Hybridization yog tus txheej txheem ntawm kev hla kev sib txawv ntawm cov tib neeg los tsim cov xeeb ntxwv, whereas kev yug me nyuam yog kev hla ntawm ob tug niam txiv uas nyob ze (cov txheeb ze ze) uas sib koom heev zoo sib xws alleles. Kev yug me nyuam koom nrog tag nrho cov tsiaj nyob, whereas hybridization suav nrog ib feem ntawm cov tsiaj lossis cov nroj tsuag.
Ib yam li ntawd, ib tug yuav nug, yuav ua li cas xaiv kev yug me nyuam ntawm hybridization thiab inbreeding opposites?
Hybridization thiab inbreeding yog tawm tsam ntawm spectrum ntawm kev sib txawv ntawm caj ces. Hybridization tsim cov xeeb ntxwv uas txawv heev los ntawm leej niam leej txiv caj ces thiab yuav heterozygous heev (cov alleles los ntawm txhua tus niam txiv zoo li yuav txawv heev).
Ib sab saum toj no, cov kab mob transgenic tau pab tau li cas? Cov kab mob hloov caj ces yog thawj cov kab mob uas tau hloov kho hauv chav kuaj, vim lawv cov caj ces yooj yim. Cov kab mob no tam sim no tau siv rau ntau lub hom phiaj, thiab tseem ceeb tshwj xeeb hauv kev tsim cov protein ntau ntshiab tib neeg rau kev siv tshuaj.
Tsis tas li lo lus nug yog, ua li cas cov neeg yug tsiaj tsim cov noob caj noob ces uas tsis pom nyob hauv qhov xwm txheej?
Los ntawm inducing mutations nrog tshuaj los yog hluav taws xob. Piav vim li cas caj ces engineering tuaj yeem muab piv rau reprogramming lub computer game. Ob leeg muaj cov lej uas tuaj yeem raug cais tawm thiab hloov pauv hloov cov yam ntxwv ntawm kev ua si lossis lub cev.
Qhov twg yog ib qho piv txwv ntawm kev xaiv yug me nyuam?
Tshiab ntau yam txawv ntau yam ntawm nroj tsuag thiab cov tsiaj uas xav tau yam ntxwv tuaj yeem tsim los ntawm kev xaiv yug me nyuam. Piv txwv li: nyuj uas tsim mis nyuj ntau. qaib uas tsim qe loj.

Yuav ua li cas yog Oceanic Oceanic thiab Oceanic Continental convergent ciam teb zoo sib xws?
Lawv yog ob qho tib si convergent zones, tab sis thaum lub phaj dej hiav txwv converges nrog continental phaj, dej hiav txwv phaj yog yuam kom nyob rau hauv lub continental phaj vim dej hiav txwv crust yog thinner thiab denser tshaj continental crust
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm qhov nrawm thiab nrawm?
Kev sib piv daim duab piv rau Kev Sib Piv Ceev Ceev Tus Nqi Hloov ntawm qhov kev ncua deb Hloov pauv hloov thaum lub cev rov qab mus rau nws qhov chaw pib Yuav tsis xoom Yuav yog xoom Tsiv khoom Ceev ntawm cov khoom txav tsis tuaj yeem tsis zoo. Kev nrawm ntawm cov khoom txav tuaj yeem yog qhov zoo, tsis zoo lossis xoom
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Puas yog ob txoj kab sib luag zoo sib xws lossis tsis sib xws?
Yog tias ob qhov sib npaug piav txog kab sib luag, thiab yog li cov kab uas tsis sib tshuam, qhov system yog ywj siab thiab tsis sib haum. Yog hais tias ob qhov sib npaug piav txog tib kab, thiab yog li cov kab uas hla tus lej tsis kawg, lub kaw lus yog nyob ntawm thiab sib xws
Koj tuaj yeem ua pov thawj li cas 2 daim duab peb sab zoo sib xws siv lub kaum sab xis sab SAS zoo sib xws postulate?
SAS Similarity Theorem hais tias yog ob sab hauv ib daim duab peb sab yog proportional rau ob sab hauv lwm daim duab peb sab thiab lub kaum sab xis nyob rau hauv ob qho tib si congruent, ces ob daim duab peb sab zoo ib yam. Ib qho kev hloov pauv zoo sib xws yog ib lossis ntau qhov kev hloov pauv tsis tu ncua ua raws li kev dilation
