Shivering in order to generate heat due to a drop in body temperature is the best example of a negative feedback control mechanism. When the body's temperature drops below a certain set point, shivering is triggered to generate heat and bring the temperature back to its normal level. Once the temperature is restored, the shivering stops, and the feedback loop is completed. This is an example of negative feedback because the response (shivering) is opposite to the initial stimulus (drop in temperature), thus bringing the body back to homeostasis. The other choices, such as increased body temperature due to exercise or increased uterine contractions in labor, do not involve negative feedback loops.
