<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:
The genetic variations that are best suited for their enviornment
Explanation:
Those that are not well suited for their environment will die off, leaving only the ones that are suited for it. This species will slowly take hold until the species has adapted and become a completely different one.
Answer:
The molecules in a solid are more closely packed than those in a gas. Gas molecules are VERY spread apart, which is why we cannot see them.
Explanation:
Answer:
__Rigor mortis__________ is caused by the lack of adenosine triphosphate (ATP) to the muscles
Explanation:
The rigor mortis corresponds to the stiffness of the muscles (they cannot contract or elongate) due to the lack of ATP, where I fixed the bridges between actin and myosin. This event happens when the oxygen transporting organs stop working.
In this case, c) mimicry is the answer. In Batesian mimicry in which harmless animals mimic toxic animals. In this case, I assume the milk snake is harmless and the coral snake is venomous. Since the milk snake has a trait similar to deadly coral snake, less animals would eat it thinking it is dangerous. Over time all the milk snake that look like the deadly coral snake would survive leading to evolution by natural selection. This would lead to more and more milk snake mimicking the resemblance of the deadly coral snake.
a) The deadly coral snake has a warning color adaptive radiation. If the question had described the environment and how the snaked adapted to the environment via warning coloration. This would've been correct.
b) cryptic coloration is more about camouflage with the environment. If the question had state how a certain feature help one of the animals blend into the background. This would've been correct.
d) I'm not sure whats different between this and a so i'll consider them both the same.
