August 29, 2011 AP Biology/Anatomy Physiology Class Notes Ms. Ziebart 1st Period ----------------------------------------------------------------------------------Class Starts Test moved to Friday (Test mentions)It covers chapters 1-3 Graphing is very important in AP Biology Progress Report shipping out before test. -------------------------------------------------------------------------------Negative Feedback and ATP ATPATP is created from Glucose.Cellular Respiration - involves creation of ATPATP - is the energy resource for cells As in the case of Negative Feedback, with similar topics you need to know it and know examples you can't just understand it. You have to be able to show you understand it. Negative Feedback InsulinGlucagon Diabetic = too much sugarinsulin decreases sugarinsulin opens cellsglucagon takes glycagon from storage Negative Feedback "response is a reduction" Positive + Negative Feedback <---Know for test) This topic will !!!!also be on future tests. -------------------------------------------------------------------------------Scientific Inquiry 2 types of inquiryDiscovery and Hypothesis Watson and Crick - cracked the overall mystery of DNA and the double helix. They used discovery method. Hypothesis based inquiry requires it to be testable or falsifiable.Experiment DesignControlled experiment you need:ControlDependent Variable-------------------------------------------------------------------------------Discussion about Essays and Experiment Design. The Essays written on the AP test force you to design an experiment.They to look to see if you can take an idea all the way to application. Designing an experiment is a possible essay topic for the !!!!Test on Friday and/or future tests. -------------------------------------------------------------------------------Natural SelectionNatural Selection deals with characteristics shared among a population. The theory of evolution does not regard individual adaptations. Chemistry RecapMatter is made up of elements An element is a substance that cannot be broken down to other substances by chemical reactions. About 25 of the 92 elements are essential to life. Carbon, Hydrogen, Oxygen, and Nitrogen make up 96% of living matter. Most of the remaining 4% consists of calcium, phosphorous, potassium, and sulfur. Trace elements are those required by an organism in minute quantities. Know Periodic Information such as Atomic Number, Atomic Mass. !!!
