negative feedback positive feedback regulatory feedback stimulation feedback
I gave my students this multiple choice question: When a finger is cut and bleeds, platelets and plasma proteins move to the cut to stop the bleeding. As these move to the cut, this stimulates more platelets and proteins to move to the cut to stop the bleeding. What type of mechanism is being illustrated?

Only one answer is correct among these 4 choices:
- negative feedback
- positive feedback
- regulatory feedback
- stimulation feedback

Could you tell me which one is correct?

positive feedback
