BIOLOGY DIVERSITY: EXAM 1 STUDY GUIDE SCIENCE…Organized body of knowledge of the natural world…Systematic process of acquiring, organizing, & communicating this knowledge Four Rules of Science 1.) Based on best available evidence 2.) Objective: Unbiased allows for trustworthy interpretations 3.) VERIFIABLE , TESTABLE , REPEATABLE 4.) Acquired using scientific method Science is selfcorrecting as work is done it solidifies the results, or demonstrates bad science or bias. Define the following Inductive Reasoning Theory Heritable Deductive Reasoning Law Alleles Homeostasis Speciation Hermaphrodite Biology Reproduction Fact Genes What is a living thing? Differentiate Autotrophs, Heterotrophs, & Mixotrophs Scientific Method 1 OBSERVATION Objective; “Data”; Limited to the senses, but improved with the use measurement devices 2.) QUESTION Based on the collected data 3.) HYPOTHESIS Tentative explanation; not a random guess; not vague; testable 4.) EXPERIMENT Manipulation of a variable or factor; cause and effect, repeat and replicate Observation/Data Question Hypothesis Tested by Experiments STOP Run ACCEPT Another HYPOTHESIS Results support Interpret by comparing Experiment To Hypothesis Redesign Hypothesis/ Experiment Results show no support STOP REJECT HYPOTHESIS Run Another Experiment Redesign Hypothesis/ Experiment Who is Charles Darwin? What were his ideas? Who is Alfred Russel Wallace? FOUR POSTULATES POSTULATE #1 Individuals within a species are variable Disadvantageous: reduced survival = reduced reproduction Advantageous: increased survival = increased reproduction POSTULATE #2 Some of an individual’s variations are passed on to their offspring POSTULATE #3 In every generation more offspring produced than actually survive BREED Bori Natali Only enough food for 5 offspring Only 5 survive and have chance to reproduce POSTULATE #4 Those offspring that survive and reproduce may have inherited variations that give them an advantage relative to other organisms lacking that variation Survivors have a better chance to live long enough to reproduce CONDITIONS FOR EVOLUTION BY NATURAL SELECTION 1.) Variation must exist for a given trait Visible (Size, shape, color) Not Obvious (Behavior/Psychology) 2.) Variation results in differential survival and reproduction 3.) Variation must be heritable MECHANISMS OF EVOLUTION 1.) Natural Selection 2.) Mutation 3.) Gene Flow 4.) NonRandom Mating 5.) Genetic Drift Random Mating Founder Effect Bottleneck Effect Define Species. Differentiate between Sexual Dimorphism and CrypticSpecies. ♀ = Egg Sperm = ♂ ZYGOTE PREZYGOTIC ISOLATION 1.) Mechanical Isolation Body Mismatch “Lock and Key” Mismatch 2.) Geographical Isolation 3.) Ecological Isolation 4.) Behavioral Isolation 5.) Temporal Isolation 6.) Prevention of Gamete Fusion POSTZYGOTIC ISOLATION 1.) Hybrid Invariability 2.)Hybrid Infertility
