Answer: C.
Chemoautotrophic bacteria fix atmospheric nitrogen
Explanation:
Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.
Bacteria play a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which convert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
If the activation energy required for a chemical reaction were reduced, the rate would increase so the answer is A.

Answer:
spores have special chemicals that prevent ot from
The conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP) is a key reaction in organisms because it allows for later use of ATP as a source of energy.
False. Although enzymes work as catalyst, they are not carbohydrates, they are proteins.
