Yog ib tug muaj lub genotype AO, txhais tau tias lawv tau txais A allele los ntawm ib niam txiv thiab O allele los ntawm lwm tus niam txiv, lawv yuav muaj hom A ntshav.

| Hom ntshav | Genotype |
|---|---|
| Hom ntshav A | Genotypes AW or AO |
| Hom ntshav B | Genotypes IB or BO |
| Hom ntshav AB | Genotype AB |
| Hom ntshav O | Genotype OO |
Ntxiv mus, AS genotype yog dab tsi?
Cov noob caj noob ces. Feem ntau, ib tus neeg tau txais ob daim ntawv theej ntawm cov noob uas tsim cov beta-globin, cov protein uas xav tau los tsim cov hemoglobin ib txwm muaj (hemoglobin A, genotype UA). Ib tus neeg uas muaj mob qog noj ntshav tau txais ib qho allele ib txwm muaj thiab ib qho txawv txav ntawm cov kab mob hemoglobin S (hemoglobin) genotype AS).
Tsis tas li ntawd, cov ntshav genotypes yog dab tsi? Qhov txawv tau genotypes AA, AO, BB, BO, AB, OO. Ua li cas ntshav hom muaj feem rau lub rau genotypes ? A ntshav xeem yog siv los txiav txim seb tus yam ntxwv A thiab/lossis B puas muaj nyob hauv a ntshav qauv.
Nyob rau hauv no txoj kev, dab tsi yog qhov zoo tshaj plaws ntshav pab pawg neeg thiab genotype?
Yog tias ib tug neeg muaj ntshav hom A, lawv yuav tsum muaj tsawg kawg ib daim ntawv theej ntawm A allele, tab sis lawv tuaj yeem muaj ob daim ntawv luam. Lawv genotype yog AA lossis AO. Ib yam li ntawd, ib tug uas yog ntshav hom B tuaj yeem muaj genotype ntawm BB lossis BO.
Ntshav hom thiab genotypes ?
| Hom ntshav | Muaj peev xwm genotypes |
|---|---|
| A | AW AO |
| B | BB IB |
Dab tsi yog 3 hom genotypes?
Muaj peb muaj genotypes , PP (homozygous dominant), Pp (heterozygous), thiab pp (homozygous recessive). Tag nrho peb muaj txawv genotypes tab sis thawj ob muaj tib yam phenotype (liab ntshav) raws li qhov txawv ntawm peb (dawb).

Dab tsi yog qhov tseem ceeb ntawm cov kab mob hauv cov ntshav?
Ntshav. Tib neeg cov ntshav muaj cov tsis muaj carbonic acid (H 2CO 3) thiab bicarbonate anion (HCO 3 -) txhawm rau tswj cov ntshav pH ntawm 7.35 thiab 7.45, raws li tus nqi siab dua 7.8 lossis qis dua 6.8 tuaj yeem ua rau tuag taus
Dab tsi yog qhov extracellular matrix ntawm cov ntshav?
Lub extracellular matrix, hu ua plasma, ua rau cov ntshav tshwj xeeb ntawm cov ntaub so ntswg vim nws yog kua. Cov kua dej no, uas feem ntau yog dej, perpetual suspends tsim cov ntsiab lus thiab ua rau lawv mus thoob plaws hauv lub cev nyob rau hauv lub plawv system
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog genotype ntawm tus neeg uas muaj kab mob ntshav qab zib?
Feem ntau, ib tus neeg tau txais ob daim ntawv theej ntawm cov noob uas tsim cov beta-globin, cov protein uas xav tau los tsim cov hemoglobin ib txwm muaj (hemoglobin A, genotype AA). Ib tus neeg uas muaj mob qog noj ntshav tau txais ib qho allele ib txwm muaj thiab ib qho txawv txav ntawm cov kab mob hemoglobin S (hemoglobin genotype AS)
