Concentration of this substance...it normally goes from a higher concentration to the lower....

it has to do with individual concentrations such as if one ion is in higher concentration on one side of the membrane it will move across the membrane to the other side... However, if you have a semipermiable membrane, and thus only certain ions or molecules can get through it will move base on a osmolarity basis and thus you need to total up the overall charge and or displacement of the medium (i.e. water) which may also determine which way substances diffuse.

Diffusion is a process that does not require extra energy.
A substance diffuses across the membrane from the place with bigger concentration of the substance to the place with lower concentration.

A concentration gradient. Substances diffuse from an area of higher concentration to an area of lower concentration.
So if there's lots of Sodium on one side of a membrane and very little on the other, then the sodium will move from the side with a lot of it to the side with very little of it.
Hope this helps!

1) The permeabilityof the membrane.
2) The concentration of solutes on each side of the membrane.

Transport of molecules against a concentration gradient (from regions of low concentration to regions of high concentration) with the aid of proteins in the cell membrane and energy from ATP.
(Active transport).

A substance will go to wherever the concentration of it is less.

The difference in the concentration of the two solution.

sounds like gravity pulling,,,a substance moves due to the attraction of gravitation in which the membrane or another part of the body exerts on an object or near its surface...sounds to sexual to me....

It typically tries to move to the side with the least concentration.
