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>.
Explanation: This is because the reactants of the chemical reaction<span>(the chemicals that are mixed together are the reacting chemicals or reactants) are at its high in concentration at the start of the </span>reaction<span>. These reactants are constantly </span>being <span>used to make products.</span>
Answer:
the answer for your question is 3 and 4
A new born has soft spot on he top of its head. This is called as fontanelle and is diamond in shape present on the top of the head of the baby.
Babies skull is very soft and can be very easily moulded, to help them squeeze through the birth canal at the time of delivery.
Moulding is done in the skull of the babies as it is most largest part of the body during the time of delivery.
As soon as the skull and bones of the baby meet and fuse they become hard gradually.
Large gas giants that vary being VERY cold or VERY hot 2 have rings noticable but saturns are the most significant
