Document Summary

Lecture #1: inductive reasoning: form of thinking that uses a set of observations, deductive reasoning: form of thinking that uses a set of principles or laws, cells: basic unit of structure and function. Lowest level of structure capable of performing all activities of life: heritable information: all life is based on heritable information. All life uses the same genetic code: organisms as open systems: organisms exchange energy and materials with their surroundings, structure and function: form fits function . A bird wing"s structure provides clues to it"s function. Substances with polar or ionic bonds that can form hydrogen bonds with water: hydrophobic substances: repel water. Basic= 8-14: buffers: chemical processes of cells that resist changes in ph of a solution, by donating h+ when the solution is depleted of h+ (these are acids). Or donating oh- when the solution when there is an excess of h+. Can also accept h+ to lower the h+ concentration: molarity: molar concentration.
