Answer

Brief Explanations:

  1. Heterogeneous mixtures have components that separate over time (settle out) due to differences in density etc.
  2. The proportions of solute - to - solvent can vary in a heterogeneous mixture as it is not uniform.
  3. In a heterogeneous mixture, the solute is not evenly distributed; this is a characteristic of homogeneous mixtures.
  4. Heterogeneous mixtures are not necessarily composed of two solvents and two solutes; they can have various combinations and numbers of components.
