Question

30. Which of the following describes homeostasis?

Answer 1

The answer is D. A boy’s heart rate increases when running. Why? First of all homeostasis is all about balance in one’s body. So you can’t immediately cross out answer choices: a, b , and e. Those don’t talk about keeping balance within someone or an organisms body. And you can also immediately eliminate answer choice C because that answer choice is talking about inheritance which coincides with genetics. Lastly the heart rate increase to cool the boy’s body temperature. It’s trying to reach the equilibrium of the body temperature since it’s no longer at balance since he started running. That’s why he starts to sweat (I know that it doesn’t mention that but you should kind of get that since he’s running). Swear cools down your body.
