|
When a person is extremely cold, his or her muscles will use energy to spasm and generate heat, the act of shivering. Which conclusion best explains why the body does this?
|
|
The body maintains homeostasis by keeping the body at a specific temperature.
|
|
|
The body tricks the mind into thinking it is not cold so that it can maintain homeostasis.
|
|
|
The body maintains homeostasis by releasing water to maintain the muscles’ temperature.
|
|
|
The body loses mass through shivering so that it can better maintain homeostasis.

Explanation:
Detailed explanation-1: -Humans exhibit two major physiological responses to cold exposure. Peripheral vasoconstriction limits heat loss. Shivering, physical activity, or both increase heat production.
Detailed explanation-2: -When the body can no longer maintain core temperature by constricting blood vessels, it shivers to increase heat production. Skeletal muscles contract to generate heat.
