<span>R group (or side chain) is an organic component of amino acids that is unique to each amino acid. </span> <span>Three of the amino acids have basic side chains at neutral pH: arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base and their pKa's are high enough that they tend to bind protons, (positive charge). Aspartic acid or aspartate (Asp) and glutamic acid or glutamate (Glu) are acidic amino acids because their side chains have carboxylic acid groups whose pKa's are low enough to lose protons, (negatively charged). The non-polar amino acids contain uncharged functional groups<span> at physiological pH and are incapable of participating in hydrogen bonding. </span></span>

Answer:
Earth has been our place for many years. all inhabitants on earth are causing great destruction. along the way we tried to resolve issues yet some we couldn't figure out. the one we couldn't figure out had made a great impact on our world today. Just how do we stop it? Many ways actually, taking pollution for example. pollution is a great cause for why earth isn't as lively as before. along the years we've polluted 92% of the earths air. causing us to breathe unhealthy air. We can easily fix this problem with finding new ways to get somewhere like riding a bike or taking an energy efficient car. Therefore, we humans have change the world dramatically by doing good things and bad things, too. but in the end we are the ones causing earth to nearly give up, so we can also be the ones to let the earth forgive.
hope this helps you out!

Answer:
The correct answer would be elongation.
Cell elongation is defined as the lengthening of a cell during differentiation of a cell. It takes place during growth of an organism or during movement in mature plants.
In plants, it is primarily regulated by light and plant hormones like auxin.
Auxin modifies the structure of the cell wall which helps the cell to elongate.
