Question

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

Explanation:

Shivering is an involuntary response that generates heat to keep body temperature stable, which is part of maintaining homeostasis (the body's ability to regulate internal conditions). It does not reduce movement, nor is it related to blood glucose regulation.

Answer:

maintaining homeostasis by regulating body temperature
