Introduction: This report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through

Question: Suppose a meteor impact blows some extremophile bacteria from the Earth into the depths of a gas giant planet called planet X ‚ where they evolve into an intelligent species which practises physics. Do you think their physical theories would be similar to ours‚ and if so in what ways would they be likely to be similar? Your answer will necessarily involve some speculation‚ but make sure it involves some careful argument as well. Theoretical physics is one of many braches of physics that

Vision and the Cutaneous System. With this‚ he provided nine different categories of fingerprints‚ which we now know as arches‚ tented arches‚ loops‚ whorls‚ and twin loops. Like the previous researchers‚ he did not focus on using fingerprints for identification. In the late 1800’s‚ Sir William Herschel‚ the chief magistrate of the Hooghly district in Jungipoor‚ India‚ began imprinting fingerprints onto business contracts he made with the natives‚ since the natives were illiterate. Due to this new system

Experiment 2 – Identification of Inorganic Solids Jesse Galina CHM 101 Lab Monday October 1‚ 2012 Unknown Solid – 2 Identifying my cation was rather easy because of the color of the powder when it was first given to me. It was pinkish/slight red when solid and when it was grounded up even further. This observation ruled out every cation except for some hydrated Co (II) salts. After being dissolved in water‚ the solution turned pink which agrees with the statement that the cation was Co

the Unknown Bacteria: Bacillus cereus Brittany Moy Coastline Community College Abstract Bacillus cereus is a Gram-positive‚ facultative aerobic‚ spore-forming‚ rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can

following agar mediums: Blood Agar (pg 168)‚ EMB Agar (pg 170)‚ Mannitol Salt Agar (MSA)(pg 172) )‚ MacConkey Agar (pg 174)‚ and PEA Agar (pg 176) to answer the following: 1. What does the blood agar select for? Blood agar allows distinction among bacteria based on their ability to lyse red blood cells (hemolytic activity). 2. What color is the blood agar? Blood red color. 3. What are the 3 types of blood agar results and how can you recognize them? Beta hemolysis‚ which is the complete

In the unknown identification labs‚ we have identified our unknown as Pseudomonas aeruginosa. Pseudomonas aeruginosa is Gram negative and rod shaped that we found to be motile in the lab. Our strain of P. aeruginosa formed colonies that were round in shape and had scalloped margins on nutrient agar. On our agar slant‚ the P. aeruginosa colonies had a filiform appearance on the edges. I think we correctly identified our unknown as P. aeruginosa because we performed several different tests‚ eleven
