In order to increase the rate of diffusion of materials in and out of the cell, the following modification can be done to the cell:
1. the shape of the cell can be changed to one that has high surface area to volume ration, for example sphere.
2.The cell can also divide into two in order to increase the surface area to volume ratio.
<span>C. controls which substances enter and exit the cell
Good Luck!!</span>
<span>Bacterial genome is prone to mutational changes due to its simple nature and less efficient DNA repair mechanisms compared to humans, thus it has more chances of obtaining new genetic traits.</span>
The control group is the part of an experiment that does not receive the variable and is used for comparison.
