initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over

Title: Erythrocyte Sedimentation Rate (ESR) Aim: To measure the erythrocyte sedimentation rate of a patient to see if there could be anything wrong. Introduction: The erythrocyte sedimentation rate (ESR) is the distance that the red blood cells sediment in a specific time interval. ESR is an easy‚ inexpensive and non-specific test that is used to help protect conditions associated with acute and chronic inflammation including infections‚ cancers and autoimmune diseases. ESR is said to be non-specific

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the

VARIABLE-RATE PREFERRED STOCK Preferred stock has frequently been issued in connection with mergers and acquisitions. Often the preferred stock is issued with a conversion feature‚ so in the long run there is a probability it will become common stock capital. Preferred stock allows the acquired firm’s owners a prior claim relative to common stock and reasonably definite dividends while simultaneously giving the acquiring firm a form of leverage without strapping it with the rigid obligations of

IN T R O DU CT I ON The term Literacy is defined as the ability to read and write or in other words the ability to use a language for reading‚ writing‚ listening and speaking. In Pakistan the literacy rate is very low; First of all literacy is defined here as the people over 15 years of age who can read and write. According to 2005 estimate 54% percent of the population is literature‚ 63 percent of which are male and the remaining female. Literacy:definition:

Do you get the exact same results each time? How do the results compare to each other and to your prediction? What factors might contribute to susceptibility to the disease? 2. If the contagion rate is calculated as the number of new cases per day per total population‚ what would the average contagion rate be for Kold? Unlike some of the other interactive labs‚ this model has some randomness built in to reflect the real spread of a disease‚ which is a matter of probabilities. Despite this variability

Science Coursework-Rates of Reactions Introduction Investigating how the concentration of sodium-thiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise‚ reliable and accurate. Strategy According to my results‚ as the concentration of STS solution increased the rate of reaction of my experiment was increased. Also as the concentration
