The basic building blocks of a protein are
a) glucose molecules
b) amino acids
c) hormones
d) fats

The building  blocks of protein are amino acids.

Amino acids are a class of organic compounds that contain at least one amino group, -NH2, and carboxyl group, -COOH.

Alpha amino acids , RCH(NH2)COOH, are the building blocks  from which proteins are constructed.

The NH group of one amino acid and the COOH  group of the other amino acid are joined together and a peptide bond -CONH-  is formed between the two amino acids and the product is called a dipeptide.

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
