Question

8/35
negative feedback loops:
amplify processes
are initiated during childbirth
are found only in plants
prevent small changes from getting larger

Explanation:

To determine the correct statement about negative feedback loops:

• "Amplify processes" is incorrect as negative feedback loops dampen or reverse changes, while positive feedback amplifies.
• "Are initiated during childbirth" is incorrect because childbirth involves a positive feedback loop (contractions amplify until birth).
• "Are found only in plants" is incorrect; negative feedback loops are fundamental in all living organisms (e.g., human body temperature regulation, plant water balance).
• "Prevent small changes from getting larger" is correct. Negative feedback loops act to maintain homeostasis by counteracting deviations (e.g., if body temperature rises, mechanisms activate to cool it down, preventing further increase).

Answer:

The correct option is: "prevent small changes from getting larger" (the fourth option in the provided choices).
