Answer: They are exposed to different environments
When animals are isolated from each other and put in different environments, they react to their environment differently and this causes them to adapt differently.
Endothermic: accompanied by or requiring the absorption of heat....EX: baking bread, water evaporation, melting an ice cube.
Exothermic: accompanied by the release of heat....EX: formation of ice cube, hot iron, melting solid salts.
Answer: Option A
Explanation:
Homeostasis can be defined as the condition in which the body maintains the equilibrium inside the body with respect to the changing environment.
Maintaining the adequate amount of oxygen in the body is also a part of homeostasis.
When the oxygen level in the body goes below normal then the heart rate of the body increases. This supplies more oxygen and the level in the body is maintained.
This condition is an example of homeostasis in the human body.
