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.
<h2>Answer </h2>
Neutral Variation
<u>Explanation</u>
Point mutations in noncoding regions of DNA result in neutral variation. The alleles which neither considerably sum to nor exceedingly lower from body consistency. It is the accumulation of such alleles located within a community that can be explained as expressing neutral variation. Neutral Variation implies in various alleles that are existing at an assigned genetic locus because those alleles are not distinct by natural selection.
