Answer:
Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.
Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.
Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.
S phase, g0, g2, g1, metaphase and prophase
Is composed of G1 phase<span> (</span>cell<span> growth), followed by S </span>phase<span> (DNA synthesis), followed by G2 </span>phase<span> (</span>cell<span> growth). At the end of interphase comes the mitotic </span>phase<span>, which is made up of mitosis and cytokinesis and leads to the formation of two daughter </span>cells<span>.

Answer:
Ralph's radial nerve may be getting compressed
Explanation:
Based on the information provided within the question it seems that Ralph's radial nerve may be getting compressed. This nerve, which is located in the armpit region, if compressed can cause temporary cessation of nervous transmission which is what causes numbness (as Ralph is feeling). If this compression continues for too long it can also cause permanent nerve damage.
