As a cell grows, the surface area to volume (SA:V) decreases and the cell must divide or die. The decreased SA:V ratio decreases would affect all BUT
A) osmosis into and out of the cell.
B) the efficiency of signaling proteins.
C) the number of stages involved in cell division.
D) the functioning of the cytoskeleton transport system.

The total whole exterior area of an object that it occupies is called the surface area. While the scalar quantity that the object occupies is called volume.

The decreased SA : V ratio will affect all except:

Option C. The number of stages involved in cell division.

This can be explained as:

Due to decreased surface area to volume ratio, the size of the cell increases and affects the absorption and release of substances in and out of the cells and hence affecting the osmosis.

The cells signalling will also be affected as the increased cell size will affect the molecule to delay.

The cytoskeleton transport system will be delayed due to decreased SA : V ratio.

Therefore, SA : V ratio does not concern the cell division stages.
