Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals‚ Figure 1. This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed at frequencies > 1500 cm-1. These infrared frequencies were shown in Table 2. An infrared spectrum of an authentic aspirin was used to distinguish how authentic the infrared spectrum from the synthesis was shown in Figure 2 In this lab‚ aspirin was synthesized

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine

Java CIS 109 Assignment 1 A. Programming theory 1. Basic Ideas 1(a) Delimiters are used as comments. The Phrase is put in there to be shown to the user whilst programming‚ but is not shown when the program is to run. Those delimeters indicate comments‚ the compiler ignores what is inside. 1(b) “import java.io*;” means that the complier will check what libraries are necessary to compile the program‚ and it will simply import them. In this case‚ the program would not be able to run without
