Question 1
The 42nd Amendment Act 1976 imposed a freeze on the population figure for readjustment at the 1971 census and has been extended by the 84th Amendment Act 2001 till 2026. As a result, the House of the People today represents the population figure of the 1971 census. For what purpose has the freeze on undertaking delimitation been extended up to the year 2026?
A
To enable State Governments to pursue the agenda for population stabilisation
B
To ensure continuity in developmental programmes for periods longer than the interval between successive censuses
C
To avoid unnecessary expenditure that the exchequer would incur due to the associated costs of increased number of people's representatives in both the centre and state governments
D
None of the above
EVS Questions answers

Question 1 Explanation: 

The same question was posted here earlier.

  • The Statement of Objects and Reasons to the Constitution (84th Amendment) Act, 2001 states, "There have been consistent demands, both for and against undertaking the exercise of fresh delimitation. Keeping in view the progress of family planning programmes in different parts of the country, the Government, as part of the National Population Policy strategy, recently decided to extend the current freeze on undertaking fresh delimitation up to the year 2026 as a motivational measure to enable the State Government to pursue the agenda for population stabilisation."
  • Ch-22, Indian Polity by M Laxmikanth: "This ban on readjustment was extended for another 25 years (ie, upto year 2026) by the 84th Amendment Act of 2001, with the same objective of encouraging population limiting measures."

Question 2
With reference to ecological balance, consider the following statements:
  1. Ecological balance can happen when the diversity of the living organisms remains relatively stable.
  2. The stability of an ecosystem always increases with the introduction of new species.
Which of the above statements is/are correct?
A
1 only
B
2 only
C
Both 1 and 2
D
Neither 1 nor 2
GK Questions answers

Question 2 Explanation: 

Introduction of new species into the ecosystem often cause disruption in stability of ecosystem. For ex: Presence of alien species like lantana in tropical deciduous forest has resulted in frequent forest fires.

Question 3
Consider the following statements with respect to 'Elastocaloric effect'
  1. In the elastocaloric effect, the transfer of heat works much the same way as when fluid refrigerants are compressed and expanded.
  2. A good elastocaloric material must exhibit a large latent heat, and a large adiabatic temperature change.
Select the correct statements
A
1 Only
B
2 Only
C
Both
D
None
Microbiology Questions answers

Question 3 Explanation: 
Elastocaloric materials are solids capable of stress-induced reversible phase transformations during which latent heat is released or absorbed. The elastocaloric effect occurs when stress is applied or removed, and a phase transformation is induced. As a result of the entropy difference between the two co-existing phases, the material heats up or cools down. A good elastocaloric material must exhibit a large latent heat, a large adiabatic temperature change, good thermal conductivity, long fatigue life, and low cost. Shape memory polymers can also exhibit elastocaloric effect.

Printing money just for meeting a deficit creates over flow of money into the market creating hyperinflation. So, RBI usually don't take such measure.

Question 5
Consider the following statements regarding solar cell.
  1. Solar cells can generate electricity irrespective of whether the source is sunlight or an artificial light.
  2. Solar cells are made of crystalline silicon only.
Which of the statements given above are correct.
A
1 only
B
2 only
C
Both 1 and 2
D
Neither 1 nor 2
Home science Questions answers

Question 5 Explanation: 
Solar cells are described as being photovoltaic, irrespective of whether the source is sunlight or an artificial light. So statement 1 is correct.

Solar cells can be classified into first, second and third generation cells. The first generation cells also called conventional, traditional or wafer-based cells are made of crystalline silicon, Second generation cells are thin film solar cells, made of amorphous silicon, third generation cells are comprised of often organometallic compounds as well as inorganic substances. So statement 2 is incorrect.
