Which of the following statements about insulin is true? A. Insulin acts as a transport protein, carrying glucose across the cell membrane. B. Insulin facilitates the movement of intracellular glucose transporters to the cell membrane. C. Insulin stimulates the breakdown of stored glycogen into glucose. D. Insulin stimulates the kidneys to reabsorb glucose into the bloodstream. E. Two of the above are true statements.

The correct answer is statement B.

Explanation:

Insulin refers to a hormone that gets discharged from the pancreatic beta cells when the level of glucose within the blood enhances. After that combination of insulin takes place with the tyrosine receptor, which further stimulates the phosphorylation of various substrate proteins present inside the cell. This eventually causes the binding of vesicles comprising facilitative glucose transporters with the membrane of the cell. These transporters combine with the glucose present in the blood and make it move inside the cell.  

To monitor the level of glucose within the blood, insulin causes glucose to move within the cells of the liver, where it gets stored in the form of glycogen.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
