Which of the following are typically required to maintain a stable internal environment?

A. Decreased atmospheric pressure.
B. Negative feedback mechanisms.
C. Positive feedback mechanisms.
D. An unstable outside environment.



Answer :

Final answer:

Homeostasis is maintained by negative feedback mechanisms to regulate internal conditions.


Explanation:

Homeostasis is the ability of living things to maintain a stable internal environment. This is achieved through negative feedback mechanisms, which help regulate conditions such as body temperature, blood sugar levels, and pH within a narrow range. The process involves components like receptors, control centers, and effectors working together to keep the internal environment steady.
