a set up that includes a Hirsch funnel‚ and then rinsed with 9.8 mL of hot water and 5.0 m of ice-cold 95% ethanol. Once rinsed‚ the solids were then recrystallized with a 1:3 ratio of ethanol:acetone; which include 10 mL of ethanol and 20 mL of acetone‚ giving us a total volume of 30.0 mL. Once the 1:3 ratio of ethanol:acetone was added‚ the crude produce is then dissolved by heating the solution on hotplate with the heat knob on about 3-4‚ so as to not overheat the product. Once fully dissolved

MICROBIOLOGY SECTION The microbiology section aims at studying yu ailments and diseases from the isolation of suspected causative organisms. The processes involved in the isolation of these organisms include; culturing‚ staining‚ microscopy and sensitivity tests. Samples collected for examination include; stool‚ blood‚ sputum‚ urine‚ vaginal swab‚ wound swab and wound biopsy. Bacterial Culturing and sensitivity Cultures are carried out to isolate suspected organisms from a sample. There are different

Health and Safe Legislation and Regulation You are required to research two different engineering environments that you have come knowledge of. It may be best if one is an electrical environment and one a mechanical environment. For each of these environments: • Identify a minimum of four different sets of regulations that would be relevant • Describe a minimum of three key features of each of the sets of regulations you have chosen.

We recorded our findings on the table labeled table 1. Table 1 shows the transmittance at each wavelength on a table from 400 to 720. The information on Figure 1 came from the leaf extract on the paper chromatography that we used; with the help of acetone we saw the spectrum and the differences of the different pigments. Percentage transmittance in Table 1 show that the lower the number‚ the more dense that solution is at that specific wavelength. As the numbers get higher‚ the less dense it is and
