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.
Can diffusion occur in plasma?
No, plasma is evil.
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 through a nonliving membrane?
Yes, it can.
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.
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
Where diffusion occur?
Diffusion occurs on the cell membrane.
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.
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.
What must there be for diffusion to occur?
a gradient
Does diffusion occur in plasma?
Yes.
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 happens for diffusion to occur?
two molecules must collied before diffusion happens.
Is energy required for osmoss or diffusion?
no
