The three chromosomal aberration:
1.) Inversion - breakage of chromosome in two places , the other piece of DNA is re- inserted into the chromosome.
2.) Translocation - the one piece breaks off and attaches to another chromosome.
3.) Deletion - the loss of segment of chromosome.

Each (both large and small) colony is carefully counted (using magnifying colony counter if needed). Each colony represents a “colony-forming unit” (CFU). For accurate counts, the optimum count should be within the range of 30-300 colonies/plate. To insure a countable plate a series of dilutions should be plated.
I am not sure but does it not already do that. Because i think it goes both ways so we can get sun <span />
Answer:
The bacterium Vibrio cholerae is the primary cause of cholera disease that mainly infects the small intestine and primarily leads to the dehydration of the body.
Explanation:
The genetic analysis reveals that the aforementioned causative bacteria surpass the acidic conditions of the stomach and eventually reaches the intestinal wall and attaches to it. This is followed by the production of toxic protein by the bacterium. This protein is taken inside the cell via receptor mediated endocytosis followed by its binding to the host protein Arf6. This binding leads to the production of cAMP that results in the dehydration process. This mechanism leads to excessive accumulation of chloride ion in the intestine preventing the entry of sodium ion.
These two ions are associated with the creation of water-salt environment in the intestine that leads to tremendous diarrhea via the process of osmosis.
Hence, we can say that cholera bacterium affects the individuals at the cellular level and osmosis plays a vital role in the process.
