What is diffusion simple?
Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient. Simple diffusion does not require energy therefore it is 'passive', substances are diffused across the membrane between the phospholipids.
A cell that is 35 percent water is placed in a solution that is 35 percent water Which way will the net movement of water go?
In this scenario, the cell and the surrounding solution have the same water concentration (both are 35 percent water). This means that the system is in an isotonic state, where the concentration of water inside the cell is equal to the concentration of water outside the cell. In an isotonic solution, there is no net movement of water. Water molecules will move across the cell membrane in both directions, but there is no overall change in the water concentration inside or outside the cell. The cell's volume and shape will remain relatively stable. In summary, if a cell that is 35 percent water is placed in a solution that is also 35 percent water, the net movement of water will be minimal, and the cell will generally maintain its size and shape.
What is the assive process that is movement of a substance from an area of high to low concentration?
a passive process is any process that occurs without an input of energy. the process of a substance moving from a high area of concentration to an area of low concentration in order to obtain equilibrium is the process of diffusion, this requires no energy input therefore it is a passive process. Diffusion is a property of atoms. atoms move randomly but overall the net movement of atoms will always be to spread away from a high area of concentration. the reason for this can be explained by considering a perfume bottle. once opened the gas in a perfume bottle has the ability to escape, the reason the perfume leaves the bottle (this is just a theory) is because there are only so many ways that the atoms in the perfume bottle can be arranged but there is trillions of more ways that the atoms can be arranged outside of the bottle so probability tends towards the perfume escaping the bottle and spreading out in the room.
Which term describes the movement of water molecules in and out of a cell?
its not diffusion at all, but i think you mean osmosis. it has nothing to do with water concentration so it is a completely distinct mechanism. osmosis works as the amount of free water decreases as the amount of solute increase. we refer to the proportion of water in this free state as Ψ (psi). solutions with a lower Ψ have more solutes in them and therefore water will travel across a partially permiable membrane down the Ψ gradent, until the amount of free water is the same. the maximum Ψ possible (for comletely pur water) is 0.
What would happen to a cell in an isotonic solution?
Diffusion occurs in equilibrium, which means the molecules still move in and out of the cell, but the net (overall, total) movement is 0.
What happens to a particle in diffusion?
When particles diffuse they break apart, down into simpler substances. Diffusion is the net movement of molecules from high to low concentration through random motion. From the particle point of view it just moves about at random (as usual) but the overall effect is for the particles to spread out evenly.
How does sand and gravel size influence hydraullic conductivity?
The smaller the grain, the less pore space there is to allow fluid movement. The larger the particle grains, the greater the movement due to the overall increase in pore space between particles.

What is overall movement of water?

Where can find lowest concentration of nitrogen in urine?
The lowest concentration of nitrogen can be found in the urine when it is first produced. As it accumulates in the bladder, so does the overall concentration of nitrogen.

What is an atom or molecule with electric charge?
In chemistry, particles with an overall electric charge are called ions.
What is the meaning of phototripism?
a source of light, without overall movement of the whole organism
Can you charge a patient for continuous treatments for wart removal?
Yes, if the service is provided per session instead of as part of an overall treatment.
What is the prosses of osmosis?
Osmosis is the overall movement of water through a partially permeable membrane.
Explain the relationship between local particles vibrations and overall wave motion?
Most waves are caused by a vibrating object. Electromagnetic waves may be caused by charged particles.
