During mitosis, chromosomes move to the middle of the spindle during metaphase. Mitosis is a type of cell division in which the parent cell divides into two daughter cells with each daughter cell receiving the same number of chromosomes as the parent cell. Mitosis has the following phases: prophase, metaphase, anaphase and telophase.
During the process of polymerization, monomers combine by sharing electrons. This process forms a polymer, which is made of repeating subunits. The resulting material is used in a variety of ways.
<span>Fungi are not producers. A producer "produces it's own food" or more specifically, it creates organic molecules from inorganic molecules using a nonliving energy source. </span>Fungi are consumers<span> because they "consume another organism for food" or more specifically they steal organic molecules from other living things. </span>
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.
