Assignment problem: Diffusion is incredibly important for the proper functioning of cells. Our question today is whether or not it is diffusion that is the cause of the commonalities between different cells in their size and shape. You will be measuring the rates of diffusion in cell models that are cut into different shapes and sizes.
Which of the following would be an appropriate hypothesis for this question?
Group of answer choices
a. Diffusion rate is affected by the size of a cell, but not the shape.
b. All of these could be appropriate hypotheses for the experiment presented here.
c. Diffusion rate is affected by the shape of a cell, but not the size.
d. Diffusion rate is affected by both the shape and the size of a cell.
