Biology Final Review Chapter 1 Biology unifies much of natural science * Living systems: most complex chemical systems on Earth * Constrained by properties of chemistry and physics * Science is becoming more interdisciplinary (combining multiple fields) 7 characteristics of all living organisms 1. Composed of cells 2. Complex and ordered 3. Respond to their environment 4. Can grow‚ develop‚ and reproduce 5. Obtain and use energy 6. Maintain internal balance

Aim To investigate in the amount of antioxidants present in the two given tea samples for four consecutive brews each. Introduction Hypothesis: The amount of antioxidants would decrease as the number of brews increases. Biological principal: An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons. Oxidation reactions can produce free radicals. These radicals can start chain reactions. When the chain reaction occurs

Suzanne Roles Suzanne Roles studied painting and printmaking at Camberwell School of Art from 1979 to 1983.Her still lives are based upon photographs taken with macro lenses and also use natural light to create dramatic shadows‚ therefore exploring the main interests of space‚ colour and texture. She is influenced by 16th/ 17th century Spanish still life artists. “My still lives are based upon aerial photographs taken using natural light to create dramatic shadows‚” she says‚ "therefore exploring

Aim: 1) To determine the effects of different salt concentration on the percentage of weight change in potato cubes 2) To determine the isotonic solution concentration for the potato Hypothesis: 1) If the concentration of the salt solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through

BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis

Carl Kogstrom Neuberg IB MYP Biology 9 May 2014 Effects of Genetically Modified Food Genetically modified food contributes a major portion to the world’s food supply. Genetically modified food (GMF) is food that is produced from plants or animals that have had artificial changes to their genetic material. GMFs have been tested and experimented on since 1992 and sold commercially since 1994. The DNA of crops has been altered to make them grow faster as well as resist many different pesticides. This
