Question

All reptiles regulate their body temperature from external sources of heat.

a) True
b) False

Answer 1

False. Reptiles regulate their body temperature from external sources of heat, such as the sun or the environment around them. They do this through behavioral adaptations like basking in the sun to warm up or seeking shade to cool down.

Step-by-step explanation:

False. All reptiles are ectotherms, which means they regulate their body temperature from external sources of heat, such as the sun or the environment around them. They do this through behavioral adaptations like basking in the sun to warm up or seeking shade to cool down. Unlike endotherms, which can generate heat internally and maintain a constant body temperature, reptiles rely on external sources of heat to regulate their body temperature.
