What would happen if the glucose concentration within the blood plasma became 1.2%? what direction would water flow (in or out of the cell) and what would happen to the cell shape?

Water would flow out of the cells consequently leading to shrinking of the cells.

Explanation:

If the glucose concentration within the blood plasma became 1.2% then the blood plasma will be hypertonic with respect to the contents of the cells, that is the blood plasma will be highly concentrated compared to the cells. Water would flow out of the cells via osmosis (from their region of high concentration to their region of low of concentration) and thus the cells would shrink.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

the correct answer is 2 and 4
