What is the movement of solutes from areas of high concentration to areas of low concentration?
The movement of solutes from areas of high concentration to areas of low concentration is called diffusion. This process occurs passively and does not require energy input. Diffusion helps in achieving equilibrium in the concentration of solutes across a membrane or within a solution.
What type of solution do animal cells prefer?
Animal cells prefer an isotonic solution, where the concentration of solutes inside and outside the cell are equal. This allows for the proper balance of water and nutrients to be maintained within the cell, promoting normal function and preventing dehydration or swelling.
What structure maintains homeostasis by controlling the concentration of solutes within a cell?
The cell membrane, specifically through transport proteins such as ion channels and pumps, plays a key role in maintaining homeostasis by controlling the concentration of solutes within a cell. These proteins regulate the movement of ions and molecules in and out of the cell, helping to balance the internal environment with the external environment.
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.
How does osmosis maintain body cells at a specific concentration?
Osmosis helps maintain the specific concentration of body cells by allowing water to move in and out of the cells to achieve equilibrium. When a cell is in a high concentration solution, water will move into the cell to dilute the solution. Conversely, when a cell is in a low concentration solution, water will move out of the cell to try to equalize concentrations. This process helps keep cell concentrations within a narrow range for proper function.
What is the movement of solutes from areas of high concentration to areas of low concentration?
The movement of solutes from areas of high concentration to areas of low concentration is called diffusion. This process occurs passively and does not require energy input. Diffusion helps in achieving equilibrium in the concentration of solutes across a membrane or within a solution.
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.
What contains substance called solutes dissolved within a solvent?
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 type of solution do animal cells prefer?
Animal cells prefer an isotonic solution, where the concentration of solutes inside and outside the cell are equal. This allows for the proper balance of water and nutrients to be maintained within the cell, promoting normal function and preventing dehydration or swelling.

These proteins regulate the movement of ions and molecules in and out of the cell, helping to balance the internal environment with the external environment.
How does potassium affect osmotic pressure?
Potassium ions contribute to osmotic pressure by affecting the concentration of solutes in a solution. When potassium ions are present in a solution, they increase the overall solute concentration, which in turn increases the osmotic pressure of the solution. This means that higher levels of potassium can lead to an increase in osmotic pressure.
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.
Does hypertonic shrink?
A hypertonic solution does shrink. It is when the osmotic pressure is greater than the solution that is within it.
When more solvent is added to a solution to decrease its concentration it is called?
When more solvent is added to a solution to decrease its concentration, it is called dilution. Dilution involves reducing the concentration of solute particles within the solution by adding more solvent to increase the total volume.
How does heat effect on solutions?
Heat can affect solutions by increasing the rate of dissolution of solutes, increasing the solubility of certain solutes, and changing the viscosity of the solution. Additionally, heat can also cause chemical reactions within the solution to proceed at a faster rate.
What is the concentration of the cytoplasm of a potato cell?
The concentration of the cytoplasm in a potato cell is typically around 10-20% due to the presence of various solutes such as sugars, salts, and proteins. This concentration allows for proper cellular functions and osmotic balance within the cell.
