What else can I help you with?
Why did the number of the water molecules on each side of the membrane change where as the number of sugar molecules stayed the same?
The membrane is permeable to water but not to sugar.
What does osmosis do?
The random movement of water molecules through a partially permeable membrane from a higher concentration to a lower concentration.
What is aquaporins?
Aquaporins are protein molecules embedded in the phospholipid bilayer (cell membrane ) of some cells. They transport water across the cell membrane.
How does the bilayer mambrane act as a barrier between two aqueous areas?
The bilipid membrane is essentially fat. It is non polar. The intracellular and extracellular fluid is made up of water and water soluable molecules which are polar. Since like dissolve like, the fluid isn't able to pass directly through the membrane. Instead molecules like ions go through selective channels. Other fat molecules like steroids and alcohol can pass straight through the membrane because thet are also nonpolar. To be more specific, the fat molecules basically merge into the membrane and reform as they
Osmosis is a diffusion process that moves through the membrane from higher to lower concentration. molecules salt water nutrients?
Switch the word "solvent" to "water" and you have the best definition possible.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
How does the presence of a semipermeable membrane affect the movement of water molecules during osmosis?
The presence of a semipermeable membrane during osmosis allows water molecules to pass through while blocking larger molecules. This causes water to move from an area of higher concentration to an area of lower concentration, balancing the concentration on both sides of the membrane.
Why does osmosis require a semipermeable membrane while diffusion does not?
Osmosis involves the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The presence of a semipermeable membrane is necessary to prevent the movement of solute molecules while allowing water molecules to pass through. Diffusion, on the other hand, is the movement of molecules from an area of higher concentration to an area of lower concentration and does not require a membrane for movement.
How does the process of diffusion of water molecules across a semipermeable membrane occur?
Diffusion of water molecules across a semipermeable membrane occurs through a process called osmosis. Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration, through the semipermeable membrane, in order to equalize the concentration on both sides. This process is driven by the natural tendency of molecules to move from areas of high concentration to areas of low concentration until equilibrium is reached.
How does osmosis occur across a semipermeable membrane?
Osmosis occurs across a semipermeable membrane when water molecules move from an area of higher concentration to an area of lower concentration, in order to balance the concentration of solutes on both sides of the membrane.
Water molecules will no longer pass through the semipermeable membrane once equilibrium is reached true or false?
False. There will still be movement of water molecules across the membrane, but there will be no net movement. This means that the number of molecules coming into the cell will equal that going out, and equilibrium will therefore be maintained.
The diffusion of water across a semipermeable membrane is called?
When water diffuses through a semipermeable membrane, such as a cell, it is called osmosis. In osmosis the concentration of water will differ on one side of the membrane from that of the other side. Water molecules will tend to diffuse from the high concentration side to the lower.
What is the term of diffusion of water across a semipermeable membrane?
The term for the diffusion of water across a semipermeable membrane is osmosis. Osmosis is when the molecules of a solvent move from a less concentrated solution to a more concentrated one. This equalizes the concentrations on each side of the member.
What term describes the diffusion of the water through a semipermeable membrane down a concentration gradient?
Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane
Which type of molecules cross the membrane in osmosis?
Water molecules cross the membrane during osmosis. Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
In the process known as osmosis what moves through a semipermeable membrane into an area of concentration?
In osmosis, water molecules move through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the solute concentration on both sides of the membrane.
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
