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

Essay Why Human History Cannot be Understood in a Vacuum When trying to decipher what Clive Ponting meant when he said‚ “Human history cannot be understood in a vacuum‚” I have deemed it is necessary to break the explanation up into three different parts. The first being‚ what does human history look like through a vacuum? What is it comprised of‚ what are its characteristics? The second being if human history is not understood in a vacuum‚ then exactly how is it understood? What does that

tubing and bend the glass tube into a U-shape. The glass tube is then filled with a liquid‚ typically mercury‚ so that all trapped air is removed from the sealed end of the tube. The glass tube is then positioned with the curved region at the bottom. The mercury settles to the bottom After the mercury settles to the bottom of the manometer‚ a vacuum is produced in the sealed tube. The open tube is connected to the system whose pressure is being measured. In the sealed tube‚ there is no gas to exert

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
