A) The lipids will have formed planar bilayer membranes.
B) The lipids will have formed tiny vesicles filled with water.
C) The lipids will have completely dissolved in the solution because they are partially polar.
D) The lipids and water will have separated into two distinct layers because the lipids are partially nonpolar.
