Answer:
All this combination of reactions is summarized in that the bacteria reduced nitrate, that is, they added protons to said compound, giving nitrite as a product.
By promoting the appearance of nitrite and that it increases in its concentrations when the zinc dust is thrown away, it becomes reddish since there was a change in pH, that is, the medium was acidified.
Explanation:
Some bacteria take nitrate as a source and end up generating an oxide reduction reaction that gives nitrite as a product, if this reaction advances in a chain, that is, the nitrite is reduced after the nitrate, the product in the future would be ammonia
RNA is a copy of DNA that is used to make proteins. We usually compare all eukaryotic cells as a group to all prokaryotic cells.
A bunch of the same critters. Nah I am just kidding, you will find a lack of resources because if they are all the same animals they will all eat the same thing. I hope this helps you.
