Austin Vandermey GS-1140 April 4th‚ 2015 Experiment We as a society have one big problem on our hands. This problem is sleep deprivation because there are not enough hours in the day to get stuff done. Between work‚ school‚ family‚ and leisure it seems like we do not have enough time to get are daily tasks done let alone have time for sleep. It is recommended by the U.S Department of Health that people need a solid eight hours of sleep to maintain good health. I don’t know about you

Ideal Temperature for junket Aim- To discover the optimum temperature for junket to solidify Hypothesis- That the optimum temperature will be between 35-40°C Independent variable- Temperature (10‚ 40‚ 60 degrees) Dependant variable- Time taken for Junket to set Control- 2 clearly marker test tubes will be placed under each temperature condition‚ one with junket and one without‚ to clear the complication that it might be the temperature that is reacting with the milk and solidifying it instead

Wissam Bardouh HSC BIOLOGY ASSESSMENT TASK 1 MAINTAINING A BALANCE TASK: OPEN-ENDED INVESTIGATION Our task is to plan‚ choose equipment and perform a first hand investigation to demonstrate the effect of dissolved carbon dioxide on the pH of water. DUE DATE: 21/11/07 CONDUCTOR: Wissam Bardouh EFFECT OF DISSOLVED CARBON DIOXIDE (CO2) ON PH OF WATER Introduction: ((Carbon Dioxide is a greenhouse gas. It is everywhere ranging from our bodies to the atmosphere. Carbon dioxide is produced in living

Biology A - Assignment 1: Cell Membranes and Temperature Background Theory Beetroot contains betalain pigments within it’s vacuole‚ which gives it it’s purple-red colour‚ it’s this pigment which leaks out as the beetroot is heated and the cells membrane begins to break down. The practicals aim is to show the effect of temperature on the cell membrane by observing the colour change of the water the beetroot was placed in. The cell membrane is important as it controls the substances enters and

Environmental Variables and their effect on Horseradish Peroxidase Abstract There are several factors that can affect the rate of reaction of peroxidase such as temperature‚ pH‚ concentration of peroxidase present and whether or not it has been boiled. Our experimental data demonstrated that peroxidase activity peaked between 23 degrees Celsius and 32 degrees Celsius. We found the pH to be 7 for optimal activity. As far as the concentration is concerned our results showed that as the concentration

the climate of a region is an important factor in determining which organisms can survive there. Even within a biome‚ precise conditions of temperature and precipitation can vary over small distances. Ecologists recognize at least ten different biomes. The world’s major biomes include tropical rain forest‚ tropical dry forest‚ tropical savanna‚ desert‚ temperature grassland‚ temperate woodland and shrub land‚ temperate forest‚ northwestern coniferous forest‚ boreal forest‚ and tundra.

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration

Affect of enzyme concentration to the rate of reaction Aim: With the experiment of protein solution‚ in this case egg white added to different pepsin concentrations (0%‚ 0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%) shows‚ as the egg white is a protein and the pepsin works as an enzyme‚ how a higher pepsin concentration and therefore a larger amount of enzymes effect the rate of reaction. Hypothesis: An increased concentration of pepsin speeds up the time the mixture needs to come clear. Introduction:

The data from the experiment demonstrates that the catalase enzyme breaks down the hydrogen peroxide due to its harmful toxicity to the liver. In section A‚ the effect surface area has on the enzyme was tested. The results have proven that as the surface area increases‚ the reaction rate of the enzyme also increases. To illustrate‚ when the liver was ground‚ the bubbles from the reaction reached a maximum height of 150mm in five seconds less than the unground liver which merely reached a maximum
