Answer:

A suspension is definitely a mixture of two phases.........

Explanation:

A suspension is definitely a mixture of two phases.........and thus a suspension is definitely #"heterogeneous"#. A #"colloid"# does not fall under this umbrella, inasmuch as particle size in your typical colloid, is approx. #(1-5)xx10^-9*m#, whereas particle size in a suspension is approx. #1000xx10^-9*m#.

The practical result? Colloids do not settle out, whereas suspensions do settle out slowly on standing.
