Minuend . Thawj tus lej hauv a rho tawm . Tus lej los ntawm lwm tus lej (lub Subtrahend) yuav tsum yog rho tawm . Piv txwv li: hauv 8 − 3 = 5, 8 yog tus tsawg kawg.
Ntawm no, lo lus teb rau qhov teeb meem rho tawm yog dab tsi?
Thawj tus nqi yog qhov minuend. Qhov thib ob tus nqi (tus koj yog rho tawm ) hu ua subtrahend. Cov teb hauv a teeb meem rho tawm hu ua qhov txawv. Qhov tseeb, tej zaum koj yuav tsum nco ntsoov tias qhov teb rau qhov teeb meem rho tawm hu ua qhov txawv.
Tsis tas li ntawd, hu ua Subtrahend? Tus lej uas yuav tsum tau muab rho tawm. Tus lej thib ob hauv kev rho tawm. tsawg kawg − subtrahend = txawv. Piv txwv li: hauv 8 - 3 = 5, 3 yog qhov subtrahend.
Ib yam li ntawd ib tug yuav nug, dab tsi yog cov ntsiab lus ntawm qhov teeb meem rho tawm?
Peb ntu ntawm tej teeb meem rho tawm yog qhov minuend, qhov koj pib nrog; lub subtrahend, ib feem raug muab tshem tawm; thiab qhov sib txawv, qhov seem tshuav.
Cov lus teb rau qhov teeb meem ntxiv yog dab tsi?
Ob qhov tseem ceeb hauv ib qho teeb meem ntxiv hu ua "ntxiv" thiab cov teb hu ua "sum." Koj tseem yuav pom ob qhov sib txawv layouts ntawm teeb meem ntxiv.

Dab tsi yog qhov txawv ntawm qhov teeb meem thiab lub zog hauv ib qho ecosystem?
Muaj qhov sib txawv tseem ceeb hauv txoj kev lub zog thiab cov teeb meem ntws los ntawm ib qho ecosystem. Cov teeb meem ntws los ntawm ecosystem nyob rau hauv daim ntawv ntawm cov tsis muaj sia nyob cov as-ham tseem ceeb rau cov kab mob nyob. Yog li koj pom, teeb meem yog rov ua dua tshiab hauv ecosystem. Tsis zoo li qhov teeb meem, lub zog tsis rov siv dua los ntawm qhov system
Dab tsi yog qhov txawv ntawm qhov ntws ntawm cov teeb meem thiab lub zog hauv ib qho ecosystem?
Muaj qhov sib txawv tseem ceeb hauv txoj kev lub zog thiab cov teeb meem ntws los ntawm ib qho ecosystem. Cov teeb meem ntws los ntawm ecosystem hauv daim ntawv ntawm cov khoom noj uas tsis muaj sia nyob uas tseem ceeb rau cov kab mob nyob. Yog li koj pom, teeb meem yog rov siv dua hauv ecosystem. Tsis zoo li qhov teeb meem, lub zog tsis rov siv dua los ntawm qhov system
Dab tsi yog qhov teeb meem ntawm lub teeb nyob rau hauv lub ntuj hmo ntuj hu ua?
Gegenschein, tseem hu ua Counterglow, oval thaj ntawm faint luminosity raws nraim rau lub hnub nyob rau hauv lub hmo ntuj. Lub thaj ntawm lub teeb yog li faint nws tuaj yeem pom tsuas yog thaum tsis muaj lub hli, nyob deb ntawm lub nroog teeb, thiab nrog lub qhov muag yoog rau qhov tsaus ntuj
Yuav ua li cas rho tawm rho tawm haujlwm?
Rho dependent termination yog ib qho ntawm ob hom kev txiav tawm hauv prokaryotic transcription, lwm qhov yog intrinsic (los yog Rho-independent). Tom qab khi rau cov saw tshiab RNA, ρ qhov tseem ceeb txav mus raws cov molecule hauv 5'-3' kev taw qhia thiab txhawb kev sib cais los ntawm DNA qauv thiab RNA polymerase
Dab tsi yog qhov kev faib tawm ntawm cov teeb meem raws li muaj pes tsawg leeg?
Cov teeb meem tuaj yeem muab faib ua ob pawg dav: cov tshuaj ntshiab thiab cov khoom sib tov. Cov khoom ntshiab yog ib daim ntawv ntawm cov teeb meem uas muaj qhov sib xyaw ua ke thiab cov khoom uas tsis tu ncua thoob plaws hauv cov qauv. Kev sib xyaw ua ke yog kev sib xyaw ua ke ntawm ob lossis ntau lub ntsiab lus thiab / lossis cov khoom sib txuas
