A. Which form of nitrogen in the soil is NOT usable by organisms? b. Why is this form not usable? Be specific.

c. How can this form be made usable to organisms?

A)Fixation. Nitrogen in its gaseous form (N2) can't be used by most living things

B) it can not be used because it most be converted or, ’fixed’  to a more useable form. To do this it goes through a process called fixation.fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains.

C) This form can be made more usable if it’s converted. It has to go through the process of fixation so the gene pool changes.

Explanation:

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
