BIOLOGY EXAM- WINTER WITH
APPROPRIATE RESPONCES

Ecology z- zCORRECT✅✅study zof zhow zorganisms zrelate zto zone zanother zand zto
ztheir zenvironments


Population z- zCORRECT✅✅group zof zindividuals zof zthe zsame zspecies zthat zlive zin
zthe zsame zarea


Ecosystem z- zCORRECT✅✅a zcommunity zplus zthe zphysical zenvironment

Community z- zCORRECT✅✅more zthan zone zspecies zin zthe zsame zarea

what zdoes zthe zabiotic zenvironment zconsit zof? z- zCORRECT✅✅- ztemperature
- zwater
- zsunlight z
- zsoil

how zdo zhomeothermic zorganisms zmaintain zhomeostasis? z- zCORRECT✅✅-
zbehaviour: zimitation, zinstinct, zmoving zfrom zone zhabitat zto zanother z(reptile),
zmaintain zbody ztemp
ectotherms zand zendotherms

true zor zfalse: zHomeostasis zcan zbe zmaintained zbehaviour, zphysiological zor
zmorphological zplasticity, zor zevolutionary zadaptation z- zCORRECT✅✅true


what zmust zbeetles zcollect zto zhelp zlive zin za zdry zenvironment? z-
zCORRECT✅✅water


Plasticity z- zCORRECT✅✅organisms zor zcells zcan zmodify ztheir zphenotypes zin
zresponse zto zthe zenvironment


is zplasticity ztransmitted zto zthe znext zgeneration? z- zCORRECT✅✅no, zthey're znot
zencoded zfor zby zgenes


examples zof zphysiological zplasticity z- zCORRECT✅✅- zhiking zmount zeverest:
zincrease zin zred zblood zcells, zbut zwill znot zbe zpassed zdown zto zgeneration zby zgenes


examples zof zmorpholgical zplasticity z- zCORRECT✅✅when zyou zchange zyour
zgenes zbased zon zyour zenvironment
- zzooplankton zgrow zspikes znot zto zbe zeaten
- zthick zfur zcoats zon zanimal zduring zthe zwinter

, true zor zfalse: zevolutionary zadaption zleads zto zgenetic zresponses z-
zCORRECT✅✅true


what zwas zAllen's zrule zof zreduced zsurface zarea? z- zCORRECT✅✅Mammals zfrom
zcolder zclimates zhave zshorter zears zand zlimbs zsince zthere zwould zbe zless zsurface
zarea zneeded zto zradiate zheat zto ztheir znon zexisting zlong zlimbs zand zthey zwould
zhave zthe zability zto zmaintain zwarmth


whats zanother zexample zof zevolutionary zadaption? z- zCORRECT✅✅in zthe zsouth
zare zfound zgiraffes zand zelephants zthat zhave zlong zlimbs


what zare zthe zthree zcharacteristics zof zpopulation zecology? z- zCORRECT✅✅-
Population zrange
-Pattern zof zspacing zof zindividuals z
-How zpopulation zchanges zin zsize zthrough ztime

what zdoes zendemic zmean? z- zCORRECT✅✅a zspecies zthat zis zfound zonly zin zone
zplace z
eg: zpolar zbears zwould znot zbe zfound zin zthe ztropic zbut zin zthe zcold

true zor zfalse: zRanges zchange zthrough ztime z- zCORRECT✅✅true z, zclimate zchange
z(sharks zmigrating ztowards zcape zBreton zeven zthough zthe zwaters zcold)


what zare zthe ztypes zof zspacing zpatterns? z- zCORRECT✅✅- zrandom: zrandom
zspacing zsince zno zinteractions z(bottom zof zocean)
- zuniform: zevenly zspaced z(penguins) z
- zclumped: zdistributed zin zclusters z(school zfish)

Demography z- zCORRECT✅✅Quantitative zstudy zof zpopulations

How zdo zwe zsample zpopulations? z- zCORRECT✅✅1. zquadrat: zsquare zon zgrass
2. zcapture zand zrecapture: ztagging zsharks zocearch z(used zfor zmoving zanimals)

Generation ztimes z- zCORRECT✅✅average zinterval zbetween zbirth zof zan zindividual
zand zbirth zof zits zoffspring


fecundity z- zCORRECT✅✅number zof zoffspring zproduced zin za zstandard ztime

Cohort z- zCORRECT✅✅A zgroup zof zindividuals zof zthe zsame zage

what zare zthe z3 ztypes zof zsurvivorship? z- zCORRECT✅✅Type zI: zhigh zsurvivorship
z(human)
Type zII: zconstant zsurvivorship z(hydra)
Type zIII: zhigh zmortality zrate z(oyster)
