Which best describes dynamic equilibrium?

A
There is a difference in concentration on either side of the cell membrane.
B
There is an uneven distribution of particles inside and outside the cell.
C
Particles are moving into and out of the cell, but their concentrations remain stable.
D
A concentration gradient is forcing water out of the cell and particles into the cell.

9

Which best describes the difference between osmosis and diffusion?

A
Osmosis is the movement of particles from a high to a low particle concentration, while diffusion is the movement of water from a high to a low water concentration.
B
Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.
C
Diffusion is the movement of particles from a low to a high particle concentration, while osmosis is the movement of water from a low to a high water concentration.
D
Osmosis is the movement of particles from a low to a high particle concentration, while diffusion is the movement of water from a low to a high water concentration.
