What structure maintains homeostasis by controlling the concentration of solutes within a cell?
Homeostasis is a process that keeps a cell stable. The cell membrane, through the process of diffusion, works to move solutes down a concentration gradient to aid in homeostasis.
How would red blood cell behave in hypertonic solution?
Placed in a hypertonic solution(lower water potential), the red blood cell cytoplasm contains a solution of higher water concentration. Hence water molecules move by osmosis from the red blood cell through its selectively permeable membrane to the hypertonic solution.
What large structure in a plant cell helps it maintain its turgor pressure?
There is a large vacuole present in the middle of the cell that is full of cell sap (a solution of solutes dissolved within water ,negative water potential,) when the plant cell takes up water the water defuses into the vacuole across the concentration gradient (high concentration to low concentration of water) and the vacuole becomes turgid thus making the cell turgid.
What is the name of a cell's environment?
Cells are influenced by the cells and tissues around them. If a person does not drink enough water, each cell can become dehydrated; likewise, if a virus infects one cell, it can easily infect nearby cells.
What is the difference between osmoregulation and osmosis?
In biology, osmoregulation is important to organisms to keep a constant, optimal osmotic pressure within the body or cell. It is the way by which an organism maintains suitable concentration of solutes and amount of water in the body fluids.An example employed by organisms is excretion (such as getting rid of metabolic wastes and other substances toxic to the body when they are in large amounts).However, Osmosis is the dispersion of solutes through a selectively permeable membrane (name changed from semi permeable) from an area of high concentration to low concentration.
What is a solution that neither shrinks nor swells a cell?
A cell placed in an isotonic solution will not shrink or swell. Isotonic means that the concentration of solutes in the solution is equal to the concentration of solutes within the cell. Since both concentrations are the same, no water flows in or out of the cell due to osmotic pressure.
Is antiseptic iodine a solution or solvent?
The liquid product is a solution. The iodine is one of the solutes within the solution.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
What contains substance called solutes dissolved within a solvent?
solution

Does hypertonic shrink?
A hypertonic solution does shrink. It is when the osmotic pressure is greater than the solution that is within it.

Calculating concentration gradient?
The gradient can be calculated by comparing the solute particles from one solution with another. Distance determines the gradient levels within the solution.
What happens to a cell plant cell or animal cell when placed in following solution a hypotonic solution b isotonic solution c hypertonic solution?
When placed in an isotonic solution (i.e. a solution where the concentration of water molecules is roughly equal to the that within cells), there is equal diffusion of water into and out of the cells. Therefore, the cells find this environment suitable. In a hypotonic solution (i.e. a solution where the concentration of water molecules is much more than that within cells) water diffuses into cells as a result of which the cells swell. Excessive swelling causes the cells to burst, a phenomenon called cell lysis In a hypertonic solution (i.e. a solution where the concentration of water molecules is lesser than that within cells) water moved out from within cells to the surrounding medium. As a result of this, cells shrink.

What is the effect of isotonic salt solution on rbc?
Iso means same, therefore the salt solution concentration is the same as the concentration of salt within the blood cells. So nothing happens - the RBC's remain the same (no shrinking/crenating or swelling/lysing)
