Explanation

Rabi crops are sown in the winter season, usually between October and December, and harvested in the spring months of March to May. These crops require a cool climate during their growing period and a warmer climate for seed germination and harvesting. Barley and gram are both cultivated during this winter cycle. Barley is a hardy cereal grain adapted to temperate climates, while gram, or chickpea, is a significant pulse crop that depends on the residual soil moisture and cool temperatures typical of the Indian winter. Both are major constituents of the rabi harvest in the northern and central regions of the country.

Explanation

Zooplankton are heterotrophic organisms that drift or swim in the water column of aquatic ecosystems. They are categorized by their movement and life cycles, which often encompass both free-swimming and bottom-dwelling phases. A significant portion of zooplankton, known as meroplankton, consists of the larval stages of various benthic organisms such as crustaceans, mollusks, and echinoderms. These organisms exist as free-swimming forms in the open water to facilitate dispersal before settling on the sea floor to live as bottom-dwelling adults. Additionally, many zooplanktonic species engage in diel vertical migration, where they swim through the water column at night and retreat to bottom-dwelling or deep-water zones during the day to avoid predators.

Ustad Abdul Karim Khan was the co-founder and most prominent exponent of the Kirana Gharana, one of the most prolific lineages of Hindustani classical music. Born in Kairana, a small town in Uttar Pradesh, he developed a style that shifted the focus of khayal singing from rhythmic complexities to melodic purity and emotional expression. His approach emphasized the precise intonation of individual notes, known as swara-shuddhi, and introduced a slow, meditative method of raga development. Along with his cousin Ustad Abdul Wahid Khan, he established the unique identity of this school, which is celebrated for its soulful alaaps and high-pitched vocal delivery. His influence extended significantly to the Carnatic tradition as well, and he is often credited with bridging the musical gap between North and South India.

Explanation

A polysome, or polyribosome, is a structural complex that forms when multiple ribosomes attach to a single strand of messenger RNA (mRNA) during the process of translation. This arrangement allows for the simultaneous synthesis of several copies of the same protein from a single mRNA template, significantly increasing the efficiency of protein production within the cell. Each ribosome in the group moves along the mRNA molecule independently, translating the genetic sequence into a polypeptide chain. Under an electron microscope, these clusters appear like a string of beads, where the mRNA acts as the thread connecting the individual ribosomal units.

Explanation

Article 28 regulates religious instruction or worship in certain educational institutions, prohibiting it in those entirely maintained by State funds while allowing individuals to choose whether to participate in such activities in other recognized institutions. Together, these articles form the constitutional framework for religious pluralism and secularism in India.

Explanation

Wealth tax is classified as a direct tax because it is levied directly on the net wealth and personal assets of an individual or a legal entity. In direct taxation, the incidence and impact of the tax fall on the same person, meaning the tax burden cannot be shifted to another party. The government collects this tax based on the value of assets held, such as property, jewellery, and shares. While wealth tax was officially abolished in India through the Union Budget of 2015 and replaced with a surcharge on high-income individuals, it remains a fundamental example of direct taxation in economic principles, distinct from taxes levied on the consumption of goods or services.

Explanation

The SI unit of electric charge is the coulomb, represented by the symbol C. It is a derived unit defined in terms of the ampere, which is the SI base unit for electric current. One coulomb is the quantity of electric charge transported by a constant current of one ampere in one second. This relationship is defined by the formula Q = I × t, where Q is the electric charge in coulombs, I is the electric current in amperes, and t is the time in seconds. Under the current SI definitions, the coulomb is also fundamentally linked to the elementary charge e, which is the charge of a single proton.

Explanation

In a landmark judgment in September 2022, the Supreme Court of India ruled that all women, regardless of their marital status, are entitled to safe and legal abortion up to 24 weeks of pregnancy. The court held that excluding unmarried women in consensual relationships from the benefit of the Medical Termination of Pregnancy (MTP) Rules, which allowed abortion between 20 to 24 weeks for certain categories, was discriminatory and unconstitutional. This decision emphasized that the right to reproductive autonomy, dignity, and privacy gives every woman the right to choose whether or not to carry a pregnancy to term, effectively extending the 24-week limit to unmarried women who were previously restricted to 20 weeks.

Explanation

Article 120 of the Constitution of India specifically mandates that the business of Parliament shall be transacted in Hindi or in English.

The classification is determined by the boxer's year of birth relative to the year the competition is held. This category serves as the intermediate competitive level between the Junior category, which includes 15 and 16-year-olds, and the Elite category, which comprises boxers aged 19 to 40. Participants in the Youth category compete in sanctioned international tournaments to prepare for senior-level competition.

Explanation

The M phase, or mitotic phase, is the period of actual cell division where the cell reorganizes its components to distribute DNA and cytoplasm into two daughter cells. This phase consists of mitosis (nuclear division) and cytokinesis (cytoplasmic division). Physical growth, the synthesis of proteins, and the duplication of organelles occur during the interphase, specifically during the G₁ and G₂ stages. During the M phase, metabolic activity is redirected toward the mechanical processes of chromosome segregation and structural division, meaning the cell does not grow physically larger or copy its organelles during this specific time.

