Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.

What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
Which cell allows oxygen to pass through quickly is it thin is it thick?
they have a large surface area to allow a lot of oxgen to difuse acroos. in other words to allow for efficent gas exchange. they also have an excellent blood supply
Why is the cell membrane described as a phopholipids?
Cell membranes are made up of a phospholipid bilayer.. they have a hydrophilic (water loving) head and two hydrophobic (water fearing) tails. Phospholipids contain a phosphate group and a lipid group, that's why they are called that.
How is facilitated diffusion different than normal diffusion?
Diffusion is the movement of molecules or partocles from an area of high concentration to an area of lower concentration, and Facilitated diffusion is when substances difuse across cell membranes more rapidly than you might expect.
How do water molecules behave?
Ionic bonds are mainly the weakest bond; it is weaker than hydrogen bonds. Aside from that, hydrogen molecules are cohesive. Salt is NaCl, which is an ionic bond. It easily dissolves in water. Plus, if there are too much ions in the water, electricity could channel in it. Although, water is an electricity conductor by itself.

What do moleculers do?
water molecules are just there to difuse into other liquids to make them more dilute, or less concentrated other than that, not a lot else
Why dont the molecules from a gas particle with a speed of 1600 km per hour difuse in air at 1600 per hour?
i think it needs to be in a closed inviorment.
What happens When two solutions of unequal strength are put together with no barriers?
They will difuse into one solution of uniform strength
What is the biology of the man o war?

Where did the quote no guts no glory come from?

What is the difference between direct radiation and deffuse radiation?
*Difuse* radiation is light that reaches the surface after being reflected and scattered by clouds or other particles in the sky. Direct is that light which has not been reflected.

What does airbag trouble code 6 mean on a 1990 Mazda miata?
Means a dash sensor is mal functioning, dont worry, people with this code difuse the airbag light as it is useless and annoying, unless you are a fan of holiday lighting.
