Some animals shiver as a natural, involuntary response to their environment. shivering generates heat. this is an example of which function? reducing movement to regulate body temperature reducing movement to regulate blood glucose maintaining homeostasis by regulating body temperature maintaining homeostasis by regulating blood glucose

maintaining homeostasis by regulating body temperature

Explanation:

Homeostasis is the ability of the body to restrict any change occurring in the body with respect to the changes occurring in the external environment. It is the tendency of the body to maintain equilibrium with the outer environment.

The animals will shrivel in response to the external environment. The shriveling will release heat by the movement of muscles. This process will support the animals in maintaining the internal temperature of the body. Hence, it will help the animals in maintaining the homeostasis.
