I believe its called biodiversity
If you don't use them they get stored as glycogen, for later use. buy if you're not active, it can lead to obesity.
Absence of jaws. Is the answer
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.
