Explanation:

Positive - feedback mechanisms amplify a physiological process. Blood - clot formation is a positive - feedback as the initial clotting events lead to more clotting. Contractions during childbirth are also positive - feedback, where the release of oxytocin causes more contractions. Maintenance of normal blood pressure and body temperature are negative - feedback mechanisms that work to restore a stable state.
