Fucus yog xim av alga uas ua raws lub voj voog lub neej diplontic. Ectocarpus kelps muaj lub neej voj voog haplo-diplontic. Gametic meiosis tshwm sim hauv lub voj voog lub neej diploid.
Yuav pom qhov twg hauv qab no zygotic meiosis tuaj yeem pom?
(d) Zygotic meiosis yog sawv cev hauv lub voj voog lub neej haplontic ntawm ntau cov algae suav nrog Chlamydomonas Nyob rau hauv lub neej voj voog, txhua lub hlwb yog haploid tsuas yog zygote. Qhov no yog vim meiosis tshwm sim hauv zygote nws tus kheej ua rau plaub lub hlwb haploid uas ua rau cov nroj tsuag hapolid.
Puas zygotic meiosis tshwm sim hauv Fucus?
Zygotic meiosis yog tus yam ntxwv ntawm a) Fucus b) Funaria c) Marchantia d) Chlamydomonas. Hauv zygotic meiosis, meiotic division tshwm sim hauv zygote uas ua rau muaj kev loj hlob ntawm cov neeg haploid. Thallophytes muaj qhov tseem ceeb gametophytic tiam i.e., qhov sib thooj ntawm cov neeg haploid.
Puas zygotic meiosis tshwm sim hauv spirogyra?
Yog li ntawd, ntsuab algae uas yog tus Spirogyra nkag mus rau zygotic meiosis. Li no, lo lus teb raug yog kev xaiv (B).
Nyob hauv cov kab mob twg hauv qab no zygote nkag mus rau meiosis?
Ob kab mob ntawm kev sib deev tawm tsam pab txhawb lawv cov gametes haploid los ua ib tug diploid zygote. Lub zygote dhau mus meiosis tam sim ntawd tsim plaub haploid hlwb. cov hlwb no raug mitosis los tsim cov kab mob.

Nyob rau hauv endochondral ossification dab tsi tshwm sim rau cov chondrocytes?
YNyob rau hauv endochondral ossification, ua li cas rau cov chondrocytes? Lawv tuag nyob rau hauv lub calcified matrix uas nyob ib puag ncig lawv. Lawv pab pawg ua ke los tsim thawj qhov chaw ossification chaw ossification chaw Ib qho chaw ossification yog ib qho chaw uas ossification ntawm pob txha mos pib Thawj kauj ruam hauv ossification yog tias cov pob txha mos ntawm lub sijhawm no nthuav dav thiab npaj lawv tus kheej hauv kab.
Cov khoom qab zib liab nyob rau hauv cov khoom qab zib nyob qhov twg?
Cov Candies liab tsuas yog muaj nyob rau qib nrog 5 lossis 6 xim. Yog li ntawd lawv tsis tshwm sim rau txhua qib. Qhov ntau xim cov qib muaj, qhov nyuaj nws feem ntau yog. Nyob zoo @BBehr . Qib nyuaj tshaj hauv Candy Crush yog dab tsi?
Nyob hauv paj ntoo protandry tshwm sim nyob rau hauv?
1. Qhov xwm txheej hauv uas tus txiv neej lub cev xeeb tub (stamens) ntawm lub paj loj hlob ua ntej cov poj niam (carpels), yog li ua kom nws tus kheej fertilization tsis tshwm sim. Piv txwv ntawm cov paj protandrous yog ivy thiab rosebay willowherb .
Cov siphons tshwm sim thiab tshwm sim nyob qhov twg?

Nyob rau hauv photorespiration decarboxylation tshwm sim nyob rau hauv uas organelle?
decarboxylation yog ib kauj ruam ntawm krebs voj voog, uas tshwm sim hauv mitochondria . Dab tsi organelle koom nrog hauv photorespiration? Photorespiration suav nrog peb lub cev ( chloroplasts, peroxisomes, thiab mitochondria), txhua tus muaj cov txheej txheem thauj tshwj xeeb rau lub voj voog nruab nrab .
