Thaum Hardy-Weinberg equilibrium tau ntsib cov kab zauv hauv qab no yog qhov tseeb: p2 ua + 2 npq + q2 ua = 1. Qhov twg p2 lus qhov zaus ntawm homozygous dominant genotype, q 2 npe qhov zaus ntawm recessive genotype thiab 2 npq yog qhov zaus ntawm heterozygous genotype.
Ib yam li ntawd, koj tuaj yeem nug, p2 txhais li cas hauv Hardy Weinberg?
Hauv kev sib npaug, p2 ua sawv cev rau qhov zaus ntawm homozygous genotype AA, q2 sawv cev rau qhov zaus ntawm homozygous genotype aa, thiab 2pq sawv cev rau qhov zaus ntawm heterozygous genotype Aa. Tsis tas li ntawd, cov sum ntawm allele frequencies rau tag nrho cov alleles ntawm qhov chaw yuav tsum yog 1, yog li p + q = 1.
Ib tug kuj nug, vim li cas thiaj muaj 2 hauv 2pq? Lub sij hawm p 2 sawv cev rau qhov zaus ntawm homozygotes tseem ceeb (AA) thiab lub sij hawm q 2 sawv cev rau qhov zaus ntawm homozygotes recessive (aa). p sawv cev rau qhov zaus ntawm allele ntawm allele A, thiab q sawv cev rau allele zaus ntawm allele a.
Tom qab ntawd, lo lus nug yog, p2 sib npaug li cas?
P2 yog lub zog los ntawm lub cev muaj zog (shaft effect). P2 yog lub nominal zog ntawm lub cev muaj zog. Qhov txawv ntawm P1 thiab P2 qhia ob qho tib si: kev ua haujlwm ntawm lub cev muaj zog (ηmot.)
Q2 hauv biology yog dab tsi?
q2 ua = recessive allele i.e thaum peb muaj ob 'q' los ntawm niam txiv. thiab 2pq = heterozygote piv txwv li thaum peb tau hais'p' los ntawm ib niam txiv thiab 'q' los ntawm lwm tus niam txiv.

A thiab B sawv cev li cas hauv daim qauv?
Cov ntsiab lus: Standard Form: tus qauv daim ntawv ntawm ib kab yog nyob rau hauv daim ntawv Ax + By = C qhov twg A yog ib tug zoo integer, thiab B, thiab C yog integers. Daim ntawv qauv ntawm ib kab yog lwm txoj hauv kev sau qhov sib npaug ntawm kab
Dab tsi cov tshuaj tiv thaiv sawv cev rau lub cev qhuav dej synthesis?
Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib tug monomer ua ke nrog cov hydroxyl pawg ntawm lwm monomer, tso ib tug molecule ntawm dej. Nyob rau tib lub sijhawm, cov monomers sib koom electrons thiab tsim covalent bonds. Raws li cov monomers ntxiv koom nrog, cov saw hlau ntawm kev rov ua dua monomers tsim ib lub polymer
Cov kws kos duab hu li cas cov duab thiab cov duab siv los sawv cev rau cov yam ntxwv ntawm lub ntiaj teb nto?
Ntiaj Teb Kev Tshawb Fawb - Daim Ntawv Qhia Lub Ntiaj Teb Qhov Nto A B GLOBE Ib puag ncig uas sawv cev rau lub ntiaj teb nto. SCALE Siv los sib piv qhov deb ntawm daim ntawv qhia lossis lub ntiaj teb mus deb ntawm lub ntiaj teb nto. SYMBOLS Ntawm daim duab qhia chaw, cov duab siv los ntawm mapmakers sawv ntsug rau cov yam ntxwv ntawm lub ntiaj teb nto. TSEEM CEEB Ib daim ntawv teev cov cim siv rau ntawm daim ntawv qhia
SFA sawv cev rau dab tsi ntawm lub cev muaj zog?
Service Factor Amps, los yog S.F.A., sawv cev rau tus nqi tam sim no lub cev muaj zog yuav kos thaum khiav ntawm tag nrho Service Factor. Hauv qhov piv txwv nameplate, S.F.A. yog yim amps ntawm 230 volts. Txuas ntxiv tshaj S.F.A. qhia rau ntawm daim ntawv teev npe tuaj yeem ua lub neej luv luv
Koj sawv cev li cas thiab ntau yam?
Lwm txoj hauv kev los txheeb xyuas cov npe thiab ntau qhov kev ua haujlwm yog los ntawm kev siv cov duab. Vim hais tias tus sau hais txog cov txheej txheem ntawm qhov muaj peev xwm nkag tau, lub npe ntawm lub graphconsists ntawm tag nrho cov input qhov tseem ceeb qhia ntawm x-axis. Therange yog cov txheej txheem ntawm cov txiaj ntsig tau tso tawm, uas tau pom ntawm y-axis
