Feedback stimulates your body to respond in the same direction as a stimulus. negative positive

Positive feedback stimulates your body to respond in the same direction as a stimulus.

Explanation:

In the biological system two types of feedback exist, positive and negative. In the positive feedback, as the output increases, the stimulus is enhanced. So, in this case, the output is enhanced highly. In the negative feedback system, as soon as the output reaches to a certain level, the stimulus is inhibited, causing the inhibition of the process of generating output.
