Answer:
An important feature that B-cells must have in order to become plasma cells and synthesize antibodies is increased rough endoplasmic reticulum in order to have the surface area needed for antibody production (option A).
Explanation:
The transformation of B cells into plasma cells to produce antibodies is a well known function of lymphocytes related to the immune response. This leads to a series of structural transformations in order to performs their function.
The rough endoplasmic reticulum (RER) has the function of contributing to protein synthesis, in conjunction with the ribosomes that are attached to it and the information of the mRNA.
<em>One of the changes experienced by B cells in their transition to plasma cells is the availability of larger RERs, in preparation for antibody synthesis, formed mostly by proteins</em>.

Answer:
1. Klinefelter syndrome
2. Nobody can be born with a single X chromosome
Explanation:
1. A genetic condition in which a male is born with an extra copy of the X chromosome
Klinefelter's syndrome isn't inherited, but rather occurs only as a result of a random genetic error after conception.
Males born with Klinefelter's syndrome may have low testosterone and reduced muscle mass, facial hair and body hair. Most males with this condition produce little or no sperm,
2. Sex chromosome occurs due to combination of the X and Y chromosome of both parents.
Although the DNA packaging with histones proteins is mean to form nucleosomes (groups of 8 histones proteins), the higher structures why the genetic material is packaged with those molecules is to form chromosomes, as you said.
C; to stop pathogens with light harming the host cell
