Is salt water diffusion or osmosis?

Salt triggers osmosis by attracting the water and causing it to move toward it, across the membrane. Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution.

Can diffusion happen in salt water?

Salts and sugars in solution will diffuse away from areas of high concentration into the surrounding solution. This is called simple diffusion. Water also diffuses away from areas of high free water concentration into areas of more solute concentration. Thus, only water can diffuse.

How the use of distilled water in place of this saline solution would be expected to upset the patient’s homeostasis?

Explain how the use of distilled water in place of the saline solution would be expected to upset the patient’s homeostasis. The process of osmosis would cause water to move into the cells causing them to swell and possibly burst.

Which of the follow answer choices best explains why contractile vacuoles would be of little value to one celled organisms living in the ocean salt water *?

Explain why contractile Vacuoles would be of little value to one- celled organisms living in salt water. This is because in a hypotonic solution water will enter the organism because there is more solute inside the cell than outside the cell.

Is diffusion involved in osmosis?

Explanation: Osmosis is a special type of diffusion. Osmosis is the diffusion of water molecules across a selectively permeable membrane. It will move from a high level to a low level.

Which way will water diffuse?

Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water. Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction.

How is osmosis like diffusion?

Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.

What would most likely happen if a patient is given distilled water 100% water instead of an isotonic saline solution through an IV Why?

When a person receives fluids intravenously (through an IV bag, for example), a saline solution is sometime used. Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.

Did any starch diffuse out of the cell?

Starch did not diffuse through the membrane. Explain why some substances were able to pass through the membrane while others were not able to. Some substances were able to pass through because the cell is a semipermeable. This means it will only allow some substance to pass in.

Why are contractile vacuoles useless in salt water?

In salt water, the solute concentration outside the cell is more than inside the cell so the water flows out of the cell down the concentration gradient. Therefore contractile vacuoles are not required for expelling water.

What would most likely happen if a patient is given distilled water 100% water instead of an isotonic saline solution through an IV?

What is the difference between osmosis and water diffusion?

Diffusion is the movement of particles from a region of high concentration to low concentration while osmosis the movement of water molecules via a semi-permeable membrane from dilute to the concentrated solution. Water molecules are the diffusing molecules in osmosis while diffusion can be solid, gases and liquid.

Is osmosis an active or passive transport process?

Osmosis is a passive process. The movement in diffusion is to equalize concentration (energy) throughout the system. The movement in osmosis seeks to equalize solvent concentration, although it does not achieve this. Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution.

Does diffusion require a semipermeable membrane?

Diffusion does not require a semipermeable membrane. Osmosis requires a semipermeable membrane. The concentration of the diffusion substance equalizes to fill the available space. The concentration of the solvent does not become equal on both sides of the membrane.

What is the relationship between turgour pressure and osmosis?

Osmosis depends on the rate of reduction of free energy of one solvent. At the end of diffusion process, the concentration of the diffusing particles will be equalized. Diffusion is not influenced by the turgour pressure. Osmosis is hindered by the turgour pressure of the cell.
