Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature‚ molecular weight‚ and movement. To test the rate of diffusion a drop of dark food coloring was added to a glass of tap water and it was timed to see how long it took for the drop to reach the bottom of the glass. This procedure was repeated three

Lab Activity No. __ Diffusion and Osmosis I. Introduction Diffusion is the transfer of molecules (or ions) from an area of higher concentration to a lower concentration‚ while osmosis is the transfer of water from a higher concentration to a lower concentration. II. Objectives 1. Demonstrate diffusion and osmosis across membrane. 2. Examine the relation of membrane permeability to diffusion and osmosis. III. Materials 2 thistle tubes‚ 2 big beakers‚ 4 tube clamps to fit iron stands

close relationship or a contract with Natanz enrichment facility and that might be the start of spreading the virus. Some experts believe that it took about six month for the worm to reach its target. They believe that the form first gathered good information of the facility and a map of internal network and sent it out in the same way. Then by a trigger it starts to act. Also the action of worm was to slow down and then speed up the centrifuges by sudden to destroy the enrichment process. These facts

Joshua Annan Biology Section-04 Diffusion and Osmosis December 14‚2012 Alexis‚ Adiba‚ Elliot and Joey Purpose: The purpose of this lab is to get a better understanding of osmosis and diffusion in molecules. We will do this by studying different solutions and how they move through the permeable membrane. Hypothesis: The three different possible predictions were the lab were that the mass would stay the same‚ the mass will increase‚ or the mass will decrease

the difference between Information Systems and Information Technology? In: Computer Terminology‚ Technology‚ Information Technology [Edit categories] Answer: Information Systems is a large umbrella referring to systems designed to create‚ store‚ manipulate‚ or disseminate information. Example of an information system is a pencil and a piece of paper. The two objects themselves are just tools‚ but together they create a system for writing (information). The term Information systems has been around

AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion. Diffusion is a movement from a higher
