Question

as bananas ripen they release a gas called ethylene. this gas causes the bananas to ripen faster. as the bananas ripen they release more ethylene, causing them to ripen faster. what is this is an example of? select the correct answer. negative feedback because the cycle continues negative feedback because the cycle stops positive feedback because the cycle continues positive feedback because the cycle stops

Explanation:

1. Recall the definitions: Positive feedback amplifies a process (cycle continues, reinforcing the change), negative feedback counteracts to stabilize (cycle stops or reverses).
2. In the banana ripening example, ripening releases ethylene, which causes more ripening (more ethylene release), so the cycle (ripening → ethylene → more ripening) continues and amplifies the ripening process. This matches positive feedback where the cycle continues.
3. Eliminate other options: Negative feedback would involve stopping/reversing the cycle (so options with "negative feedback" are wrong). The option with "positive feedback because the cycle stops" is incorrect as the cycle continues here.

Answer:

C. positive feedback because the cycle continues
