object or evaluation. This report aims to conclude whether there is a difference between female and male attitudes towards smoking. It is hypothesised that females will have a more positive attitude towards smoking. Questionnaires using a 5 point likert scale will be utilised to measure each participants’ attitude towards smoking through their responses. Results stated there is no significant difference between genders when scores were placed through an independent t-test. It is concluded that more

are many conditions of the environment that can affect the optimum operation of enzymes. These condition include temperature‚ enzyme concentration‚ substrate concentration‚ acidity‚ salinity‚ and any present activators/inhibitors. In this particular lab‚ temperature was the environmental factor studied. More specifically‚ the enzyme catalase and its substrate hydrogen peroxide were tested under different temperatures. It was discovered that‚ temperature can affect the optimum operation of enzymes;

9-19-13 Dehydrating and Rehydrating a Hydrate Introduction The mass percent of water was determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample

As the test was conducted‚ the study shows that the difference between lacking an antibiotic and containing one is not different. An antibiotic in culture-A and culture-B does not affect the number of yielded yeast cells. Introduction. -- It is undetermined whether or not antibiotics effect yeast cells reproduction. It has been hypothesized that antibiotics decrease

To begin this test‚ 3 water baths were set up. One bath was cooled to 0 degrees celsius‚ one was heated to 37 degrees celsius‚ and one was boiled to 100 degrees celsius. 1 of the four test tubes containing 2 ml of 100 units/ml catalase was put in to each of the three water baths‚ one at a time. While the tubes sat in the baths‚ the 4 H2O2 vials were prepared and the depth of the H2O2 was recorded. After the 0 degree celsius test tube incubated in it’s bath‚ it was taken

Stoichiometry I. Introduction/ Purpose: Stoichiometry is the study of the quantitative‚ or measurable‚ relationships that exist in chemical formulas and also chemical reactions. The calculations of a stoichiometry problem depend upon balanced chemical equations. The coefficients of the balanced equations indicate the molar ratio of the reactants and products taking part in the reaction. There are three major categories of stoichiometry problems such as mass-mass‚ mass-volume‚ and volume-volume
