Answer:

A familiar example of homeostatic regulation in a mechanical system is the action of a thermostat, a machine that regulates room temperature.

Explanation:

Answer:

Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

Explanation:

HELPPPPPPP!! To maintain homeostasis, the human body has many systems that remove wastes from the body. Which correctly explains how two organ systems interact to eliminate wastes?

A.
The muscular system helps the bladder to release urine from the excretory system to maintain homeostasis.

B.
The muscular system helps push carbon dioxide wastes from the respiratory system to maintain homeostasis.

C.
The muscular system helps squeeze solid wastes from the digestive system to maintain homeostasis.
