Biology
1 answer:
Zarrin [17]3 years ago
4 0

Answer:

Gravity is considered to be one of the universal forces inherent of nature itself. Gravity is an attractive force between objects, which is proportional to the mass of the objects and inversely proportional to the distance between them. Gravity is what help planets follow an elliptical orbit, and is the reason why we can keep our feet on the surface of the earth.

Refer to the chart of amino acid structures to help answer this question. Which four statements about amino acids are true? Ser
Bad White [126]

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.

Why is adult stem cell research less controversial than embryonic stem cell research?
jok3333 [9.3K]

。☆✼★ ━━━━━━━━━━━━━━  ☾

The correct option would be B. consent can be obtained from adult stem cell donors.

The controversy behind the other option is that it is a form of life, but no consent is taken from the actual life. (i know it's phrased weirdly, my bad)

Have A Nice Day ❤
