Classify each amino acid according to whether its side chain is predominantly protonated or deprotonated at a pH of 7.40. values of amino acid side chains Asp His Lys 3.65 6.00 10.53 РКа Protonated Deprotonated His Asp Lys Answer Banke Now classify each amino acid according to the electrical charge of its side chain at a pH of 7.40. 2 It may help to review the structures of these three amino acids before answering this question. Positive Negative Neutral His Asp Lys

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
