a gradual change in the concentration of solutes in a solution as a function of distance through a solution. 2. the gradual difference in the concentration of solutes in a solution between two regions. In Biology, a gradient results from an unequal distribution of ions across the cell membrane. When this happens, solutes move along a concentration gradient. This kind of movement is called diffusion.

∙ 13y agoit is when gas particles move from a higher concentration gradient to a lower concentration gradient . for example: in the alveolus oxygen diffuses into the blood capillaries from the alveolus because there is more oxygen in the alveolus compared to the blood capillaries. andkind of like diffusion

Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
Is diffusion quicker when there is a higher concentration gradient?
yes cause the more concentration the quicker
Solutes move down a concentration gradient in?
facilitated diffusion
What is the term for the Diffusion of water across the concentration gradient?
Osmosis
How does diffusion occur most rapidly- with or against the concentration gradient?
Diffusion only occurs down a concentration gradient. Put a drop of food coloring in a glass of water - you will never see the food coloring spontaneously concentrate. It will always spread down the gradient.
Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
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
Diffusion continues until there is no?
Concentration gradient. After there's no concentration gradient, equilibrium occurs, which means no more diffusion.
What must there be for diffusion to occur?
a gradient
Concentration gradient has to do with diffusion?
Yes it does.
How diffusion will occur?
diffusion is occur when different concentration gradient is applied
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.
What is A true statement about diffusion?
The greater the concentration gradient, the faster the rate of diffusion.
What is true statements about diffusion?
The greater the concentration gradient, the faster the rate of diffusion.
Define term gradient give definition of fick's law?
Fick's laws of diffusion describe diffusion and can be used to solve for the diffusion, the concentration gradient (spatial derivative), or in simplistic terms the concept.
What is an example of diffusion in a sentence?
The rate of diffusion is determined by the permeability of the membrane and the concentration gradient.
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
