Come and go with meLETS TAKE A LOOK INTO BIOLOGYI.What is Biology?A.Biology- the study of life.B.Organism- anything that possesses all the characteristics of life.II.CHARACTERISTICS of LIVING THINGSA.Have an orderly structure (Organization)B.Produce offspring (Reproduction)C.Grow and develop Growth- results in an increase in the amount of living material and formationof new structure2.Development- All the changes that take place during the life of an organismD.Adjust to changes in the environment.1.Environment- An organisms surroundings including air, weather, temperature, and any other organisms in the area.III.RESPONSE to the ENVIRONMENTA.Stimulus- any condition (external or internal) in the environment that requires an organism to react.B.Response- a reaction to stimulus.C.Homeostasis- regulation of an organisms internal environment to maintain conditions suitable for its survival steady state.1.Living things reproduce themselves, grow and develop, respond to external stimuli and maintain homeostasis by using ENERGYD.Energy- the ability to cause change.Organisms get their energy from food.IV.LIVING THINGS ADAPT and EVOLVEA.Adaptation- any structure, behavior or internal process that enables an organism to respond to stimuli and better survive in an environment.1.Inherited from previous generations.2.Individuals with more suitable adaptations are more likely to survive.B.Evolution- the gradual change in a species through adaptations over time.Homework: Define the Following Vocabulary WordsAdaptationBiologyDevelopmentEnergyEnvironmentGrowthHomeostasisOrganismOrganizationReproductionResponseAsexual reproductionSpeciesSexual reproductionStimulus V.A.Species- group of organisms that can interbreed and produce fertile offspring in nature..B.Theory- explanation of a natural phenomenon. Explains natureC.Law- describes nature.SCIENTIFIC METHODDefine the ProblemCollect InformationForm a HypothesisExplanation or tentative answer to a question ExperimentInvestigation that test a hypothesisCollect Data from experimentDraw ConclusionPublish Information*** PAGE 17 METHODSVI.A.Some experiments involve 2 groupsControl Groupa.Control- standard all conditions stay the same (shows what happens if there is not change to the independent Variable).Experimental Groupa.Test Group. One single condition is tested.1.Independent Variable-(manipulated variable) Changed condition.2.Dependent Variable- 2 (responding variable) Changes the result from the independent variable.PAGE 13VII.A.Science was developed because humans have always been curious about the natural world. Leading to the beginning of cause and effect.B.Science is defined as a process that produces a body of knowledge about nature. The application of scientific research to societys needs is called technology.C.The use and application of science is a step by step process called the scientific method.VIII.SCIENCEA.LIMITS TO SCIENCE1.Some things are untestable because of the lack of technology2.Science cannot determine what is socially or morally correct.B.KINDS OF RESEARCH1.Quantitative research- this research is analyzed by comparing numerical data. It may be used to make tables or graphs, which allows for large amounts of information to be easily understandable.2.Qualitative research- expresses quality and observational data, which is written descriptions of what scientists observe.IX.ETHICSA.Ethics- refers to the moral principles and values held by humans.1.Science may not consider all possible ethics. Therefore, society as a whole must take responsibility for the ethical use of scientific discoveries.B.Technology- the application of scientific research to meet societys needs and problems.Homework: Define the Following Vocabulary WordsControlDataExperiment Dependent VariableTheoryIndependent VariableEthicsScientific MethodTechnologyLouis PasteurFranciso RediBiogenesisBioticBiotechnologyAbioticCellTissueOrgansOrgan SystemSpontaneous GenerationDiversitySI- allows for scientist around the world to have a common basis for understanding data METER (m)LENGTHRULERKILOGRAM (Kg)MASSBALANCELITER (l)VOLUMEGRADUATED CYLINDERSECOND (s)TIMESTOP WATCHCELSIUS (c)TEMPERATURETHERMOMETERWilliam Harvey: (1628) showed how blood circulates through the body in blood vessels.Gregor Mendel: father of heredity, worked with pea plantsEdwin Chargaff: (1947) discovered that for every adenine there is a thymine, and for every guanine there is a cytosine-base content of (DNA pairs)Alexander Fleming: (1928) discovery of the first antibiotic; penicillinRobert Hooke: discovered and named the cell while observing corkRachel Carson: warned of the danger of increased pesticides and the damage it was doing to nature; wrote Silent SpringJane Goodall: studied chimpanzees Charles Drew: did research in the collection and storage of blood plasma.Charles Darwin: developed the theory of evolution based on natural selection.James Watson/Francis Crick: (1953) determined the structure of DNA to be a double helix.George Washington Carver: (botanist) developed several industrial uses for the peanut.Carolus Linnaeus: father of classification developed two-word system for naming organisms (binomial nomenclature).Edward Jenner: (1796) developed a vaccine for smallpox.Anton von Leeuwenhoek: 1st microscope.BRANCHES OF BIOLOGYBiology: study of lifeBotany: study of plantsZoology: study of animalsMycology: study of fungiGenetics: study of how characteristics are passed from parent to offspring.Anatomy: study of an organisms structureBacteriology: study of bacteriaEcology: study of the interaction of organisms with their environmentCytology: study of cellsEmbryology: study of early developmental stages of organismsHerpetology: study of reptilesHistology: study of tissuesIchthyology: study of fishMorphology: study of the gross anatomy of organismsOrnithology: study of birdsParasitology: study of parasitesPathology: study of diseasesPhysiology: study of internal function of organismsTaxonomy: classification of living thingsVirology: study of virusesEntomology: study of insectsEugenics: study of heredity in humansLANGUAGE of SCIENCE PREFIXESA or anNot or nonMesoMiddleEndoInside, innerAeroNeeding oxygen or airAntiAgainstAutoSelfBioRelated to lifeChloroGreenCytoCellArthJoint, jointedDiDoubleMonoSingular or oneGeoPertaining to earthEpiAboveExoOuter, externalGastroStomachHemoBloodHeteroDifferentHomoSameMicroSmallMacroLargeMultiConsisting of many cellsPhotoPertaining to lightPreBeforeLipoPertaining to fatPolyManyLANGUAGE of SCIENCES SUFFIXES*** Pasteurs Experiment-cystPouch-dermSkin, layer-saccharideSugar-itisInflammation-logyStudy of-meterMeasurement-osisCondition-phaseStage-podFoot-stasisStationary condition-lysisTo break-synthesesTo build or make-phageEaterRedi and PasteurPage 380-381(Abiogenesis) Spontaneous Generation- the idea that nonliving material can produce life.Biogenesis- the idea that living organisms come from other living organismsPASTEURS GOOSE NECK OR S SHAPED FLASKWRITE EACH STATEMENT AND COMPLETE THE BLANK1.
