Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Most of the poikilothermic animals are thermo-conformers in nature.
Reason (R) : Poikilothermic animals can maintain constant body temperature with ambient temperature.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is incorrect.
• D. (A) is incorrect but (R) is correct.

Hint:

Poikilotherms cannot keep a constant body temperature, so they conform to the environment.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Thermoconformers have a body temperature that changes with the surroundings, while thermoregulators keep it constant.

Step 2: Assertion (A)
Most poikilothermic animals do not regulate their body temperature, so they are thermoconformers. (A) is correct.

Step 3: Reason (R)
Poikilotherms cannot maintain a constant body temperature with respect to ambient temperature. Constant temperature is a feature of homeotherms. (R) is incorrect.

Step 4: Compare the options
(A) is correct but (R) is incorrect.

Final Answer:
(A) is correct but (R) is incorrect. \[ \boxed{\text{(C) }\text{(A) is correct but (R) is incorrect}} \]
