Answer:
B
Explanation:
Amino acids have a basic skeleton as shown in the illustration.An alpha carbon bonded to a carboxyl gorup, amino grpup, hydrogen, and a side chain. However, amino acids differ in their side chains. These side chains can give different amino acids different properties because of their different properties. The side chains give different properties to the amino acid such as size, shape, ionization properties, polarity, charge, acidity, and basicity.
I got D, C, A, B, C, B, D, C.
C (proteins) instead of D (nucleic acids) because if you look at a nucleic acid structure, you'll see that sulfur is not found in it. Sulfur is found in two amino acids (methionine and cysteine), which means it could be found in proteins since amino acids build proteins
