As long as there is a concentration gradient. This is because diffusion occurs which is the net movement of substances from a region of high concentration to a region of low concentration.

Movement across a concentration gradient occurs until equilibrium is reached, where the concentration of a substance is the same on both sides of the gradient. The rate of movement depends on factors such as the size of the gradient, temperature, and properties of the substance.

How can active transport differ from passive transport?
Active transport can occur against a diffusion gradient ("uphill flow).
What kind of energy does diffusion use?
Diffusion is a passive process that uses kinetic energy from the random movement of particles to spread substances from an area of high concentration to an area of low concentration. No external energy input is required for diffusion to occur.
What must occur to electric current?
transfer/movement of electrons
How wind affect the rate of evaporation?
Wind can increase the rate of evaporation by removing the layer of moist air that sits atop the water surface, allowing for more water molecules to escape from the liquid to the gas phase. The movement of air also helps to maintain a concentration gradient, decreasing the buildup of water vapor near the water surface and allowing for continuous evaporation to occur.
What causes an electrical flash over?
An electrical flashover is caused by the breakdown of air insulation between two conductors due to a high voltage gradient across them. This breakdown can create a sudden, visible discharge of electricity between the conductors, resulting in the flashover. It can occur due to factors such as contamination, improper spacing, or excessive voltage.
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.
Would the passive movement of substances occur if the interstitial solute concentration was the same as the filtrate solute concentration?
No. Solutes move down their concentration gradient, from areas of high concentration to areas of lower concentration.
Does isotonic solution cause osmosis?
Yes, isotonic solutions do not cause osmosis to occur as they have the same concentration of solutes as the cell, resulting in no net movement of water across the cell membrane. Osmosis only occurs when there is a concentration gradient that drives the movement of water from an area of low solute concentration to an area of high solute concentration.
What isThe difference in concentration between a region of high concentration and one of lower concentration?
Regarded as existing through Space, or Time, or from one end of an aqueous Solution to the 'other'; these differences are seen to occur across a GRADIENT. In other related circumstances we are talking about a Spectrum.
How diffusion will occur?
diffusion is occur when different concentration gradient is applied
Difference between osmosis and diffusion?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, resulting in equal distribution of molecules. In short, osmosis specifically refers to the movement of water molecules, while diffusion can involve any type of molecule.
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
For diffusion to occur there must be?
a concentration gradient, with a higher concentration of particles in one area than another. This difference causes particles to move from an area of high concentration to an area of low concentration, allowing for diffusion to occur.
What is the similarities between osmosis and diffusion?
They both follow the concentration gradient i.e. require no energy for the process to occur. Diffusion is the movement of particles from an area of higher concentration to lower concentration. See Brownian motion. Osmosis is the movement of WATER particles across a semi-permeable membrane from an area of higher concentration to the lower concentration in the effort to reduce the solute concentration.
How does osmosis occur?
Osmosis occurs when water molecules move from an area of high concentration to an area of low concentration through a semi-permeable membrane. This movement is driven by the concentration gradient of water molecules across the membrane. Osmosis is essential for maintaining the balance of water and solutes in cells and tissues.
What is the differece between passive and active transport?
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.
What is is required for diffusion to occur?
A concentration gradient and a (semi-)permeable membrane.
