The diagram represents waves A, B, C, and traveling in the same medium. Which two waves shown here have the same wavelength?
O A and B
O A and C
O B and C
O C and D

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
