involves osmosis which is hypotonic‚ hypertonic and isotonic. In a hypotonic solution‚ the water will move into the cell due to the outside of the cell having a lower solute concentration than the inside of the cell. When an animal cell is placed in a hypotonic surrounding (lower solute concentration)‚ the water molecules will move into the cell causing the cell to burst and haemolysed. When plant cell is placed in a hypotonic solution‚ water molecules diffuse into the cell and the plant cells remain turgid

be discussing a potato chip company that has changed its market structure and what affects this change has made on the company‚ businesses that work with the company‚ and consumers. Prior to Wonks potato chips being in existence it was independent potato chip companies that operated in the Northwest that were ran in a competitive structure and in long-run competitive equilibrium. Once these potato chip companies were all bought up and turned into one company called Wonks potato chips which is now

Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

In the early 1800s life in Ireland wasn’t easy‚ Irish citizens got by day to day by farming and relying on the potato. The potato was their main source of food and money. With out the potato the Irish would have nothing. No one was prepared for what was about to happen in 1845‚ the beginning of the Great Irish Potato Famine. The Irish Potato Famine was the worst tragedy in the history of Ireland. The outcome of the famine would result in hundreds of thousands dead‚ an failure of the economy

do: We will put potato pieces of similar sizes in to test tubes of different concentrations of sucrose solution‚ and measure any changes in mass and length. Affecting Factors: There are a number of factors which can affect our results. We need to keep them all the same‚ and make sure that the only thing that changes is the concentration of the sucrose solution. These factors include: • Starting length of potato • Volume of Sucrose solution • Temperature of potato • Temperature

Kinetics: The Iodine Clock Jane Smith Purpose: The objective of this experiment was for students to apply their knowledge of kinetics and rate laws in order to determine the rate of a chemical reactions‚ activation energy‚ and frequency factors of those reactions. Specifically‚ this experiment was performed using a series of solutions with varying concentrations of KI‚ Na2S2O3‚ and (NH4)2S2O3 . Students recorded time elapsed to observe physical evidence of a reaction taking place in a solution. The

The light appeared out of the darkness. Neon lights from Tony´s diner across the street were flickering. It was a freezing winter night in the suburbs of New York and every now and again you could hear the homeless wondering about singing Christmas jingles with a troubled voice. Robert Pierce was sitting in his old‚ dull apartment. He stood glaring out of his only window in front of his desk. He was stuck with his endless writing. Writing was a skill Robert picked up after World War Two‚ from having

Pages 8 - 14: Main Experiment Introduction In this experiment I am going to investigate the effect of varying concentration of a differing glucose solution on the amount of osmotic activity‚ between the solution and a potato tuber of a given size. The purpose of this experiment is to demonstrate how living cells rely on osmosis‚ the diffusion of water. Osmosis is the movement of water molecules (H20) from a region in which they

Lab #3: Method of Initial Rates: Iodine Clock Introduction The detailed system of steps in a reaction is called the reaction mechanism‚ and it is one of the principal aims of chemical kinetics to obtain information to aid in the elucidation of these mechanisms in order to better understand chemical processes. Reactions usually occur in a stepwise manner with each step proceeding at a different speed. If the rate of reaction is slow enough to measure‚ this is indicative of a step much slower
