Simple Experiments on the Enzyme Catalase Aim: The aim of this practical is to use three different techniques to investigate the effect of different concentrations of the enzyme catalase on the rate of breakdown of hydrogen peroxide. Background information Catalase is an enzyme which is found in all living organisms. This enzyme catalases the decomposition of hydrogen peroxide into water and oxygen. Cells continually produce a poisonous by-product of metabolising‚ called hydrogen peroxide. This

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

you must be able to understand what the poet is trying to reveal to you. Luckily I understood very well what the poet was trying to communicate when I read “egg horror poem”‚ by Laurel Winter. I believe that Winter wanted to make the reader feel as if they were one of the eggs‚ feeling all of the suspenseful emotions that come with being an egg‚ she does this by using imagery words‚ voice‚ and her ideas. This involves making me feel like I am waiting in a carton with my friends‚ waiting for the fridge

again. FLOATING EGG MATERIALS: 3 eggs Water Salt 3 glasses Spoon PROCEDURE: 1. Pour the first glass of water and put the egg. 2. Pour the second glass of water and mixed it with a spoon of salt. After that put the egg. 3. Pour the third glass of water anf mixed it with a spoon of salt and after that put the egg. After putting the egg pour some water on the glass. REFLECTION: When we put the egg on the first glass it didnt float but in the second glass the egg floated and it is because

EGG DROP PROJECT Using principles of physics‚ design and construct a container for a raw egg that can be dropped from the second story balcony of St. Joseph’s Academy and strike the ground without breaking the egg. The finished container must meet the following criteria: No professional packing materials (such as bubble wrap or Styrofoam peanuts) may be used. The egg must be raw and either Large or X-Large. If a parachute is attached to the container‚ it must be made from

Emily Martin: The Egg and the Sperm It is human nature to place confidence into science because it is heavily researched and perceived as the truth. However‚ Emily Martin shows that the female role in the reproductive process is not thoroughly depicted. Martin said‚ “part of my goal in writing this article is to shine a bright light on the gender stereotypes hidden within the scientific language of biology.” This article demonstrates how the female role in the reproductive cycle is just as insistent

THE EFFECT OF INCREASING THE CONCENTRATION OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI Background: Escherichia coli are rod shaped‚ gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo‚ 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans‚ however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown‚ 2012). The active ingredient in Dettol

East Egg versus West Egg East Egg and West Egg are "identical in contour and separated only by a courtesy bay ... They are not perfect ovals ... but their physical resemblance must be a source of perpetual wonder to the gulls that fly overhead. To the wingless a more interesting phenomenon is their dissimilarity in every particular except shape and size."(9) In The Great Gatsby‚ F. Scott Fitzgerald creates different worlds‚ where many different people live amongst each other. The areas of

lost all control over each other and even themselves because they forgot where they came from and what they stand for. The three main stages of societal deterioration seen in The Lord Of The Flies are the failure to duplicate British society‚ the breakdown of society into two factions‚ and finally the act of murder. The initial stage of societal deterioration seen in The Lord Of The Flies is the boys’ inability to effectively duplicate British society. The first time this can be seen in during one
