What substances in the blood pass through the partially permeable membrane into the kidneys?
As the dialysis fluid has no urea in it, there is a large concentration gradient - meaning that urea moves across the partially permeable membrane, from the blood to the dialysis fluid, by diffusion. This is very important as it is essential that urea is removed from the patients' blood.
What are the characteristic of cell membrane?
The cell membrane is selectively permeable. It is also very flexible and contains many different substances within it and on it, such as various proteins, lipids, cholesterol, etc, nicknaming it the fluid mosaic model.
How does temperature correlate to the permeability of the cell membrane?
Cell membranes act very much like a fluid on a molecular level. The phospholipids move around each other with relative ease, making the membrane flexible. With an increase in temperature, the molecular movement will increase throughout the membrane thus leading to looser fits among molecules and a more permeable membrane.
Do sperm cells have a cell membrane?
Yes, sperm cells have a cell membrane. The cell membrane is a thin, semi-permeable barrier that surrounds the cell and helps regulate the movement of substances in and out of the cell.
How are hypertonic solution and hypotonic solutions similar?
In osmosis, the hypertonic solution is one with a higher solute concentration over the semi-permeable membrane and the hypotonic solution is one with a lower solute concentration over the semi-permeable membrane. The similarities between these two is that both contain a solute and both involve water which is essential in osmosis. Also, the semi-permeable membrane plays a very important roll on how the water moves. It moves from the lower solute concentration to the higher solute concentration.
How do particles move through a permeable membrane according to diffusion?
Yes, that is very true, especially with osmosis (the passing of water through a selectively permeable membrane).
How I can use cell membrane in a sentences?
cell membrane is the most outer part of a cell. cell membrane is very big in surface.
What is made up of a mixture of many types of molecules and is very thin and selective permeable?
cell membrane
What characteristics make the cell membrane unique?
Cell Membrane is a semi-permeable part of a cell which takes part in exchanging enzymes, proteins or nutrients in between the environment and the cell. The Cell Membrane has a very lively effect to it and acts as a coating which also protects the cell in many ways.
What features does a cell have?
Well, it has a strong, not very permeable membrane. This is so the sperm cell find it harder to penetrate and only one (usually) can enter.
Does osmosis require a semipermeable membrane?
Semi permeable membrane means a very thin layer of material which allows some molecule to pass through them and prevent some molecule to pass through them. Osmosis is the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. So the membrane should be semi-permeable so as to only allow the movement of H2O molecules and not the other molecules of the mixture.

How does ultrafiltration get cleaned and filtered?
Ultrafiltration water treatment utilizes a semi-permeable membrane to ... Membrane cleaning may be achieved by allowing a very small portion of the flow to exit ... Filtration can also be carried out from the "outside-in" .
Through what parts of the nucleus do materials enter and leave?
Nucleus is enclosed in double walled nuclear membrane. Nuclear membrane at certain distance have pores in them which are called nuclear pores. Nuclear pores are very selectively permeable.
Is water always able to diffuse through a cells selective permeable membrane?
Yes, due to its very small molecular size - unless of course it is frozen.
