Question

What is an example of a hypothesis that may explain species of the class Reptilia are rarely found in polar regions?

Answer 1

Answer) Hypothesis; Thermoregulation in cold-blooded animals.

Explanation- As we know that reptiles are cold-blooded animals and they can not internally adjust their body temperature. so they need to bask in sun to warm their body in col environment. this process of regulating body temperature according to the season or environment is called as thermoregulation. also, we know that polar regions are extremely cold with very low or no sunlight for longer duration every year. in such extreme cold weather, reptiles can't adjust their body temperature. this is the best possible hypothesis for the fact that species of class Reptilia are rarely found in polar regions.
