Answer:
Oxygen
Explanation:
The formula for cellular respiration is oxygen + glucose -> water, carbon dioxide, energy. You can already cross out A and D because they aren't in the formula, so you have two left, water and oxygen. The reason why it is oxygen and not water is because without oxygen you can't even have water. also, I just got this right on my test :-)

Nonvirulent bacteria can still be transformed into virulent bacteria if it is combined with debris from heat-killed virulent bacteria that is first treated with RNase, protease, or no enzyme because these are important factors for the establishment of virulence and are often required when bacteria modify their genetic record in response to the conflicting or adverse situations.
