In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).
The correct answer is: Klinefelter syndrome (KS) or XXY syndrome.
This syndrome usually occurs randomly and it may come in different forms:
• When there is an extra X chromosome in each cell
• When there is an extra X chromosome in some cells (mosaic Klinefelter)
• When there is more than one extra X chromosome.
Men with this syndrome often don’t have visible symptoms but can also lead to infertility. On the other hand, some of them have symptoms such as weaker muscles, greater height, less body hair, breast growth…

Answer:
D (Swell and Burst)
Explanation:
Pure water contains a very low concentration of solute materials, hence it is regarded as HYPOTONIC. Since the red blood cell contains intracellular fluid that contains more solutes than the extracellular pure water it is placed in, it is said to be HYPERTONIC in comparison with the pure water.
This difference in concentration between the extracellular solution (pure water) and the intracellular fluid (red blood cell) called CONCENTRATION GRADIENT facilitates the movement of water by OSMOSIS. Osmosis is the process whereby water moves across a semi-permeable membrane from a region of low solute concentration to a high solute concentration.
Based on this osmotic gradient, water moves from the extracellular solution into the cell, causing it to swell and eventually burst as a result of excessive water intake.
