Hello! I figured your question was lacking its options so I went online to find them and here they are:
A. Activated platelets release chemicals that inhibit blood clot formation.
B. Activated platelets release signaling molecules that inhibit cell division in damaged tissue.
C. Activated platelets constrict the blood vessels, stopping blood flow.
D. Activated platelets release chemicals that activate more platelets.
Answer:
The correct answer is: D) Activated platelets release chemicals that activate more platelets.
Explanation:
<u>Positive feedback</u><u> is a mechanism in which a stimulus triggers an intensification of this same stimulus.</u>
When a tissue is damaged, the platelets participate in a process called platelet adhesion that consists of contacting and sticking to the collagen fibers of the connective tissue under the damaged endothelial cells. This platelet adhesion <u>activates</u> the platelets and makes them grow projections to contact and interact with one another, while releasing substances to activate other nearby platelets. The accumulation and the attachment of large numbers of platelets ultimately form a <u>platelet plug</u>.
