None. The molecules were either too polar or they were too big to be transported.

What solute's passed through the 100 MWCO membrane?
using a 100 MWCO membrane means that any element, molecule, ion or particle with a molar mass of less than or equal to 100 will be able to pass through. there is an infinite number of combinations able to pass through. sodium and calcium ions would both pass through for example.
Are solutes always able to diffuse through a cell's selective permeable membrane?
No, cell membranes are semi-permeable, meaning they allow some solutes to pass through - but not others.
What do transport dos?
Transport proteins help move (or "transport") large molecules that aren't able to pass through a cell's membrane, through said cell membrane through means of diffusion.
The neuron's cell membrane permits some substances to pass through but not others this is because the membrane is?
One of the characteristics of a cell membrane is that it is semi-permeable. As such, it is able to limit what can get into and out of the cell.
Why aren't protons able to diffuse through the inner mitochondrial membrane?
Its going against their gradient
The degree in which materials are able to flow freely through a cells membrane is known as?
study island : permibility
How are the smaller molecules o2 and co2 able to pass through the openings of the cell membrane?
passive transport by diffusion
True or false The cell membrane is selectively permeable?
True. Permeable means that things are able to pass through something, and selective indicates that certain things are able to pass through.
Why do solid lack property of diffusion?
The molecules are too tightly bound to one another to be able to move about separately and get through a membrane.
Which term refers to the diffusion of water molecules through a slestively permaeable membrane?
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
What structures allow large important molecules to pass through the cell membrane?
A cell membrane is in every plant and animal and it lets in water, nutrients, and food to the cell. The membrane MUST be permeable because then it wouldn't of let the in water, nutrients, and food into the cell. If the membrane was stiff, the molecules of water, nutrients, and food would not be able to fit into the cell.
What do water passes through a membrane by?
It's called osmosis. The water will travel across the membrane to equal out concentrations so they are both the same. This is because water is a small molecule, able to move through the membrane.Think of it this way. If there were no membrane then the dissolved substance would diffuse throughout the mixture. If you put a membrane there then the same idea works but this time it is only the water that can move. So the water moves through the membrane until the same concentration of water molecules appear on each side.
