Description
GENERAL BIOLOGY IREVIEW QUESTIONSChapter 1 Exploring Life1Diagram the hierarchy of structural levels in biological organization from the simplest to the most complex levelATOMSMOLECULESORGANELLESCELLSTISSUESORGANSORGAN SYSTEMORGANISMPOPULATIONCOMMUNITYECOSYSTEMBIOSPHERE2What are the two major dynamic processes of any ecosystemCYCLING OF NUTRIENTSONE WAY FLOW OF ENERGY FROM SUNLIGHT TO CONSUMERS3Distinguish between prokaryotic and eukaryotic cellsPROKARYOTIC CELLS LACK MEMBRANE ENCLOSED NUCLEUSORGANELLESEX BACTERIAARCHAEAEUKARYOTIC CELLS HAVE MEMBRANE ENCLOSED NUCLEUS AND ORGANELLES EXPROTISTSPLANTSFUNGIANIMALS4Distinguish between positive and negative feedbackNEGATIVE FEEDBACKACCUMULATION OF AND END PRODUCT OF A PROCESS SLOWS DOWN THAT PROCESSPOSITIVE FEEDBACKEND PRODUCT SPEED UP ITS OWN PRODUCTION5What is homeostasisHOMEOSTASIS IS A STEADYSTATE PHYSIOLOGICAL STATE OF THE BODY6What are the three domains of life BACTERIA ARCHAEA EUKARYA7List and distinguish among the three kingdoms of multicellular eukaryotic lifePLANTAEMOST PLANTS PRODUCE THEIR OWN SUGARS AND FOOD BY PHOTOSYNTHESISFUNGIMOST FUNGI ARE DECOMPOSERS THAT ABSORB NUTRIENTS BY BREAKING DOWN DEAD ORGANISMS AND ORGANIC WASTESANIMALIAANIMALS OBTAIN FOOD BY INGESTING OTHER ORGANISMS8Distinguish between discovery science and hypothesisbased scienceDISCOVERY SCIENCE IS DESCRIPTIVE DESCRIBES NATURAL STRUCTURESPROCESSES AS ACCURATELY AS POSSIBLE THROUGH CAREFUL OBSERVATIONANALYSIS OF DATAHYPOTHESIS BASED SCIENCEPREDICTIONS THAT CAN BE TESTED BY MAKING ADDITIONAL OBSERVATIONS OR PERFORMING EXPERIMENTS9Distinguish between quantitative and qualitative dataQUANTITATIVE DATA IS GENERALLY RECORDED AS MEASUREMENTSQUALITATIVE DATA IS NORMALLY IN THE FORM OF RECORDED DESCRIPTION10Describe what is meant by a controlled experimentA CONTROLLED EXPERIMENT IS ONE THAT IS DESIGNED TO COMPARE AN EXPERIMENTAL GROUP WITH A CONTROL GROUPIDEALLY THE EXPERIMENTAL GROUP AND THE CONTROL GROUP DIFFER ONLY IN THE ONE FACTOR THAT THE EXPERIMENT IS DESIGNED TO TESTChapter 2 The Chemical Context of Life11Distinguish between an element and a compoundAN ELEMENT IS A SUBSTANCE THAT CANNOT BE BROKEN DOWN INTO OTHER SUBSTANCES BY CHEMICAL REACTIONSTHERE ARE 92 NATURALLY OCCURING ELEMENTS AND ABOUT 25 OF THESE ARE ESSENTIAL FOR LIFEA COMPOUND IS A SUBSTANCE THAT CONSISTS OF TWO OR MORE ELEMENTS IN A FIXED RATIONEX TABLE SALTNACL SODIUM CHLORIDE SODIUM IS A METAL AND CHLORINE IS A GAS BUT THEY CAN COMBINE TO FORM TABLE SALT112Distinguish between each of the following pairs of termsneutron and protonoA NEUTRON IS ELECTRICALLY NEUTRALoA PROTON IS POSITIVELY CHARGEDatomic number and mass numberoTHE ATOMIC NUMBER OF AN ELEMENT IS THE NUMBER OF PROTONS IN THAT ELEMENTS NUCLEUSoTHE ATOMIC MASS OF AN ELEMENT IS THE SUM OF BOTH THE PROTONS AND NEUTRONS IN THAT ELEMENTS NUCLEUS13Explain how the atomic number and mass number of an atom can be used to determine the number of neutronsTHE NUMBER OF NEUTRONS OF AN ELEMENT CAN BE DETERMINED BY SUBTRACTING THE ATOMIC NUMBER FROM THE ATOMIC MASS OF THE ELEMENT14Explain how two isotopes of an element are similarExplain how they are differentTWO ISOTOPES OF AN ELEMENT HAVE THE SAME NUMBER OF PROTONS AND ELECTRONS SAME ELEMENT WITH DIFFERENTOF NEUTRONS BUT DIFFER IN THE NUMBER OF NEUTRONS THAT THEY HAVE15Distinguish among nonpolar covalent polar covalent and ionic bonds NONPOLAR COVALENT BONDSWHEN ELECTRONS IN A COVALENT BOND ARE SHARED EQUALLYEX BOND BETWEEN CARBONHYDROGEN CH4POLAR COVALENT BONDSWHEN TWO ATOMS THAT DIFFER IN ELETRONEGATIVITY BOND AND THEY DONT SHARE THE ELECTRON PAIR EQUALLYEX BOND BETWEEN HYDROGEN AND OXYGENH2OIONIC BONDSCAN FORM IF TWO ATOMS ARE SO UNEQUAL IN THEIR ATTRACTION FOR VALENCE ELECTRONS THAT ONE ATOM STRIPS AN ELECTRON COMPLETELY FROM THE OTHEREX SODIUM HAS 1 VALENCE ELECTRON AND CHLORINE HAS 7 SO SODIUM TRANSFERS ITS 1 TO CHLORINES 7 AND BOTH ELEMENTS COMPLETE THEIR VALENCE SHELLS16Distinguish between hydrogen bonds and van der Waals interactionsHYDROGEN BONDSFORM WHEN A HYDROGEN ATOM THAT IS ALREADY COVALENTLY BONDED TO ONE ELECTRONEGATIVE ATOM IS ATTRACTED TO ANOTHER ELECTRONEGATIVE ATOMEX THE ELECTRONEGATIVE PARTNERS ARE USUALLY NITROGEN AND OXYGENVAN DER WAALS INTERACTIONSOCCUR BETWEEN TRANSIENTLY POSITIVE AND NEGATIVE REGIONS OF MOLECULES17Define the terms energy potential energy and kinetic energyENERGYTHE ABILITY TO DO WORKPOTENTIAL ENERGYTHE ENERGY THAT MATTER STORES BC OF ITS POSITION OR LOCATIONKINETIC ENERGYTHE ENERGY OF MOTION OBSERVABLE AS THE MOVEMENT OF AN OBJECT PARTICLE OR SET OF PARTICLESChapter 3 Water and the Fitness of the Environment18With the use of a diagram or diagrams explain why water molecules arePolar THE OXYGEN END OF THE WATER MOLECULE HAS A PARTIALLY NEGATIVE CHARGE AND THE HYDROGEN END OF THE WATER MOLECULE HAS A PARTIALLY POSITIVE CHARGEcapable of hydrogen bonding with four neighboring water moleculesTHE SLIGHTLY NEGATIVE CHARGED REGION OF SOME WATER MOLECULES CAN FORM HYDROGEN BONDS WITH THE SLIGHTLY POSITIVE REGIONS OF SURROUNDING WATER MOLECULES2
