Zog tau dhau mus khoom noj khoom haus los ntawm ib trophic qib mus rau tom ntej. Txawm li cas los xij, tsuas yog kwv yees li 10 feem pua ntawm tag nrho lub zog khaws cia hauv cov kab mob ntawm ib qho trophic qib yog tau kis mus rau cov kab mob nyob rau tom ntej trophic qib . Tus so ntawm lub zog yog siv rau cov txheej txheem metabolic lossis poob mus rau ib puag ncig raws li cua sov.
Ua li no, vim li cas lub zog poob ntawm txhua qib hauv cov khoom noj khoom haus?
Zog txo qis thaum nws txav mus rau trophic qib vim lub zog poob lawm raws li metabolic tshav kub thaum cov kab mob los ntawm ib tug trophic qib yog noj los ntawm kab mob los ntawm lwm yam qib . A saw khoom noj feem ntau tuaj yeem txhawb nqa tsis pub ntau tshaj rau zog hloov ua ntej tag nrho cov zog yog siv.
Kuj Paub, yuav ua li cas thaum lub cev raug tshem tawm ntawm cov khoom noj khoom haus? Thaum a kab mob raug tshem tawm , cov kab mob leej twg noj los yog yos hav zoov lawv yuav txo tau ib co vim lawv poob ib qho zaub mov qhov chaw txawm tias lawv tseem muaj lwm yam zaub mov qhov chaw.
Ntawm no, qhov twg poob zog mus rau hauv cov khoom noj khoom haus?
Tus nqi ntawm zog ntawm txhua qib trophic txo qis thaum nws txav mus los ntawm ib qho ecosystem. Tsawg li 10 feem pua ntawm cov zog ntawm txhua qib trophic yog pauv mus rau qib tom ntej; tus so yog poob Feem ntau los ntawm cov txheej txheem metabolic li cua sov.
Dab tsi cuam tshuam rau ecosystem yog tias ib qib trophic ploj lawm hauv cov khoom noj khoom haus?
Teb: Qhov cuam tshuam ntawm ecosystem yog tias ib qib trophic ploj lawm hauv cov khoom noj khoom haus: cov khoom noj khoom haus ib ntu ntawm cov kab mob nyob hauv cov khoom noj thiab cov khoom noj. zog kis los ntawm ib lub cev mus rau lwm yam kabmob thaum lawv noj lawv.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Ob theem tseem ceeb ntawm photosynthesis yog dab tsi thiab txhua theem tshwm sim nyob qhov twg?
Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent kev tshwm sim thiab lub Calvin voj voog (lub teeb-yooj yim kev xav). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Yuav ua li cas tshwm sim nyob rau hauv txhua ntawm 4 theem ntawm mitosis?
Mitosis yog cov txheej txheem uas cov nucleus ntawm eukaryotic cell faib. Thaum lub sijhawm txheej txheem no, tus muam chromatids cais tawm ntawm ib leeg thiab txav mus rau cov ncej ntawm tes. Qhov no tshwm sim nyob rau hauv plaub theem, hu ua prophase, metaphase, anaphase, thiab telophase
