Respiration is a process of exchanging gas.
B is the only answer that correctly correlates to the question. Heterotrophs are organism that are not able to produce their own source of food. To acquire food, they depend on the organic molecules produced by producers.
Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product.
Answer:
<em>decreases blood flow</em>.
Explanation:
I'll assume the question is about one of the effect of blood flow resistance.
Resistance forces are those forces that opposes the flow of blood through the blood vessels. Resistance forces in the blood vessels changes with the diameter of the blood vessels, and always acts against pressure to move the blood against the blood vessels. If the resistance forces in the blood becomes equal or greater than the blood pressure, there will be no blood flow through the blood vessels. So generally, resistance forces in the blood vessels acts to decrease blood flow through the blood vessels.
