1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1

of new ideas‚ media‚ etc History and Orientation Diffusion research goes one step further than two-step flow theory. The original diffusion research was done as early as 1903 by the French sociologist Gabriel Tarde who plotted the original S-shaped diffusion curve. Tardes’ 1903 S-shaped curve is of current importance because "most innovations have an S-shaped rate of adoption" (Rogers‚ 1995). Core Assumptions and Statements Core: Diffusion research centers on the conditions which increase or

The things that count account for this difference between systolic pressure when the sound began‚ the stethoscope user heard it‚ and the computer operator pressed the event marker keystroke is because how fast sound travels. This comes into play because first the person using the stethoscope uses it‚ and he/she is not going to be able to react immediately to inform the computer user. There is a delay when the stethoscope user hears it from when the first sound begins‚ and then there is a delay when

Have you ever heard of Net Neutrality? Net Neutrality is the principle that internet user have access to all contents on the internet regarding the source without blocking for a fee. This means the internet is free to use and you don’t have to pay to use a certain amount of websites you need‚ unlike cable where you have to pay for a package with 60 shows when you only use about 15 or 10 shows. But there has been some events where people have used company products and bootlegged them to where people

Diffusion and Osmosis Diffusion -the process by which molecules spread from areas of high concentratiion‚ to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM DIFFUSION Concentration gradient - a difference between concentrations in a space. Molecules will always move down the concentration gradient‚ toward areas of lesser concentration. Think of food coloring that spreads out in a glass of water‚ or air freshener sprayed in a room
