Question

Body temperature of cold blooded animals

(a) is constant

(b) fluctuates with surrounding temperature

(c) becomes very low at times

(d) is very cold.

Answer 1

The correct option is: (b) fluctuates with surrounding temperature

Explanation:

Cold blooded animals do not have any temperature regulating mechanism or homeostasis. Thus, their body temperature fluctuates with the environmental temperature. It is seen mostly in lower group of vertebrates. They make their own physiological mechanism (like hibernation/ diapause) to get rid of the extremity of temperature.
