Unformatted text preview: Evolution of adaptations in the population Differences in reproductive success Over production and competition Heredit ar y var iations Population of organisms Population of organisms Chapter 1- Exploring Life • Biological H ierarchy- from the smallest building blocks to the whole picture. o Molecules-> Organelles-> Cells-> Tissues-> Organs/Organ Systems- > Organisms-> Populations-> Communities-> Ecosystems-> The Biosphere • Emergent Properties- due to the arrangement and interactions of parts as complexity increases. o Thoughts and memories are emergent properties of nerve cell networks. • Reductionism- reducing complex systems to simple components that are more manageable to study. o Understanding the nucleotide in order to understand the phenotypic characteristic of a person. • Negative Feedback- the product of a reaction slows that process down. • Positive Feedback- the product of a reaction helps to speed up the process. • Taxonomic System- The order in which all living species on the planet are placed. Based on Latin words and roots. o Domain o Kingdom o Phylum o Class o Order o Family o Genus o Species D amn! K ing P hillip C ame O ver F rom G ermany S aturday! • Domains of Life- the highest order of the taxonomic system. Composed of certain Kingdom. o Three Domains: Archaea • Archaea Bacteria • Bacteria Eukarya • Protista • Animalia • Plantae • Fungi Dar win’s Observations- Natural Selection o Fig. 1.20 • Discovery Science- descriptive science. Describes natural structures and processes as accurately as possible through careful observation and analysis of data. o Data- recorded observations o I nductive reasoning- deriving generalizations based on a large number of specific observations. o Scientific method- order in which to test a question. Observation Hypothesis Prediction Testing Conclusion OH ! P lease T hink C ritically! o Hypothesis- tentative answer to a well-framed question. o Theory- more broad than hypothesis. General enough to spin off of many hypotheses. Supported by a much more massive body of evidence, compared to a hypothesis. Chapter 2- The Chemical Context of Life • Element- a substance that cannot be broken down to other substances by chemical reactions. • Compound- a substance consisting of two or more different elements combined in a fixed ratio. • Atom- the smallest unit if matter that still retains the properties of an element. o Subatomic particles- Neutron- no charge Electron- negative charge Proton- positive charge • Protons and Neutrons are located in the atomic nucleus, while electrons around located in the region around the nucleus. • Atomic number- denotes the number of protons (thus electrons, since they are equal) in the atom. It is written as a subscript to the left of the symbol for the element....
