BIO 181 Final: Biology Spring 2012 Final Review.docx
Document Summary
All information is separated into which test it was on. At the end of each section there are 5 questions with answers. Characteristics of life: hierarchy of organization, cells-basic unit of structure and function, reproduction-life is continued through heritable info(dna, energy-metabolism. Interact with environment-homeostasis, respond to stimuli: growth and development-irreversible, adaption and evolution-core theme of biology, movement-basic property of cells, water-all living things require water. Controlled experiment: controlled variable: influence dependent variable. Independent variable: manipulated, control over: dependent variable: passively observed, measured. Darwin"s theory: variation, competition, survival of the fittess. Species concepts: phylogenetic-based on characteristics (dna, biological-most often used! Potential to interbreed with one another to produce viable fertile offspring- cannot interbreed with other species: evolutionary-derived from a single lineage distinct from others and has its own evolutionary tendencies and historical fate, ecological-each species occupies a nice. Reproductive isolating mechanisms: prezygotic: temporal, behavioral, mechanical, gametic, habitat, posyzygotic: zygotic mortality, hybrid sterility, hybrid breakdown.
