If a cell contains 97 percent water is placed into a 30 percent sugar solution what will happen to the cell?
The sugar solution is a hypertonic solution so water from the inside will exit through the cell membrane via osmosis and the cell will shrivel
When can 2 solutions not be isotonic?
2 solutions cannot be isotonic when the cell membrane is non-permeable to the solute inside the cell. The solution outside the cell has to be fresh water 0% solute and 100% water
Will iodine molecules diffuse during osmosis?
Yes, Iodine molecules will diffuse from an area of high concentration (hypertonic solution) to an area of low concentration (hypotonic solution). This process continues until the solutions are isotonic i.e. both solutions have the same concentration of molecules on the inside and outside of the cell.
What are the Tonicity of the cell?
Cells can be placed in solutions with higher, lower, or equal concentration to the cell... 1. ISOTONIC: - a solution with equal concentration to the cell. - 0.9% NaCl solutions is isotonic to RBC (red blood cells). - isotonic solutions cause no net gain or loss of water to a cell. 2. HYPOTONIC: - solute concentration is greater on the inside of the cell (or: the outer solution has less concentration than inside). - >0.9% NaCl solutions is hypotonic to RBC (red blood cells). - causes swelling, could burst (lyse) - net gain of water 3. HYPERTONIC: - <0.9% NaCl solutions is hypertonic to RBC (red blood cells). - net loss of water from the cell. - solute concentration is greater on the outside of the cell (or: the outer solution is greater concentration than the inside). - causes the cell shrink (crenation in RBC)
How is a hypertonic solution different from a hypotonic solution?
Hypotonic solution has much less particles dissolved inside the solvent than there is in the cell floating in the mixture. A hypertonic solution has a greater concentration of particles dissolved in the solvent than inside the cell.
Is it possible for an linear programming model to have exact two optimal solutions?
Yes, but only if the solution must be integral. There is a segment of a straight line joining the two optimal solutions. Since the two solutions are in the feasible region part of that line must lie inside the convex simplex. Therefore any solution on the straight line joining the two optimal solutions would also be an optimal solution.

Solutions of water and other molecules are found both inside and outside living cells. what term refers to the salt in a solution of salt and water?
Salt is the solute.

What is the solution that contains more water than what is located in the cells?
A hypertonic Solution. a solution that has a greater concentration of water than the cell content is hypotonic, meaning there is less concentration of water inside the cell, which results in an increase or an expansion of the cell.
What is the liquid in a glow stick?
A glowstick is constructed using a translucent plastic container holding two solutions, one of which is contained inside a glass capsule. The solution outside the capsule is a solution of phenyl oxalate and fluorescent dye. The capsule contains a hydrogen dioxide solution. Upon breaking the capsule and allowing the solutions to mix, the stick will give off a fluorescent glow.
5 percent glucose solution is isotonic for red blood cell if red blood cell are kept in 2 percent glucose solution what will happen to the cells. what such a solution called?
2% glucose solution is considered as a hypotonic solution for that the solution will enter the semi-permeable membrane of the red blood cells causing the cells to explode or burst. Why? It's because RBCs have a higher concentration inside it than that of the 2% glucose solution so the solution will enter the cells.
What are some acids that have pH inside them?
pH is a measure of the concentration of hydrogen ions within a solution. The pH scale runs from 0 to 14. Solutions with a pH less than 7 are considered acids. Solutions with a pH of exactly 7 are neutral. Solutions with a pH of more than 7 are considered bases.

Why does a raw egg swell or shrink when placed in different solutions?
A raw egg without its shell but with its inner membrane intact will either swell or shrink when placed in a solution because of the concentration gradient. The membrane is semi-permeable. An egg will shrink if it is placed in a solution that has a higher solute concentration than inside it. It will swell if it is placed in a solution that has a lower solute concentration than inside the egg.
