Answer:
C
Explanation:
Sleet is pellets of ice that form when snow falls into a warm layer and melts into rain. The rain then falls into a freezing layer of air that is deep enough to refreeze the raindrops into pellets

Answer:
C) Release of von Willebrand factor (vWF) from the endothelium, not the epithelium.
Explanation:
Hemostasis is the physiological process of reparation and maintenance of a blood vessel to stop excess loss of blood in case of vascular injury. This process occurs in four stages:
- Vascular Injury i.e. a breach in the endothelial barrier. This results in the dislodge of endothelial cells, exposing the collagen fibers underneath.
- Vascular constriction or vasoconstriction is the constriction of the blood vessels to prevent excessive blood loss.
- Platelet plug formation involves the aggregation and adhesion of platelets to the endothelium.
- Coagulation
Platelet plug formation occurs by the adhesion of circulating platelets to the collagen fibers that have been exposed by dislodging of the endothelial cells. The endothelium, as well as the platelets release a ligand known as the von Willebrand factor (vWF). This molecule acts as a relay or bridge between the integrin receptors on the platelets and the exposed collagen fibers.
Platelets also release chemicals to attract more platelets to the wound site, resulting in more vWF release. This results in more and more platelets adhering to the endothelium, leading to platelet plug formation.
Answer: Coal is a nonrenewable resource.
Based on current data;
- The amount of carbon dioxide put into the atmosphere annually dueto human activities is 840 gigatons
- The amount of carbon in the atmosphere is 10 gigatons
- The amount of carbon stored in fossil fuels is 10,000 gigatons
<h3>What is the carbon cycle?</h3>
The carbon cycle a cycle showing how carbon is recycled between the atmosphere and earth.
The carbon cycle ensures that their is a balance of carbon in the atmosphere as well as on earth.
Human activities have increased the amount of carbon in the atmosphere.
The amount of carbon dioxide human activities put into the atmosphere annually in the present day is 840 gigatons.
The amount of carbon in the atmosphere is 10 gigatons
The amount of carbon stored in fossil fuels is 10,000 gigatons
Therefore, it can be concluded that human activities disrupt the carbon cycle.
