The surface area to volume ratio of the cell decreases.
This decrease is due to the fact that the volume of the cell increases at a greater rate than the surface surrounding the cell, the cell membrane, increases. This change is also visible when we are blowing up a balloon.
When considering the cell division, the ratio remains roughly the same. It is advantageous for the cell to preserve its surface area to volume ratio, since a higher ratio means that substances are able to diffuse into and out of the cell at a fairly higher rate.
Thymine has a methyl group and is better suited for the storage property of the DNA molecule as it is far more stable compared to Uracil.
RNA contain Uracil instead of thymine so as to make differentiation of RNA molecule from DNA molecules easier.
The clivage furrow forms, the chromosomes are on either side of the cell
If blood typing is not available in an emergency situation, O-Negative blood is universally accepted by all blood types because it is absent of any antibodies. Therefore, if O-Neg blood is on hand in emergency situations, it can be given to anyone.
