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.

3) store hereditary information
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, as on units called chromosomes. ATP functions as a precursor molecule for more complex nucleotides.
Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

We can confirm that codons help determine the function of the protein they are coding because they control the order of the amino acids that will form the protein.
<h3>What is an amino acid?</h3>
Amino acids are organic compounds that serve as the base for all proteins. Codons code for amino acids and therefore control the order of the amino acids that will form the protein. This order will dictate the function of the protein.
Therefore, we can confirm that codons help determine the function of the protein they are coding because they control the order of the amino acids that will form the protein.

By there DNA. When when x and y have sex they send there gene into the offspring
Answer:
no2
Explanation:
beacuse when people number growth too much it can have impact by economic and etc and many people are hunting animals for food and for other thing so we have to balance it
