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:
No information can be inferred
Explanation:
Chromosome number provides no reference for establishing any relationship between organisms. The number of chromosome cannot depict whether a living species belong to plant kingdom or animal kingdom. It cannot even depict the evolutionary history of any species. Thus, the organism with lesser chromosome has not necessarily evolved from the species having larger number of chromosome or vice versa.
Chromosome number can only depict the quantity of genetic material with in an organism and hence no relationship can be established living species only on the basis of chromosome number.
I think it's C. Because hibernation is usually for animals living in Continental climates. I basically just eliminated the other answers until I got that one. One example for animals living in cold climates burrowing are Arctic Foxes.
Dams are not associated with economic advantages.
Dams DO associate with changes to waterway ecosystems, siltation behind the dam, and dam maintenance and breajs,
