A concentration gradient and a (semi-)permeable membrane.
What else can I help you with?
Why is energy required in passive transport to occur?
Energy is not required for passive transport to occur. Passive transport processes such as diffusion and osmosis rely on the inherent kinetic energy of molecules to move from an area of high concentration to an area of low concentration without the need for external energy input.
The more soluble and diffusible a gas is the lower the pressure gradient required for diffusion to occur?
Yes, that's correct. A more soluble and diffusible gas can move more easily across a membrane due to its increased ability to dissolve and diffuse through the barrier, reducing the pressure gradient needed for diffusion to occur.
Can diffusion occur in plasma?
No, plasma is evil.
For diffusion to occur there must be?
For diffusion to occur there needs to be a concentration gradient. Which means that the concentrations on the two sides must be different. In diffusion the particles flow from high concentration to low concentration.
Can diffusion occur through a nonliving membrane?
Yes, it can.
Does diffusion require the cell to respire?
Diffusion is a form of passive transport, so nothing is required for it to occur.
How diffusion will occur?
diffusion is occur when different concentration gradient is applied
What is the difffrence between diffusion and osmosis?
1 diff. Semi permiable membrane is required in osmosis while it is not required in diffusion. 2 diff. Osmosis cn occur only in liquid medium while diffusion cn occur in all mediums.
Where diffusion occur?
Diffusion occurs on the cell membrane.
WHEn does diffusion occur?
Diffusion is quicker at high temperatures and pressures.
Why do gases show the property of diffusion?
Diffusion occur in all phases.
Does diffusion occur in the digestive system?
Diffusion occurs when something something something
What don't the cells need for diffusion to occur?
Cells don't need to use any ENEGRY for diffusion particles to occur/happen
What must there be for diffusion to occur?
a gradient
Does diffusion occur in plasma?
Yes.
