Multiple Choice

Carbowax is a blend of liquid polyethylene glycol and wax.

Explanation:
Carbowax is a polyethylene glycol (PEG)–based product crafted as a wax-like blend. PEGs span a range of molecular weights, with lower-weight grades being liquids and higher-weight grades forming waxy solids. In Carbowax formulations, those liquid PEG components are combined with wax to create a meltable, waxy embedding medium that can infiltrate tissue and then solidify for sectioning. That’s why the statement is true: Carbowax is essentially a PEG-based blend that includes liquid PEG and wax. It’s not paraffin, and it’s not simply solid PEG by itself.
