    CONCENTRATION OF GLUCOSE ON POTATO STRIPS INTRODUCTION: Molecules of liquid and gas are constantly in motion‚ they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move‚ they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called Diffusion‚ for example smell of cooking travelling around the house from the kitchen‚ circulation of oxygen from the alveolar air

    1. Provide 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

    uses diffusion as an important transport process through its selectively permeable membrane. During diffusion‚ molecules that are small enough to pass through a membrane’s pores or molecules that can dissolve in the lipid section of a membrane move from an area of higher concentration to an area of lower concentration. The kinetic energy that all molecules possess is the motivating force in diffusion. Facilitated diffusion occurs when molecules are too large to pass through a membrane or are lipid

    The Importance of Orders. What would the military be without rules and regulations to follow? A brief answer would be that every man and woman in the service would be considered just another civilian but with guns doing whatever they wanted and going to war with whoever they wanted without any consequences. Our military services are highly honored for the obedience they set in stone throughout all the service men and women. Obedience goes beyond listening to the commanding officer‚ it also involves

    rate of respiration. I am going to change the concentration of the glucose solution and I’m going to measure the volume of gas produced during respiration in cm³. Yeast contains enzymes. Enzymes speed up a chemical reaction – they’re biological catalysts. Yeast can respire both aerobically and anaerobic; the anaerobic respiration of yeast is known as fermentation. The equation for this type of respiration in yeast is: Glucose Carbon Dioxide + Ethanol The presence of ethanol means that yeast

    Experiment 3: Cryoscopic Determination of Molecular Weight Aim: The primary objective of the experiment is to calculate the total molecular mass of the compound benzoic acid in a predetermined amount of cyclohexane. Introduction: One of the key concepts in this experiment is the term freezing point depression. The definition of this phrase is that when a solute is dissolved into a solvent‚ their collective boiling point will be less than that of the original boiling point of the solvent. This incidentally

    Perhaps one of the biggest blocks of foundation for the military is the ability to lead and follow orders. Without the will to follow‚ soldiers would do as they will‚ not what they are told to do. When people are told what they need to do it is usually by someone that has experience in whatever field they may be in‚ if they fail to follow those simple orders given to them chaos can erupt by lack of communication and possibly failure to get the mission done. The US army is one of the oldest groups
