Diffusion is the process that occurs when a certain concentrated volume of material moves to a less concentrated state. Facilitated diffusion is different and is done with the help of pumps actively transporting materials across the cell membrane to create the equilibrium on both sides of the membrane.
ža specific type of passive transport
žthe movement of particles from an area of high concentration to an area of low concentration
ždissolved particles that are small or nonpolar can diffuse through the cell membrane
ždiffusion is used to reach equilibrium
–equilibrium: a condition in which the concentration of a substance is equal throughout a space

∙ 14y agoDiffusion is the main mode of passive substance transport in cells. It occurs when you have an higher concentration of Molecule A, an area of lower concentration of Molecule A, and a permeable membrane. The molecules in the area of higher concentration cross the membrane to the side of lower concentration, achieving equilibrium.
Note: Not to be confused with osmosis, the diffusion of water across a selectively permeable membrane.

What is osmosis a type of?
Diffusion. Osmosis is the diffusion of water across a membrane.Osmosis is a special type of diffusion. It is the movement of water molecules only from a solution of higher water potential to a solution of lower water potential across a selectively permeable membrane.The characters in bold indicate the specificity of osmosis as compared to diffusion.(Biology, chemistry) diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
Molecules tend to move from an area where they are more concentrated to an area where they are less concentrated This process is called?
Diffusion
What is the definition of the science term Diffusion?
"An example of diffusion in biological system is diffusion of oxygen and carbon dioxide across the alveolar-capillary membrane in mammalian lungs(biologyonline.org)." And Also, Distance of Diffusion "The shorter the distance a gas travels, faster it can reach its destination  Oxygen and carbon dioxide need help Gases are transferred to blood This speeds up their delivery to individual cells (W.W. Norton & Company, Inc. DISCOVER BIOLOGY)."
Diffusion with a channel protein?
They are the channels by which molecules enter in facilitated diffusion.
An example of passive transport process is?
Diffusion, filtration, and osmosis. Diffusion.
What are the types of diffusions?
In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
What is an example of diffusion of H2O through a DPM?
has to do with cells & diffusion biology 2 in high school
What is the purpose of facilitated diffusion?
there is no freaking purpose, Biology blows. -___-
What is the definition of diffiusion in science terms?
Diffusion in Biology is when atoms and small molecules move across the cell membrane.

What is diffusion in science terms?
In biology, diffusion is the passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration. Diffusion is the free movement of particles in a liquid or gas down a concentration gradient.
I have this biology power-point to do about diffusion can anyone help me by telling me what affects diffusion PLEASE 3?
Well diffusion is when, say an aerosal can is sprayed into the atmosphere, taking it quite a while for you to smell it than the person closer to the can. the particles (which happen to smell in an aerosal can) mix with the particles in the air and cause diffusion. Hope I helped! :)
When a cell secretes a hormone that is a form of?
In my biology class this specific questions was asked. A cell secretes a hormone through facilitated diffusion.
What is osmosis a type of?

How are diffusion and osmosis the same?
they are processes in biology. yeah.
How many types of Passive transport are there?
1) Passive diffusion. 2) Carrier mediated diffusion. In passive diffusion particles move from higher concentration to lower concentration. In carrier mediated passive diffusion a carrier protein comes, takes a paricle with it, go inside the cell membrane and liberate the particle inside. This is simple physics. By this way, once equal concentration is achieved (50 % on either side.) the diffusion should stop. But in biology the absorption may extend to very high level by passive diffusion. In biology on the other side of the cells there are cappilaries. They carry away the particle, say glucose, and maintain the concentration gradient. And so absorption continuesto very high level. ( Till all the particles are equally distributed.)
What does hierarchical diffusion mean?
If you are taking biology you know that hierarchy means order from greatest to least and diffusion means spontaneous movement of particles of any kind where they are more concentrated to less concentrated so I believe the answer would be the highest level of particles to the lowest level of particles. Do not quote me on that but it sounds about right. If you're talking about human geography hierarchical diffusion is a form of diffusion in which an idea or innovation spreads by trickling down from larger to smaller adoption units.
