_________ _________ are a special type of body cell that can develop into different types of cells.

All of these types of transport require ATP (choose 3)

• Endocytosis

• Exocytosis

• Active transport through protein gates

• Facilitated diffusion

How does the fact that molecules are always moving affect diffusion and equilibrium? (2 correct answers)

• Moving molecules spread out to fill all of the available space evenly.

• Moving molecules mean that molecules become more concentrated as time goes on.

• Moving molecules mean that even at equilibrium some molecules are moving back and forth across the membrane.

• Moving molecules mean that at equilibrium everything is completely still
