Explanation

Oneirology is the scientific study of dreams, focusing on the relationship between dreaming and brain function as well as the physiological mechanisms that produce dreams. Unlike dream interpretation, which seeks to assign symbolic meaning to dream content, oneirology quantitatively analyzes the mental processes and brain activity occurring during the dreaming state, particularly during Rapid Eye Movement (REM) sleep. The term is derived from the Greek word oneiron, meaning dream, and logia, meaning study. Researchers in this field utilize neuroimaging and electroencephalography (EEG) to investigate how dreams relate to memory consolidation, emotional processing, and neurological disorders.

Explanation

Article 368 of the Constitution of India, contained within Part XX, vests the Parliament with the constituent power to amend the Constitution by way of addition, variation, or repeal of any of its provisions. The article prescribes a specific procedure for such amendments, requiring a bill to be passed in each House of Parliament by a special majority—defined as a majority of the total membership of the House and a majority of not less than two-thirds of the members present and voting. In cases where the amendment seeks to change the federal character of the Constitution, such as the distribution of legislative powers between the Union and the States, it also requires ratification by the legislatures of at least half of the States. This power is subject to the judicial doctrine that the Parliament cannot use Article 368 to alter the basic structure of the Constitution.

Explanation

A flow channel is a component of an irrigation system where water is conveyed from a source to the fields entirely by the force of gravity. This system is viable when the water level at the source or within the canal is maintained at an elevation higher than the ground level of the area to be irrigated. The natural gradient of the land allows the water to move spontaneously through the canal network without the assistance of mechanical pumps or external energy sources. Such channels are the fundamental feature of flow irrigation, which is the most common method used in gravity-based canal projects across various topographical regions where a consistent downward slope can be maintained from the headworks to the agricultural plots.

Explanation

Keibul Lamjao National Park, located in the Bishnupur district of Manipur, is recognized as the only floating national park in the world. It is a vital part of Loktak Lake, which is the largest freshwater lake in Northeast India. The park's unique characteristic is the presence of phumdis, which are floating heterogeneous masses of vegetation, soil, and organic matter in various stages of decomposition. These phumdis are thick enough to support the weight of animals and humans. The park serves as the last natural habitat for the critically endangered Sangai, also known as the Brow-antlered deer or the dancing deer, which is the state animal of Manipur. The ecosystem is a rare combination of aquatic, wetland, and terrestrial features, making it a globally unique conservation area.

Explanation

Article 265 of the Constitution of India mandates that no tax shall be levied or collected except by authority of law. This provision ensures that the executive branch of the government cannot impose or collect any tax through mere administrative or executive orders. Any taxation must be backed by a valid piece of legislation enacted by the Parliament or a State Legislature that has the specific legal competence to do so. The term authority of law implies that the statute authorizing the tax must be validly enacted and must not contravene any fundamental rights or other constitutional provisions. This article serves as a crucial safeguard for citizens against arbitrary taxation and upholds the principle of the rule of law in the financial administration of the country.

Explanation

Remittances refer to the money or goods that migrants send back to their families or communities in their place of origin. These transfers represent a portion of the migrant's earnings and are a significant source of external resource flows for many developing countries. In the context of migration studies and economic geography, remittances are categorized as either internal or international, playing a vital role in the socio-economic development of the recipient households by supporting expenditures on food, education, healthcare, and debt repayment.

Explanation

Terrace farming is a specialized agricultural technique used on hilly or mountainous terrain where flat land is naturally scarce. By cutting a series of level steps or platforms into the steep slopes, farmers create arable plots that resemble a giant staircase. This structural modification is essential for managing water flow, as the flat terraces catch rainwater and prevent it from rushing down the slope. By slowing the velocity of runoff, terrace farming significantly reduces soil erosion and allows the ground to absorb moisture effectively, making it possible to cultivate crops like rice, tea, and vegetables on land that would otherwise be too steep for farming.

Explanation

The Government of India announced in January 2021 that the birth anniversary of Netaji Subhash Chandra Bose, celebrated on 23 January, would henceforth be commemorated as Parakram Diwas every year. This decision was taken to honor Netaji's indomitable spirit and selfless service to the nation, inspiring citizens, especially the youth, to act with fortitude in the face of adversity. Netaji was born on 23 January 1897 in Cuttack, Odisha, and played a pivotal role in India's independence movement through his leadership of the Azad Hind Fauj. The inaugural Parakram Diwas was observed in 2021 to mark his 125th birth anniversary.

