Answer 14

A stimulus is any condition born as a result of environmental or other factors. Response is how our body tackles it.

For example, suppose you are running very fast, this results in heavy muscular activity and muscle cells start burning calories which in turn require increased amount of oxygen supply. This is a stimulus, body is now facing reduced supply of oxygen and now it has to do something in order to sustain. Correct?
