Dab tsi txiav txim siab tus naj npawb ntawm phenotypes rau a muab qhov zoo ? Cov tus lej ntawm cov noob uas tswj cov qhov zoo . Cov yam ntxwv tswj los ntawm ob lossis ntau lub noob. Ntau ua tau genotypes thiab txawm ntau phenotypes vim muaj ob los yog ntau tshaj alleles.
Tib neeg kuj nug, dab tsi txiav txim siab tus naj npawb ntawm cov phenotypes rau ib qho zoo?
Cov tus naj npawb ntawm phenotypes ua rau a qhov zoo nyob ntawm ntau npaum li cas noob tswj cov qhov zoo . Ib tug noob qhov zoo yog a qhov zoo tswj los ntawm ib lub noob nkaus xwb. Tib-gene yam ntxwv tej zaum yuav muaj ob lossis peb qhov txawv phenotypes.
Ib yam li ntawd, muaj pes tsawg tus phenotypes tuaj yeem ua tau nrog tib lub noob zoo? Cov yam ntxwv tswj los ntawm a ib gene nrog ntau tshaj ob alleles hu ua ntau allele yam ntxwv . Ib qho piv txwv yog ABO hom ntshav. Muaj peb hom alleles rau qhov no qhov zoo , uas tuaj yeem sawv cev los ntawm cov tsiaj ntawv A, B, thiab O. Raws li qhia hauv Table hauv qab no, muaj rau ua tau ABO genotypes tab sis tsuas yog plaub phenotypes.
Ua raws li qhov no hauv kev txiav txim siab, pes tsawg tus phenotypes tsim rau qhov zoo muaj feem cuam tshuam nrog cov noob cuam tshuam rau nws?
Lub genome uas pom muaj genotype tuaj yeem pom cuam tshuam kev nthuav qhia ntawm genotype, thiab ib puag ncig tuaj yeem cuam tshuam tus phenotype . Cov noob tuaj yeem ua pleitropic thaum lawv cuam tshuam ntau tshaj ib qhov zoo . Ib qho kev hloov pauv hauv ib qho uas ua rau mob qog ntshav ntshav yog ib qho piv txwv classic.
Koj txiav txim siab li cas phenotype?
Lub sij hawm " phenotype "yog hais txog cov yam ntxwv ntawm lub cev uas pom tau ntawm lub cev; cov no suav nrog lub cev zoo li, kev loj hlob, thiab tus cwj pwm. phenotype yog txiav txim siab los ntawm nws cov genotype, uas yog cov txheej txheem ntawm cov noob kab mob, nrog rau los ntawm ib puag ncig cuam tshuam rau cov noob no.

Yuav ua li cas koj nrhiav tau tus naj npawb ntawm electrons nyob rau hauv ib tug uncharged atom?
Tus naj npawb atomic sawv cev rau tus naj npawb ntawm protons hauv atom lub nucleus. Hauv ib qho atom uas tsis tau them nyiaj, tus naj npawb ntawm cov protons ib txwm sib npaug ntawm cov electrons. Piv txwv li, carbon atoms suav nrog rau protons thiab rau electrons, yog li cov pa roj carbon monoxide yog 6
Yuav ua li cas koj nrhiav tau tus naj npawb ntawm covalent bonds nyob rau hauv ib tug compound?
Tus naj npawb ntawm daim ntawv cog lus rau ib qho atom nruab nrab yog sib npaug rau cov xov tooj ntawm cov hluav taws xob hauv lub plhaub valence tag nrho (2 los yog 8 electrons) rho tawm cov valence electrons. Txoj kev no ua haujlwm vim tias txhua daim ntawv cog lus sib cog lus uas ib qho atom tsim ntxiv lwm lub tshuab hluav taws xob rau lub atoms valence plhaub yam tsis hloov nws cov nqi

Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
