Which statement best describes a system that maintains stability and does not produce change?

Which statement best describes a system that maintains stability and does not produce change?

• A. Negative Feedback
• B. Positive Feedback
• C. Output
• D. Throughput

Answer: (A)

Negative feedback keeps a system stable by opposing any deviation from a set point, bringing the state back toward the desired baseline. It dampens changes rather than amplifying them, which is how steady conditions—like body temperature, blood sugar, or other physiological parameters—are maintained. In this sense, the system resists change to preserve homeostasis. That’s why this mechanism best describes a system that maintains stability and does not produce ongoing change. Positive feedback, by contrast, amplifies deviations and pushes the system toward a new state, leading to further change rather than stability. Output and throughput are measures of what a system produces or processes, not mechanisms that maintain stability.
