Cov tsos ntawm ob pronuclei yog thawj lub cim ntawm kev ua tiav fertilization raws li pom thaum lub sij hawm nyob rau hauv vitro fertilization, thiab yog feem ntau pom 18 teev tom qab insemination lossis ICSI. Lub zygote yog ces hu ua ob-pronuclear zygote ( 2 PIB ).
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog 1pn embryo?
2.3 Embryo kab lis kev cai 2PN tau txhais tias muaj ob qho kev sib txawv ntawm cov pronuclei thiab ob lub cev polar. 1 PIB txhais tau hais tias muaj tsuas yog ib tug pronucleus thiab ob lub cev polar. 0PN tau txhais tias yog qhov tsis muaj pronuclei thiab muaj ob lub cev polar.
Tsis tas li ntawd, txiv neej Pronucleus yog dab tsi? Kev kho mob txhais ntawm Pronucleus Cov txiv neej pronucleus yog cov phev nucleus tom qab nws nkag mus rau hauv ovum ntawm fertilization tab sis ua ntej fusion nrog poj niam pronucleus . Ib yam li ntawd, poj niam pronucleus yog lub nucleus ntawm lub zes qe menyuam ua ntej fusion nrog cov txiv neej pronucleus.
Yog li ntawd, yog vim li cas tsis zoo embryo zoo?
Muaj ntau qhov ua rau suav nrog cov txheej txheem stimulation tsis tsim nyog thiab nws qhov kev ua tiav, cov xwm txheej tsis zoo hauv chav kuaj embryology, lub voj voog tshwj xeeb cov lus teb tsis zoo, cov caj ces txawv txav hauv gametes ntawm tus txiv neej lossis poj niam tus khub, lossis kev hloov pauv caj ces hauv lub cev. lub embryo.
Lub embryo zoo li cas txiav txim siab?
Cov ntawv qhia txog qhov zoo ntawm ICM thiab TE. Cov qhab nia zoo ib yam li cov qhab nia uas koj tau txais hauv tsev kawm ntawv: A yog qhov zoo heev zoo , B zoo zoo , C yog ncaj ncees zoo , thiab D yog pluag zoo . Feem ntau, pluag zoo cleavage theem embryo muaj ob peb lub hlwb thiab ntau fragmentation.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
