Monerans tseem tuaj yeem tsim dua sib deev los ntawm binary fission, txhais tau hais tias ib lub xovtooj tuaj yeem faib nws tus kheej mus rau ob lub hlwb "tus ntxhais" zoo tib yam. Monerans tuaj yeem ncav cuag kev loj hlob hauv lub sijhawm luv luv (kwv yees li kaum tsib feeb), kom lawv tuaj yeem hloov pauv sai sai lossis hloov mus rau qhov chaw hloov pauv.
Monera ua li cas thiaj tsim tau?
Monera reproduces asexually los ntawm binary fission thaum lub sij hawm zoo los yog endospore tsim thaum lub sij hawm tsis zoo. Lawv tsim kev sib deev los ntawm txoj kev hu ua conjugation.
Thaum twg Monera hloov zuj zus?
Tus taxon Monera thawj zaug tau thov los ntawm Ernst Haeckel hauv 1866. Tom qab ntawd, phylum tau nce mus rau qib ntawm lub nceeg vaj hauv xyoo 1925 los ntawm Édouard Chatton. Qhov kawg feem ntau lees txais mega-kev faib tawm nrog cov se Monera yog tsib lub nceeg vaj kev faib tawm uas tsim los ntawm Robert Whittaker hauv xyoo 1969.
Puas Monera ua photosynthesis?
Cov yam ntxwv ntawm Monerans
Ib txhia monerans yog autotrophic, ua lawv tus kheej cov zaub mov los ntawm chemosynthesis, zoo li nitrifying kab mob nyob rau hauv lub voj voog nitrogen, los yog los ntawm photosynthesis, xws li ntshav sulfur kab mob.
Monera rau menyuam yaus yog dab tsi?
Lub Monera Kingdom suav nrog tag nrho cov kab mob nyob hauv ib leeg, suav nrog cov kab mob. Monera yog cov kab mob qub tshaj plaws hauv ntiaj teb; txhua yam muaj sia tsim los ntawm lawv. Monera yog autotrophs, uasua rau lawv tus kheej cov zaub mov, lossis heterotrophs, uas noj autotrophs lossis lwm yam heterotrophs vim lawv ua tsis tau lawv cov zaub mov.

I.e. yog ib qho luv luv rau kab lus id est, uas txhais tau tias "uas yog." I.e. yog siv los rov hais dua ib yam dab tsi uas tau hais yav dhau los txhawm rau kom meej nws lub ntsiab lus. E.g. luv luv rau exempli gratia, uas txhais tau tias "
Leej twg ua bivalves reproduce?
Marine bivalves reproduce by tso tawm cov qe thiab cov phev mus rau hauv dej, qhov chaw fertilization tshwm sim. Cov qe fertilized ces ntab nyob rau saum npoo plankton. Hauv 48 teev tom qab fertilization, lub embryo loj hlob mus rau ib feeb, planktonic, trochophore larvae.
Thaum twg siv polyacrylamide thiab thaum twg agarose?
Agarose gels siv nrog DNA, vim qhov loj ntawm biomolecules (DNA feem ntau yog ntau txhiab kDa). Rau cov protein gels, polyacrylamide muab daws teeb meem zoo, raws li qhov me me me (50 kDa yog qhov raug) zoo dua rau qhov sib txawv ntawm cov gel.
Leej twg qhov twg thaum twg yog vim li cas nug cov lus?
Ib nqe lus nug lossis lo lus nug yog lo lus siv los nug cov lus nug xws li dab tsi, qhov twg, thaum twg, qhov twg, leej twg, leej twg, leej twg, vim li cas, seb thiab ua li cas. Lawv qee zaum hu ua wh-lo lus, vim lus Askiv feem ntau pib nrog wh- (piv Tsib Ws).
Cov tsiaj twg reproduce asexually?
Tsiaj uas yug me nyuam muaj xws liplanarians planarians Qe tsim hauv lub cev thiab muab tso rau hauv cov tshuaj ntsiav. Lub lim tiam tom qab, cov qe tau tsim thiab loj hlob mus rau cov neeg laus. Nyob rau hauv asexual reproduction, tus planarian detaches nws tus Tsov tus tw kawg thiab txhua ib nrab regrows qhov poob qhov chaw los ntawm kev tsim dua tshiab, tso cai rau endoblasts (cov neeg laus qia hlwb) faib thiab sib txawv, yog li ua rau ob kab cab.
