Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential

powder was removed. A pipette was used to add 1 mL of buffer solution to the bottle ATP and the dropper was placed back onto the bottle. The bottle was rolled between the palms of a pair of hands to until the powder was dissolved. The powdered firefly lantern was poured into two Petri dishes in each of the four stations. One was used for the control and the other dish was used for the experiment. To each of the Petri dishes 1 mL of buffer solution was added. At station 1 the control two drops

Boys’ Code of Conduct In the article “How Boys Become Men”‚ written by John Katz‚ he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel‚ The Other Wes Moore‚ both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys‚ as the book‚ The Other Wes Moore

Titration Lab Introduction The purpose of this lab is reach and be able to calculate the equivalence point when we use titration to neutralize a base with acid. The process of the lab was determining the volume of a solution needed to react with a given mass or volume of a sample is called titration. The equivalence point is when the same number of moles of acid and moles of base has been added. Phenolphthalein is used as an indicator because it will have a color change when the equivalence point

Genetically Modified Organisms INTRODUCTION: The purpose of this lab was to identify if non-labeled food products are actually genetically modified foods. Before we could begin testing this theory we first had to gain an understanding about genetically modified organisms in general. This was rather easy because if you have been to any grocery store lately you have without a doubt seen products with labels saying "GMO-free" or even "contains only non-GMO ingredients." GMO actually stands for
