Explanation:
Meiosis is known to be a process of reducing the number of chromosomes in a diploid to half.
And it should be noted that , meiosis requires the pairing of two chromosomes sets.
Therefore in this case, before meiosis can occur in the haploid, it must involves two haploids. This means that two individual haploid will fuse together to form diploid meiocyte, which will allow meiosis to occur.
This is the reason why meiosis can only takes place on haploid species.
In summary, it should be noted that, meiosis can only takes place in a diploid and two individuals haploid [ haploid species] that can fuse together to form diploid, but not in a haploid individual.
Answer:
B) Viruses are killing some of his B cells and becoming incorporated into the genomes of others.
Explanation:
Epstein-Barr virus causes infectious mononucleosis by following mechanism.
1) Epstein-Barr virus attaches to and infects epithelium of the throat where it replicates and causes pharyngitis.
2) Virions enter the lymphoid vessels and are carried to the lymph nodes. Some virions escape the lymphnode trap and are carried to the bloodstream.
3) Virions attach specifically to B lymphocytes and infect them, producing either latent infection or productive infection.
4)The infected B lymphocytes actively replicate and differentiate into cells producing random immunoglobulins.
5)T cells respond to infection and destroy the lymphocytes replicating EBV vitus.
6) Latently infected B lymphocytes become immortal. They are not attacked by T cells.

Because of symptoms and age, we would consider some diagnosis of bronchitis due to RSV infection, pneumonia because of Haemophilus influenza infections, and pertussis infection including apnea. Here I can say the answer is pneumonia due to infection of Haemophilus influenza.
The kind of treatment we can give depending on my diagnosis are; high dosage of oral erythromycin to clear the infection bacteria, supportive therapies in hospital in order to maintain blood oxygen levels and in open airways, low dosage of erythromycin which is given intravenously to clear the infection of bacteria which I can say it is the best treatment.
Some of the treatment for the infant to diminish such infection chances are MMR vaccines, toxin antiserum DTaP vaccine, influenza shot which I can recommend for the infant.
The best reason I can say about these conditions and symptoms are associated with pneumonia whereby we can say the low dose of erythromycin which is given intravenously is effective. The best prophylactic treatment is influenza shots.
