Blue Mountains, constitute the physical junction where the Western Ghats and the Eastern Ghats meet. This mountain range forms a high-altitude plateau at the tri-junction of the Indian states of Tamil Nadu, Karnataka, and Kerala. While the Western Ghats run continuously along the western coast and the Eastern Ghats are a series of discontinuous hills along the eastern coast, they converge at this point to form a mountain knot. The highest peak in the Nilgiri Hills is Doddabetta, which reaches an elevation of 2,637 meters. This region is a significant part of the Nilgiri Biosphere Reserve, representing a transition zone between the two major mountain systems of Peninsular India.

Explanation

Simuka is historically recognized as the founder of the Satavahana dynasty, which rose to power in the Deccan region after the decline of the Mauryan Empire and the subsequent Kanva dynasty. Mentioned in various Puranic lists as the first king of the Andhra-Satavahana line, he established his rule around the late 1st century BCE. He is credited with consolidating territories in the Godavari and Krishna river basins into a centralized kingdom, laying the foundation for a dynasty that would dominate central and southern India for several centuries. Early Satavahana inscriptions and archaeological evidence, including those found at Naneghat, corroborate his position as the inaugural ruler who initiated the political ascent of the empire.

Explanation

The Indian National Congress underwent its first major split during the Surat session in 1907, an event historically referred to as the Surat Split. This division was the result of growing ideological friction between two groups: the Moderates and the Extremists. The Moderates favored constitutional methods, petitions, and gradual reforms within the framework of British law. In contrast, the Extremists advocated for more radical approaches, including the Boycott and Swadeshi movements, and sought a more aggressive stance against British rule. The confrontation escalated over the choice of the session president and the specific wording of resolutions on national education and self-government. Rash Behari Ghosh presided over this session, which ended in chaos and the formal expulsion of the Extremist faction from the party.

Explanation

Silica gel is a highly porous, granular form of silicon dioxide (SiO₂) that acts as a powerful desiccant. It functions through the process of physical adsorption, where water molecules are attracted to and trapped within its vast network of microscopic pores. Due to its exceptionally high surface area and strong affinity for water vapor, it is used to maintain low humidity in enclosed environments. This makes it an essential drying agent for protecting moisture-sensitive products such as electronics, pharmaceuticals, and leather goods from damage caused by condensation, mold, or corrosion.

Explanation

The Purushottam Express, which runs between Puri and New Delhi, became the first train in India to be equipped with Braille-integrated signages and signals in its coaches. This initiative by the Indian Railways was designed to assist visually impaired passengers in navigating the train independently. The AC coaches were fitted with Braille stickers on berth numbers, toilet doors, washbasins, and emergency exit routes. These metal-based Braille signages were developed to be durable and user-friendly, marking a significant step toward making the rail network more accessible for specially-abled commuters.

Explanation

Biofertilizers contain living microorganisms such as Rhizobium, Azotobacter, and Azospirillum which facilitate the process of biological nitrogen fixation. These microbes possess a specialized enzyme complex called nitrogenase that breaks the strong triple bond of atmospheric dinitrogen (N₂). Through a series of reduction reactions requiring energy in the form of ATP, the nitrogenase enzyme converts atmospheric nitrogen specifically into ammonia (NH₃). This ammonia serves as the first stable product of nitrogen fixation and is subsequently assimilated by the plant to synthesize proteins and other essential biomolecules. The overall chemical reaction is represented as N₂ + 8H⁺ + 8e⁻ + 16ATP → 2NH₃ + H₂ + 16ADP + 16Pᵢ.

Explanation

Shiva Thapa is a prominent Indian boxer from Assam who competes in the bantamweight and lightweight categories. He made history by becoming the youngest Indian boxer to qualify for the Olympics when he participated in the 2012 London Games at the age of 18. His major achievements prior to mid-2016 include winning a gold medal at the 2013 Asian Confederation Boxing Championships and a bronze medal at the 2015 World Amateur Boxing Championships held in Doha. He also secured a spot to represent India at the 2016 Rio Olympics.

