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>.

Answer:
The answer is the 2nd picture: the coccyx bone in humans.
Explanation:
Vestigial Structure:
Structures or anatomical features that do not currently serve a function is the bodily processes of a living organism. Vestiges are believed to have performed active functions in the organism's ancestors throughout its evolutionary history.
Coccyx Bone:
The coccyx or tailbone is an evolutionary remnant of our tree dwelling ancestors. Coccyx has no use in modern humans as we do not need to climb trees.
The coccyx in modern humans serves as an anchor for muscles.
