Detailed Solution for AFMC Biology Mock Test - 3 - Question 26

Some animals maintain their body temperature within a narrow range.
There are two types of animals- Endotherms and Ectotherms.
Endotherms:- They use internal heat to maintain their body temperature. This internal temp. is independent of outside temperature.Examples include mammals and birds.
Ectotherms:-These organisms are not able to maintain their own body temp. so they depend on external environment. Example-snakes,amphibians,reptiles,fish.
So the frog's[as it is a amphibian] body temp. in the new environment would be 30 centigrade.
