How does protein denaturation happen? [ Ans: ] the protein is
subject to changes in temperature, pH, exposure to chemicals,
and structure may change.
What is a solute? [ Ans: ] the substance that is dissolved (salt)
What is a solvent? [ Ans: ] the substance in which the solute
dissolves (water)
What is the monomer unit of nucleic acid? [ Ans: ] nucleotides
