Volvox yog cov protists uas nyob hauv cov cheeb tsam, los yog pab pawg ntawm cov kab mob nyob ua ke. Lawv yog ob qho tib si autotrophs thiab heterotrophs. Lawv siv lawv lub qhov muag pom lub teeb thaum lawv raug photosynthesis. Lawv kuj muaj tails, los yog flagella, lawv siv los txav lub colony.
Ua raws li qhov xav tau, lub hom phiaj ntawm Volvox yog dab tsi?
Sau npe hnub no. Volvox tuaj yeem pom hauv pas dej, pas dej, thiab lub cev ntawm cov dej tshiab thoob plaws ntiaj teb. Raws li autotrophs, lawv pab txhawb kev tsim cov pa oxygen thiab ua zaub mov rau ntau cov kab mob hauv dej, tshwj xeeb tshaj yog cov kab mob hauv lub cev hu ua rotifers. Ib qho ntawm feem ntau hom, V.
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov tseeb nthuav txog Volvox? Volvox tsis muaj dab tsi tab sis chlorophyte los yog ntsuab algae uas tshwm sim raws li ib tug loj spherical colony. Txhua me algae nyob rau hauv lub cheeb tsam tuav ob flagella, nplawm-zoo li cov plaub hau. Cov flagella ua zoo li tails thiab pab lawv txav mus los hauv dej. Nws yog nthuav saib cov spinning txav ntawm volvox ua hauv qab dej.
Hauv qhov no, Volvox pab tau tib neeg li cas?
Volvox tsis muaj teeb meem rau tib neeg , (lawv tsis muaj co toxins ua rau koj mob), tab sis lawv tsim algae blooms uas tuaj yeem ua mob rau lub ecosystem.
Volvox yug me nyuam li cas?
Volvox yog facultatively kev sib deev thiab tau yug me nyuam ob leeg kev sib deev thiab asexually. Ib qho asexual colony suav nrog ob leeg somatic (vegetative) hlwb, uas ua tsis yog yug me nyuam , thiab loj, uas tsis yog-motile gonidia nyob rau hauv sab hauv, uas tsim cov colonies tshiab los ntawm kev rov faib dua.

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 ntawm Endomycorrhizae ua Glomeromycetes muaj thiab dab tsi tshwj xeeb txog nws?
Glomeromycetes tsim mycorrhizae. Txawm li cas los xij, lawv yog ib pab pawg tseem ceeb ntawm kev lag luam. Tag nrho cov glomeromycetes tsim symbiotic mycorrhizae nrog cov cag ntoo. Mycorrhizal fungi tuaj yeem xa cov phosphate ions thiab lwm yam minerals rau cov nroj tsuag. Hauv kev sib pauv, cov nroj tsuag muab cov fungi nrog cov organic as-ham
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
S sawv rau dab tsi thiab dab tsi tshwm sim hauv theem no?
S theem sawv rau 'Synthesis'. Qhov no yog theem thaum DNA replication tshwm sim. The G2 stage stands for 'GAP 2'
