Energy carried by waves

Explanation: light, heat and radio are carried by a variety of waves in the ELECTROMAGNETIC SPECTRUM.

a molecule, containing a very large number of atoms, such as, protein, nucleic acid, or synthetic polyme.

Explanation:

A macromolecule is a very large molecule, such as protein, mostly commonly composed of the polymerization of smaller subunits, called monomers. They are typically composed of thousands of atoms, or more. A substance that is composed of monomers is called a polymer.

Easier version to understand: Macromolecules are large, complex molecules.
