Question 1 of 5
1. Question
Consider the following statements with respect to ‘Seagrasses’
- Seagrasses are flowering plants that grow submerged in shallow marine waters like bays and lagoons
- The temperate waters of the Atlantic hold the highest diversity of seagrasses in the world
- Seagrasses undergo photosynthesis and manufactures their own food and produce oxygen
Choose the correct answer using the code given below
Correct
Solution (c)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Correct Incorrect Correct Seagrasses are the only flowering plants which grow in marine environments. Seagrasses are flowering plants that grow submerged in shallow marine waters like bays and lagoons. Seagrasses have roots, stems, and leaves and produce flowers and seeds. The tropical waters of the Indo-Pacific hold the highest diversity of seagrasses in the world, supporting 14 different species. This is probably because seagrasses evolved first in this part of the world Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Context – A species of marine seagrass found in the Mandapam region near Rameswaram, Tamil Nadu has the potential to be used in chemotherapy treatment for liver cancer according to a study.

Question 2 of 5
2. Question
With reference to ‘Atacama Large Millimetre/submillimetre Array (ALMA) Telescope’, consider the following statements
- ALMA can provide insights on star birth and detailed imaging of local star and planet formation.
- It is a part of the Event Horizon Telescope project, a large telescope array consisting of a global network of radio telescopes
Select the correct statement(s)
Correct
Solution (c)
Statement Analysis:
Statement 1 Statement 2 Correct Correct The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of 66 radio telescopes in the Atacama Desert of northern Chile, which observe electromagnetic radiation at millimeter and submillimeter wavelengths. ALMA provides insight on star birth during the early Stelliferous era and detailed imaging of local star and planet formation ALMA is an international partnership amongst Europe, the United States, Canada, Japan, South Korea, Taiwan, and Chile. As part of the Event Horizon Telescope project, a large telescope array consisting of a global network of radio telescopes, it provided the first image of the supermassive black hole at the centre of our own Milky Way galaxy. Context – The Atacama Large Millimetre/submillimetre Array (ALMA), a radio telescope comprising 66 antennas is set to get software and hardware upgrades.

Question 3 of 5
3. Question
‘Pink Bollworm’ a pest seen in news is mostly known for affecting
Correct
Solution (b)
The pink bollworm is an insect known for being a pest in cotton farming. The adult is a small, thin, gray moth with fringed wings. The pink bollworm is native to Asia, but has become an invasive species in most of the world’s cotton-growing regions. In parts of India, the pink bollworm is now resistant to first generation transgenic Bt cotton (Bollgard cotton) that expresses a single Bt gene (Cry1Ac).
Context – The Genetic Engineering Appraisal Committee (GEAC) recently approved confined field trials for Pink Bollworm-resistant GM cotton in Hisar, Haryana

Question 4 of 5
4. Question
With reference to ‘Atmanirbhar Clean plant program’, consider the following statements
- The program will aim to enhance the yield of horticulture crops and protect the ecosystem through proactive virus and disease control measures
- The program will be anchored by National Institute of Plant Health management which in turn will set up Clean Plant Centres across the country
Select the correct statement(s)
Correct
Solution (a)
Statement Analysis:
Statement 1 Statement 2 Correct Incorrect The clean plant programme will aim to enhance the yield of horticulture crops, dissemination and adoption of climate resilient varieties; protect the ecosystem through proactive virus and disease control measures. The centres will work with the stakeholders so that they adopt clean plant seeds and nurseries. The national horticulture board may also tie up with the Asian Development Bank The outlay of the new programme will be Rs. 2,200 crore. The programme will be anchored by the national horticulture board which in turn will set up Clean Plant Centres across the country. These centres will ensure access to disease-free horticulture planting material for the global competitiveness of Indian horticulture sector. Context – In order to increase domestic production, the Center plans to establish 10 “Clean Plant Centers” as the demand for fruits like apple, avocado and blueberry has increased over time.

Question 5 of 5
5. Question
Consider the following factors
- Warmer Arabian Sea
- Direction of wind flow
- Upper atmospheric westerly winds
- Increasing lapse rate
- Expansion of air
Which of the factor(s) given above are the causes of heat wave in Indian context
Correct
Solution (d)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Statement 4 Statement 5 Correct Correct Correct Incorrect Incorrect The air flowing in over the oceans is expected to bring cooler air, since land warms faster than the oceans. However, this does not happen as the Arabian Sea is warming faster than most other ocean regions. In spring, India typically has air flowing in from the west-northwest. The Middle East is warming faster than other regions in latitudes similarly close to the equator, and serves as a source of the warm air that blows into India. The strong upper atmospheric westerly winds that come in from the Atlantic Ocean over to India during spring control the near-surface winds. The energy to run past the earth near the surface, against the surface friction, can only come from above. This descending air compresses and warms up to generate some heat waves. It should be noted that the lapse rate is declining under global warming In other words, global warming tends to warm the upper atmosphere faster than the air near the surface. Hence, the sinking air is warmer due to global warming, and thus produces heat waves as it sinks and compresses. Air flowing in from the northwest rolls in over the mountains of Afghanistan and Pakistan. As a result, some of the compression also happens on the leeward side of these mountains, entering India with a bristling warmth. Context – The India Meteorological Department (IMD) warned that the maximum temperatures over northwest, west, and central India would be 3-5° C higher than the long-term average.