Explanation

Kaziranga National Park, located in the Golaghat and Nagaon districts of Assam, serves as the most significant natural habitat for the Great One-horned Rhinoceros (Rhinoceros unicornis). Situated along the floodplains of the Brahmaputra River, the park consists of vast expanses of tall elephant grass, marshland, and dense tropical moist broadleaf forests, which provide the ideal grazing and wallowing conditions required by the species. As of 2016, Kaziranga hosts approximately two-thirds of the world's total population of these rhinoceroses. Due to its unique ecological importance and successful conservation efforts for this species, it was declared a UNESCO World Heritage Site in 1985.

Explanation

The United Kingdom held a national referendum on June 23, 2016, to decide whether it should remain a member of or leave the European Union. In the vote, commonly referred to as Brexit, approximately 51.9 percent of the participating voters chose to leave the union. This decision marked the first time a member state voted to withdraw from the European Union since its inception, leading to the invocation of Article 50 of the Treaty on European Union to begin the formal exit process.

Explanation

Capital goods are physical assets such as machinery, equipment, tools, and buildings that are utilized in the production process to create other goods and services. Unlike consumer goods, which are purchased for immediate satisfaction of human needs, capital goods are durable items that facilitate the manufacturing of final products over a long period. They are essential components of an economy's productive capacity, as they are used as inputs to generate future output and wealth rather than being consumed in a single use.

Explanation

According to Article 75 of the Indian Constitution, the Prime Minister is appointed by the President and other ministers are appointed by the President on the advice of the Prime Minister. Although Article 75(2) states that ministers hold office during the pleasure of the President, the President exercises this power only upon the recommendation of the Prime Minister. In the parliamentary system of government, the Prime Minister has the primary authority over the composition of the Council of Ministers. If the Prime Minister is dissatisfied with a minister's performance or if there is a difference of opinion, the Prime Minister can ask for the minister's resignation or advise the President to dismiss them.

Explanation

The Securities and Exchange Board of India (SEBI) is the statutory regulatory body established by the Government of India to oversee the Indian securities and capital markets. It was granted statutory powers on January 30, 1992, through the Securities and Exchange Board of India Act, 1992. SEBI is responsible for protecting the interests of investors in securities, promoting the development of the securities market, and regulating the activities of stock exchanges and other market intermediaries. It exercises regulatory control by formulating rules and regulations, conducting inspections, and ensuring the orderly functioning of the financial markets to prevent fraudulent and unfair trade practices.

Explanation

Dharampala, the second ruler of the Pala Dynasty, established Vikramshila University during the late 8th or early 9th century. Located in present-day Bhagalpur, Bihar, it was founded to serve as a premier center for Buddhist learning when the standards of scholarship at Nalanda were perceived to be declining. Under the patronage of the Pala kings, the university became a major seat of Vajrayana Buddhism and attracted students from across Asia, most notably producing the great scholar Atisa Dipankara who revived Buddhism in Tibet.

Explanation

Eucalyptus is the most widely utilized species in social forestry programs due to its exceptionally fast growth and ability to thrive in diverse ecological zones. Introduced on a large scale in India during the 1970s and 1980s, it satisfies the primary objectives of social forestry by providing a quick supply of fuel wood, poles for construction, and raw material for the pulp and paper industry. Its non-palatability to livestock ensures high survival rates without intensive fencing, making it an economically viable choice for plantation on farm boundaries, degraded lands, and strip lands along roads and canals.

Explanation

Estuaries are among the most productive ecosystems in the biosphere because they serve as nutrient traps, receiving a continuous supply of organic and inorganic nutrients from both land runoff via rivers and the sea via tidal action. This high nutrient availability, combined with shallow water that allows for maximum sunlight penetration, supports intense photosynthetic activity by various primary producers such as phytoplankton, algae, and salt marsh plants. The constant circulation of water by tides further enhances productivity by replenishing oxygen and distributing nutrients throughout the water column, resulting in a very high Net Primary Productivity per unit area.

Explanation

When a car moves around a curve, it is continuously changing its direction of motion, which constitutes centripetal acceleration. According to Newton's Second Law of Motion, any acceleration requires a net force acting in the direction of that acceleration. For an object in circular or curved motion, this force must be directed toward the center of the curvature and is defined as centripetal force. In the case of a vehicle, this force is provided by the friction between the tires and the road surface. The mathematical expression for this force is F_c = (mv²)/(r), where m represents the mass of the car, v is its tangential velocity, and r is the radius of the curve. Without this center-seeking force, the car would continue to travel in a straight line tangent to the curve due to its inertia.
