• A. Control Center, Stimulus, Receptor, Response, Effector
• B. Stimulus, Receptor, Control Center, Effector, Response
• C. Receptor, Stimulus, Effector, Control Center, Response
• D. Effector, Response, Control Center, Receptor, Stimulus

Answer: (B)

Verified step by step guidance

1. Understand the concept of a negative feedback loop: It is a process that helps maintain homeostasis by counteracting changes in a system, bringing it back to a set point.
2. Identify the role of each component: The Stimulus is the change in the environment, the Receptor detects this change, the Control Center processes the information, the Effector acts to counter the change, and the Response is the action taken to restore balance.
3. Determine the sequence: The process begins with the Stimulus, which is detected by the Receptor.
4. Next, the Receptor sends information to the Control Center, which processes the information and determines the appropriate response.
5. Finally, the Control Center signals the Effector to produce a Response that counteracts the initial Stimulus, thus maintaining homeostasis.
