Which cell(s) must use ATP energy to move the molecules out of the cell? (Hint: When using energy by the cell molecules will move from Low to High) im not sure if its, both of them or a or b

Cell A

Explanation:

The process in cells that requires energy to transport the molecules from low concentration to high concentration is called active transport. During active transport, molecules move against the concentration gradient, from low to high concentration.

In the given diagram, cell A uses ATP energy to move the molecules out of the cell because the molecule concentration is high outside the side and molecules are moving from inside to outside that is from low to high concentration.

Hence, the correct answer is "Cell A"

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
