Ntuj zaub kev nthuav tawm tshwm sim thaum lub axillary bud hlob mus rau hauv ib tug lateral tua thiab tsim nws cov hauv paus hniav (tseem hu ua adventitious keeb kwm). Cov qauv cog cia ntuj zaub kev nthuav tawm muaj xws li qhov muag teev, rhizomes, stolons thiab tubers.
Hauv qhov no, dab tsi yog qhov kev tsim tawm ntawm ntuj tsim?
Artificial kev yug me nyuam yog lub creation ntawm lub neej tshiab los ntawm lwm yam tshaj li ntuj txhais tau tias muaj nyob rau hauv lub cev. Piv txwv li muaj xws li kev siv tshuaj tua kab mob, hauv vitro fertilization, cloning thiab embryonic splitting, los yog cleavage.
Qhov thib ob, 2 hom kev nthuav tawm yog dab tsi? Muaj ob pawg ntawm cov nroj tsuag propagation: asexual thiab kev sib deev. Asexual propagation yog siv los tswj kev xaiv ntawm tus kheej paub thiab zoo thiab suav nrog cov txheej txheem xws li kev faib, huab cua- txheej txheej , grafting thiab cuttings.
Nyob rau hauv no hais txog, dab tsi yog ntuj propagation thiab dag propagation?
Artificial Methods of Vegetative Kev nthuav tawm . Muaj ob txoj hauv kev nthuav tawm cog vegetatively: ntuj thiab dag . Cov nroj tsuag no muaj xws li: qhov muag teev thiab qhov muag teev, cloves, corms thiab cormels, tubers thiab tubercles, tuberous cag, rhizomes, runners, stolons, slips, suckers, crown thiab plantlets.
Dab tsi yog cov txiaj ntsig ntawm kev cog qoob loo?
Qhov zoo ntawm kev sib deev Kev nthuav tawm :- Hybrid noob tuaj yeem tsim los ntawm txoj kev no. Tshiab ntau yam ntawm cov qoob loo yog tsim los ntawm kev sib deev txoj kev ntawm kev nthuav tawm . Hauv paus Tshuag rau budding thiab grafting tuaj yeem tsa los ntawm txoj kev no. Cov nroj tsuag propagated los ntawm txoj kev no yog nyob ntev thiab muaj peev xwm tiv taus dej ntxhov siab.

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
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
