diffusion
active transport
How long does diffusion last?
Until the concentration of particles in the system is equal
Until a region in the system has a smaller concentration of particles than the other
Until a region in the system has a greater concentration of particles than the other
Until the particles disappear from the system
What is Isotonic?
When comparing two solutions, the solution with the greater concentration.
When the concentration of two solutions is the same.
When comparing two solutions, the solution with the lesser concentration of solutes.
The tendency of an organism or cell to regulate the chemical processes that take place internally so as to maintain health and functioning, regardless of outside conditions.

What is a difference between diffusion and facilitated diffusion?
movement of particles from [high] to [low]
a protein "helper"
movement of particles from [low] to [high]
energy
The condition in which all acting influences are balanced.
equilibrium
dynamic equilibrium
net movement
occurs when the concentration of particles is higher in one area than another.
concentration gradient
concentration
[high] --> [low]
The relative amount of a given substance contained within a solution or in a particular volume of space; the amount of solute per unit volume of solution. The higher the concentration, the more solute is present.
concentration gradient
concentration
[high] --> [low]

diffusion
osmosis
facilitated diffusion
endocytosis
These organelles collect excess water and then contract to pump the water out of the cell
contractile vacuoles
nucleus
vesicles
golgi body
