Is movement of water from an area of high concentration to an area of low concentration across a?
across semipermeable membrane? That is osmosis, the net movement of water.
What is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low concentration called?
Osmosis
Definition of osmosis?
The movement of water through a semipermeable membrane in order to equalize the osmotic concentration of a solute.Osmosis is the movement of water from an area of high water concentration (low solute) to an area of low water concentration (high solute).
What is the definition for osmosis?
# a physical chemistry,cell biology. ------------------------------ Movement of solvent through a semipermeable membrane so as to equalize the concentration of solute across the membrane.
What Controls the passage of substances into and out of a animal cell?
The semipermeable cell membrane which has two layers of phospholipids controls movement into and out of the cell membrane.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
The larger the concentration gradient (bigger difference between the two solutes across semipermeable membrane) the faster the rate of diffusion.
Is movement of water from an area of high concentration to an area of low concentration across a?
across semipermeable membrane? That is osmosis, the net movement of water.
What is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low water concentration called?
Osmosis
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
What is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low concentration called?
Osmosis
The movement of particals from areas of high concentration to areas of low concentration is called?
Diffusion is the movement of particles from an area of high concentration to an area of lower concentration. Active transport is the movement of substances from lower to higher concentration across a semi permeable membrane that must have a specific protein carrier and cell expenditure of energy.
Definition of osmosis?
The movement of water through a semipermeable membrane in order to equalize the osmotic concentration of a solute.Osmosis is the movement of water from an area of high water concentration (low solute) to an area of low water concentration (high solute).
what is exact definition of osmosis?
Osmosis is the movement of water across a semipermeable membrane from a higher concentration of water to a lower concentration of water without the use of energy.
How long does movement occur across a concentration gradient?
As long as there is a concentration gradient. This is because diffusion occurs which is the net movement of substances from a region of high concentration to a region of low concentration.
Can you have diffusion without osmosis?
Osmosis is the movement of water molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration. Diffusion is the movement of any molecules from a region of higher concentration to a region of lower concentration. so yes it is possible to have diffusion without osmosis.
What is the of definition omasis and an exsample?
movement of a solvent (as water) through a semipermeable membrane (as a living cell) into a solution of higher solute concentration that tends to equilize the concentration of solute on the two sides of the membrane.
What is the definition for osmosis?
# a physical chemistry,cell biology. ------------------------------ Movement of solvent through a semipermeable membrane so as to equalize the concentration of solute across the membrane.
