Mendel pom tias muaj lwm hom ntawv yam - tam sim no hu genes - uas tus account rau variations nyob rau hauv cov yam ntxwv qub txeeg qub teg. Piv txwv li, cov noob rau paj xim nyob rau hauv peas nroj tsuag muaj nyob rau hauv ob daim ntawv, ib tug rau ntshav thiab lwm yam rau dawb. Lwm qhov "forms" yog tam sim no hu alleles.
Tib neeg kuj nug, dab tsi yog Mendelian yam?
Mendelian yam tsuas yog cov noob caj noob ces. Mendel thaum ua qhov kev sim ntawm qhov qub txeeg qub teg (dhau ntawm ib tiam mus rau lwm tus) ntawm qhov zoo (cov yam ntxwv), siv lub sij hawm yam rau cov units uas code rau cov yam ntxwv no. Tom qab ntawd, cov no yam tau muab lub sij hawm genes.
Ib yam li ntawd, txoj kev tshawb fawb txog keeb kwm yog hu ua dab tsi? Hnub no, thaum cov kws tshawb fawb tham txog caj ces , lawv tham txog cov noob caj noob ces. Qhov no yog vim li cas lub kev kawm txog kev yug los yog hu ua "genetics."
Kuj Paub, Mendel's 3 Laws yog dab tsi?
Mendel cov kev kawm tau txais txiaj ntsig peb " kev cai " ntawm qub txeeg qub teg: lub txoj cai ntawm dominance, lub txoj cai ntawm segregation, thiab txoj cai ntawm kev ywj pheej assortment. Txhua yam ntawm no tuaj yeem nkag siab los ntawm kev tshuaj xyuas cov txheej txheem ntawm meiosis.
Puas yog txoj kev tshawb fawb txog kev yug me nyuam hu ua fertilization?
TRUE OR FALSE: Tus scientific kev tshawb fawb ntawm heredity yog hu ua FERTILIZATION . QHOV TSEEB LOS YOG FALSE: Ib hom kab mob HYBRID yog cov xeeb ntxwv ntawm ntau tiam neeg uas muaj tib daim ntawv ntawm qhov zoo.

Yuav ua li cas hloov DC tam sim no rau AC tam sim no?
Lub hwj chim inverter, los yog inverter, yog apowerelectronic ntaus ntawv los yog circuitry uas hloov directcurrent (DC) mus rau alternating tam sim no (AC).Inputvoltage, tso zis voltage thiab zaus, thiab overallpower tuav nyob ntawm tus tsim ntawm lub specificdeviceor circuitry
Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Dab tsi yog qhov kev ua yuam kev hauv kev sim nrog cov hluav taws xob tam sim no?
Cov peev txheej ntawm kev ua yuam kev suav nrog cov cuab yeej, ib puag ncig, txheej txheem, thiab tib neeg. Tag nrho cov kev ua yuam kev no tuaj yeem ua tsis tau lossis ua haujlwm nyob ntawm seb lawv cuam tshuam li cas. Instrumental yuam kev tshwm sim thaum cov cuab yeej siv tsis raug, xws li qhov sib npaug uas tsis ua haujlwm (SF Fig
Dab tsi yog ntau yam xwm txheej uas tau khaws cia zoo ib yam hauv kev sim?
Ib qho kev sib txawv yog txhua yam, qhov zoo, lossis qhov xwm txheej uas tuaj yeem muaj nyob hauv ntau qhov sib txawv lossis hom. Ib qho kev sim feem ntau muaj peb hom kev hloov pauv: ywj siab, nyob ruaj khov, thiab tswj tau. Qhov kev hloov pauv ywj pheej yog qhov hloov pauv los ntawm tus kws tshawb fawb
