Correct Answer
a complex solution and a heterogeneous colloid
Explanation
The interior of a living cell is made up of both a complex solution and a heterogeneous colloid. The cytoplasm contains water with dissolved salts and organic molecules (a solution), but also large protein molecules and other structures suspended in that medium (a colloid). A colloid is a mixture in which particles are dispersed but not dissolved.
