Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog tus nab npawb khawv koob nyob rau hauv cov nqe lus ntawm lub sij hawm luv luv thiab qhov no txhais li cas?
Capacity of Short-Term Memory Yuav ua li cas yog tus lej tej yam yees siv nyob rau hauv cov nqe lus ntawm lub sij hawm luv luv nco (STM)? Nws txhais tau hais tias tus naj npawb tiag tiag ntawm cov khoom uas tus neeg laus tuaj yeem tuav tau hauv STM yog los ntawm 5 txog 9, rau cov neeg feem coob thiab feem ntau cov dej num, txhua yam ua tsis tau tom qab txog 7 yam khoom tsis cuam tshuam, ces cov khoom yuav poob los yog tso tawm
Nws txhais li cas los sau koj cov lus teb nyob rau hauv cov nqe lus ntawm pi?
Cov lus teb meej txhais tau tias koj tsis xav tau lub tshuab xam zauv, tsuas yog tso koj cov lus teb kawg uas qhia txog Pi. Lub voj voog ntawm lub voj voog tuaj yeem pom siv cov qauv C = Pid. C yog qhov ncig (qhov perimeter) thiab d yog txoj kab uas hla. Yog li hauv paus koj tsuas yog yuav tsum tau muab txoj kab uas hla los ntawm Pi
Dab tsi ua rau lub tsev cog khoom piav qhia nyob rau hauv cov nqe lus ntawm hluav taws xob wavelengths?
Greenhouse Effect. Cov nyhuv tsev cog khoom hais txog qhov xwm txheej uas qhov luv wavelengths ntawm pom lub teeb los ntawm lub hnub dhau los ntawm qhov nruab nrab pob tshab thiab tau nqus, tab sis qhov ntev wavelengths ntawm infrared re-radiation los ntawm cov khoom rhuab tsis tuaj yeem dhau los ntawm qhov nruab nrab
Kev qoj ib ce txhais li cas hauv cov ntsiab lus evolutionary?
Biologists siv lo lus kev noj qab haus huv los piav txog qhov zoo ntawm ib qho genotype zoo li cas ntawm cov xeeb ntxwv nyob rau tiam tom ntej txheeb ze rau qhov zoo ntawm lwm cov genotypes ntawm nws. Lub genotype lub cev muaj xws li nws lub peev xwm kom muaj sia nyob, nrhiav tus khub, tsim cov xeeb ntxwv - thiab thaum kawg tso nws cov noob rau tiam tom ntej
