Active transport requires that the cell move engegy that it has obtained the food to move the molecule threw the cell membrane.The passive transport doesn't required as much energy for the molecule to move....
The answer is b Area A was completely underwater in the past.<span> None of the other conclusions can be drawn; you need more information. You DO know that area A was once completely underwater though.\</span>
<span> Mitosis involves Prophase, Metaphase, Anaphase, and Telophase.
So you have
13 + 12 + 3 + 2 = 30 cells in mitosis
and
90 + 30 = 120 cells in total
Therefore your ratio of cells in mitosis to total cells is 30 / 120 = 1 / 4. That means mitosis should take up roughly 1/4 of the total cell cycle length. Since the completely cycle takes 24 hours, mitosis would then take (1/4)*24 = 6 hours</span>
