Nyob rau hauv txhua ntawm peb lub teb chaws, peb nrhiav tau lub nceeg vaj, cov thib ob qeb nyob rau hauv kev faib taxonomic, ua raws li cov pawg tom ntej uas suav nrog phylum ua , chav kawm kev, tsev neeg, genus , thiab hom . Nyob rau hauv txhua chav kawm, cov kab mob ua kom zoo sib xws vim lawv muaj kev sib raug zoo dua.
Nyob rau hauv txoj kev no, dab tsi yog ib pab pawg neeg muaj feem xyuam nrog hu ua?
npe group ntawm cov kab mob. genus. taxonomic pab pawg neeg uas muaj kev sib raug zoo nrog ib tug poj koob yawm txwv.family. taxonomic pab pawg ntawm zoo sib xws, ntsig txog generathat yog me dua ib lub genus thiab loj tshaj qhov kev txiav txim.
Tom qab ntawd, lo lus nug yog, ob tug tsiaj twg yog hma feem ntau cuam tshuam nrog? Canis lupus yog tus hma . Canis familiaris yog cov dog dig. Sau tag nrho cov se uas cov no ob hom muaj kev sib koom. Qhov twg ob kab mob yog sib ze tshaj plaws ?
Ib yam li ntawd, nws raug nug, cov tsiaj hauv tib tsev neeg puas muaj feem cuam tshuam ntau dua li cov tsiaj hauv tib chav?
Hom uas yog nyob rau hauv tib tsev neeg yog muaj kev sib raug zoo ntau dua li cov tsiaj hauv tib chav kawm . Justremember Kingdom, Phem, Chav kawm , Order, Tsev neeg , Genus, Hom . Qhov ntxiv down koj tau txais nyob rau hauv lub taxa, lub zoo sib xws tus hom yog ib leeg.
Dab tsi yog pawg siab dua hauv kev faib tawm niaj hnub no?
Lub Taxonomic Kev faib tawm Qhov System niaj hnub taxonomic kev faib tawm system muaj yim theem tseem ceeb (los ntawm feem ntau suav nrog rau feem ntau tshwj xeeb): Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species Identifier.

Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Cov kab mob twg muaj cov kab mob eukaryotic?
Cov kab mob thiab Archaea tsuas yog prokaryotes. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes. Tsiaj txhu, nroj tsuag, fungi, thiab protists yog eukaryotes. Tag nrho cov kab mob multicellular yog eukaryotes
Vim li cas cov kab mob feem ntau tsim cov xeeb ntxwv ntau dua li muaj sia nyob?
Cov kab mob tsim cov xeeb ntxwv ntau dua li qhov muaj sia nyob. Cov kab mob tuaj yeem tuag los ntawm ntau yam ua rau: kab mob, kev tshaib plab, thiab noj, thiab lwm yam. Ib puag ncig tsis tuaj yeem txhawb nqa txhua yam kabmob uas yug los. Ntau tus tuag ua ntej lawv muaj peev xwm rov tsim dua
Hom molecules twg feem ntau yog siv los ntawm cov kab mob rau quorum sensing?
Cov kab mob Gram-negative thiab Gram-positive siv hom kev sib txuas lus no, txawm hais tias cov teeb liab molecules (auto-inducers) siv los ntawm lawv txawv ntawm ob pawg: Gram-negative bacteria siv feem ntau N-acyl homoserine lacton (AHL) molecules (autoinducer- 1, AI-1) thaum cov kab mob Gram-zoo siv feem ntau peptides (
Qhov twg ntawm cov ntsiab lus hauv qab no feem ntau pom nyob rau hauv feem ntau cov chiv?
Cov tshuaj chiv niaj hnub suav nrog ib lossis ntau tshaj ntawm peb lub ntsiab lus tseem ceeb tshaj plaws hauv cov zaub mov noj: nitrogen, phosphorus, thiab potassium. Qhov tseem ceeb thib ob yog cov ntsiab lus sulfur, magnesium, thiab calcium
