True
All somatic cells have same genes but the genes whose product is not needed are turned off. Some genes are expressed constitutively and some genes are turned off and on depending upon the requirement of proteins.
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
There are man chemical and physical changes such as geno and pheno.
The answer is cell membrane
