When the concentration of a substance differs from one area to another this is called concentration?
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
What term describes the different in the concentrations of a substance across a cell's membrane?
concentration gradient
The movement of a substance from where there is large amounts and low amounts?
This is called diffusion. Substances move randomly, from an area of high concentration to an area of low concentration. Osmosis is a specific type of diffusion that only involves the random movement of water.
A concentration gradient ceases to exist when?
A concentration gradient ceases to exist when there is an equal distribution of a substance across a space or membrane. This equal distribution results in no net movement of the substance from one area to another, causing the concentration gradient to reach equilibrium.
While conducting an experiment you discover a certain substance passing out of a cell by diffusion what might you conclude about the concentration of this substance?
If a substance is passing out of a cell by diffusion, it suggests that the concentration of the substance is higher inside the cell than outside. This movement is driven by the substance's tendency to move from an area of higher concentration to an area of lower concentration to reach equilibrium.

How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
What is the difference between the concentration of a particular molecule in one area and the concentration in an adjacent area?
The concentration gradient is the difference in concentration of a molecule between one area and an adjacent area. This difference creates a gradient that drives the movement of molecules from an area of higher concentration to an area of lower concentration, a process known as diffusion.
What is the movement of a substance from an area of great concentration to an area of lesser concentration?
Molecular Diffusion
For diffusion to occur which condition must be met?
Diffusion occurs when a substance moves from an area of high concentration to an area of low concentration. This will happen naturarally without disruption, But is more common (and will happen faster) in a warm environment.
What determines the direction in a substance diffuses across a membrane?
The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.
What term describes the different in the concentrations of a substance across a cell's membrane?
concentration gradient
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
What is a concentration gradient?
It is the difference in concentration (molecules of a solute per volume of solution) between two locations. Because of the motion of molecules, they are said to diffuse (move, spread) from an area of greater concentration to an area of lesser concentration. Some molecules are always moving in the opposite direction, but the overall trend is "down" the gradient until equilibrium is established between the two regions. And, generally, the larger the gradient or difference, the faster the rate of the diffusion.
What driving force Ofdiffusion?
The driving force of diffusion is the concentration gradient, which is the difference in concentration of a substance between two areas. Substances will move from an area of higher concentration to an area of lower concentration in order to reach equilibrium.

This is called diffusion. Substances move randomly, from an area of high concentration to an area of low concentration. Osmosis is a specific type of diffusion that only involves the random movement of water.
When a substance moves from an area of low concentration to an area of high concentration while using energy the processed is term is?
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
