Vibrio cholerae lives in water and gets the genes to produce a toxin from a virus (phage conversion). The toxin kills the intestinal epithelial cells in the human host resulting in massive diarrhea. Untreated cholera has about a 50% mortality rate. How does killing humans help the bacteria?

because the diarrhea helps the bacteria to spread

Explanation:

Based on the scenario being described within the question it can be said that killing humans helps the bacteria because the diarrhea helps the bacteria to spread. This is because cholera easily spreads in water, killing the intestinal epithelial cells in the human host allows the escrement to become more water, thus allowing the virus to spread more easily.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.

not: both offer magnification to the atomic level.
