Peb kub cov xov hlau hauv ib peb - theem Circuit Court yog xim dub, xiav thiab liab; ib dawb hlau yog qhov nruab nrab thiab ntsuab hlau yog siv rau hauv av.
Tsis tas li ntawd, koj yuav ua li cas paub yog tias nws ib theem lossis peb theem?
Lwm tus txoj kev txheeb xyuas peb theem los ntawm ib theem yog qhov dav ntawm lub ntsiab hloov. Ib theem keyboards yog 'ib tug ncej' dav, whereas 3 faaj keyboards yog ' peb ncej 'dav.
Qhov thib ob, pes tsawg volts yog 3 theem? Qhov voltage ntawm ob kab yog hu ua kab voltage. 3 faaj system yog qhia nrog kab voltages. Qhov kev pab cuam yog 440 hluav taws xob . Kuj qhov voltage ntawm ib qho twg theem thiab nruab nrab rau ib 3 faaj Qhov system yog 240 hluav taws xob.
Ntawm no, dab tsi yog xim code rau 3 theem thaiv?
Theem 3 - Xiav. Nruab nrab - Dawb. Av - Ntsuab nrog daj kab txaij.
Ib theem twg tuaj yeem hloov mus rau peb theem?
Kev hloov pauv theem yog tus txheej txheem ntawm converting ib theem zog in 3 faaj zog. A " theem converter" tsim ib tug thib peb kab ntawm voltage (ib tug thib peb sine yoj) cia peb theem lub zog yuav ua tau nyob rau hauv ib ib theem ib puag ncig.

Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
Cov roj twg coj zoo tshaj plaws zoo li cov pa roj zoo?
helium Raws li txoj cai, koj ua li cas txiav txim siab seb cov roj twg coj zoo tshaj plaws? Feem ntau, a gas coj mas zoo li ib zoo tagnrho gas ntawm qhov kub siab dua thiab qis dua, vim tias lub zog muaj peev xwm vim muaj zog intermolecular ua tsawg dua piv nrog cov khoom 'kinetic zog, thiab qhov loj ntawm cov molecules yuav tsawg dua piv rau qhov khoob ntawm lawv.
