Bioconcentration yog qhov tshwj xeeb bioaccuulation txheej txheem los ntawm cov concentration ntawm ib tug tshuaj nyob rau hauv ib tug kab mob yuav siab tshaj nws concentration nyob rau hauv cov huab cua los yog dej nyob ib ncig ntawm lub cev. Hmoov zoo, bioaccumulation ua tsis yog ib txwm ua rau biomagnification.
Xav txog qhov no, biomagnification puas tuaj yeem tsis muaj bioaccumulation?
Ib qho txawv yog qhov ntawd bioaccuulation hais txog kev tsim cov tshuaj nyob rau hauv lub cev ntawm ib lub cev thaum biomagnification hais txog kev txhim kho hauv ntau lub cev. Biomagnification kuj yuav tsum tau txav mus rau cov khoom noj khoom haus kom tshwm sim, thaum bioaccuulation tsis xav kom tus tsiaj noj.
Ib sab saum toj no, dab tsi yog qhov ua rau biomagnification lossis bioaccumululation? Cov vim li cas yog vim li cas koj thiaj li yuav tsum txwv kom tsawg npaum li cas ntses koj noj yog vim noj ntses, tshwj xeeb tshaj yog nyob rau hauv loj npaum li cas, uas twb tau sau mercury nyob rau hauv biomagnification hauv koj lub cev. Biomagnification yog hom bioaccuulation qhov twg tus nqi ntawm ib tug tshuaj multiplies txhua txhua lub sij hawm nws txav mus rau cov khoom noj khoom haus saw.
Hais txog qhov no, puas yog bioaccumululation tib yam li biomagnification?
Bioaccuulation hais txog kev sib sau ntawm cov tshuaj lom neeg hauv cov ntaub so ntswg ntawm ib yam kabmob. Biomagnification hais txog qhov nce ntxiv ntawm cov tshuaj lom neeg ntau dua tus tsiaj nyob rau ntawm cov khoom noj.
Qib twg ntawm cov khoom noj khoom haus feem ntau cuam tshuam los ntawm biomagnification?
Feem ntau, cov tsiaj nyob ze rau saum lub saw khoom noj yog feem ntau cuam tshuam vim txoj kev hu ua biomagnification . Ntau yam ntawm feem ntau cov co toxins txaus ntshai nyob rau hauv qab dej hiav txwv thiab tom qab ntawd raug coj los ntawm cov kab mob uas nyob los yog pub rau hauv qab cov sediments.

Thaum lawv ntsuas qhov nrug ntawm cov ntsiab lus, dilations tsis hloov lub kaum sab xis. Kev hloov pauv cuam tshuam rau txhua lub ntsiab lus hauv lub dav hlau, tsis yog cov duab tshwj xeeb uas peb xaiv los txheeb xyuas thaum ua haujlwm nrog kev hloov pauv. Txhua qhov ntev ntawm kab ntu hauv lub dav hlau yog ntsuas los ntawm tib yam thaum peb siv dilation
Puas yog cov lej ib txwm muaj qee zaum lossis tsis muaj tus lej sib piv?
1.5 yog tus lej rational uas tuaj yeem sau tau li: 3/2 qhov twg 3 thiab 2 ob leeg yog tus lej. Ntawm no tus lej rational 8 yog tus lej, tab sis tus lej rational 1.5 tsis yog tus lej li 1.5 tsis yog tus lej tag nrho. Yog li peb tuaj yeem hais tias Tus lej rational yog ib qho integer qee zaum tsis tas li. Yog li ntawd, tej zaum lo lus teb raug yog
Puas yog theem hloov pauv ib txwm hloov lub cev?
Teeb meem ib txwm hloov daim ntawv, qhov loj me, cov duab, xim, thiab lwm yam. Muaj 2 hom kev hloov pauv uas tseem ceeb dhau mus. Phase Changes yog PHYSICAL PHYSICAL!!!!! TAG NRHO cov theem kev hloov pauv yog tshwm sim los ntawm kev ntxiv lossis tshem tawm lub zog
Puas yog tetrahedron Ib txwm polyhedron?
Lub tetrahedron yog polyhedron nrog 4 daim duab peb sab raws li nws lub ntsej muag. Cov polyhedra tsis tu ncua yog ib yam nkaus thiab muaj ntsej muag ntawm txhua yam ntawm ib hom kev sib koom ua ke tsis tu ncua. Muaj tsib yam tsis tu ncua polyhedra. Lub polyhedra tsis tu ncua yog ib feem tseem ceeb ntawm Plato lub ntuj lub tswv yim, thiab yog li tau los hu ua Platonic Solids
Dab tsi yog qhov ua rau biomagnification lossis bioaccumulation?
Cov txheej txheem biomagnification tshwm sim thaum qee yam tshuaj lom thiab cov kuab paug xws li cov hlau hnyav, tshuaj tua kab lossis cov tshuaj polychlorinated biphenyls (PCBs) nce mus rau cov khoom noj los ntawm kev ua haujlwm los ntawm ib puag ncig thiab mus rau hauv av lossis hauv dej tom qab uas lawv tau noj los ntawm cov tsiaj hauv dej. los yog nroj tsuag
