Can diffusion occur through a nonliving membrane?
Yes, it can.
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
When does diffusion occur across a cell membrane?
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
What is is required for diffusion to occur?
A concentration gradient and a (semi-)permeable membrane.
What part of an animal cell allows diffusion and osmsis occur?
the cell membrane
Can osmosis occur in the absence of menbrane?
Osmosis is a type of diffusion that occurs with a semi permeable membrane. It can therefore not occur without a membrane because that is what differentiates it from diffusion.
Where diffusion occur?
Diffusion occurs on the cell membrane.
Can diffusion occur without membrane?
Diffusion is the movement of molecules kineticly from an area of high concentration to an area of low concentration until they are evenly distributed. Osmosis is the movement of molecules thru a membrane.

Can osmosis and diffusion can both occur at the same time through a dialysis membrane?
no
What part of an animal cell allows diffusion and osmsis occur?
the cell membrane
What is essential for diffusion?
A- A Concentration Gradient B- A Selectively Permeable Membrane C- A Source of Energy D- A Protein The Answer Is (A) Diffusion can occur without a semipermeable membrane, as diffusion is simply movement of a substance from high to low concentration. A source of energy is needed only for active transport. Proteins are needed if the the particles transported are too big to pass the semipermeable membrane.
Difference between osmosis and diffusion?
Diffusion is the movement of substance (anything- solid ,liquid, gas, etc.) from a higher concentration gradient to a lower concentration gradient.Osmosis is the net movement of water molecules from higher concentration gradient to a lower concentration gradient through a partially permeable membraneSo the difference is that diffusion involves movement of any particles/ substance (e.g. solid, liquid, gas) while osmosis can only occur with water.Another one is that diffusion can occur with or without a membrane but osmosis can only occur with a membrane.Hope this helps. :)
What doesn't occur as a cell grows larger in size?
Diffusion across the cell membrane is impaired
