Gastrointestinal epithelial cells. The epithelial cells that
like the gastrointestinal tract are typically HIGHLY PROLIFERATIVE. Cells that
line gastrointestinal tract. Cells proliferate and produce plasma cells. The
plasma cells bear antibodies with the identical antigen specificity as the
antigen receptors of the activated B cells.
Answer:
The Gram-negative diplococci <u>Neisseria </u>are pathogenic microbes that infect mammalian mucous membranes, and include the species which causes gonorrhea.
Explanation:
Options for this question are:
- <em>Streptococcus
.</em>
- <em>Coxiella
.</em>
- <em>Neisseria
.</em>
- <em>Listeria
.</em>
- <em>Haemophilus.</em>
Bacteria of the genus Neisseria are Gram-negative, with a rounded morphology that are associated in pairs, so they are called diplococci. They are aerobic microorganisms, no more than 1 micrometer in diameter, immobile and not sporulated.
Their biological importance is due to the fact that they cause diseases in humans, such as bacterial meningitis -caused by N. meningitidis- or gonorrhea, associated with N. gonorrhoeae.

A mutation is a rare, accidental or induced modification of genetic information (DNA or RNA sequence) in the genome.
The consequences of a mutation vary according to the part of the genome affected. A mutation is said to be hereditary if the mutated genetic sequence is passed on to the next generation.
In multicellular animals, germline mutations can be transmitted to offspring, whereas somatic mutations do.
Somatic mutations do not affect cells intended for reproduction, so they are never hereditary:
* Post-zygotic mutations are the mutations that appear in the egg after fertilization. They are rarer and are expressed as mosaic in the individual concerned (the mutation will be present only in the daughter cells originating from the mutated embryonic cell).
* Mutations can appear throughout life on the DNA of any cell; they are then transmitted to the line of the daughter cells. These can, in some cases, become tumor cells and then form cancer.
