Some dreams are so realistic and well organized that we feel as though they must be real-- that we simply cannot be dreaming this time. Dreaming has always been the...
Abstract Experiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96, and the pKa's found experimentally were 2.0, 4.0, and 9.85. The accepted pKa values were found to be 2.10, 4.07, and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to...
Apes have 13 species of large, highly intelligent primates, including Chimpanzees, Gorillas, , and Orangutans. Apes are sometimes confused with Monkeys, but unlike their smaller primate counterparts, apes do not have tails and their arms are usually longer than their legs. Apes live in tropical woodlands and forests of Africa and Asia. Despite sha...
Earth Layers: The Crust and Upper mantel The theroery of Plate Tectonics The theory of plate tectonics states that the earth's upper mantle and crust, have been broken into huge slab pieces, which are also called plates. Divergent Boundries Divergent boundaries are mostly found on the seafloor, and is when there are two tectonic plates that are...
