The decomposition of protein molecules into their basic units will yield: deoxyribonucleic acids ribonucleic acids amino acids nitric acids

amino acids

Explanation:

The building blocks of proteins are amino acids. Two amino acids join with each other with a peptide bond and the release of one molecule of water. This is known as condensation reaction. Amino acids join with each other to form peptides. Peptide chains arrange in 3D conformation to form a protein macromolecule.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
