Answer:
false
Explanation:
Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive. However organisms need reactive nitrogen to be able to incorporate it into cells.
The cartoon shows Metaphase I.
Metaphase I has homologous chromosomes that line up at the middle while Metaphase II has single chromosomes that line up at the middle.
