What would occur if a semipermeable membrane has a 4 percent salt solution on the right side and a 12 percent salt sodiumon tsolution on the left side?
If a semipermeable membrane separates a 4 percent salt solution on the right side from a 12 percent salt solution on the left side, water will move from the area of lower solute concentration (the 4 percent solution) to the area of higher solute concentration (the 12 percent solution) in an attempt to equalize the solute concentrations on both sides. This process, known as osmosis, will continue until equilibrium is reached, resulting in an increase in the salt concentration on the right side and a decrease on the left side.
In which direction would osmosis occur if 15 percent sugar solution is separated from a 25 percent sugar solution?
It would flow toward the weaker solution. The intent of osmosis is to gain equilibrium, so the 15 percent solution would gain sugar content until, if you allowed the osmosis to go to completion, the two solutions had the same amount of sugar in them. "Going to completion" doesn't necessarily mean 20 percent concentration on both sides. If you were to make a gallon bag out of dialysis membrane, fill it with 15 percent solution and put a stirrer in it, then drop it into a 25,000-gallon reaction vessel full of 25 percent solution with a stirrer in it, you might wind up with 24.9999999999 percent sugar solution in both bags.
Does glucose move into the sac?
Yes, glucose can move into the cell through facilitated diffusion using glucose transport proteins on the cell membrane. The concentration gradient allows for passive transport of glucose molecules into the cell.
Cell membranes that allow certain molecules to pass through while keeping others out are called?
semi permiable I believe, but I'm not 100 percent sure on the spelling selectively permeable
How much solvent must you add to 1 ml of a 50 percent solution to make a 10 percent solution?
To make a 10 percent solution, you would need to dilute the 50 percent solution by adding 4 ml of solvent to 1 ml of the 50 percent solution. This will result in a total volume of 5 ml with a 10 percent concentration.
A semipermeable membrane has 2 percent salt solution on one side and a 15 percent salt solution on the other side what will most likely occur?
Osmosis of water from a low concentration of salt to a high concentration
A semipermeable membrane has 2 percent salt solution on one side and 15 percent salt solution on the other side. What will most likely occur?
Osmosis of water from a low concentration of salt to a high concentration

A semipermeable membrane has an 8 percent salt solution on the left side and a 9 percent on the right side what will most likely occur?
There will be movement of water by osmosis from the less-concentrated solution (left) to the more-concentrated solution (right). Water will tend to flow from a more-dilute state to a less-dilute state.
If 2 percent glucose solution and 5 percent glucose solution are separated by a semipermiable menbrane flows from the 2 percent glucose solution to the 5 percent glucose solution?
Yes, during process of osmoses the solvent from higher concentration to lower concentration moves through semipermeable membrane, the 2% solution has lower concentration of solute therefore higher concentration of solvent.

If a 10 percent sugar solution is separated from 20 percent sugar solution by a selectively permeable membrane in which direction will there be net movement?
The direction will be towards the more concentrated side so the 10% solution with go towards the 20% solution in an attempt to reach equilibrium.
Why can a transfusion of 5 percent salt solution be fatal?
This is due to osmosis. Osmosis is the process by which molecules of a solvent (in this case water) tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated solution until it is of equal concentration.If you have an isotonic saline solution of 0.9% (used in hospitals) the dissolved salt concentration in the saline is the same as the dissolved solute concentration in human blood. Therefore, the water molecules are able to pass through the semipermeable membrane of a red blood cell at the same rate. Remember semipermeable means some molecules can pass through but others cannot. The charged ions of salt cannot pass through the red blood cells membrane.If you had a hypotonic saline solution of 0.1%, the water molecules would try to equalise the concentration by moving across the red blood cell membrane into the cell until it ruptured.If you had a hypertonic saline solution of 5%, the water molecules would try to equalise the concentration by moving across the red blood cell membrane out of the cell until it completely shriveled up.Shriveled up red blood cells cannot function properly to transport oxygen abound your body, which would be fatal.
Does glucose move into the sac?
Yes, glucose can move into the cell through facilitated diffusion using glucose transport proteins on the cell membrane. The concentration gradient allows for passive transport of glucose molecules into the cell.
If A semipermeable sac containing 4 percent NaCl 9 percent glucose and 10 percent albumin is?
suspended in a solution with the following composition: 10% NaCl, 10% glucose and 40% albumin.
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution How much of the 20 percent solution did the pharmacist use in the mixture?
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution. How much of the 20 percent solution did the pharmacist use in the mixture (in liters).
What appearance will red blood cells have when they are placed in 90 percent NaCI?
9% NaCl is a hypertonic saline solution. Red blood cells will appear to shrink as they lose water out of the cell membrane and into the saline solution.
