Amoeba: Also ameba. A single-celled (protozoan) organism that constantly changes shape. The word "ameba" is from the Greek "amoibe" meaning "change." Ameba can infect the bowels to cause diarrhea and the liver to cause abscess formation. Here is more information. The definition of an amoeba is a one-celled organism, common in water and soil, possessing no set cell organs, structure, or defining shape. An example of an amoeba is an invisible organism called Entamueba histolytica which is found in tropical areas that are unclean, and causes the deadly disease dysentery. Hope this helps!

The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.
Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.
Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.

When the influenza virus enters an epithelial cell, the infected cell responds by posting antigens and acting as a flag for cytotoxic T cells.
<h3>What is the cell-mediated response?</h3>
The cell-mediated response is a type of immune response where the organism is able to respond to pathogens by immune cells.
Macrophages (as well as other immune cells ) can act during cell-mediated immune responses.
In conclusion, when the influenza virus enters an epithelial cell, the infected cell responds by posting antigens and acting as a flag for cytotoxic T cells.
