What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What is the movement of solute from a region of high concentration to one of lower concentration?
Diffusion; a form of passive transport.
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.
What is diffusion across a biological membrane?
It is when molecules in a cell naturally move from a high-density area in the cell to one of lower density.
What mechanism are active?
Active transport mechanisms occur when particles move from a region of lower concentration to one of higher concentration. This requires energy, which comes from cellular metabolism and, specifically, from a molecule called adenosinetriphosphate(ATP).
What is it called if the concentration of a substance from one region is different from the concentration in an adjoining region?
This is a concentration gradient.But because the phenomenon of diffusion concentration will become the same everywhere.
What is movement of solute from one region of high concentration to one of lower concentration called?
Are called osmosis
Which would most likely cause the liquid in Tube A to rise?
water passing from a region of lower starch concentration to one of higher starch concentration

What does the word diffusion mean?
it is the transport of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
What is diffusing in science?
Diffusion is a net transport of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
What is the movement of solute from a region of high concentration to one of lower concentration?
Diffusion; a form of passive transport.
What happens in the process of diffusion?
During diffusion molecules move from a region of higher concentration to one of lower concentration by random molecular motion.
During the process of diffusion what happens?

What is the difference in concentration between a region of high concentration and one of lower concentration?
There is no exact number assigned to the difference between the higher and lower concentrations. However, the establishment of a concentration differential is essential for both diffusion as well as osmosis.
