Final answer:

Negative feedback loops in biology help maintain balance in biological systems by reversing changes and keeping variables within normal ranges.


Explanation:

Negative feedback is a reaction in which the system responds in such a way as to reverse the direction of change, helping maintain homeostatic equilibrium by reducing an excessive response. For example, body temperature regulation and blood glucose control are processes controlled by negative feedback. In a negative feedback loop, feedback mechanisms work to keep variables within their normal range.
