What is diffusion?
Movement of a solute down its concentration gradient, from an area of higher concentration to an area of lower concentration.
Movement of water across a membrane.
The ability of a substance to dissolve in a solvent.
Homeostasis involves the maintenance of a constant internal environment.
True
False
How does osmosis differ from diffusion?
Osmosis involves the movement of solutes, while diffusion involves water.
Osmosis happens only in living organisms.
It has a lower solute concentration outside the cell compared to inside.
It has a higher solute concentration outside the cell, causing cells to shrink.
The solute concentration is equal inside and outside the cell.
Which statement best describes a hypertonic solution?
It has a lower solute concentration outside the cell compared to inside.
It has a higher solute concentration outside the cell, causing cells to shrink.
The solute concentration is equal inside and outside the cell.
It has a lower solute concentration outside the cell compared to inside.
It has a higher solute concentration outside the cell, causing cells to shrink.
The solute concentration is equal inside and outside the cell.
