1.	Which is the adaptive radiation is used by poikilotherms to protect against extreme heat?(a) Migration(b) Cooling(c) Aestivation(d) HibernationThe question was asked in examination.This intriguing question comes from Organisms and Populations topic in chapter Organisms and Populations of Biology – Class 12
Answer» The correct option is (c) AESTIVATION For explanation: The poikilotherms use aestivation as a protective mechanism against EXTREME HEAT. The suspension of metabolic activities during summer is called aestivation. It helps in maintaining body temperature and avoids water LOSS in mostly cold-blooded animals such as snails, bees, tortoise, crocodile, etc.
