THE IRISH POTATO FAMINE Pre-Famine History The potato was introduced to Europe sometime in the 16th century. There are many theories on how it arrived‚ but the one with the most credibility is from a case study done by Theresa Purcell. She explains how the white potato‚ also known as the Irish potato‚ originated in the Andean Mountains and was brought to Europe by the Spaniards. The potato was originally classified in the same family as the poisonous nightshade so people refrained from eating

Osmosis was clearly shown since the potato cylinders decreased or increased at different concentrations of sucrose. The results supported my hypothesis because for the 0.0 sucrose concentration the average percent change in mass was 16.9%. For the 0.2 concentration the percent change was 3

foam that can be measured. ANALYSIS QUESTIONS 1. a) Describe the effect of damaging the potato on the catalase activity. With the increased level of damage to the potato‚ there appeared to be more activity within the reaction between the catalase and the H2O2. b) Explain at the cell level why crushing or macerating the potato has this effect. When you crush or macerate the potato‚ you are breaking the cell walls of each individual cell. Once this happens‚ the catalase is

Title: Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1. Concentration of sucrose solution table Concentration/ M | Sucrose Solution/ ml | Distilled

Battery from Potato Introduction: Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used to generate

Psychology Experiment No. 2 Effect of Inconsistency of Objects in Scenario on Perception Introduction: In our everyday lives‚ we are used to seeing objects within their particular characteristic scenarios. For example‚ it is nothing to wonder if we see a person browsing the internet in a computer lab or a car speeding on a road. However‚ when we see an object which is inconsistent with the environmental setting‚ we do feel alarmed. Thus‚ it is shocking for us to see someone working on a
