Water moves both ways across a membrane (into and out of a cell). The net (total) change depends on how much water is moving each way (which depends on a lot of factors like salinity, concentration, charges, temperature, etc).

How charged particles like Na and K move across membranes?
ion pumps
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
What are Transports that requires energy from ATP to move substances across membranes?
active transport
Is it from high concentration to low that particles move across a membrane move?
Yes. It is called Osmosis. Particles move across the membrane in order to balance the concentration of particles on both sides of the membrane. Since the membrane tends to block the larger particles, its the smaller molecules that move, so what happens across membranes is that the motion (of say water) is from low concentration toward higher - but the result is to even the concentration on both sides of the membrane, Pure diffusion is always from higher concentration to lower.
During osmosis which direction does the water move into the cell out of the cell or does it move in and put equally?
During osmosis water moves in and out of the cell equally in both directions.
How fluids move across capillary membranes?
Osmosis.
What type of waves move across the direction of travel?
Transverse waves will move across the direction of travel.
In water waves water particles move in?
Water particles (molecules) move transversely to the direction of propagation of the wave. That means that as the wave moves out across the water, which is its direction of propagation, the water molecules move up and down (transversely) to create the crests and troughs of the wave.
Which of the following processes cause substances to move across membranes and doesent require energy ATP?
diffusion or osmosis (diffusion of water)
What are Passive processes that move substances across membranes?
Diffusion ,osmosis
What passive process that move substances across membranes?
Diffusion ,osmosis
What direction do molecules of osmosis move?
Osmosis is not a molecule. It is the flow of water through cell membranes from areas of high concentration to areas of low concentration.
How do larger molecules move across epithelial membranes in capillaries?
by exocytosis and endocytosis
What would happen to a cell if materials could not move across the cell membranes?
it will died
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure
How charged particles like Na and K move across membranes?
ion pumps
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
