Vim li cas nws thiaj zoo rau cov kws tshawb fawb siv lub npe los ntawm cov txheej txheem taxonomic ? Cov standardized npe differentiates roob tsov ntxhuav thiab pumas. Lub Linnaean taxonomic system cais cov kab mob mus rau hauv kev faib hu ua taxa. Yog tias ob lub cev muaj tib yam taxonomic pab pawg, lawv muaj feem cuam tshuam.
Cov lus nug tseem yog, dab tsi yog taxonomy nws muaj txiaj ntsig zoo li cas?
system naturae yog ib hom phau ntawv sau los ntawm Carl Linnaeus txog taxonomy. taxonomy yog ib ceg ntawm kev tshawb fawb uas cuam tshuam nrog kev faib cov kab mob. Nws yog ib qho tseem ceeb vim hais tias nws pab peb systmatise stydy ntawm cov kab mob nyob.
Ib tug kuj nug, leej twg yog leej txiv ntawm taxonomy? Carolus Linnaeus
Ua raws li qhov no, vim li cas cov kws tshawb fawb siv cov npe Latin es tsis txhob siv cov npe?
Cov npe scientific yog siv los piav txog ntau hom kab mob nyob rau hauv ib txoj kev uas yog universal li ntawd cov kws tshawb fawb nyob ib ncig ntawm lub ntiaj teb no tuaj yeem txheeb xyuas tib yam tsiaj. Qhov no yog hu ua binomial nomenclature, thiab ntau ntawm cov npe scientific tau los ntawm Latin npe ntawm lub cev.
Lub hom phiaj tseem ceeb ntawm taxonomy yog dab tsi?
Taxonomy aims thaum ua tiav peb lub hom phiaj tseem ceeb : 1. Ua ntej, taxonomy aims ntawm kev faib cov kab mob mus rau hauv taxa raws li qhov zoo sib xws hauv phenotypic (phenetic) cov yam ntxwv piv txwv li cov yam ntxwv uas tau hais hauv kab mob thiab tuaj yeem kuaj pom qhov muag lossis tuaj yeem kuaj los ntawm lwm txoj kev.

Inventor: Dmitri Mendeleev
Vim li cas nws yog ib lub tswv yim zoo los cawm tag nrho cov txheej txheem ntawm koj cov extraction kom txog thaum kawg ntawm kev sim?
Kev ua yuam kev thaum lub sijhawm rho tawm (piv txwv li nqa nrog cov txheej txheem tsis raug), tuaj yeem daws tau yog tias cov kev daws tsis tau muab tso rau hauv lub thawv pov tseg! Cov khaubncaws sab nraud povtseg yuav tsum tau txais kev cawmdim kom txog thaum tom qab evaporation vim hais tias cov khoom xav tau yuav tsis soluble heev hauv cov kuab tshuaj siv
Tib neeg ua ntej hloov cov qoob loo li cas cov kws tshawb fawb siv niaj hnub no los hloov cov qoob loo?
Los ntawm cucumbers thiab carrots rau dawb nplej thiab nplej, peb tib neeg tau hloov cov noob ntawm yuav luag txhua yam zaub mov peb noj. Niaj hnub no cov kws tshawb fawb tuaj yeem tsim qhov kev hloov pauv sai sai los ntawm kev xaiv ib lub noob uas yuav ua rau muaj qhov xav tau thiab tso cov noob ncaj qha mus rau hauv chromosome ntawm lub cev
Cov txheej txheem dab tsi uas tus kws tshawb fawb siv los tsim ntau cov ntawv luam ntawm DNA xav tau sau rau hauv daim ntawv dawb paug 1?
Molecular Cloning. Cloning tso cai rau tsim ntau cov ntawv luam ntawm cov noob, qhia cov noob, thiab kawm txog cov noob tshwj xeeb. Yuav kom tau txais cov DNA tawg rau hauv cov kab mob hauv cov kab mob hauv daim ntawv uas yuav tau theej lossis nthuav tawm, cov khoom tawg yog thawj zaug tso rau hauv plasmid
