a sphere with a ratio of surface area to volume equal to 0.3 m.
a right circular cylinder with a ratio of surface area to volume equal to
2.1 m)

diffusion test?
o
a. the rate of diffusion would be faster for the right cylinder.
o
b. the rate of diffusion would be faster for the sphere.
o
c. the rate of diffusion would be slower for the right cylinder.
o
d. the rate of diffusion would be the same for the two models.

The correct answer is option A. "The rate of diffusion would be faster for the right cylinder".

Explanation:

The rate of diffusion is defined as the amount of molecules that are exchanged from a body to another. The rate of diffusion is directly proportional to the ratio of surface area to volume , where the higher the ratio of surface area to volume the higher the rate of diffusion. In this case, a sphere have a ratio of surface area to volume equal to 0.3 m, and a right circular cylinder have a ratio of surface area to volume equal to 2.1 m. Since the right cylinder have a higher ratio of surface area to volume, the rate of diffusion would be faster for the right cylinder.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
