Question

this graph shows an example of... positive feedback blood sugar regulation homeostasis negative feedback

Explanation:

The graph shows body temperature regulation: when temperature rises, effectors (like sweating) bring it down; when it drops, effectors (like shivering) raise it. This is negative feedback, where the response opposes the change to maintain stability (homeostasis). Positive feedback amplifies changes, blood sugar regulation is a specific case, but the graph’s temperature regulation via opposing responses fits negative feedback.

Answer:

D. Negative feedback
