1) Irish Potato Famine. 1845-1849. Called the Great Famine. In the early 19th century‚ Ireland’s tenant farmers struggled to provide for themselves and to supply the British market with cereal crops. By the early 1840s half the Irish population‚ mostly the rural poor‚ became to depend almost exclusively on the potato for their diet. The rest of the population also consumed it in large quantities. A heavy reliance on just one or two high-yielding types of potato greatly reduced the

The Irish Potato Famine was a great famine that took place in Ireland between 1845 and 1852. The famine was caused by a potato disease‚ also called a potato blight. This was a huge problem especially considering that much of Ireland’s population was heavily reliant on potato crops. The famine itself killed around one million people. The question of genocide comes in when the British are taken into account. Ireland was dependent to Britain‚ much like how today countries like Puerto Rico are dependent

In this enzyme lab‚ (insert creative name)‚ the enzyme catalase was observed under varying conditions in order to interpret what prohibits and inhibits the functioning of certain enzymes in chemical reactions. Enzymes aid in chemical reactions by speeding up the time it takes for the reaction to occur‚ without getting “used up” throughout the process. Catalase‚ the specific enzyme used in this lab‚ is a protein abundant in the liver and red blood cells. It enhances the breakdown of hydrogen peroxide

However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or

BUSINESS ETHICS: REFLECTION PAPER 1 HELP THE RICH‚ HURT THE POOR The controversy regarding the SEZs in India has turned the issue into what is commonly known as a “hot potato”. The heated debate today is whether these SEZs are good for India or a hotbed for disaster that is going to spell long term doom for the nation. Like many things that go wrong in a nation like India‚ the SEZs too failed in the implementation phase. Arable land has been used to set up industries‚ farmers have been displaced

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;
