My group and I are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads

transitions from being an embryo in a seed to breaking out and becoming a little stem. There are many factors that affect the germination of seeds which include the PH level of the soil‚ the amount of water in its environment‚ the amount of ATP the seed can generate in order to grow‚ the temperature of the environment and the amount of sunlight the seed receives (Ghaderi-Far et al.‚ 2010). The purpose of this study was to observe the effect of different concentrations of sodium chloride have on the

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

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

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

A 500 word essaying on following orders. What is the purpose of following orders or more relevantly why does a solider follow orders. Besides the obvious reasons of: avoiding getting yelled at‚ smoked or counseled. A solider follows orders to get the task at hand done. This ultimately leads to increased mission effectiveness and/or mission success. If a solider fails to accomplish an order‚ fails to follow an order or even out right refuses to listen to the order‚ any and all missions or
