When your body temperature rises on a hot day, the neural and hormonal mechanisms activate sweating. Evaporation of sweat leads to cooling of the body surface. This is an example of ________.
A) positive feedback regulation
B) negative feedback regulation
C) chemical cycling
D) emergent properties

Question

This is an example of negative feedback regulation, where a change in a variable (body temperature) triggers a response that counteracts the initial change (sweating and evaporation cooling the body). This helps to maintain homeostasis, or a stable internal environment. Positive feedback regulation would amplify the initial change, which is not the case here. Chemical cycling and emergent properties are not relevant to this scenario.
