Bacteria are crucial for the production of which gas a) oxygen b) nitrogen c) carbon dioxide

B) nitrogen

Explanation:

There is a group of bacteria called rhizobia, which are important for the promotion of nitrogen gas in our ecosystem, through a process called biological nitrogen fixation.

This fixation is the process by which nitrogen (N2) in the atmosphere is converted into forms that can be used by plants. The reaction is catalyzed by the enzyme nitrogenase, which is found in all fixative bacteria. In terms of agriculture, the symbiosis between nitrogen-fixing bacteria (called rhizobia) and legumes (a family of plants to which soybeans, beans, peas, among others) is the most important.

This allows the nitrogen cycle to continue, in addition to allowing nitrogen to be absorbed by living beings.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
