blended evenly throughout.

Also known as a solution. A solution is a homogeneous mixture of particles so small that they cannot be seen with a microscope

and would never settle.

Homogeneous Mixtures

A type of mixture with particles that are larger than those in solutions but

not heavy enough to settle to the bottom of the container.
