3. What is the solution to the problems of cell growth ?
: the solution to the problem is for the cell to split in half.

4. As a cell increases in size, which increases more rapidly, its surface area or its volume ?
: i think both would be increasing at the same rate.

5: Caculate the surface area, volume, and ratio of surface area to volume of an imaginary cubic cell with a lengh of 4 cm.
: surface area = 96
:volume = 64 cm2
:ratio of surface area to volume = 3/2
