    Correct Answer: Infrared waves are largely absorbed by water vapor that is concentrated in the lower atmosphere.

    Explanation:

    1. “The total amount of insolation received at the equator is roughly about 10 times that received at the poles.”
      Incorrect.
      While there is a significant difference in insolation between the equator and the poles due to the angle of incidence of solar radiation, it is not as extreme as 10 times. The actual difference is much smaller, generally ranging from 2 to 3 times.
    2. “Infrared rays constitute roughly two-thirds of insolation.”
      Incorrect.
      Infrared rays are part of the electromagnetic spectrum, but they only constitute a small portion of the incoming solar radiation (insolation). The majority of insolation consists of visible light and ultraviolet radiation.
    3. “Infrared waves are largely absorbed by water vapor that is concentrated in the lower atmosphere.”
      Correct.
      Infrared waves, which are long-wavelength radiation, are absorbed by greenhouse gases such as water vapor, carbon dioxide, and methane. Water vapor, concentrated in the lower atmosphere (troposphere), plays a major role in absorbing and trapping infrared radiation, contributing to the greenhouse effect.
    4. “Infrared waves are a part of the visible spectrum of electromagnetic waves of solar radiation.”
      Incorrect.
      Infrared waves are not part of the visible spectrum. The visible spectrum includes wavelengths between 400-700 nanometers, whereas infrared waves are longer than this range and are not visible to the human eye.

    Biofilters play a crucial role in Recirculating Aquaculture Systems by eliminating nitrogenous waste produced by aquatic organisms. They utilize nitrifying bacteria to transform toxic ammonia into nitrites, which are also harmful. Subsequently, other bacteria further convert these nitrites into harmless nitrates, ensuring water quality. Importantly, biofilters are engineered to remove pollutants rather than introduce nutrients into the system, making statement 3 inaccurate.

    Correct Answer: All three

    Explanation:

    1. Gold mining activity is a source of mercury pollution in the world:
      Correct. Artisanal and small-scale gold mining (ASGM) is one of the largest global sources of mercury emissions. Mercury is used in the extraction process to amalgamate gold, releasing significant amounts of mercury into the environment.
    2. Coal-based thermal power plants cause mercury pollution:
      Correct. Coal contains trace amounts of mercury. When coal is burned in thermal power plants, mercury is released into the atmosphere as a pollutant.
    3. There is no known safe level of exposure to mercury:
      Correct. Mercury is highly toxic, and even low levels of exposure can lead to serious health effects. The World Health Organization (WHO) states that there is no safe threshold for mercury exposure, particularly for vulnerable groups such as pregnant women and children.

    Hence, all three statements are correct.

    Let’s analyze each statement to determine its correctness:

    1. Some mushrooms have medicinal properties: This is true. Certain mushrooms, such as Reishi and Shiitake, are known for their medicinal benefits, including immune-boosting and anti-inflammatory properties.
    2. Some mushrooms have psychoactive properties: This is also true. Psilocybin mushrooms, often called “magic mushrooms,” contain psychoactive compounds that can alter perception and mood.
    3. Some mushrooms have insecticidal properties: True. Some fungi, like Beauveria bassiana, produce compounds that act as natural insecticides, infecting and killing various insect species.
    4. Some mushrooms have bioluminescent properties: True as well. Certain mushrooms, such as Panellus stipticus and Mycena chlorophos, exhibit bioluminescence and emit a glowing light.

    All four statements are correct. Therefore, the correct answer is: All four

    Let’s analyze each statement:

    Statement-I: India, despite having uranium deposits, depends on coal for most of its electricity production. This statement is correct. Although India has some uranium deposits, they are not sufficient to meet the country’s nuclear energy needs. As a result, India imports uranium and heavily relies on coal, which is abundant and cheaper, for most of its electricity production.

    Statement-II: Uranium, enriched to the extent of at least 60%, is required for the production of electricity. This statement is incorrect. For nuclear reactors used in electricity production, uranium is typically enriched to about 3-5% U-235. Enrichment levels of 60% and above are considered high and are used for research reactors or weapons-grade material, not for commercial electricity generation.

    Therefore, the correct answer is: Statement-I is correct but Statement-II is incorrect.

    Let’s evaluate the above statements:

    1. Amarkantak Hill:
      • Recognized as a significant natural heritage site.
      • Serves as the junction of the Vindhya and Satpura Ranges.
      • Therefore, statement 1 is INCORRECT.
    2. Biligirirangan Hills:
      • Located in the southeastern region of Karnataka.
      • The Satpura Range, in contrast, begins in eastern Gujarat and extends eastward, bordering Maharashtra and Madhya Pradesh, ultimately reaching Chhattisgarh.
      • Hence, statement 2 is INCORRECT.
    3. Seshachalam Hills:
      • Part of the Eastern Ghats in southern Andhra Pradesh.
      • The Western Ghats, however, span across several states including Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra, and Gujarat.
      • Thus, statement 3 is INCORRECT.

    Therefore, the correct answer is None.

    Statement Breakdown:

    1. It is a safe motherhood intervention of the State Health Departments:
      • Incorrect: The Janani Suraksha Yojana (JSY) is a centrally sponsored scheme under the National Rural Health Mission (NRHM) of the Union Ministry of Health & Family Welfare, not solely managed by state health departments. While it is implemented at the state level, it is a central government initiative.
    2. Its objective is to reduce maternal and neonatal mortality among poor pregnant women:
      • Correct: The main goal of JSY is indeed to reduce maternal and neonatal mortality, particularly among poor pregnant women by promoting institutional deliveries. It focuses on vulnerable groups in rural areas.
    3. It aims to promote institutional delivery among poor pregnant women:
      • Correct: One of the key objectives of JSY is to encourage institutional delivery, particularly for women in rural areas, by providing financial assistance to them.
    4. Its objective includes providing public health facilities to sick infants up to one year of age:
      • Incorrect: JSY focuses on safe motherhood and institutional delivery for pregnant women, not directly on providing public health services to sick infants. The scheme does not target infant care up to one year of age.

    Based on the corrected analysis, statements 2 and 3 are correct, while statements 1 and 4 are incorrect.

    Thus, the correct answer is Only two.

    Here’s a breakdown of the statements in the context of the Anaemia Mukt Bharat (AMB) Strategy:

    1. Prophylactic calcium supplementation:
      • Incorrect: AMB focuses on iron and folic acid supplementation, not calcium supplementation. Calcium supplementation is addressed under other maternal and child health programs.
    2. Campaign for delayed cord clamping at the time of childbirth:
      • Correct: Delayed cord clamping is promoted as part of AMB to ensure improved iron stores in newborns, which helps prevent anaemia.
    3. Periodic deworming for children and adolescents:
      • Correct: AMB includes periodic deworming to address parasitic infections, a significant cause of anaemia in children and adolescents.
    4. Addressing non-nutritional causes of anaemia:
      • Correct: AMB recognizes non-nutritional causes such as malaria, hemoglobinopathies, and fluorosis in endemic areas and includes measures to address them.

    Thus, statements 2, 3, and 4 are correct, and only statement 1 is incorrect.

    The correct answer is It defines and limits the powers of government.

    Explanation: The primary purpose of a constitution is to establish the fundamental framework for governance in a country. It defines the structure of the government, delineates the powers and functions of different institutions, and places limits on governmental power to protect individual rights and maintain the rule of law. While it may also outline the objectives for making laws, create political offices, and aim to secure social justice, its chief purpose is to define and limit the powers of government to prevent abuse and ensure the protection of citizens’ rights.
