Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.
