Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

Osmosis using potato cores and sucrose solution 1.0 Abstract This experiment’s ultimate goal is to find the water potential of the potato cell. This was achieved through placing potato cores in different concentrations of sucrose (0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%‚ 2.0%‚ 3.0% and 4.0%) solution and to observe how much water was gained or lost through osmosis to reach a prediction of the concentration within the potato cell. The results displayed that the concentration of sucrose within the potato cell is

James Hilton’s novel Goodbye‚ Mr. Chips is the story of an English schoolmaster who dedicated his entire adult life teaching young boys. He was a somewhat shy person. Nevertheless he was a competent school teacher‚ professional and attractive in many different ways. Although his first teaching experience was not successful‚ he was determined to become a good schoolmaster. After coming to Brookfield‚ he began to warm up to his students. But more important he brought discipline to his school which

in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be net movement of water out of the potato cores. If the solution has a higher water potential than the potato cores‚ there will be net movement of water into the potato pieces. Therefore

An author can only partially structure an experience in an attempt to elicit a desired response from the reader‚ for there are two types of readers an author must consider: the implied reader and the actual reader. The implied reader is “assumed and created by the work itself” whereas‚ the actual reader brings his/her own experiences to the text and thus each reader takes away a different message from a text (MacMannus‚ para 1). Du Bois’s narrative‚ “A Mild Suggestion”‚ attempts to ensure a certain

That ’s why you don ’t need separate computers for different jobs‚ such as crunching spreadsheets or editing digital photos ➢ Disadv: For any one application‚ much of the chip ’s circuitry isn ’t needed‚ and the presence of those "wasted" circuits slows things down. Suppose‚ instead‚ that the chip ’s circuits could be tailored specifically for the problem at hand--say‚ computer-aided

The Irish potato clones were certainly low on genetic variation‚ so when the environment changed and a potato disease swept through the country in the 1840s‚ the potatoes (and the people who depended upon them) were devastated.Thesis: The Irish Potato Famine devastated the Irish population and economy as well as sowing the seeds of rebellion against England. 1st Point: Ireland dependent on potato • Families spent most time on cash crops to pay rent • Potato easy to grow‚ nutricious
