Timmy places a freshwater amoeba on a wet mount slide with freshwater. Timmy examines the amoeba using a compound microscope using high power. What happens to the amoeba body?

Hypertonic setting: the amoeba shrivels up as water in the amoeba moves across it's semi-permeable membrane into the jar of water.

Hypotonic setting: the amoeba swells up as water in the jar moves across the amoeba's semi-permeable membrane into the amoeba's body.

Isotonic setting: nothing happens as the concentration of the freshwater in the jar is equal to the concentration of freshwater in the amoeba's body
