Question

You are studying the relative size and numbers of living organisms. In your study you recall relationships between cell size and volume and use that to consider observations of nature to determine if a relationship between these two parameters exists. Studies that would provide useful insight into your question of cell size and volume would include a comparison of

Check All That Apply

A: nematodes with a greater surface area than circular organisms of the same mass.nematodes with a greater surface area than circular organisms of the same mass.

B: spherical cells with less surface area than nerve cells or cells with microvilli.spherical cells with less surface area than nerve cells or cells with microvilli.

C: big cells with larger surface area-to-volume ratios than little cells with smaller surface area-to-volume ratios. big cells with larger surface area-to-volume ratios than little cells with smaller surface area-to-volume ratios.

D: increased internal surface area in organisms that subdivide organismal function into specific tasks using organs like lungs and stomachs as opposed to organisms of the same size with no subdivisions or organs. increased internal surface area in organisms that subdivide organismal function into specific tasks using organs like lungs and stomachs as opposed to organisms of the same size with no subdivisions or organs.

E: lung cell research that shows decreased surface area provides faster and more efficient oxygen and carbon dioxide transfer across membranes.lung cell research that shows decreased surface area provides faster and more efficient oxygen and carbon dioxide transfer across membranes.
