Your answer must be a B because it helpful to ask your coach and maybe he could explain you. I hope that is your answer.
Answer:
Platelets are not activated before an injury occurs because that activation is inhibited while they are circulating and there is no damage to the vacular wall.
Explanation:
Platelets are responsible for forming a haemostatic stopper, at the end of the blood coagulation process. These blood components have the ability to go to the place where the vessel wall is damaged and clump together to prevent blood from leaking out.
Platelet migration and activation occurs when the vascular wall endothelium is injured. When this happens, some substances are released - such as adrenaline, ADP and thromboxane A2, among others - and promote platelet activation.
<em>However, this process should not occur before an injury occurs, as it can promote the formation of thrombi that can circulate in the blood vessels and block them.</em>
<u>An inhibitory mechanism, dependent on nitric oxide and prostaglandins, prevents platelets from being activated and clumping in the absence of injury</u>.
I think it’s enzymes I hope that works
Answer:
This is an example of causal reasoning.
Explanation:
It is an example of causal reasoning because the statement is relating two facts as if one would be the cause of the other. In this case, being bald is the cause, and the effect is a heart attack. The flaw in this reasoning is that there is not enough evidence to prove that baldness can increase the risk of heart attacks. That is something that science has to investigate to check that this statement is not a fallacy of false cause.
