Diffusion is movement due to ______(Brownian Motion) which "bumps" pushes molecules from
____.
random movement, area of higher conc. to lower concentration
In diffusion when concentrations equalize on either side of membrane,______.
equal movement still occurs
Rates of diffusion are regulated by what?
concentration, size of molecule & density of medium, temperature, convection, distance
Smaller size of molecule will____.
diffuse faster
The higher the concentration the_____.
faster the rate
density of the medium was ___, the denser the medium, the _____.
air, slower the rate
The higher the temp. the _____.
faster the rate
Convection(____)
air movement
The longer the distance the _____.
slower the rate
An____ (potential) may increase or decrease the rate of diffusion and may influence ____.
electrical gradient, equilibrium concentrations
