Translocations may be balanced when there is an even exchange of material with no genetic information extra or missing, and ideally full functionality. Or can be unbalanced where the exchange of chromosome material is unequal resulting in extra or missing genes. For example a child who has an unbalanced translocation may have learning disabilities, developmental delay and health problems. The seriousness of the disability depends on exactly which parts of which chromosomes are involved and how much missing or extra chromosome material present.
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…

Explanation:
An optimal temperature graph plots the rate of the enzyme reaction against the temperature. We know that the optimal temperature of this enzyme is 37C, so we know that at this temperature, the rate will be highest.
Additionally, there will be a minimum temperature required for the enzyme to work at all, which is why the line graph slowly increases the rate until its optimum at 37C.
Finally, at higher temperatures, the enzyme will become denatured and its activity will be diminished. This is why the activity drops at high temperatures and is non-existent at very high temperatures.

Because they reminded him of the bare wall rooms where monks lived. These rooms were called cells.
