Answer 1

Feedback mechanisms in biology are essential for maintaining homeostasis with negative feedback loops returning a system to a set point and positive feedback loops amplifying changes.

Step-by-step explanation:

In biology, feedback mechanisms are critical for maintaining a stable internal environment, or homeostasis. Specifically, negative feedback loops work to counteract changes in the system, bringing it back to a set point, whereas positive feedback loops amplify changes leading to a more extreme effect. For example, temperature regulation in humans involves negative feedback; when body temperature rises, mechanisms are activated to cool it down, and vice versa. On the other hand, blood clotting is an example of a positive feedback loop, where the presence of clotting factors attracts more platelets, leading to rapid clot formation.
