Question

Quizplus · Accepted Answer

Based on the fact that the liquid separates into two layers from water, it suggests that the unknown liquid is nonpolar or hydrophobic. Lipids are nonpolar and thus do not mix with water, making them the most likely class of large biological molecules for the unknown liquid.