Explanation

Dmitri Mendeleev is credited with the formulation of the Periodic Law in 1869, which states that the physical and chemical properties of elements are periodic functions of their atomic weights. By arranging the 63 elements known at the time in increasing order of their atomic weights, he noticed a recurring pattern of properties, leading to the creation of the first Periodic Table. His work was revolutionary because he left intentional gaps for undiscovered elements and accurately predicted their properties, such as those of gallium and germanium. This systematic arrangement transformed chemistry from a collection of isolated facts into a structured science based on the periodic recurrence of elemental characteristics.

Explanation

Harishena was the court poet and a high-ranking official, holding the title of Sandhivigrahika (Minister of War and Peace), in the administration of the Gupta emperor Samudragupta. He composed the famous Allahabad Prashasti, also known as the Prayag Prashasti, which is inscribed on an Ashokan pillar at Allahabad. This eulogy is written in elegant Sanskrit using the Champu style, which blends both prose and verse. The inscription provides a detailed historical account of Samudragupta's extensive military conquests, his diplomatic relations, and his personal virtues, making it one of the most important epigraphic sources for the Gupta period.

Explanation

Phosphine (PH₃) is a colorless, flammable gas that is naturally produced through the anaerobic degradation of organic matter containing phosphorus. This biochemical process occurs in environments devoid of oxygen, such as marshes, swamps, and sewage treatment plants, where specialized microorganisms reduce phosphate or organic phosphorus compounds. Small amounts of phosphine are often released alongside other gases during the decomposition of biological tissues. It is notably responsible for the ignis fatuus or will-o'-the-wisp effect, where the spontaneous combustion of impure phosphine in the presence of diphosphane creates flickering lights over wetlands.

Explanation

Dadabhai Naoroji, known as the Grand Old Man of India, authored the landmark book Poverty and Un-British Rule in India, which was published in 1901. In this work, Naoroji formulated and popularized the Drain of Wealth theory, providing a detailed economic critique of British colonial rule. He argued that the British administration was systematically siphoning off India's resources and wealth to Great Britain through various mechanisms, including home charges, pensions, and interest on public debt, without any equivalent economic return to India. By using the term un-British, Naoroji highlighted the contradiction between the democratic values upheld in Britain and the exploitative, autocratic nature of British rule in India. His statistical analysis of Indian poverty and the economic drain laid the intellectual foundation for the Indian nationalist movement and the demand for self-rule.

While established in 1957, the first set of awards was presented on August 31, 1958.

Explanation

Lymph is a component of the lymphatic system, consisting of interstitial fluid that enters lymphatic vessels. It contains a high concentration of lymphocytes, a specific type of white blood cell essential for the body's immune response. As lymph circulates, it is filtered through lymph nodes, which act as specialized trap stations. Within these nodes, the white blood cells identify, engulf, and destroy harmful bacteria and other foreign microorganisms that have invaded the body's tissues. This process prevents bacterial pathogens from spreading through the bloodstream, thereby protecting the body from various infections and diseases.

Explanation

Autotrophic organisms, such as green plants and some bacteria, fulfill their carbon and energy requirements through the process of photosynthesis. During this biochemical process, these organisms capture solar energy using pigments like chlorophyll and use it to convert inorganic carbon dioxide from the atmosphere and water from the soil into organic molecules like glucose. The carbon dioxide serves as the primary carbon source for synthesizing complex organic compounds, while the absorbed light energy is transformed into chemical energy stored within the bonds of these carbohydrates. This synthesized food provides the necessary fuel and building blocks for the organism's growth, development, and cellular functions.

Explanation

The umbilical cord serves as the physiological connection between the developing fetus and the placenta. In a typical human pregnancy, the umbilical cord contains three blood vessels: one umbilical vein and two umbilical arteries. These two umbilical arteries arise from the internal iliac arteries of the fetus and carry deoxygenated, nutrient-depleted blood along with metabolic waste products away from the fetus to the placenta. Once the blood reaches the placenta, it undergoes gas exchange and nutrient absorption from the maternal blood supply. The presence of two arteries alongside a single vein is the standard anatomical arrangement that ensures efficient waste removal and circulatory balance for the growing embryo.

