Mary and Dave have a conversation in class. They conclude that nearly all water pollution takes place in surface water—water on the ground and on top of lakes and ponds. This is pollution they can see. Does your experiment support this claim? Explain your answer.( here's a image of the experiment)

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
