Four models describe control of body temperature. Which model is consistent with homeostasis?
A temperature change is detected, information is processed, and effectors oppose the change.
A temperature change activates effectors, which increase the change until receptors switch off.
A temperature change is processed by receptors, while the brain acts only as an effector.
A temperature change alters the optimum, so the body no longer needs a corrective response.
