Abstract: The focus of this experiment was to identify unknown bacteria provided. The identification of unknown bacteria is beneficial in many aspects of the research of microorganisms and also aids physicians to treat patients correctly. Various tests were performed to provide the fermentation abilities‚ presence of particular enzymes‚ and biochemical reactions. Qualitative observations were made on the tests in identification process. The data from experimentation provided sufficient results

AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized

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

Write a simple equation to show how ATP is synthesised from ADP: ADP + Pi ATP Give two ways in which the properties of ATP make it a suitable source of energy in biological processes: 1. Energy released in small/suitable amounts 2. Soluble 3. Involves a single/simple reaction Humans synthesise more than their body mass of ATP each day.

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

Population Ecology Ingrid Rhody BIO/101 March 7‚ 213 Kirsten Hagen MS Population Ecology Population ecology is the affect of a populations density and extension. When a group of single species occupy the same general area it is known as a population. This group of species will rely on resources and the same environmental atmosphere. The number of species within a group that occupy the same area or habitat is known as population density. Some ecologists use different types of techniques
