Answer:
Bacteria that are helpful in one place may be harmful in another.
What information in the text supports this statement?
A Heliobacter pylori is a bacterium that causes gastritis (irritation or
inflammation of the stomach lining) and peptic ulcers, diseases which were once
thought to be caused by too much acid.
B Streptococcus salivarius appears to help prevent tooth decay in the mouth
but can be dangerous to people with weakened immune systems if it gets
outside the mouth.
Bacillus subtilis releases toxic chemicals to kill fungus, possibly including
Trichophyton interdigitale and other species that cause athlete's foot.
D Skin, which is our interface with the world, supports a large number of the
human body's most diverse populations of bacteria, including Bacillus subtilis.

Answer:
Pyruvic acid is not the end product of fermentation because in fermentation the pyruvic acid is converted into alcohol/lactic acid and carbon dioxide. There are two types of fermentation alcoholic fermentation and lactic acid fermentation.
In alcoholic fermentation, pyruvate is converted into ethanol and CO2 for example in yeast and in lactic acid fermentation pyruvate is converted into lactic acid and CO2 for example in animals muscles.
Therefore in fermentation pyruvic acid is not the end product of fermentation. In fermentation 2 ATP is produced.
The blob operon produces enzymes that convert compound A into compound B. The operon is controlled by regulatory gene S. Normally, the enzymes encoded by the operon are synthesized only in the absence of compound B. If gene S is mutated, the enzymes are synthesized in the both the presence AND absence of compound B. Gene S must encode a(n):
a. inducer.
Bacteria is not as complex as human and other animal lives, which means they need less energy and DNA to evolve in these ways.
