Peptides bonds are used to join amino acids (monomers) together, forming larger molecules (polymers) ranging in size from small polypeptides to large proteins. Glycogen is a complex carbohydrate formed by dehydration synthesis of glucose molecules. B) Planetary systems would expand and disperse. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core.

Adams seemingly took the result of the poll to mean that 47% of black Americans did not have a favorable view of white people and intimated that he would be changing his approach to racial matters. Electrons are transferred from hydrogen to oxygen during the formation of an ionic bond.
