Hello,
The answer is option A "mitosis".
Reason:
Mitosis one of the stages of a cell where the cells are separated into two chromosomes therefore putting them into a nucleus. Its not option B because cytokinesis is another part and divides one cell into two daughter cells (which means this is involved of the sex of the child). Its also not D because transcription is involved in gene expression.
If you need anymore help feel free to ask me!
Hope this helps!

It is a good idea to create models of how populations are changing so that we are able to take a better look into what is causing it, if it is a bad or good thing that is taking place, how socioeconomic status may be playing an affect on the changes ect. It can also show if there are concerns coming on the horizon by looking at the change and poll shifts.
Channel proteins that form a narrow passageway in gap junctions are known as <span>connexons

These passageways allow the bidirectional passage of iron and signals between the cells. </span>
