Answer:
An aneurysm is an excessive localized enlargement of the artery caused by the weakening of the arterial walls. Angioplasty is an incorrect treatment for aneurysm because this would worsen the condition and can lead to death if the aneurysm bursts due to the pressure applied by the widening of the arteries.
Explanation:
Ecology is the study of how living things interact with each other<span> and with </span>their environment<span>. Scientists who </span>study<span> how </span>living things interact with each other<span> and the </span>environment<span> are called ecologists.</span>
Answer:
False
Explanation:
Sometimes the smaller organisms are more fit for the environment because of land shape, predators, etc.
If this is based off opinion, i believe it should be banned, why would you make it easier for criminals? DNA is one of the easiest and most reliable ways to identify a body, what happens when someone away from home passes away and they cant be identified? it could also cause problems for tons of foster children tracking their birth parents. and it'd make it much easier to steal an identity or fake a death, over all it could have a few pros it'd also have many cons. if anyone has an argument id love to hear your thoughts ☺
Answer:
1. Ser and Gln are polar amino acids.
2. The Leu side chain does not form hydrogen bonds with other amino acids.
3. Phe can undergo oxidation to form Tyr.
4. Lysine has one stereocenter (chiral center).
Explanation:
Serine and glutamine are the polar amino acids with uncharged side group. Serine has a "CH2OH" group as its side chain and the presence of hydroxyl group makes it a polar amino acid. Glutamine is one of the amides derived from other amino acids present in proteins.
Leucine is a nonpolar amino acid with an aliphatic side chain and tends to cluster within the proteins to stay away from the surrounding watery medium. Its aliphatic R group does not form any hydrogen bonds to other amino acids.
Phenylalanine is a nonpolar amino acid with an aromatic R group. Oxidation of aromatic R group of phenylalanine converts it into tyrosine which has an additional hydroxyl group in its side chain.
The chiral center is the carbon to which four different functional groups are bonded. The central alpha carbon atom of lysine is bonded to an amino group, carboxyl group, a hydrogen atom, and one positively charged R group which in turn makes it a chiral center.
