My partner and I were given unknown number 3 in the laboratory. After performing various tests over the course of a few weeks on our unknown‚ we came to the conclusion that our unknown organism is Klebsiella pneumoniae (K. pneumoniae). K. pneumoniae is a gram negative bacillus shaped microorganism. We observed that K. pneumoniae is a nonmotile organism. We performed multiple tests on our unknown culture‚ therefore we are very confident that it is correctly identified. We identified that K. pneumoniae

During the lab experiment six different test were conducted. Each test consists of chemicals to be tested using 3 to 10 drops of the additive in order to observe a change. With any experiment you compose a hypothesis; where you make an educated guess. The hypothesis will primarily be‚ which base chemical will produce the greatest change based on the additive. Experiment 6.1 (Starch) when adding the three drops of Iodine to each tube observe the color change. When performing this test the chemical

Background In the Flame test lab we took a simple wire‚ looped it‚ and rinsed it in HCL (Hydrochloric Acid ). Then we dipped the wire in the different samples provided. The samples provided were Sodium‚Potassium‚Calcium‚ Barium‚ Strontium‚ Lithium ‚ and Copper II. Finally we put the wire loop into the flame of the bunsen burner. The flame erupted into many different colors for each specific sample. We then used the colors we recorded to find the two unknown samples given to us. But the question

Nature vs. Nurture 1 Gender bias in society a Result of Nurture not nature Nature vs. Nurture 2 Over the course of history there had been a lot of frequently asked and intriguing questions directed towards the mental development of humans. Arguable one of the most interesting of them all is the following: when and how do children acquire a gender identity. As a result of hours of thorough research involving modern media sources involving: T.V. shows‚ advertisements‚ music

What to do When You Screw Up (This essay was originally published in the electronic Newsletter for the Honors Program for the College of Letters and Science at UC Santa Barbara in Winter 2009.) Many people mistake me for a successful person‚ so I try to keep a record of all my failures‚ and for reasons that will become clear later in this essay. True failure and rejection didn’t begin for me until late adolescence: when I applied for college‚ I got just one rejection letter‚ but it felt like

Biology 100 Lab Laboratory Report Title: Identifying the four major classes of macromolecules through various tests. Group Members: Antonia Johnson‚ Payton Ewing‚ Lenneisha Hepburn‚ Kendisha Hanna‚ Introduction: Macromolecules also known as biological molecules are monomers which are the simple units of polymers. All macromolecules contain carbon and hydrogen which are found in organic compounds. In this Experiment we will test for the presence of protein‚ starch‚ lipids‚ and sugars by analyzing

FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests and

During the laboratory a Tinius Olsen Tension Test equipment was used‚ and the test samples were from low and high carbon steel and timber with grains parallel and perpendicular to the load. Test equipment and materials The test equipment used during the laboratory is one of the Benchtop Materials Testing Machines made by Tinius Olsen. This machine can test different types of

Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature‚ some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However‚ the excited configuration is unstable‚ and the electrons must return back to their positions in the lower energy level. As they return‚ the energy that was previously absorbed is now emitted
