<span>The Answer is "R" group.
Amino acids are organic compounds and have two carbon bonds. The three parts of an amino acid are the amino group, the carboxyl group, and the R group. In amino acids, alpha carbon is bonded to hydrogen atom and the other groups. That R group is different in amino acids and shows how the protein monomers are different from each other. </span>
Trees are a crucial part of the<span> carbon cycle</span>, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through <span>photosynthesis </span>in order to make energy. This carbon is then either transferred into oxygen and released into the air by <span>respiration </span>or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.
