Answer:
In the nitrogen fixation process, nitrogen fixing bacteria converts the N2 in the atmosphere into NH3 (ammonia). This bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil. ... From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification

Explanation:
The frequency increases.
Here's an easy way to think about this. The wavelength is the distance from crest to crest, or trough to trough -- equivalently, it's the distance the wave travels in one period. This means that the speed of the wave is the wavelength divided by the period, or <span><span>v=<span>λT</span></span><span>v=<span>λT</span></span></span> . But the frequency is just the reciprocal of the period, so <span><span>v=λf</span><span>v=λf</span></span>. Clearly, if v increases and the frequency stays the same, the wavelength must increase by an equivalent factor.
<span>DNA replication involves unzipping the DNA molecule, followed by base pairing, which adds complementary nucleotides, to form two new identical DNA molecules that move to the new cells during cell division.</span>
Lipids form the bilayer of cell membrane which act as a partially permeable mmbrane of cell to control the substances moving in and out of the cell.
