Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Hitler was responsible for the outbreak of World War 2(1939) to a significant extent. The many things that he did like going against the Treaty of Versailles which included the rearmament of Germany‚ his Lebensraum policy where he wanted to take over neighboring lands and gain more territory for Germany and his disrespect to the treaties he made. While Hitler was a great cause for World War 2‚ he was not the sole reason. The Great Depression‚ the weak leaders of the League of Nations and their

considering that the photoreduction period took a couple extra days due to lack of sunlight‚ loss of product can be attributed to this since we only could get 2.11g/3.0g of benzpinacol from the start of the lab. And since benzpinacol was the limiting reagent‚ before starting part 2 of the lab this already set us up for some loss in % yield. Also when we transferred our product from the filtration funnel to the watch glass there was product loss because many of the crystals were stuck in the flask

Lab Report #1: Observing Bacteria Microbiology Abstract: This lab exercise familiarized the student with the use of a microscope by observing and identifying various different slides under the microscope. The student practiced observing the given slides under the 10x‚ 40x‚ and 100x (oil immersion) objective lenses‚ which allowed for the identification of the different organism’s shapes and sizes. Purpose: The aim of this exercise is to equip the student with the knowledge

Assuming that states are rational actors‚ explain the outbreak of war? Part 1 Assuming that states are rational actors‚ why do states fight over valued possessions rather than negotiating peaceful terms‚ which would avoid the costs of war? For the most part‚ it is widely agreed that one of the most fundamental causes of war is having anarchy in the international system. The lack of a united international government system can be very problematic because each state believes itself to

In this lab‚ we tested the effect of flame on different chemical solutions. In order to do this‚ we used a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition

occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method used to perform this lab will be to combine a metal with a solution to produce a chemical reaction causing one element to replace another element and isolating the product from the liquid to determine its mass. Background: A chemical equation shows all substances that are

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

Glowing Bacteria Lab Introduction- 1. Transformation involves the transfer of genetic information into a cell by directly taking up foreign DNA from its surroundings. This DNA is then incorporated into the host cell’s own DNA. This transformation usually occurs within plasmids‚ small circular DNA molecules separate from its chromosome. After the recipient cell is infected with the DNA‚ the cell will move on with replication‚ producing offspring with traits encoded by the plasmid. These plasmids

Jennifer Anatomy and Physiology Enzyme Lab Report Introduction The chemical reaction that is being studied is the hydrolysis of starch. The enzyme that is being studied is amylase. This experiment is looking at the effect of temperature on the rate of the enzymatic hydrolysis of starch. My hypothesis is that the higher the temperature the faster the hydrolysis of the starch would occur. The rationale behind this is that heat
