Hydrosere yog ib qho kev cog qoob loo nyob rau hauv uas qhib dej tshiab ib txwm qhuav tawm, tsis tu ncua los ua swamp, marsh, thiab lwm yam thiab hauv hav zoov kawg. Xeroser yog kev vam meej ntawm cov zej zog ib puag ncig uas tshwm sim hauv thaj chaw qhuav qhuav xws li cov suab puam xuab zeb, xuab zeb dunes, ntsev suab puam lossis pob zeb suab puam.
Xav txog qhov no, Hydrosere succession yog dab tsi?
A hydrosere yog tsob ntoo kev vam meej uas tshwm sim nyob rau hauv ib cheeb tsam ntawm cov dej tshiab xws li nyob rau hauv lub pas dej oxbow thiab kettle pas dej. Nyob rau tib lub sijhawm, thaj chaw qhib dej tshiab yuav qhuav tawm, thaum kawg ua ntoo. Thaum lub sijhawm hloov pauv no, ntau hom av sib txawv xws li swamp thiab marsh yuav ua tiav ib leeg.
Ib sab saum toj, qhov twg hauv qab no yog thawj theem ntawm Hydrosere? 1. Phytoplankton Theem : Nws yog tus pioneer theem ntawm hydrosere . Spores ntawm no theem ncav cuag lub cev dej los ntawm cua los yog tsiaj. Cov ua ntej tshwm sim yog feeb autotrophic kab mob hu ua phytoplankton, piv txwv li, diatoms, ntsuab flagellates, ib leeg-celled colonial los yog filamentous ntsuab algae nrog rau xiav-ntsuab algae.
Yog li ntawd, qhov twg Xerosere succession tshwm sim?
Xeroser yog ib tsob ntoo kev vam meej uas yog txwv los ntawm kev muaj dej. Nws suav nrog cov theem sib txawv hauv xerarch kev vam meej . Xerarch kev vam meej ntawm cov zej zog ecological originated nyob rau hauv qhov xwm txheej qhuav heev xws li xuab zeb deserts, xuab zeb dunes, ntsev suab puam, pob zeb suab puam thiab lwm yam.
Dab tsi yog 4 theem ntawm lub pas dej ua ke?
Teb Cov Kws Paub Tseeb. Cov plaub theem ntawm lub pas dej ua ke yog pas dej pioneers, submergent nroj tsuag tshwm nyob ib ncig ntawm lub pas dej , decaying teeb meem raising thepond pem teb thiab ib tug marsh raug tsim. Lub pas dej yog cov qhov ntiav uas cov dej sau. Lawv yog tsim los ntawm geological txheej xwm.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Qhov txawv ntawm Hydrosere thiab Xerosere yog dab tsi?
Hydrosere yog cov nroj tsuag kev loj hlob nyob rau hauv uas qhib dej tshiab ib txwm dries tawm, tsis tu ncua los ua swamp, marsh, thiab lwm yam thiab nyob rau hauv kawg woodland. Xerosere yog qhov kev vam meej ntawm ib puag ncig cov zej zog uas tshwm sim hauv thaj chaw qhuav qhuav xws li cov suab puam xuab zeb, xuab zeb dunes, ntsev suab puam lossis pob zeb suab puam
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
