The correct answer is: d) Absorbing light

Explanation: Chlorophyll plays a crucial role in photosynthesis by absorbing light energy from the sun. It is a green pigment found in the chloroplasts of plant cells and is primarily responsible for capturing light energy, which is then used to drive the process of photosynthesis. Specifically, chlorophyll absorbs light in the blue and red wavelengths and reflects green light, which is why plants appear green.

The absorbed light energy is converted into chemical energy, which is used to synthesize glucose from carbon dioxide (CO2) and water (H2O). While chlorophyll is not directly involved in reducing CO2 or breaking down water molecules, it facilitates these processes by providing the energy required for them.

Correct Answer: a) Nomination of them has been done away with by 104th Constitutional Amendment

Explanation:

a) Nomination of them has been done away with by 104th Constitutional Amendment: This is the correct answer. The 104th Constitutional Amendment Act, passed in January 2020, abolished the provision for the nomination of Anglo-Indians to the Lok Sabha and State Legislative Assemblies. Prior to this amendment, two members of the Anglo-Indian community were nominated to the Lok Sabha by the President under Article 331 of the Constitution. This provision was removed as part of the amendment.

b) Two Anglo-Indians are nominated by the President: This was true before the 104th Constitutional Amendment. However, after the amendment, this provision no longer exists.

c) They are nominated as per their population: This is incorrect. The nomination of Anglo-Indians was never based on their population. It was a special provision under Article 331 to ensure representation for the community.

d) One Anglo-Indian is nominated by the President: This is incorrect. Before the 104th Amendment, two Anglo-Indians were nominated, not one.

Correct Answer: c) Appraisal of the Act of 1935

Explanation: The Government of India Act, 1935, was a significant constitutional reform introduced by the British government. Let us analyze the options:

a) Reconstruction of the Governor-General’s Executive Council: This was indeed a feature of the Act. The Governor-General’s Executive Council was restructured to include more Indian members, though the Governor-General retained overriding powers.

b) Provincial Autonomy: This was a major feature of the Act. It granted autonomy to provinces, allowing them to function as independent administrative units in certain areas, though the Governor still had significant powers.

c) Appraisal of the Act of 1935: This is not a feature of the Act. The Act itself was a legislative framework and did not include any provision for its appraisal.

d) Proposal for Federation of India: The Act proposed a federation that would include both British India and princely states. However, this proposal was never fully implemented because the princely states did not agree to join.

Correct Answer: b) 1.4 kW/m²

Explanation:

The solar constant is the amount of solar energy received per unit area at the outer edge of Earth’s atmosphere, when the Earth is at an average distance from the Sun. Its value is approximately 1.4 kW/m² (or 1361 W/m²).

This value represents the intensity of solar radiation reaching a surface perpendicular to the Sun’s rays in space, before any atmospheric absorption or scattering occurs. It is a critical parameter in understanding Earth’s energy balance and climate.

Thus, the correct answer is 1.4 kW/m².

Correct Answer: c) Sir Austin Chamberlain

Explanation:

The Royal Commission on Indian Currency and Finance, also known as the Chamberlain Commission, was appointed in 1913 to examine and make recommendations regarding the Indian currency system. It was headed by Sir Austin Chamberlain, who was a prominent British statesman and had previously served as the Secretary of State for India.

The commission’s primary focus was on the monetary system of India, particularly the functioning of the gold exchange standard that had been introduced in the late 19th century.
