What must happen when a concentration gradient is eliminated?
When a concentration gradient is eliminated, there will be no difference in the concentration of a substance across a region. This can lead to equilibrium, where molecules are evenly distributed, or in the case of active transport, energy may be required to maintain the concentration gradient.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
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
If molecules were allowed to move randomly how would they disperse?
If molecules were allowed to move randomly, they would disperse by spreading out from areas of high concentration to areas of low concentration. This process is known as diffusion, and it is driven by the natural tendency of molecules to move from a region of higher concentration to a region of lower concentration to reach equilibrium.
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.
COMPARE osmosis and diffusion?
Diffusion is movement of molecules, from region of higher concentration, to the region of lower concentration, along concentration gradient.
What must happen when a concentration gradient is eliminated?
When a concentration gradient is eliminated, there will be no difference in the concentration of a substance across a region. This can lead to equilibrium, where molecules are evenly distributed, or in the case of active transport, energy may be required to maintain the concentration gradient.
How would diffusion differ from osmosis?
Osmosis is the net movement of water molecules across a semipermeable membrane from a region of a lower concentration to a higher concentration. Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration down a concentration gradient
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is pressure is equal to the tendency of water to enter one solution from another due to a concentration gradient?
Osmotic pressure is the tendency of water to move from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. This process helps to equalize the concentration of solute particles on both sides of the membrane.
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

How do water molecules move during osmosis?
Water molecules move from an area of higher concentration to an area of lower concentration across a semipermeable membrane during osmosis. This movement is driven by the concentration gradient of water.

Which type of transport is used to move a molecule from a region of low concentration to a region o high concentration?
Active transport is used to move a molecule from a region of low concentration to a region of high concentration. This process requires the input of energy, typically in the form of ATP, to move molecules against their concentration gradient.
How long does movement occur across a concentration gradient?
Movement across a concentration gradient occurs until equilibrium is reached, where the concentration of a substance is the same on both sides of the gradient. The rate of movement depends on factors such as the size of the gradient, temperature, and properties of the substance.
