Answer 1

Answer:

B) 3 amino acids joined by 2 peptide bonds

Explanation:

The general formula of amino acids:

R-CH(NH2)-COOH

It can be seen clearly in the attached image that there are three amino acid molecules.

Now the three molecules of amino acids are joined by 2 peptide bonds.

Peptide bond:  a bond formed between first carbon of one amino acid and nitrogen of another amino acid releasing a water molecule( H2O).
