Question

which is a property of every mixture? one substance dissolves in another substance. the molecules of one substance break down in the other. different samples of a single mixture have different characteristics. one substance can be separated from another through physical means.

Explanation:

A mixture is composed of two or more substances that are physically combined. Physical - separation methods like filtration, evaporation, etc. can be used to separate the components of a mixture because the substances in a mixture retain their own chemical identities and are not chemically bonded to each other. Not all mixtures involve dissolution (e.g., a mixture of sand and pebbles), molecules of substances in a mixture don't necessarily break down in each other, and different samples of a homogeneous mixture have the same characteristics.

Answer:

One substance can be separated from another through physical means.
