Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.
Explanation:
<u>The emulsion test for fats</u> is a test used to show the presence of these in some substances or foods.
Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.
This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.

The complete question is :
The success of plants extending their range northward following glacial retreat is best determined by _____.
A) whether there is simultaneous migration of herbivores
B) their tolerance to shade
C) their seed dispersal rate
D) their size
Answer: The seed dispersal rate
Explanation:
The seed dispersal can be defined as the movement of the seeds away from the parent plant. The ability of the plant to extend is completely dependent on the ability of the plant to disperse its seeds.
Plants have very limited ability, they need vectors to carry its seed from one place to another.
The biotic and abiotic vector both are involved in carrying the seeds which helps in expansion of the trees.
