Apomictic cov txheej txheem mimic ntau ntawm cov xwm txheej ntawm kev sib deev kev sib deev thiab ua rau cov noob fertile. Ib qho tseem ceeb sib txawv yog qhov apomictic embryo yog muab tau los ntawm cov hlwb nyob rau hauv cov ntaub so ntswg niam ovule es tsis yog los ntawm fusion ntawm txiv neej thiab poj niam gametes.
Ntawm no, Apomictic noob yog dab tsi?
Apomixis yog asexual ntau lawm noob yog li ntawd apomictic noob yog clones ntawm niam nroj tsuag. Kev tsim khoom siv tau noob tsis muaj pollination lossis fertilization yog hu ua apomixis . Cov no noob yog tsim los ntawm paj, ib yam li niaj zaus noob , tab sis tsis muaj paj ntoos koom nrog.
Ib yam li ntawd, yuav ua li cas Apomictic noob raug tsim? Apomixis (txiv neej noob tsim ) yog qhov tshwm sim ntawm cov nroj tsuag tau txais lub peev xwm los hla qhov tseem ceeb tshaj plaws ntawm kev sib deev kev sib deev: meiosis thiab fertilization. Yog tsis xav tau txiv neej fertilization, qhov tshwm sim noob germinates ib tsob nroj uas loj hlob raws li ib tug niam clone.
Ntxiv mus, Apomixis yog dab tsi nrog piv txwv?
Apomixis yog ib qho kev yug me nyuam uas tshwm sim tsis muaj fertilization thiab tsis cuam tshuam nrog meiosis. Ib piv txwv ntawm apomixis yog cov apomictic parthenogenesis. Nws yog ib qho uas lub qe qe tsim los ntawm mitosis. Tom qab ntawd nws loj hlob ncaj qha mus rau hauv lub embryo yam tsis muaj fertilization ua ntej.
Puas yog Apomictic embryo clones?
Raws li cov no embryo yog los ntawm ib leeg niam cell, lawv cov caj ces zoo ib yam li niam cell. Clones txhais tau tias yog cov kab mob sib xws, yog li, apomictic embryo tuaj yeem hu ua clones ntawm lawv niam ib yam li lawv caj ces zoo ib yam li lawv niam cell.

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 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 yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Puas yog embryo yog ib tus neeg?
Ib tug neeg tsim tshiab feem ntau hu ua embryo kom txog rau thaum cuaj lub lim tiam tom qab xeeb tub (saib tib neeg embryogenesis), thaum nws raug hu ua fetus. Hauv lwm cov kab mob sib txawv, lo lus "embryo" tuaj yeem siv dav dua rau txhua qhov kev loj hlob thaum ntxov lossis lub neej voj voog theem ua ntej yug los yog hatching
