Concentration. It will generally flow from an area of high concentration to an area of low concentration.

What are the similarities between diffusion and facilitated diffusion?
Diffusion is the main method by wich small molecules move across the cell membrane. while many cellular processes depend on osmosis because cells cannot function properly without adequate water. Facilitated diffusion works through channels and Osmosis only works with water.
What does the net flow of water molecules in osmosis depend on?
The magnitude of the concentration gradient across the membrane.
Can you have 5 living organisms that depend on diffusion?
All living organisms depend on diffusion.Organisms that rely on diffusion alone are almost always single celled organisms.
How does diffusion coefficient depend on the molecular properties of the solute and solvent?
It doesn't. Ever since it was a child it has been a free spirit. It's parents expected it to depend on at least one of the two, but the diffusion coefficient just wanted to dance.
How can diffusion occur in one direction?
Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.Explanation:Diffusion is a passive process. It is like when you open a bottle of perfume, soon the whole room will be covered with its smell. From region where the concentration is high, the molecules move to the regions where the concentration is low down the concentration gradient unless equilibrium is reached. Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.

The magnitude of the concentration gradient across the membrane.
Facilitated diffusion and active transport?
Facilitated diffusion = down concentration gradient, it just uses a carrier protein (doesn't need energy)Active transport =goes UP concentration gradient with the help of a carrier protein and ENERGY
What does diffusion not have to depend upon?
energy

What is the process called when molecules pass through a membrane to a different conecntration?
This would depend on A) the molecule B) the membrane/proteins involved, and C) the concentrations.Diffusion in general would be the passage of molecules from an area of higher concentration to an area of lower concentration.This can be broken down into either FACILITATED DIFFUSION(through specialized integral protein channels) or SIMPLE DIFFUSION (through the membrane itself, only with tiny uncharged particles).ACTIVE TRANSPORT is normally from an area of lower to higher concentration and requires ATP expenditure.
What process the cell must use to allow the protein to enter and why?
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.
What controls the passage of materials into and out of the cell?
depend on the kind of cell...... plant: cell wall and cell membrane/plasma membrane animal: cell membrane/plasma membrane
Does displacement depend on direction?
yes

Does the instantaneous speed depend on the direction?
Maybe
Why does a blimps movement not depend on the direction wind?
No
