Carnoy solution does not preserve fat well.

Explanation:
The effect of fixatives on lipids is what's being tested. Carnoy solution is a rapid fixative made of ethanol, chloroform, and acetic acid, and the chloroform component acts as a solvent for fats. This causes fats to be dissolved and removed from tissue rather than preserved, so fats are not well preserved by this fixative. Therefore, the statement is true. If you needed to preserve fats, you'd use a different fixative, such as osmium tetroxide.
