Question

negative feedback loop
in a negative feedback loop, what happens to a variable (like temperature) when it increases past its normal state?

• it decreases until it resumes its normal state.
• it decreases until it is lower than its normal state.
• it does not change.
• it continues to increase.

Explanation:

Negative feedback loops aim to maintain homeostasis. When a variable (e.g., temperature) increases past its normal state, the body initiates mechanisms to counteract this change. The goal is to bring the variable back to its normal state, not to over - correct it to a state lower than normal or to let it continue increasing or remain unchanged.

Answer:

It decreases until it resumes its normal state.
