4 0

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.

What happens to predator populations when prey populations are scarce? Why?
GenaCL600 [577]
When prey is abundant, predator populations increase because more young are able to survive. More predators kill more prey, which, along with food scarcity, decreases the population. When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other.

Since there are no genes coding for carbohydrates and lipids, how do cells produce them?
lina2011 [118]
<span>Cell code for enzymes that can convert other molecules into carbohydrates, nucleic acids and lipids. Humans can synthesize 11 out of the 20 amino acids and bacteria can synthesize all 20. Plus bacteria can synthesize many of the vitamins that humans cannot, including vitamin C. As far as humans are concerned, we can make carbohydrates and glycogen from glucose. We use some amino acids to make nucleic acids and we can synthesize lipids and cholesterol from acetyl coA. There are certain types of fatty acids we can't synthesize and we must get them from our diet.</span>
