membrane, which remains permeable to water but impermeable to the solute materials, meaning that they cannot cross through it. Diffusion and osmosis differ in this way, as diffusion describes the movement of the solutes through a solvent, while osmosis describes the movement of the solvent itself....
Diffusion can be used as a type of transport by cells but is roughly defined as the movement of molecules through a semi-permeable membrane. This movement is in one particular direction. Answer and Explanation: Diffusion is the movement of molecules through a semi-permeable mem...
Stable diffusion is a term that describes the movement of molecules from an area of high concentration to an area of low concentration in a steady and consistent manner. Imagine you have a balloon full of water and you poke a tiny hole in it. The water will slowly leak out of the hole...
Provide the most appropriate term that describes the following definition or statement: The net movement of molecules down a concentration gradient. Define adaptions. Give a definition of a gamete. Define the term "gel". What is the meaning of the term biology?
One example of stable diffusion is Brownian motion, which describes the random movement of small particles suspended in a fluid or gas. In this case, individual particles move in a zigzag pattern due to collisions with other molecules in the medium. Another example is Fick's law of diffusion,...
Movement of particles from an area of higher concentration to lower concentration. Oxygen diffusing from the lungs into the bloodstream. 3 Effusion Involves movement from high pressure to low pressure or vacuum. Gas escaping into a vacuum chamber through a small orifice. 4 Diffusion Driven by the...
Einstein wrote later that his major aim was to find facts that would guarantee as much as possible the existence ofatomsof definite size. In the midst of this work, he discovered that according toatomic theorythere would have to be an observable movement of suspended microscopic particles. Einst...
The diffusion equation describes the flow of particles, waves and energy from neutrons, electrical charge, molecules and microscopic particles to light, sound, and heat1,2,3,4. The diffusion model begins with the assumption that scattering is local—the velocity, v, is randomized within a distan...
Downward molecular diffusion, as indicated by the name, can be described as a randomly occurring process caused by natural air currents and eddies that promote and enhance the downward movement of airborne particulates (Figure 5.7). These random movements exist even in relatively still air and tend...
Osmosis is the movement of water through a selectively permeable membrane due to difference in: a. pressure potential b. sugar c. plasmolysis d. solute concentrations Explain simple diffusion, facilitated diffusion, and osmosis. What is the difference between osmosis and diffusion? a....
