Final answer:
The claim that a peptide bond is reformed by drying or cooling is false; peptide bonds form through a dehydration synthesis reaction, not by drying or cooling.
Step-by-step explanation:
The statement that a peptide bond is reformed by drying or cooling is false. Peptide bonds are covalent chemical bonds that join two amino acid molecules to form peptides or proteins through a dehydration synthesis reaction. When two amino acids align, the carboxyl group of one amino acid reacts with the amino group of the other, releasing a molecule of water and forming a peptide bond. Reformation of a peptide bond would require the components of a broken peptide bond to undergo a dehydration synthesis reaction again, which is a process that does not typically occur simply through drying or cooling.
