D

Verified step by step guidance
1
Understand the components of a homeostatic control system. Homeostasis involves maintaining a stable internal environment, and the control system typically includes a receptor, an integrator, and an effector.
Define each component: A receptor detects changes in the environment and sends information to the integrator. The integrator processes this information and determines the appropriate response. The effector carries out the response to restore balance.
Identify the role of hormones in the body. Hormones are chemical messengers that regulate physiological processes but are not a direct component of the homeostatic control system itself.
Compare the list of options with the typical components of a homeostatic control system. Receptor, integrator, and effector are standard components, while hormone is not directly part of this system.
Conclude that the correct answer is 'Hormone,' as it is not a component of the homeostatic control system, but rather a messenger that can influence the system.
