How do the particles move in simple diffusion?

• From a region of low concentration to a region of high concentration

• From a region of high concentration to a region of low concentration

• From a region of low concentration to a region of low concentration

• From a region of high concentration to a region of high concentration

Diffusion moves down the __________

• concentration gradient

• Avogadro's constant

• conservation of energy

• facilitated function

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

During osmosis

• free water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Result of diffusion where there is continuous movement of particles but no overall change in concentration because the particles stay evenly spread out

• Osmosis

• Diffusion

• Dynamic Equilibrium

• Concentration Gradient

• Hypertonic
• Isotonic

The cell below is in a _____________ solution.

• Hypertonic
• Hypotonic
• Isotonic

A cell in an isotonic solution will

• swell
• shrink
• stay the same size
• impossible to tell

When a cell is placed in a hypertonic solution water

• moves from the inside of the cell to the solution
• moves from the solution to the inside of the cell
• moves equally in and out of the cell
• none of these

Nemo and other ocean dwelling fish cannot survive in freshwater because......

• freshwater is hypertonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypotonic to Nemo's cells and will result in water leaving them causing the cells to shrink

• freshwater is hypertonic to Nemo's cells and will result in water entering them causing the cells to swell and burst

• freshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burst
