Memory B cells are the type of B cells which are formed after the primary infection.
These are important as they help in producing the more intense and accelerated immune response during secondary infection or when the same antigen or infectious agent enters the body.
They do so by producing the polyclonal response, that is, the same epitope is attacked by multiple copies of B cells.

Answer:
A)All organisms are composed of one or more cells.
B)All cells have membrane-bound structures that have certain functions.
D)The cell is the basic unit of organization on organisms.
Explanation:
Created by Mathias Scheiden and Theodor Schwann, Cell Theory involves the assertion that all living beings are formed by cells and that these cells have functional structures, which was possible as a result of the development of microscopy, being, today, a of the most important generalizations in the field of Biology.
In addition, according to cell theory, the cell is the smallest unit of life, and new cells are formed from the division of cells that already exist, and this process occurs from cell division. Another important pillar of this theory is the fact that the cell is the unit of reproduction and transmission of inherited characteristics, that is, all genetic characters transmitted from parents to children, are transmitted from one cell to another in the process of reproduction.
In summary, cell theory states that:
- All organisms are composed of one or more cells.
- All cells have membrane-bound structures that have certain functions.
- The cell is the basic unit of organization on organisms.
Given what we know about the translation process, we can confirm that the RNA in question that aids in the process of translating a short sequence of RNA into an amino acid is mRNA.
mRNA is referred to as messenger RNA. This RNA molecule acts as just that, a messenger carrying the necessary code to create amino acids and therefore, proteins. This messenger binds itself to <em><u>the </u></em><em><u>ribosomes</u></em><em><u> of a </u></em><em><u>cell</u></em>, which are in charge of reading the code,<em><u> one </u></em><em><u>codon </u></em><em><u>at a time,</u></em> and <u>chaining together the corresponding </u><u>amino acids</u><u>. </u>
