Explanation:

a. Although viruses can survive outside a host on household surfaces, their ability to duplicate themselves is compromised-shortening the virus's life span. Humidity also makes a difference; no bacteria or virus can live on dry surfaces with a humidity of less than 10 percent.

b. Bacteria are among the fastest reproducing organisms in the world, doubling every 4 to 20 minutes. Some fast-growing bacteria such as pathogenic strains of E. ... coli bacteria under specific conditions.

c. Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeas

Some bacterial toxins, such as Botulinum neurotoxins, are the most potent natural toxins known.
