A scientific hypothesis is the initial building block in the scientific method. Many describe it as an "educated guess," based on prior knowledge and observation. While this is true, the definition can be expanded. A hypothesis also includes an explanation of why the guess may be correct, according to National Science Teachers Association.
Hope this helps!

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.
Briefly, one can categorize the 3 types of boundaries as so: At convergent boundaries, the two tectonic plates are coming closer to each other; at divergent boundaries they are increasing they move away from each other and at transform boundaries the plates are moving parallel to their boundary. Based on this, all boundaries will be divergent boundaries.
