1. Identify the three variables in this virtual lab. (Independent, Dependent and Controlled) 2. Was the hypothesis supported? How? 3. What were the possible sources of error? How could you expand this lab for future investigations on this topic?

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
