negative - feedback control systems:
○ oppose a change.
○ accelerate a change.

○ establish a new set point.

Explanation:

Question 10

In a feedback control loop (e.g., in physiological homeostasis), the basic components are sensor (detects change), integrating center (processes info), effector mechanism (acts to correct), and the controlled variable. A transmitter is not a standard component of a feedback control loop.

Homeostasis is maintaining internal stability. Circulatory (transports nutrients, gases), Endocrine (hormonal regulation), Lymphatic (immune, fluid balance) are highly involved. Reproductive system’s main role is reproduction, not direct homeostasis maintenance.

Negative - feedback control systems work to oppose a change and bring the variable back to the set point (e.g., body temperature regulation). Positive feedback accelerates change; negative feedback doesn't establish new set points or have no effect.

Answer:

B. Transmitter
