The answer is: B; the diffusion gradient in cell B is steeper
Cell B actively converting oxygen to water in cellular respiration, therefore the oxygen concentration would be much less when compared to oxygen concentration of cell A.
Diffusion will allow molecule to move from container with higher concentration to container with lower concentration. The difference in concentration will increase the speed, so the speed of oxygen diffusion to cell B would be faster.

Answer: e. prokaryotic cells lack nuclei.
Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.
