By definition, animal cells have no cell wall -- only plant cells do. That being said, the major function of the cell wall in plant cells is to control cell pressure<span> due to …the influx and exit of water into and out of the cell. hope that helped</span>
somatic hypermutation occurs only in the <u>V or Variable</u> regions of rearranged heavy and light chains.
Somatic hypermutation occurs only in activated B cells, not T cells. This occurs in germinal establishments inside of lymph nodes and the spleen, where B cells are stimulated and T cells are present. Somatic hypermutation is a procedure in which point mutations pile up at rates 106-fold greater than the background mutation rates observed in other genes in the antibody V-regions of both the light and heavy chains.
Somatic hypermutation of immunoglobulin (Ig) genes is important in antibody-mediated immunity. SHM in B cells serves as the molecular foundation for antibody affinity maturation. In this way, SHM plays an important role in optimizing antibody-dependent immune responses.

Answer:
A Detritivore
Explanation:
A Detritivore is a heterotrophic organism that feeds on dead plant and animal materials. They could also feed through coprophagy which is nutrition obtained by feeding on feces. Worms that dwell on the soil, insects, and mollusks are examples of detritivores. Detritivores can also be found residing in aquatic environments. Crabs and Lobsters are examples of these organisms.
Detritivores have no teeth. So, they tend to suck in their food, and this food, through peristaltic actions, moves directly into the digestive tract where it is acted upon by digestive enzymes. From the observations, I made about the organism at the mudflat at the ocean, I can conclude that it is a detritivore.
