Q: Listl thel 7l mostl widelyl acceptedl characteristicsl ofl livingl organisms.
Answer:
1)l Order,l (2)l Evolutionaryl Adaptation,l (3)l Regulation,l (4)l Energyl Processing,l (5)l Growthl andl Development,l (6)l Responsel tol thel Environment,l andl (7)l Reproduction.
Q: Describel evolutionaryl adaptationl andl givel anl example.
Answer:
refersl tol smaller,l geneticl changesl thatl allowl forl betterl survivall ofl anl organism.l Forl instance,l considerl camouflage.l Animalsl thatl arel properlyl camouflagedl withinl theirl givenl environmentl will,l theoretically,l survivel longerl andl canl thusl reproducel more.l Coatl (suchl asl fur)l colorl genesl withl thel greatestl survivall ratel willl bel strengthenedl andl amplifiedl withinl thel population.
Q: Whatl isl anl adaptation?l Whatl characteristicl ofl lifel wouldl anl adaptationl falll into?
Answer:
Anl adaptionl isl al changel orl al processl thatl allowsl anl organisml tol becomel betterl suitedl forl theirl environment.l Theyl canl bel physicall orl behavioral.l Forl example,l al crab'sl hardl shelll isl al physicall adaption,l whilel al squirrell hibernatingl throughl thel winterl isl al behaviorall adaption.l Thisl fallsl intol Responsel tol thel Environment.

Q: Comparel andl contrastl sexuall andl asexuall reproduction.
Answer:
Sexuall reproductionl involvesl thel fusionl ofl twol gametesl (onel froml eachl parent)l thatl willl unitel andl growl intol al newl offspring.l Asexuall reproduction,l inl contrast,l givesl risel tol newl offspringl froml al singlel organism.
Q: Al groupl ofl onel particularl speciesl livingl withinl definedl boundariesl ofl al communityl
bestl describesl a(n):
Answer:
Population
Q: Al systeml ofl livingl andl non-livingl thingsl inl al regionl bestl describesl a(n):
Answer:

Q: Whatl arel thel 3l domainsl thatl comprisel thel Linnaeanl Classificationl system?
Answer:
1)l Archaea,l (2)l Eubacteria,l andl (3)l Eukarya
Q: Whatl isl thel purposel ofl al phylogenicl tree?
Answer: 2 / 4
Al phylogenicl treel isl al branchingl diagraml thatl showsl thel relationshipl betweenl differentl levelsl ofl Linnaeanl classificationl taxa.l Phylogenicl treesl providel al visuall representationl ofl dichotomiesl concerningl evolutionaryl relationshipsl andl enablesl scientistsl tol unitel phylogenyl withl thel classicl Linnaeanl classificationl systems.l Eachl branchl pointl representsl wherel thel twol organismsl likelyl sharel al commonl ancestor.
Q: Truel orl False:l Extremophilesl arel al smalll sub-setl ofl thel Archaeal domainl thatl livel inl extremel environments.
Answer:
true
Q: Bacterial thatl neitherl benefitsl froml norl harmsl itsl hostl andl arel oftenl partl ofl thel
humanl floral arel considered:
Answer:
Commensal
Q: Bacterial thatl causel illnessl arel considered:
Answer:
Pathogenic
Q: Describel whatl anl exotoxinl isl andl givel anl example.
Answer:
Exotoxinsl arel proteinsl thatl arel secretedl byl thel bacteriall cell.l Vibriol choleral isl anl example
- / 4
Q: Describel whatl anl endotoxinl isl andl givel anl example.
Answer:
Endotoxinsl arel presentl insidel thel celll orl canl bel thel lipopolysaccharidel componentsl ofl thel outerl membranel ofl somel bacterial (Gram-negative).l Importantly,l thesel toxinsl arel onlyl releasedl uponl thel deathl ofl thel bacteriall celll whenl thel celll walll beginsl tol decompose.l Salmonellal isl anl example.
Q: Describel whatl al symbioticl relationshipl looksl likel betweenl twol organisms.
Answer:
Al symbioticl relationshipl isl al long-terml relationshipl betweenl twol organismsl inl whichl onel orl bothl organismsl benefitl froml thel pairedl interaction.
Q: Whatl arel thel 4l mainl Eukaryotel Kingdoms?
Answer:
(1)l Fungi,l (2)l Protista,l (3)l Plantae,l andl (4)l Animalia
Q: Describel thel processl ofl binaryl fissionl andl statel whetherl itl isl al forml ofl sexuall orl asexuall reproduction.
Answer:
Binaryl fissionl isl thel processl ofl reproductionl wherel thel parentl bodyl isl seeminglyl pinchedl intol twol halves,l resultingl inl twol daughterl organismsl eachl withl itsl ownl nuclei.l Thisl isl anl examplel ofl asexuall reproduction.
