Final answer:
A specific gravity range of around 1.18 to 1.27 enables a fecal flotation solution to effectively separate parasitic material from heavier fecal debris.
Step-by-step explanation:
Specific gravity is a measure of the ratio between the density of a substance and the density of pure water.
In the case of a fecal flotation solution, a specific gravity range of around 1.18 to 1.27 is commonly used to effectively separate parasitic material from heavier fecal debris.
The higher specific gravity of the solution allows the parasitic material to float to the top while the heavier debris sinks to the bottom.
