Which of the following statements best characterizes positive feedback control of homeostasis?
A
Positive feedback stabilizes the system by counteracting changes.
B
Positive feedback is more common than negative feedback in maintaining homeostasis.
C
Positive feedback amplifies changes and moves the system away from its starting state.
D
Positive feedback is primarily involved in maintaining constant internal conditions.
검증된 단계별 안내1
Understand the concept of homeostasis: Homeostasis is the process by which biological systems maintain stability while adjusting to conditions that are optimal for survival.
Differentiate between positive and negative feedback: Negative feedback mechanisms work to counteract changes, bringing the system back to its set point, while positive feedback mechanisms amplify changes, moving the system further away from its starting state.
Identify examples of positive feedback: Common examples include the process of childbirth, where the release of oxytocin increases contractions, and blood clotting, where the activation of clotting factors accelerates the process.
Analyze the given statements: Evaluate each statement based on your understanding of positive feedback. Positive feedback does not stabilize the system or maintain constant internal conditions; instead, it amplifies changes.
Select the correct characterization: Based on the analysis, the statement 'Positive feedback amplifies changes and moves the system away from its starting state' best characterizes positive feedback control of homeostasis.
