To verify that the unlabelled soft drink is diet soda rather than soda sweetened with fructose, we'll do a test of the presence of sugar in the drink. Normally a diet soda contains aspartame, an artificial sweetener derived from proteins. A reducing sugar test will reveal whether the drink contains sugar or not. Absence of sugar will indicate presence of artificial sweeteners. The Fehling's solution and Tollens' reagent are two chemical solutions that test the presence of sugar in the drink. The Fehling's solution gives off a red precipitate in presence of sugar and Tollens' solution gives off a silver precipitate in presence of sugar.
the first answer as blood needs to be oxygenated to be passes round the body then when its deoxgenated it will return to the heart to be pumped around the body again
Electrons are also important for the bonding of individual atoms together. Without this bonding force between atoms matter would not be able to interact in the many reactions and forms we see every day. This interaction between the outer electron layers of an atom is call atomic bonding.
Answer:
A Scanning Electron microscope
Explanation:
A scanning electron micriscope beams focused rays of electrons at the outer surface of the cell get a very highly maginified and detailed image of the surface structures. Some disadvantages include that the cell must be dead in order to be examined this way, and this type of microscope is very expensive compared to a light microscope.
