    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: 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.

With reference to ‘Scheduled Areas’ in India, consider the following statements:                   [2023]
1. Within a State, the notification of an area as Scheduled Area takes place through an Order of the President.
2. The largest administrative unit forming the Scheduled Area is the District and the lowest is the cluster of villages in the Block.
3. The Chief Ministers of the concerned States are required to submit annual reports to the Union Home Ministry on the administration of Scheduled Areas in the States.

    Statement 1 is accurate since, under Schedule V (Article 244) of the Indian Constitution, the President is empowered to declare specific regions as Scheduled Areas. Paragraph VI of the Fifth Schedule explicitly states that the term “Scheduled Areas” refers to those areas that the President may declare through an official order.

    Statement 2 is also correct. In April 2018, the Union Cabinet approved the declaration of certain areas in Rajasthan as Scheduled Areas under the Fifth Schedule. This included three entire districts—Banswara, Dungarpur, Pratapgarh—along with nine complete tehsils, one block, and 46 full gram panchayats across multiple districts like Udaipur, Rajsamand, Chittorgarh, Pali, and Sirohi. It is important to note that while a block can consist of a cluster of villages, individual villages from within a block can be grouped together to form the smallest administrative unit within the Scheduled Areas framework.

    Statement 3 is incorrect. According to the Constitution, the Governor of a state with Scheduled Areas is responsible for submitting annual reports to the President regarding the management and governance of those areas. Additionally, the President may require such a report at any time. Furthermore, the Union Government holds the authority to issue directions to state governments regarding the administration of these areas.

    Therefore, the correct answer is Only two.

    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

    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.

    India possesses substantial reserves of heavy minerals predominantly located along its coastal regions and in inland placer deposits. These heavy mineral sands include a collection of seven key minerals: ilmenite, leucoxene (also known as brown ilmenite), rutile, zircon, sillimanite, garnet, and monazite. Among these, ilmenite (FeO.TiO₂) and rutile (TiO₂) are the principal sources of titanium. Titanium dioxide is found in various polymorphic forms, namely rutile, anatase (octahedrite), and brookite. The correct answer is: Titanium.
