Nws yog tseem ceeb rau tib neeg rau nkag siab txog kab mob kev sib txuas lus kom lawv nrhiav tau txoj hauv kev los ua tshuaj tua kab mob uas cuam tshuam rau qhov phem kab mob kev sib txuas lus system, tso cai rau kab mob kom tsis paub tias muaj pes tsawg tus ntawm lawv muaj.
Xav txog qhov no, vim li cas cov kab mob yuav tsum sib txuas lus?
Cov kab mob sib txuas lus nrog ib leeg siv tshuaj teeb liab molecules. Txoj kev no, hu ua quorum sensing, tso cai kab mob saib xyuas ib puag ncig rau lwm tus kab mob thiab hloov tus cwj pwm ntawm cov pej xeem thoob plaws hauv kev teb rau kev hloov pauv ntawm tus lej thiab / lossis hom muaj nyob hauv zej zog.
Qhov thib ob, Vibrio fischeri sib txuas lus li cas tshwm sim los ntawm lawv cov kev sib txuas lus? Vibrio fischeri sib txuas lus los ntawm kev zais me me molecules ua ke. Lawv glow li ib tshwm sim ntawm lawv kev sib txuas lus . Nws yog ib qho tseem ceeb rau tib neeg vim yog peb to taub yuav ua li cas lub hlwb sib txuas lus ces peb tuaj yeem tua lawv ua ntej lawv tawm tsam lawv tus tswv tsev.
Ntxiv mus, koj puas xav tias cov kab mob tuaj yeem sib txuas lus?
Cov kab mob tuaj yeem tham nrog ib leeg ntawm molecules lawv tus kheej tsim. Qhov tshwm sim yog hu ua quorum sensing, thiab tseem ceeb heev thaum tus kab mob propagates. Cov kab mob tuaj yeem tham nrog ib leeg ntawm molecules lawv tus kheej tsim. Qhov tshwm sim yog hu ua quorum sensing, thiab tseem ceeb heev thaum tus kab mob propagates.
Vim li cas cov kws tshawb fawb kawm txog cov kab mob sib txuas li cas?
Cov kab mob sib txuas lus los ntawm cov txheej txheem tshuaj hu ua quorum sensing, nyob rau hauv uas lawv tso tawm molecules uas ua hauj lwm raws li cov lus pom nyob ze kab mob . “Lub hom phiaj kawg ntawm qhov kev tshawb fawb no yog hloov pauv pawg neeg paub txog txoj hauv kev uas ua kom puas tsuaj kab mob , thiab cov txiaj ntsig xav tau kab mob ."

Vim li cas nws tseem ceeb uas peb txoj kev nkag siab txog kev tshawb fawb txog kev sib raug zoo txuas ntxiv mus?
Kev nthuav dav thiab kev loj hlob ntawm kev tshawb fawb txog kev sib raug zoo yog qhov tsim nyog vim nws pab txhawb koj txoj kev sib raug zoo thiab kev sib raug zoo nrog cov neeg hauv zej zog. Thaum koj nyob nrog cov neeg koj yuav tsum nkag siab lawv thiab social science pab koj ua li ntawd
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Dab tsi yog qhov txawv ntawm kev nkag siab dav dav BSH thiab kev nkag siab nqaim NSH?
12) Dab tsi yog qhov txawv ntawm qhov dav-sensitive heritability (BSH) thiab nqaim-sense heritability (NSH)? A) BSH yog ib qho kev ntsuas ntawm cov noob uas cuam tshuam rau qhov zoo, thaum NSH yog ib qho kev ntsuas ntawm cov noob nrog cov teebmeem loj. B) NSH muaj feem xyuam rau ib leeg-gene yam nkaus xwb
Vim li cas kev nkag siab txog noob caj noob ces tseem ceeb rau cov tub ntxhais kawm?
Vim li cas kev kawm noob caj noob ces tseem ceeb? Nyob rau yav tom ntej, cov kws kho mob thiab cov kws tshawb fawb vam tias yuav siv peb cov ntaub ntawv caj ces los kuaj, kho, tiv thaiv thiab kho ntau yam mob. Cov noob yog cov lus qhia, uas qhia koj lub cev yuav ua li cas ua kom tag nrho cov proteins nws xav tau kom muaj sia nyob thiab loj hlob
Vim li cas nws tseem ceeb kom nkag siab txog tus cwj pwm ntawm cov pa roj?
Txoj kev kawm ntawm cov pa roj tso cai rau peb kom nkag siab txog tus cwj pwm ntawm qhov teeb meem ntawm nws qhov yooj yim tshaj plaws: cov khoom ntawm tus kheej, ua haujlwm ntawm nws tus kheej, yuav luag tsis yooj yim los ntawm kev sib cuam tshuam thiab kev cuam tshuam ntawm ib leeg
