How the Potato Changed the World In today’s world the potato is the fifth most vital crop universal‚ it follows wheat‚ corn‚ rice and sugar cane. However in the 18th century the potato was an amazing novelty‚ part of a global environmental fit started by Christopher Columbus. Roughly 250 million years ago‚ the world consisted of a single giant landmass now known as Pangaea. Physical forces broke Pangaea separately‚ creating the continents and hemispheres well-known today. Over the eons

DNA Structure Monday‚ 15 April 2013 9:01 AM - DNA = Deoxyribonucleic acid DNA is a double-helix: it has two strands that twist around each other Each strand is made of single units call nucleotides It has a sugar-phosphate backbone Bases join the two strands by hydrogen bonds ○ These bases are cytosine‚ guanine‚ adenine and thymine. - Complementary base pairing is a key idea in genetics: C pairs with G‚ and T pairs with A. - Each strand of DNA can be millions of base pairs in length and is

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

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

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

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

Investigating the Water Potential Of Potato Cells Aims 1. To test how water potential‚ in a solution‚ affects the movement of water in and out of a cell by osmosis Prediction I predict that by increasing the water potential around the outside of the potato cell‚ (i.e. so that the water potential is greater outside the cell compared to the inside of the cell e.g. 0m sucrose) that the net movement of water into the cell will increase. This is due to the water potential being greater outside the cell

Reetika Kashyap September 20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that
