facell's surface area-to-volume ratio increased from 3:1 to 4:1, what impact would that have on the transport of materials across the cell membrane? A. It would be unchanged B. transport would increase C. transport would decrease D. none of the above​

Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion. Some materials diffuse readily through the membrane, but others require specialized proteins, such as channels and transporters, to carry them into or out of the cell.

Explanation:

Hopefully this helps :)

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
