Answer

Brief Explanations:

The peripheral nervous system helps regulate involuntary body - functions related to homeostasis. Muscle contraction for heat production on a cold day is an involuntary process regulated by the peripheral nervous system. Keratin is produced by skin cells, not muscles. Sweat glands do not break down food. The brain recalling information is a function of the central nervous system, not directly related to the peripheral nervous system maintaining internal environment.

Answer:

Muscles contract rapidly to produce heat on a cold day.
