which of the following accurately describes the term atom?

• the basic unit of all matter.
• the basic unit of all living things.
• made up of molecules and compounds
• groups of elements bonded together.

Explanation:

First Question (Solvent in Ocean Water Solution)

In a solution, the solvent is the substance that dissolves the solute. Ocean water has salt (solute) dissolved in water. Water is the substance doing the dissolving here. Seaweed, fish pee are not part of the salt - water solution's solvent - solute relationship, and salt is the solute.

An atom is the basic unit of all matter. The basic unit of all living things is the cell. Atoms make up molecules and compounds (not the other way around), and groups of elements bonded together are compounds or molecules, not atoms.

Answer:

A. water
