Answer:
Platelets help the blood clotting process (or coagulation) by gathering at the site of an injury, sticking to the lining of the injured blood vessel, and forming a platform on which blood coagulation can occur. This results in the formation of a fibrin clot, which covers the wound and prevents blood from leaking out.
Explanation:
Blood is composed of plasma, red blood cells, white blood cells, and platelets. Blood platelets play a role in coagulation (the clotting of blood to stop bleed from an open wound); white blood cells play an important role in the immune system; red blood cells transport oxygen and carbon dioxide.
yeah that's all I can think of
Answer:
This process is called phosphorylation(addition of phosphate) and since the energy comes from photons, this process is termed as photophosphorylation. Yes, the same NADPH donates its hydrogen to combine with CO2 to form glucose (C6H12O6) to become NADP again.
Explanation:
Answer:
Due to absence of erosive agents.
Explanation:
The Maria have few craters compared to the surrounding areas because of no erosive agents such as winds and rain. The erosive agents only formed when there is atmosphere in the region. The atmosphere is responsible for the presence of winds and rainfall. If these erosive agents are present, there will be more craters as compared to the region where no erosive agents are present so that's why Maria have few craters in the region. as compared to the surrounding region.
Similarly, around December 21, the sun is farthest south of the equator.
Around December 21
The sun's most direct rays reach farthest north or south of the equator, around December 21. This is the period of the winter solstice in the Northern Hemisphere, where the Earth is tilted away from the sun. At this time it's summer solstice in the Southern Hemisphere.
