According to your drawings‚ in which cell (potato) did the iodine diffuse all the way to the center of the cube? Discuss the differences between the cells 5. Based on your understanding of cell size and the rate (speed) of diffusion‚explain why there are NO GIANT CELLS! Discuss diffusion in your answer. Conclusion: Restate your Hypothesis and state whether or not if it is correct and why. Refer to your data and give numbers.

F1-F4: Emulsion Solvent Diffusion Method (ESD) The microparticles of formulations from F1-F4 which are prepared by ESD method were irregularly spherical in shape. The percentage yield increased with increase in polymer concentration from 88.3 to 93.6%. Stirring speed does not show any valid effect in the percentage of yield. Particle size increased with increase in the polymer concentration due to the viscosity character of the polymer which comes in contact with the drug to form microparticles

Introduction: Because all molecules have kinetic energy and are constantly in motion cells go through a process called diffusion. Diffusion is the movement if molecules from an area of higher concentration to and area of lower concentration. This process with continue to occur until an equilibrium is reached. Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of water through a permeable membrane. The phrase “permeable membrane” means that the membrane will only allow specific

cultural diffusion‚ the limitation of spatial interaction‚ and space-time compression? Whilst reading “Globalization in a Bottle” and “The Tipping Point-- Three Rules of Epidemics” three key concepts of “Chapter One: Basic Concepts” become inherently apparent: cultural diffusion‚ the limitation of spatial interaction‚ and space-time compression. The two articles clearly depict these three theories‚ through their choice use of real world examples. In each of these articles‚ cultural diffusion is a

Title: Diffusion Rate of Methylene Blue on Agar Plates at Different Temperatures Abstract: Diffusion is the movement of particles from an area of high concentration to an area of low concentration wherein substances are independent‚ rapid and in random motion which frequently collide with each other in the sides of the container. This study aimed to assess the influence of temperature on the diffusion rate of methylene blue on agar plates. To determine the relationship between the two variables

the aim and background information 2.1. Diffusion is the spontaneous kinetic movement by which molecules move from an area of a high concentration to an area of low concentration. Diffusion continues until it reaches equilibrium. Osmosis is similar to Diffusion but it’s the process in which water moves across a semi-permeable membrane and goes to the higher concentration of solute.1 2.2. Important factors to Osmosis and Diffusion include Temperature‚ Concentration and Surface area

results. My hypothesis was ‘as the surface-area-to-volume ratio decreases the diffusion rate increases’ my results support my hypothesis‚ because in my table of results when the surface area to volume ratio is at 14 the diffusion time is 38 seconds‚ then the ratio goes down to 9‚ and the time increases to 90 seconds. My graph also supports my hypothesis‚ because the curve on my graph slopes down which shows as the diffusion time increases the ratio decreases. One of my results that could possibly have
