Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

Abstract—We focused on Buck/Boost Rectification by Single Phase Matrix Converter with fewer numbers of switches. The conventional matrix converter consists of 4 bidirectional switches‚ i.e. 8 set of IGBT/MOSFET with anti parallel diodes. In this proposed matrix converter‚ only six switches are used. The switch commutation arrangements are also carried out in this work. The gate pulses to the switches are provided by the PWM techniques. Step up or step down DC outputs can be obtained by using suitable

WATER QUALITY 1 Water Quality and Contamination SCI207: Dependence of Man on the Environment Water Quality and Contamination Abstract In this experiment water quality and contamination of groundwater were investigated. First‚ I will observe the effects that many pollutants have on groundwater. I predict that in this experiment the oil and vinegar will create the largest quality of contamination to the water‚ while the laundry detergent will just create a bad smell to it. Considering

Lab Report Microscopic Study: Investigating Osmosis in Red Blood Cells Lab Report Investigating Osmosis in Red Blood Cells Introduction: The flow of water across a permeable membrane is called osmosis‚ and during this process‚ water moves down its concentration gradient. A solution surrounding a cell is hypertonic if it contains more solute particles than the inside of the cell‚ and the water will move out of the cell into the surrounding hypertonic solution by osmosis. If the solution

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation

For this lab‚ the expected outcomes are that when the heart rate and blood pressure are measured‚ both will increase when the heart has to pump against gravity‚ after exercise the heart rate will increase then return to normal‚ and as the subject inhales‚ it will be lower than when they exhale. Methods For this lab report‚ the laboratory manual (2009) was used for all labs. While completing lab five‚ electrodes were hooked up to the subject. After calibration for this lab‚
