Microbiology Lab ReportPractica #1BTC307LAmber AmelingmeierThursday‚ September 18‚ 2008OBJECTIVESIn this lab experiment two different types of bacteria‚ Escherichia coli and Staphylococcus aureus‚ were grown singly and mixed on four different types of agar in order to observe the varying morphologies within the colonies. Resulting data was analyzed to provide understanding of the use of differing culture media and conditions for bacterial growth. RESULTSFour different agar types were used in this

PRINCIPLE OF GENERATION‚ TRANSMISSION AND DISTRIBUTION OF HIGH AC VOLTAGES INTRODUCTION The potential benefits of electrical energy supplied to a number of consumers from a common generating system were recognized shortly after the development of the ‘dynamo’‚ commonly known as the generator. The first public power station was put into service in 1882 in London (Holborn). Soon a number of other public supplies for electricity followed in other developed countries. The early systems

Tradition is the transmission of customs or beliefs from generation to generation‚ or the fact of being passed on in this way. Many people value and like their traditions but for many others they feel (locked in a prison) by certain parts of their tradition. The traditions we receive have been handed down to us through many generations which have been influenced by our parents and their background history. This helps to control our identity and through their teaching‚ it gives us a sense of belonging

has 51% light transmission at pH 2. At pH 9 the Trypsin has 39% light transmission. Between pH 2 and pH 9 the percentage of light transmission decreases at a steady rate‚ until it reaches pH 8 where there is a steep increase from 30% to 39% as the enzyme has reached its optimum pH at 8. During the experiment in the boiling tube this pH had the deepest red colour as the most protein gelatine was broken up. This meant that in the colorimeter when testing to see what the light transmission‚ this pH let

Organ Harvesting Research Paper We have all heard about the stories and have seen the movies in which the protagonist wakes up in a tub covered in tons of ice and stitches in his side only to realize that he was a victim of organ theft. There have been many movies surrounding this horrid topic‚ and many people believe this concept is fictitious; however these movies have partial truth to them. There are many cases across the globe in which people have been given faulty organs‚ and cases in which
