remained in power by taking away the Irish people’s land and reallocating it to Scottish farmers. The United Kingdom of Great Britain and Ireland was formed in 1801. The Irish people were upset by this and did not want to lose their independence. The Potato Famine that lasted from 1845 to 1848 took its toll on the population of Ireland‚ which went from 9 million to 3 million. The famine oppressed the undernourished people‚ yet Britain failed to offer sufficient support. Gladstone became the Prime Minister

EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT 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

Mass % of Sucrose in Chewing Gum Purpose To find the mass percentage of sucrose in chewing gum and compare the actual mass to the mass indicated on the package and compare the masses to that of different brands of chewing gum. Hypothesis The theoretical mass percentage of sucrose (C12H22O11) in chewing gum. Materials - Sample of chewing gum + wrapper - Electronic balance Procedure 1. Form groups of 3‚ and distribute a different brand of gum to each member of the group. 2. Record the brand

Ireland suffered greatly during the potato famine in the 1840s. Around one million people died of starvation or disease. Many immigrated to the United States to try to escape the horrid that surrounded them in Ireland.Food was considered the most deadly weapon in a war. Starvation was the leading cause of death in a war. If you had control of the food supply‚ your army had the greater advantage. Your enemies would most likely fall from starvation‚ enviably you would win. Food also gave the soldiers

Q-1 A surgeon wish to predict the live or death (status) of a CABG patient through their pulse rate‚ systolic blood pressure‚ sugar level‚ hemoglobin etc. He got the data from last 1600 surgeries held in a local hospital and applied an analysis. He got the following result Identification: It is binary logistic regression (LOIGT) Coding 0 = Death 1 = Alive The two post-operative status of the patients are death and alive coded by 0 and 1 respectively to use in binary logistic regression.

Introduction: The objective of this experiment is to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this

The Process of Osmosis and its Importance to Living Organisms. Osmosis is the diffusion of water through a semipermeable membrane that does not allow dissolved solids (solutes) to pass. Osmosis refers only to diffusion of water and the direction of movement is from the area of higher concentration to the area of lower concentration. This migration of water from a region of higher concentration to a region of lower concentration is spontaneous and although water molecules move in both directions

The effect of salt concentrations on the mass of the pear cubes ‘Pyrus’ after being soaked in water Aim: The effect of salt concentrations on the mass of the pear ‘Pyrus’ pieces shaped as cubes of 1cm. Background: Osmosis is the net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential. Water makes up to 70-90% of living cells and cell membranes are partially permeable membranes. Dissolved substances attract

Effect of Osmosis on Egg Introduction: The purpose of this lab was to test the effects of hypertonic‚ isotonic‚ and hypotonic environments on the weight of a shell-less egg. We tested the weight of the egg after thirty minutes in water as well as corn syrup. I hypothesized that when the egg was placed in water‚ it would swell and gain weight because it was in a hypotonic environment. That hypothesis was correct as the egg grew slightly and the weight when up. I also hypothesised that when the egg
