5 0

Answer:

A. It allows plants to use nitrogen to grow.

Explanation:

However, plants can't directly use nitrogen to grow. The bacteria need to convert atmospheric nitrogen ( N2 gas) into a form that plants can use.

Nitrogen fixation is a symbiotic relationship between plants and microorganisms of nitrogen fixers, which in the process of symbiosis perform the binding of nitrogen, which enters the earth from the air (atmosphere).

It is a reduction process of converting the gaseous form of nitrogen from the air into the ammonia form that is available to plants.

Georgia [21]

Answer:

New allele combinations are acted upon by natural selection.
