higher concentration ( hypertonic ) to a region of lower concentration ( hypotonic solution ) through a cell membrane or other semi-permeable membrane until an equilibrium is reached. It is a special case of diffusion called “ passive transport “ which means no energy is required. Diffusion is the movement of a substance by which the molecules move from a region of higher concentration to a region of lower concentration. Aim Our aim of the experiment was to observe and investigate the process

Diffusion Experiment: Osmosis in Sucrose Solutions Abstract We used dialysis tubing to simulate a semi-permeable membrane. Since molecules diffuse from their higher concentration to their lower concentration‚ water will move across the membrane in response to this concentration. While conducting this lab we were able to observe passive transport through diffusion and osmosis. Introduction Osmosis is a specialized case of diffusion that involves the passive transport of water. When

Ratio decidendi and obiter dicta Learning objectives At the end of this module‚ you will be able to: * distinguish between ratio decidendi and obiter dicta. * apply well-established rules to identify the ratio decidendi in a decision. This module is intended as a useful exercise in revision. If you are certain that you understand how to discover the ratio in an opinion‚ you should skim lightly over this material. What is the ratio decidendi? As you probably recall from your studies

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

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy
