I think the answer should be B as well hope it helps
The greater the surface area of a cell, the faster the cell can transport materials across its membrane because there is more area to absorb/excrete materials. We also want the surface area much higher than the volume of a cell. the more volume a cell has the slower the transport of diffusion will be. If the cell is smaller because it has a higher surface area than it does volume. Because of this larger SA:V ratio, smaller cells will transport materials faster.
A give the names of each domain 1-3
Denaturing. This step occurs at around 95C. This causes the double strand Helix to spectate
