Nitrogen fixation is the process by which nitrogen gas from the atmosphere is converted into different compounds that can be used by plants and animals. There are three major ways in which this happens: first, by lightning; second, by industrial methods; finally, by bacteria living in the soil.
<span>Since you left off the choices, I have to just present the facts of what occurs first in the nerve impusle. The first thing that will is happen is the sodium ios will move to the inside of the nueron. The second step is the potassium ions will move to the inside of the neuron. After those move into the nueron, calcium will then move into the nueron. Both the sodium and potassium have 1 postive charge. While the calcium ion has 2 positive charges. </span>
The period of the D string on the violin would be 0.0034 seconds.
<h3>What is the period of a wave?</h3>
The period of a generated wave is the time it takes for the wave's wavelength or successive crests or troughs to pass through a specific point. In other words, it is the time required to complete a full cycle of oscillation.
Mathematically, the period of a wave is given by:
Period = 1/f
where f is the frequency of the wave.
In the case of the D string of the violin in the illustrated problem, the frequency of the wave is given as 293 Hz when it is in tune. Thus, the period can be calculated as:
Period = 1/293
= 0.0034 seconds
Thus, the period of oscillation of wave generated by the D string on the violin with a frequency of 293 Hz is 0.0034 seconds.

Answer:
The pressure is so great at the inner core that it causes atoms to push together.
Explanation:
The oceans cover 71 percent of the Earth's surface and contain 97 percent of the Earth's water. Less than 1 percent of the Earth's water is fresh water, and 2-3 percent is contained in glaciers and ice caps. The oceans contain 99 percent of the living space on the planet.
