Question

"The process where ethylene gas is known to cause fruit to ripen, and as the fruit ripens, it produces elevated amounts of ethylene, is an example of which of the following feedback mechanisms?

A) Positive feedback.
B) Negative feedback.
C) Homeostasis.
D) Endocrine regulation.

Please select the most appropriate option to describe this feedback mechanism."

Answer 1

The process where ethylene gas causes fruit to ripen and produces elevated amounts of ethylene is an example of positive feedback.

Step-by-step explanation:

The process where ethylene gas is known to cause fruit to ripen, and as the fruit ripens, it produces elevated amounts of ethylene, is an example of positive feedback.

Positive feedback is a type of feedback mechanism where an initial change or stimulus is amplified, leading to further changes in the same direction. In the case of fruit ripening, the ethylene gas released by the ripening fruit stimulates the production of more ethylene, which in turn accelerates the ripening process in other fruit.

For example, when a banana starts to ripen and release ethylene, the ethylene triggers the production of more ethylene, causing nearby bananas to ripen as well.
