• are a product of endosymbiosis

An organelle involved in breaking down lipids, proteins, carbohydrates, damage organelles, and bacteria are ___

• Golgi Appaparatus

• Vesicles

• Vacule

• Lysosomes

In diffusion

• water moves from a high concentration to a low concentration

• water moves from a low concentration to a high concentration

• molecules move from a high concentration to a low concentration

• molecules move from a low concentration to a high concentration

A hypertonic solution is one where

• the concentration of a solution outside the cell is higher than the concentration than inside the cell

• the concentration of a solution outside the cell is lower than the concentration than inside the cell

• the concentration of a solution outside the cell is equal to the concentration than inside the cell

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
