Abstract This experiment made use of the Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis technique to plot a curve displaying the electrophoretic mobilities of 7 proteins against the known molecular weights. Another sample was also run in the SDS-PAGE but with an unknown protein sample. Two proteins were found in the sample and their electrophoretic mobilities …

The agar changed from red to purple, and a noticeable border was present rounding the colonies that exhibited growth on the dish. The ASH agar did not yield a color change. The Imitation agar exhibited a change with S. erasures and the mixed culture, but no change with E. Coli (Table 2). Table 2. Indication …

Energy (TAP), initially in the form of glucose (macroeconomics) is later formed by condensation reaction into starch (polysaccharide). These alpha-glucose units are attached together by glycoside bonds. Starch is formed after the Calvin Cycle in the Storms. Carbon dioxide is present in the air and the water is gained from precipitation or morning dew. The …

The endocrine system works with the nervous system to regulate and coordinate body functions. While the nervous system works quickly and sends messages directly to specific body parts, the endocrine system takes a longer time to produce a longer- lasting effect. The system operates by releasing chemical messengers called hormones into the bloodstream, which travel …

Specific heat is defined as the amount of energy necessary to produce a temperature change of 1 co per gram of substance. The specific heats of different substances vary, and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimeter. In this lab activity, calorimeter will be …

Also the total amount of energy in a closed system never changes. Along with my wonderful partner Kelvin e thought that energy in a closed system will remain constant throughout unless there is an outside energy such as “work” or friction. We also discussed the differences and similarities between closed and open systems. We wanted …
