Question

question:
which of the following is a type of negative feedback?
○ salivating
○ coughing
○ sneezing
○ shivering

Explanation:

Negative feedback in the body aims to maintain homeostasis (stable internal conditions). Shivering occurs when the body is too cold; it generates heat to raise the body temperature back to the set point, reversing the deviation (cold) – this is negative feedback. Salivating, coughing, and sneezing are more related to immediate responses (like clearing irritants or aiding digestion) and are positive feedback or reflexes without the homeostatic correction of negative feedback.

Answer:

D. Shivering
