All the following are steps included in linking amino acids to form chains except a. removing the hydroxyl part of the amino group. b. using a peptide bond to connect the amino acids. c. removing a hydrogen from the amino group. d. forming water.

Option D. forming water

Explanation: The combination or linking of amino acids results in the formation of chains called Peptides.

The reaction involved in the formation of peptides is called dehydration or condensation reaction. When two amino acids are linked together, the carboxyl group (COOH) of one of the amino acids and the amino group (NH2) of the second amino acid react together, water (H2O) is given off and a bond or chain is formed called the peptide bond( CO- NH).

answer: they produce more slow than unicellular organisms.
