Cholera is a bacterial infection of the small intestine. vaccination provides protection against cholera. the cholera vaccine is made up of a weakened form of the bacteria that causes cholera. the vaccine will stimulate production and elicit an immune response. if the infection occurs again, the body will produce an even greater attack on the bacteria because of .

The correct answer is memory cells.  

Vaccination refers to the clinical use of immunization established to artificially assist the body in fighting against the disease. A vaccine against an infection is an amended kind of a natural immunogen that may be the component of the pathogen, a toxin, or even the whole pathogen.  

A vaccine does not result in a disease, however, instigates the healthy host to fight against the epitopes of the amended immunogen and produce ample amount of memory cells (T and B cells).  

Due to the production of the memory cells, when the body comes in contact with an antigen or immunogen again, then the memory cells generate antibodies quickly and kills the pathogen before it can impart its influence.  

Immunological memory

Explanation:

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
