Beth learned in her science class that white blood cells in the human body capture harmful material by engulfing them. Then they digest them using enzymes, thus protecting the body from infection. Which eukaryote has a similar mode of nutrition?

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
