Question

Assertion (A): Acclimatisation is the gradual physiological adjustment of an organism in the slowly changing new environmental conditions.

Reason (R): An organism undergoes morphological, physiological and behavioural adaptations to survive well in an environment.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

Explanation:

Both statements are true. Acclimatisation is specifically a gradual physiological adjustment; the reason describes broader ecological adaptations and does not explain that definition.
