Assertion : Ectotherms are able to remain active under cold conditions.
Reason : Ectotherms are able to maintain a constant internal temperature, even when the temperature outside fluctuates.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
D. If both assertion and reason are false.
Step-by-step solution
Ectotherms or cold-blooded animals, cannot regulate their body temperature and are unable to maintain a constant internal temperature. Their body temperature tends to match with the environmental temperature in which they live, (e.g., frogs and snakes). These animals are not able to remain active under cold conditions.
