Answer 1

1a. They are the same just operating in a different context

The basic chemistry of all the molecules is the same. The difference lies in their arrangement and function inside the body or outside the body.

2d. Atom, macromolecule, tissue, organ

For example, carbon, DNA, nucleus, cell, tissue may be muscular tissue, heart

3c. The study of compounds containing carbon and hydrogen and their derivatives.

Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen.

4a. ammonia
