Yog hais tias lub cev muaj ob daim ntawv luam ntawm tib allele, rau piv txwv AA or aa, yog homozygous rau qhov zoo. Yog hais tias lub cev muaj ib daim qauv ntawm ob qho sib txawv alleles, rau piv txwv Aa, nws yog heterozygous.
Hauv qhov no, qhov piv txwv ntawm heterozygous yog dab tsi?
Heterozygous txhais tau hais tias lub cev muaj ob qhov sib txawv ntawm cov noob. Rau piv txwv , pea nroj tsuag canhav liab paj thiab yog homozygous dominant (liab-liab), los yog heterozygous (liab-dawb). Yog hais tias lawv muaj paj dawb, ces lawv yog homozygous recessive (dawb-dawb). Cov neeg nqa khoom ib txwm muaj heterozygous.
Ib tug kuj yuav nug, homozygous mob yog dab tsi? Homozygous yog caj ces mob qhov twg ib tus neeg txais tau tib lub alleles rau ib qho gene los ntawm ob leeg niam txiv.
Ib yam li ntawd, koj tuaj yeem nug, qhov piv txwv ntawm homozygous recessive yog dab tsi?
Piv txwv ntawm Homozygous Recessive Gene Cov noob albinism nyob ntawm qee qhov chaw, lossis tso rau ntawm DNA strand. Muaj ob hom ntawm cov noob, hu ua alleles.
Ua li cas koj thiaj paub tias nws homozygous lossis heterozygous?
Genotypes, tsis zoo li phenotypes, tuaj yeem ua tau homozygous los yog heterozygous . Yog lub cev yog heterozygous rau ib lub noob, lossis muaj ib qho ntawm txhua tus allele, ces qhov tseem ceeb tshaj plaws yog qhia. Ib qho allele recessive tsuas yog qhia yog lub cev yog homozygous rau qhov zoo li ntawd, los yog muaj ob lub recessive alleles.

Ib qho piv txwv ntawm ib qho alloy yog dab tsi?
Ib qho piv txwv ntawm cov hlau yog sib xyaw ntawm cov hlau thiab hlau. Ib qho piv txwv ntawm cov hlau yog cov tin hauv qhov sib xyaw ntawm tooj liab thiab tin uas ua rau tooj liab. Lub alloy yog ib qho fusion ntawm ob lossis ntau dua hlau lossis cov hlau uas tsis yog hlau. Ib qho piv txwv ntawm cov hlau yog tooj dag, uas yog tsim los ntawm tooj liab thiab zinc
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
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 txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
