The effect of exercise on heart rate Word Count THE EFFECT OF EXERCISE ON HEART RATE Abstract - Aims - This study is to ascertain‚ if there is an effect on heart rate after exercise. This is being done to see‚ if there is a difference between resting heart rate and heart rate after performing exercise. Method and results - The study was compiled of seven female students from the University of Huddersfield. For the exercise a step was used‚ a polar heart rate monitor was used for

The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

The experimental samples for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls

Esterification and Hydrolysis: Methyl Benzoate by Fisher Esterification Nitration of Methyl Benzoate Jingling Li 2/16/2014 Purpose of the experiment: To understand the mechanisms for Fisher esterification reactions as an equilibrium process and hydrolysis is the reversal reaction of esterification. Nitrate methyl benzoate by an electrophilic aromatic substitution reaction. Summary of procedures: Add sulfuric acid to the mixture of benzoic and methanol‚ heat up the mixture to 65 oC

Plants contain many pigments in different proportions. For flowering plants it’s mostly a combination of chlorophyll-A‚ chlorophyll-B‚ pheophytin and Carotenes. These pigments have shades of green‚ blue green‚ grayish‚ and yellow-orange. Their concentration is different for different species and also depends on the time of year. Also‚ these pigments have different solubility in different solvents. Extracted pigments could be used in another project‚ such as chromatography. Attention! This method

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

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

enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the concentration of protease in the solution increases so it will take less time for the reaction to take place . This is because the rate of an

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two
