Molecules can travel from low to high or from high to low,until they reach equilibriums.

however, they are able to move from low to high using the process called active transport, this however uses energy (*normally in the form of ATP), this is only ever really used in organisms.

Molecues move by diffusion from a region of their Higherconcentration to a reigon of their lower concentration, down their concentration gradient.
In diffusion, molecules travel from a higher concentration to a lower concentration. When you put a drop of ink in a glass of water, the spreading of the ink in the water is called diffusion. Similarly, if you spray an air freshener in one corner of a room, eventually people on the other side of the room will be able to smell it as well because the scent has diffused. In osmosis, molecules also travel from higher concentration to a lower concentration. However, osmosis specifically refers to the movement of WATER molecules. Both of these types of transport are examples of passive transport, which requires no energy.

Molecules tend to travel from a concentration from high to low. A cell will reach equilibrium when the concentration gradient has become equal on both sides of a cell (inner and outer membrane). A cell will reach what is called "dynamic equilibrium" when the concentration gradient of a cell is equal, but molecules still move back and forth in the same proportions.
Diffusion and active transport are not the same thing. Diffusion is when molecules pass from an area of high concentration to an area of low concentration. They travel down a concentration gradient. They do this naturally, like if perfume is sprayed at one end of the room, it spreads to the other end, because there is a low concentration of spray at the other end, see? Active transport is when a cell actively moves molecules from one side of its membrane to the other. It is often travelling up a concentration gradient, so it is going from an area of low concentration to an area of high concentration- the opposite of diffusion.
increasing the agarose concentration will enable the separation of smaller fragments of DNA. the structure of the gel (agarose) consists of crosslinks, therefore the higher the concentration of agarose the more crosslinks there will be and smaller size "holes" for the DNA to travel through (also the other way around, with less concentrated agarose)
Molecules travel across the cell membrane from a higher concentration to a lower concentration during both osmosis and diffusion. Diffusion is when molecules move across the cells' membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.

Osmosis is the tendency of a solvent to travel across a semipermeable membrane (Semipermeable membrane- a membrane that allows some molecules to pass through but does not allow other molecules to pass through) into areas of higher solute concentration. Diffusion is the random motion of molecules from an area of high concentration to an area of low concentration.
Diffusion is when molecules travel from a higher concentration to a lower concentration. For example when you have air freshener on one side of the room it will spread to the other because the scent molecules are diffusing through the air. Osmosis is the movement of water molecules from higher concentration to a lower concentration.

Molecules move faster the more energy they have ie the higher temperature they are. If you are talking about the 3 classical states, then the molecules will travel fastest as a gas

They always travel from an area of high concentration to an area of low concentration due to the idea of diffusion. Diffusion definition: the net movement of individual particles from an area of high concentration to an area of low concentration due to the random movement of individual particles.
When a region of higher concentration to a region of Lower concentration against the gradient which requires Energy is called Active Transport
