While cleaning a saltwater aquarium, students placed a family of fiddler crabs from the saltwater aquarium into a container of distilled water. What effect will this have on the crabs?

B)C)D)

• The crabs will not be affected at all.

• The crabs will excrete excess salts left in their systems.

• The crabs will die if left in the freshwater, their cells will burst.

• The crabs will die if left in the freshwater, their cells will shrink.

Identify which of the following scenarios represents an example of osmosis.

• Blood vessels transport glucose to cells.

• Limp celery becomes crisp in water.

• Sweating lowers body temperature

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. Identify which process does the experiment demonstrate.

• Osmosis

• Diffusion

• Reverse Osmosis

• Dehydration
