Lab Report Background Information: Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong‚ silvery-white‚ light-weight metal (one third lighter than aluminum). In a powder‚ it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk‚ but once ignited‚ it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with

FOOD CHAINS and FOOD WEBS There are two types of feeding relationships: autotrophic and heterotrophic. Autotrophic organisms make their own food by the process of photosynthesis e.g. plants. Heterotrophic organisms cannot make their own food (i.e. cannot carry out photosynthesis)‚ therefore must eat other organisms to get their nutrients e.g. animals. A food chain is the feeding relationship among organisms or the series of living organisms that eat each other. A food chain shows the transfer

Why There Should be a Limit on Food Additives For many centuries people have been adding things to preserve foods. An example of this is using salt to preserve meats or adding herbs to enhance the flavor of any other type of food. In recent years‚ however‚ the amount of additives in food has dramatically increased‚ and some of the items that are being added have been questioned by scientists as well as some consumers. Some additives have been known to cause sickness and contribute to the formation

The price is compatible with the pocket money for most of the kids and the teenagers who frequent the joints and it also is a great buy to makeup for the shortage of time. It is often quicker to eat or prepare than healthy

binds the nucleoside inhibitor site. When it binds this site‚ it stabilizes the inactive T state and blocks the catalytic site which needs to be open for enzyme activity to occur. The glycogen phosphorylase b was purified with hydrophobic column chromatography and the concentration was determined with a Bradford Assay. The kinetics of glycogen phosphorylase b were studied by finding a molar extinction coefficient‚ 0.1617 mM cm-1 A-1‚ for
