Meiosis tshwm sim hauv cov kab mob haploid kuj. Kev piav qhia: Haploid yog ib yam mob uas cov hlwb muaj ib txheej (N) ntawm chromosomes. Tab sis, nyob rau hauv tsawg zaus, meiosis tshwm sim hauv cov kab mob haploid kuj, ob haploid cov hlwb ua ntej fuse ua ke los ua diploid zygote thiab tom qab ntawd nkag mus meiosis.
Kuj paub yog, qhov no puas txhais tau tias meiosis yeej tsis tshwm sim hauv kab mob haploid?
Nyob zoo cov tub ntxhais kawm, Meiosis kuj tseem hu ua kev faib txo qis vim nws txo cov chromosomes hauv a diploid tus kheej mus rau ib nrab los yog haploid tus lej. Thaum ib kab mob xa muaj haploid tus naj npawb ntawm chromosomes, ces tsis tas yuav tsum tau meiosis rau tshwm sim.
Tsis tas li ntawd, nyob rau theem twg meiosis tshwm sim hauv cov kab mob haploid? Teb: Meiosis ua tau coj qhov chaw tsuas yog nyob rau hauv ib tug diploid theem (tom qab zygotic theem ) vim hais tias lub zygote yog tib lub cell diploid nyob rau hauv lub neej voj voog ntawm xws li kab mob . Qhov no meiosis ib cas cov kab mob haploid yuav tshwm sim ntawm fertilization.
Kuj Paub, cov kab mob haploid puas raug meiosis?
Yog lawm, cov kab mob haploid kuj muaj a meiosis nyob rau hauv lawv lub neej voj voog. Feem ntau diploid kab mob nkaus xwb nyob rau hauv meiosis . Tab sis nyob rau hauv ib co cov kab mob haploid tab tom ua kev sib deev kev sib deev, rau haploid gametes fuse ua rau lub diploid zygote. Lub zygote ntawd nyob rau hauv meiosis tsim tawm lub cev haploid.
Meiosis tshwm sim nyob qhov twg hauv kab mob?
Teb thiab piav qhia: Meiosis siv qhov chaw nyob rau hauv lub cev xeeb tub ntawm lub kab mob . Rau cov poj niam, meiosis yuav siv qhov chaw nyob rau hauv lub zes qe menyuam, qhov twg cov qe raug tsim thiab
Pom zoo:
Cov kab mob puas kis cov kab mob eukaryotic?
Ib lub cell uas muaj kab mob ua rau cov kab mob kis tau ntau dua thiab cov khoom siv caj ces es tsis yog nws cov khoom qub. Qee cov kab mob yuav nyob twj ywm hauv cov tswv tsev rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv cov tswv tsev (ib theem hu ua lysogenic theem). Cov kab mob ua rau muaj ntau yam kab mob hauv eukaryotes
Thaum lub sij hawm geological twg puas tau cov kab mob thawj zaug tshwm sim hauv ntiaj teb?
Nyob ze rau qhov kawg ntawm lub sijhawm no, kwv yees li 2.7 txog 2.9 billion xyoo dhau los, raws li Blank, stromatolites, cov kab mob ntawm cov kab mob uas siv photosynthesis los tsim lub zog yam tsis muaj oxygen, thawj zaug tshwm sim
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
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
