- 4. Multiple ChoiceWhen a person smells something, what is actually traveling up their nose?solidsmoleculesmatterplasma
- 5. Multiple ChoiceWhat is the definition of Selective Permeability?The movement of materials across the cell membrane that requires NO ENERGY from the cell.The movement of materials through (or across) the cell membraneThe ability of the cell membrane to allow some things to pass through while preventing other things from passing through.The movement of molecules from an area of high concentration (where the molecules are more crowded together) to a area of low concentration (where molecules are more spread apart)
- 6. Multiple ChoiceOsmosisdiffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentrationthe diffusion of particles from an area of high concentration to an area of low concentrationdiffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentrationthe diffusion of particles from an area of low concentration to an area of high concentration

- 8. Multiple ChoiceOsmosis is the movement of _____ across a membrane.foodenergyoxygenwater
- 9. Multiple Choice_______ regulates what enters and leaves a cell.Cell MembraneNucleusMitochondriaCytoplasm
- 10. Multiple ChoiceEquilibrium?a large amount of substance on side of the cell and a small amount on the other sidea small amount of substance on side of the cell and a large amount on the othersideequal amount of substance on either side of the membraneno particles on either side of the a cell membrane
- 11. Multiple ChoiceWhat is the definition of Osmosis?the movement of WATER molecules across the cell membrane.the state where molecules are equally concentrated (balanced) on both sides of the cell membrane.the process that brings LARGE particles INTO the cell through the cell membranehe movement of molecules across the cell membrane that REQUIRES ENERGY output from the cell
- 12. Multiple ChoiceWhat is the definition of Equilibrium?the process that brings LARGE particles INTO the cell through the cell membraneThe movement of molecules from an area of high concentration (where the molecules are more crowded together) to a area of low concentration (where molecules are more spread apart)the state where molecules are equally concentrated (balanced) on both sides of the cell membrane.the movement of WATER molecules across the cell membrane.
- 13. Multiple ChoiceIn the given scenario what will happen to the organism: salt is poured onto eggplant.Water will move out of the eggplant cells and the cells will shrink.Water will move out of the eggplant cells and the cells will swell.Water will move into the eggplant cells and the cells will swell.
- 14. Multiple ChoiceIn the given scenario what will happen? An egg is placed in pure water for 48 hours.The egg will gain water and swell.Water will move in and out of the cell equally, and the cell with neither shrink nor swell.The egg will lose water and shrink.
- 15. Multiple ChoiceWhich example(s) of cell transport does not require chemical energyDrops of blue food coloring are placed in water and spread throughout the water, turning it blue.A potato slice is placed in water and water molecules from outside the potato move into the potato cells.Both AnswersNeither answers
- 16. Multiple ChoiceThe diagram shows various molecules that move into and out of the cell. How does molecule C move out the cell?Active TransportDiffusionThe use of a protein pumpManipulated osmosis
- 17. Multiple ChoiceAn animal cell placed in a hypertonic (salty) solution willShrinkSwellStay the same
- 18. Multiple ChoiceHow many diamond molecules need to move to reach equilibrium?A net of 2 molecules move inside the cell.A net of 2 molecules move outside the cell.There is no net movement because the molecules are at equilibrium.The molecules do not move.
- 19. Multiple ChoiceWhich way will the water molecules move during osmosis?Out of the cell, so the cell shrinks.Out of the cell, so the cell swells.Into the cell, so the cell shrinks.Into the cell, so the cell swells.
