Answer:a positive feedback

Explanation: positive feedback is a type of feedback mechanism employed by the body,in which an output is enhanced or acclerated.

In contrast to negative feedback where the body regulates it's internal conditions by reducing the effect of a stimuli,In positive feedback ,the body enhances the effect of the stimuli.
