the answer should be DNA REPLICATION
When at the restrictive temperature, we can comfortably expect the cell to stop dividing, whilst continuing to grow
The E2F pathway in a cell is responsible for the transition from the G1 stage of the cell cycle to the S stage. The G1 stage is where a cell grows and expands before the duplication of its DNA.
The S stage stands for synthesis. This is the moment in the cellular cycle in which the DNA of the cell is copied in order to prepare for cellular division.
Therefore, if the transition from G1 to S is blocked by <em><u>temperature restrictions</u></em>, we can expect the cell to continue growing, but <u>not </u>divide.

D = m/V
m = 75g
V = 4 x 4 x 4 = 64 cm^3
d = 75/64 = 1 11/64 g/cm^3
The answer is
Blood picks up carbon dioxide from the cells of the oxygen
