When a raw, shell-less egg was placed in sugar solution, the egg shrank. the egg was brought back to its original size by placing it in water. which process does the experiment demonstrate? a) osmosis b) diffusion c) dehydration d) reverse osmosis

A: osmosis. The egg first expanded because it was placed in a hypertonic solution (sugar water), causing the water to exit the egg to balance the higher concentration of solute outside of the egg. Placing it in fresh water creates a hypotonic environment, thereby causing water to rush back in.

Where are they though?
