SOLVED QUESTIONS GRADED A+

● diffusion. Answer: movement of molecules from an area of higher
concentration to an area of lower concentration.


● concentration gradient. Answer: the difference in the concentration of
molecules across a distance.


● equilibrium. Answer: the concentration of molecules will be the same
throughout the space the molecules occupy.


● osmosis. Answer: the process by which water molecules diffuse
across a cell membrane from an area of higher concentration to a area of
lower concentration.


● hypotonic. Answer: describes a solution whose solute concentration is
lower than the solute concentration inside the cell.


● hypertonic. Answer: describes a solution whose solute concentration
is higher than the solute concentration inside the cell.
