Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine

A&P – P 1 OF 2 This course is a study of “Human Anatomy and Physiology.” Humans can be classified as: - Animals (we are multicellular‚ motile organisms that lack cell walls) - Vertebrates (we have backbones) - Mammals (we have hair‚ mammary glands‚ 3 bones in each ear) - Primates (we have opposable thumbs‚ 2 clavicles‚ forward facing eyes) - Hominids (we are bipedal and have a large brain size to body size ratio). Anatomy is the study of animal structure. The word comes

Section 1 : Identifying the Genetic Material Griffith’s Experiments In 1928‚ Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against pneumonia. A vaccine is a substance that is prepared from killed or weakened disease-causing agents‚ including certain bacteria. The vaccine is introduced into the body to protect the body against future infections by the disease-causing agent. Griffith discovered that harmless bacteria could turn virulent when mixed with bacteria that cause
