I don't know the given choices but I found an answer to the above question.
The answer is:
<span>No longer dividing cells of the mammalian brain. Post-mitotic cells will exit the cell cycle and will not contain cells in S phase.
</span>S-phase<span> -</span> part of the cell cycle in which DNA is replicated. Synthesis phase occur between G1 phase<span> and G</span>2 phase<span>.</span>
This is Mitosis, which occurs with all nucleated somatic (body) cells, but not in germ (sex) cells.
Germ cells, aka gametes, on the other hand, undergo Meiosis, a process of nuclear cell division whereby 1 parent cell gives rise to 4 daughter cells. These daughter gametes, either sperm or egg cells, all have 1/2 the number of chromosomes as the original parent, termed "haploid." The genes of these gametes were also randomly assorted and crossed-over, allowing a shuffling of their chromosomes' genes.
The correct option is OSMOSIS THROUGH A SEMI PERMEABLE MEMBRANE.
Osmosis is defined as the process by which molecules of a solvent [water] are transported through a semi permeable membrane from the region of a lower solute concentration to that of higher solute concentration. The membrane is said to be semi permeable because it allows the water molecules to pass through but does not allow the salt molecules to pass.<span />
