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>.
Decomposers are like the housekeepers of an ecosystem. Without them, dead plants and animals would keep piling up with the nutrients the soil needs trapped inside. Decomposers clean up the dead material by processing it and returning the nutrients to the soil for producers.

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.
