Question

describing how the body maintains homeostasis produces heat in the body and is observed as shivering. the brain also sends signals to the muscles right beneath the skin. these muscles shorten and tighten, causing the hairs on the skin to stand up. when the hairs stand up, heat is kept in the air trapped within the hairs, which keeps the body warm. what did you include in your response? check all that apply. the nervous system and the muscular system work together. muscles move rapidly to produce heat within the body. muscles underneath the skin contract, causing hair on the skin to stand up. when hairs on skin stand up, they trap the heat coming out of the body so the heat is kept near the body.

Explanation:

The text describes how the body maintains homeostasis in terms of temperature - regulation. It mentions the nervous system signaling muscles, muscle - movement for heat production, and muscle - contraction under the skin causing hair to stand up to trap heat. All the options are consistent with the described physiological processes.

Answer:

The nervous system and the muscular system work together.
Muscles move rapidly to produce heat within the body.
Muscles underneath the skin contract, causing hair on the skin to stand up.
When hairs on skin stand up, they trap the heat coming out of the body so the heat is kept near the body.
