“Test-Tube Burgers” One summer when taking a trip to a friends country house for a weekend I took on the challenge of being a vegetarian. My friend‚ an only child‚ had been raised a vegetarian by parents who were also vegetarians; never once in his life had he eaten meat. Although the family was tolerant of whatever I did‚ I decided this was an opportunity to try it for myself and see what it would be. At the end of the few days I found it quite easy‚ although in reality I did not consume nearly

Recently a scientist by the name of Mark Post helped create a “test tube” beef burger. The burger was grown in a solution of nutrients and cost about 330‚000 dollars to make. The burger was created by taking muscle cells from a cow and growing them into tissue. The meat had to be dyed to make it look like real beef. The meat contains no fat and is disease free. The meat was made in the Netherlands at Maastricht University. It was served to two volunteers and was flavored with egg powder and bread

2.MATERIALS and METHODS 2.1. Nature of Reactants 2.1.1 We placed 3mL of 3 M HCl into each of 3 seperate test tubes. Next we added mossy zinc to the first test tubes‚ Sn granules to the second and Cu filings to the third and compared the rates of evolution of hydrogen gas in each test tube. 2.1.2. We mixed 3mL of 0.02 M KMnO4 and 2mL of 3 M H2SO4 in a test tube and stirred using a glass rod. Next‚ we divided the solution into two. We added 2mL of 0.03 M Na2C2O4 solution to the first half and

Aptitude tests Psychological tests to measure specific abilities‚ such as mechanical or clerical skills. Sometimes these tests must be specially designed for a particular job‚ but there are also tests available that measure general clerical and mechanical aptitudes. An example of Aptitude test is the Minnesota Clerical Test; it is a 15-minutes individual or group test in two parts: number comparison (matching 200 pairs of numbers) and name comparison. Applicants are instructed to works as fast as

Discovering the Mystery of Eleven Test Tubes Karen Radakovich Ph.D. Mohammad Farhad Brittany Cina CH 223‚ Spring 08 Abstract: Eleven mystery test tubes labeled from K-1 to K-11 contained: 6M H2SO4‚ 6M NH3‚ 6M HCl‚ 6M NaOH‚ 1M NaCl‚ 1M Fe(NO3)3‚ 1M NiSO4‚ 1M AgNO3‚ 1M KSCN‚ 1M Ba(NO3)2‚ 1M Cu(NO3)2 respectively. The contents of the test tubes were determined by chemical experiments. Solution K-1 contained NiSO4 because when solution K-9‚ ammonia which was identified by its pungent odor

10 Test Tube Mystery Introduction: The students were handed 10 test tubes with no identification. The students were supposed to design a method in determining what chemical was in each test tube. The list of chemicals is CuSO4‚ NH4Cl‚ NaOH‚ AgNO3‚ KI‚ H2SO4‚ NaBr‚ CaCl2‚ HCl‚ and Pb(NO3)2. The students are expected to determine the chemicals using physical properties‚ litmus paper‚ solubility‚ and the process of elimination. Physical properties‚ such as the color‚ can be determined by sight. Litmus

Research project #2 Test Tube Meat Scientists have recently traveled to the Netherlands to check out different laboratories researching test tube meat. This is a recent study and may seem far-fetched but we could be eating this meat in the next couple of years. With a new study like this there will be many controversial Pros and Cons. The two articles I researched online were; Burgers From A Lab: The World Of In Vitro Meat and the other is from Beefmagazine.com: Test Tube Meat. Both of the