It holds immense significance in Buddhism as the location where Gautama Buddha delivered his first sermon, known as the Dhammacakkappavattana Sutta or the Turning of the Wheel of Dharma, to his first five disciples after attaining enlightenment. The site features several major historical structures, including the Dhamek Stupa, which marks the spot of the first sermon, and the Chaukhandi Stupa. It is also the location where the Lion Capital of Ashoka was found, which is now the National Emblem of India. Sarnath remains one of the four primary pilgrimage sites for Buddhists worldwide.

Explanation

Sea waves are a product of exogenic forces, which are external processes that originate on or above the Earth's surface. They are primarily generated by the kinetic energy of wind blowing over the surface of the ocean, a process driven by atmospheric pressure differences and solar energy. In geomorphology, sea waves function as agents of denudation, responsible for the erosion, transportation, and deposition of sediments along coastlines. Because their energy source is derived from the atmosphere and the sun rather than from the Earth's internal heat or tectonic movements, they are not categorized as outcomes of internal geological processes.

Explanation

Article 123 of the Indian Constitution empowers the President to promulgate ordinances during the recess of Parliament. This legislative power is used when either of the two Houses of Parliament is not in session and the President is satisfied that circumstances exist which render it necessary to take immediate action. An ordinance issued under this Article has the same force and effect as an Act of Parliament. To remain in force, the ordinance must be laid before both Houses of Parliament and approved within six weeks from the date of reassembly, otherwise it ceases to operate. This provision ensures that the executive can respond to urgent situations when the legislature is unable to meet.

Explanation

It eventually joins the Brahmaputra River in Bangladesh, making it a vital right-bank tributary of the Brahmaputra river system. The river is also notable for hosting several major hydroelectric projects in Bhutan, such as the Chukha and Tala plants.

Explanation

The term Hindu Rate of Growth was coined by the Indian economist Raj Krishna in 1978 during a lecture at the Federation of Indian Chambers of Commerce and Industry. He used this expression to describe the low annual growth rate of the Indian economy, which stagnated at around 3.5 percent between the 1950s and the 1980s. This sluggish performance was attributed to the restrictive economic policies of the license raj and inward-looking socialist planning. The terminology captured the persistent and stable nature of this low growth trajectory, suggesting a sense of fatalism before the country moved toward major economic liberalization and higher growth paths in the subsequent decades.

Explanation

Sri Harmandir Sahib, popularly known as the Golden Temple, is the most sacred pilgrimage site of Sikhism and is located in the city of Amritsar. The holy tank (sarovar) around which the temple is built was excavated by Guru Ram Das, the fourth Sikh Guru, while the temple itself was designed and constructed by Guru Arjan Dev, the fifth Sikh Guru. To symbolize the universal nature of the faith, Guru Arjan Dev invited the Sufi saint Mian Mir of Lahore to lay the foundation stone in 1589. The temple features four doors opening in all four directions, signifying that people from all religions and backgrounds are welcome. The iconic gold gilding of the structure was completed in 1830 under the patronage of Maharaja Ranjit Singh.

Explanation

The resolution sought the inclusion of a distinct Sarna Code in the Census of 2021, addressing a long-standing demand of the tribal population in the state. Tribal groups in Jharkhand follow the Sarna faith, which is based on nature worship and is distinct from other organized religions. By passing this resolution, the state government aimed to provide a separate identity to these communities in official demographic records.

Explanation

The velocity of a wave is defined as the distance traveled by the wave per unit of time. For a periodic wave, the distance traveled in one full cycle is equal to the wavelength λ, and the time taken to complete one such cycle is the time period T. Using the fundamental speed formula v = ᵈⁱˢᵗᵃⁿᶜᵉ⁄ₜᵢₘₑ, we substitute these values to get wave velocity v = (λ)/(T). This expression represents the rate at which the wave profile moves through the medium.

Explanation

The first slip is a specialized fielding position located on the off-side, immediately adjacent to the wicket-keeper. This position is part of the slip cordon, which is strategically placed in an arc behind the striker's stumps to catch balls that deflect off the edge of the bat.

Explanation

Convergent plate boundaries occur where two tectonic plates move toward each other and collide. When two continental plates converge, the relatively low density of the continental crust prevents it from subducting deep into the mantle. Instead, the intense pressure causes the crust to buckle, fold, and thicken. This geological process, known as orogenesis, results in the uplift of the earth's surface to form massive fold mountain ranges, such as the Himalayas created by the collision of the Indian and Eurasian plates. Even in oceanic-continental convergence, the compressive forces and associated volcanic activity lead to the formation of mountain chains along the plate margins.