Explanation

The Green Revolution in India, initiated in the mid-1960s under the leadership of M.S. Swaminathan, was fundamentally driven by the introduction of High Yielding Variety (HYV) seeds for both wheat and rice. The program first saw success with the introduction of semi-dwarf wheat varieties like Sonora 64 and Lerma Rojo, which were developed by Norman Borlaug in Mexico. This was followed by the introduction of HYV rice seeds, most notably the IR8 variety developed at the International Rice Research Institute in the Philippines. These seeds were designed to be more responsive to chemical fertilizers and required controlled irrigation, leading to a dramatic increase in crop yields. The combined adoption of these HYV wheat and rice seeds enabled India to achieve food security and significantly reduce its dependence on grain imports.

Explanation

The rules of tennis define a completed set based on a player reaching a minimum of six games with a lead of at least two games over their opponent. A score of 6-4 fulfills these requirements perfectly, as the leading player has secured the necessary six games and holds a two-game advantage. This scoring follows the standard set format used in most professional tournaments, where reaching six games with a two-game margin concludes the set immediately without requiring additional games or a tie-break procedure.

Explanation

Pepsin is a primary protease or protein-digesting enzyme produced in the stomach. It is secreted by the gastric chief cells in an inactive precursor form known as pepsinogen. When pepsinogen encounters the acidic environment of the stomach created by hydrochloric acid, it undergoes a conformational change to become active pepsin. Once activated, pepsin functions to break down large, complex protein molecules into smaller fragments called peptides and proteoses. This process occurs through the hydrolysis of peptide bonds, specifically targeting those involving aromatic amino acids like phenylalanine, tryptophan, and tyrosine. Pepsin is essential for the initial stages of protein catabolism in the vertebrate digestive system.

Explanation

Shyamji Krishna Varma established India House in London in 1905 to serve as a hostel for Indian students and a focal point for revolutionary activities in the United Kingdom. It was founded alongside the Indian Home Rule Society to advocate for Indian self-rule and became a crucial hub for prominent nationalists like V.D. Savarkar, Lala Hardayal, and Madan Lal Dhingra. From this base, Varma published the journal The Indian Sociologist to spread anti-colonial sentiment and organize Indian students against British imperial policies. The establishment provided scholarship opportunities for Indian students to study in Britain while simultaneously fostering a sense of national identity and political consciousness among the diaspora.

Explanation

Uniform motion is defined as the motion of an object in which it travels in a straight line and its velocity remains constant over time. Since velocity is a vector quantity, a constant velocity signifies that both the speed of the object and its direction of motion do not change. Mathematically, if the velocity v is constant, the acceleration a = d{v}{dt} is zero. This ensures that the object covers equal displacements in equal intervals of time, which is the fundamental characteristic of uniform motion.

Explanation

Thorny bushes are a characteristic feature of dry desert regions where annual rainfall is extremely low and evaporation rates are high. These plants, known as xerophytes, have evolved specific adaptations to survive in arid environments. The presence of thorns or spines instead of leaves is a primary adaptation to reduce the surface area through which water is lost via transpiration. Furthermore, these plants often have thick, waxy cuticles and deep-reaching root systems to maximize water absorption and storage. Such vegetation is commonly found in tropical and subtropical deserts where the scarcity of moisture limits the growth of large trees and lush foliage.

Explanation

The Bay of Bengal is the primary region for the origin of tropical cyclones that affect the Indian subcontinent. It exhibits high sea surface temperatures, often remaining above 28°C, which provide the necessary latent heat and energy for cyclogenesis. The basin's semi-enclosed nature and the influx of fresh water from major river systems create a stratified surface layer that inhibits the upwelling of cooler subsurface water, allowing the surface to remain warm and fuel storm intensification. Geographically, the Bay of Bengal is also influenced by remnant low-pressure systems moving in from the South China Sea, which frequently re-intensify into tropical cyclones upon entering these warm waters, leading to a higher frequency of cyclonic activity compared to other surrounding maritime regions.

Explanation

According to the 2011 Census, the population density of Chandigarh is approximately 9,258 persons per square kilometer, which is significantly higher than that of Puducherry (2,547), Bihar (1,106), and Uttar Pradesh (829).

Explanation

Limestone is classified as a biological or organic sedimentary rock because it primarily forms from the accumulation of organic debris. In marine environments, various organisms such as corals, shellfish, and microscopic algae extract calcium carbonate (CaCO₃) from the water to construct their shells and skeletal structures. When these organisms die, their hard remains settle on the ocean floor. Over vast periods of time, these layers of organic material undergo compaction and lithification to become solid rock. While limestone can also form through direct chemical precipitation from water, the vast majority of the world's limestone deposits are biogenic in origin, consisting of the fossilized remains of ancient marine life.
