Maybe you mean osmosis?
However, osmosis is not the same as diffusion of water. Diffusion of water is just diffusion like with any other substance: the particles spreading, making a homogeneous distribution. Osmosis involves a semipermeable membrane, where water goes from low solvent concentration to high solvent concentration.
answ2. However, in the oceans, the turbulence is very much less than that of the air. Thus whilst C14 for example diffuses reasonably rapidly in the air, and may be assumed to homogenize after a few years; in the oceans the rate of diffusion is very much slower.
And the oceans are known to stratify. For example in the Fiords in New Zealand, there forms a fresh water layer on top of the sea water, and this is known to freeze in winter. The ocean water itself in the same locale never gets cold enough to freeze.
No. Water tends to diffuse from a region where it (water) is more concentrated to a region where it (water) is less concentrated. The other way of thinking about this is that water diffuses from an area of high solute concentration to an area of low solute concentration.
water tends to diffuse from an area of lower concentration to an area of higher concentration.

water trends to diffuse from a region where it is less concentrated to a region is highiy concentrate.
osmosis. The water moves down an osmotic gradient from a dilute solution of ions to a move concentrated solution through a partially permiable membrane.
Dissolved particles on one side of the membrane results in the diffusion of water across the membrane due to the need to have the same solution concentration on both sides of the membrane. Water will diffuse from a hypotonic solution to a hypertonic solution.
osmosis
Osmosis
You are correct. A hypertonic solution is a solution outside the cell that has more solute in it that water. This means that there is more water inside the cell than solute. Because there is more water in the cell, it will diffuse out of it and the cell will shrivel up.
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
true
No, it goes from HIGH concentration, to LOW concentration
No. Water tends to diffuse from a region where it (water) is more concentrated to a region where it (water) is less concentrated. The other way of thinking about this is that water diffuses from an area of high solute concentration to an area of low solute concentration.
It is not true. All substances tend to diffuse from an area of higher concentration to that of lower concentration. This is called passive transport(no energy required), or in the case of water, Osmosis. However, if given energy, they can also move from an area of lower concentration to that of higher concentration. This process is called active transport.
A sponge gets its oxygen from the water. The oxygen moves from the water to the sponge by a process called diffusion. Diffusion is when molecules of a substance move from an area where they are highly concentrated (where there are a lot of oxygen molecules) to an area where they are less concentrated (where there are not a lot of oxygen molecules). Oxygen is more highly concentrated in the water then in the sponge. Therefore, the oxygen goes from the water to the sponge.
Not just plant cells, all cells with semi-permeable membranes loose water when placed in a more highly concentrated solution.
Yes, osmosis is defined as the net movement of water molecules from an area where they are highly concentrated to an area where they are less concentrated across a semi-permeable membrane such as a cell surface membrane.
Insoluble salts doesn't diffuse in water.
Gummy bears get larger when put in fresh water, but not in salt water. It is due to the action of osmosis, which means that water from a region where it is more highly concentrated to an area where it is less concentrated through a semi-permeable membrane. This continues until the two sides of the membrane equalise - thus the gummy bear swells.
The water in the dialysis bag would diffuse out into the molasses solution. This is because there is a high concentration of water inside the dialysis bag and a a lower concentration of water in the molasses solution. By diffusion or osmosis, the water would tend to move from the concentrated bag to a less concentrated solution.
There is a natural tendency for a substance to move from a region of high concentration to a region of low concentration (see osmosis). This means that even water moves from its region of abundance to its region of shortage. Since salt water is more concentrated (less water) than the contents in your mouth (including any germs in there), when you gargle with it, it tends to draw water out of bacterial cells (which have more water in them). All cells are over 70% water and require water to function effectively and hence survive. If the salt water is concentrated enough, it will kill most germs in the mouth and some from the throat.
the lungs causes oxygen from the water to diffuse into the blood
