Bioaccuulation yog qhov tsuj zuj zus ntawm cov tshuaj, xws li tshuaj tua kab lossis lwm yam tshuaj, hauv lub cev. Bioaccuulation tshwm sim thaum lub cev absorbs ib yam khoom ntawm tus nqi sai tshaj qhov uas cov khoom ploj los ntawm catabolism thiab excretion.
Tom qab ntawd, qee qhov piv txwv ntawm bioaccumululation yog dab tsi?
Piv txwv ntawm bioaccumululation thiab biomagnification muaj xws li:
- Lub tsheb emission tshuaj tsim nyob rau hauv cov noog thiab lwm yam tsiaj.
- Mercury tsim nyob rau hauv cov ntses.
- Cov tshuaj tua kab tsim hauv cov tsiaj me.
Ib sab saum toj, vim li cas bioaccumululation tsis zoo? Bioaccuulation tshwm sim thaum co toxins tsim - lossis sib sau - hauv cov khoom noj khoom haus. Cov tsiaj nyob rau sab saum toj ntawm cov saw zaub mov raug cuam tshuam loj tshaj plaws. Qhov no tshwm sim: Cov tshuaj lom me me - feem ntau yog tshuaj tua kab lossis kev ua qias tuaj ntawm tib neeg kev ua - yog nqus los ntawm cov nroj tsuag.
Ib yam li ib tug yuav nug, dab tsi yog biomagnification hauv biology?
Biomagnification , tseem hu ua bioamplification los yog lom magnification, yog ib qho concentration ntawm cov tshuaj lom, xws li tshuaj tua kab, nyob rau hauv cov ntaub so ntswg ntawm cov kab mob uas kam rau ua nyob rau hauv successively siab nyob rau hauv ib tug noj mov saw.
Biomagnification yog dab tsi thiab nws tshwm sim li cas?
Biomagnification txheej txheem tshwm sim Thaum qee cov tshuaj lom thiab cov kuab paug xws li cov hlau hnyav, tshuaj tua kab lossis polychlorinated biphenyls (PCBs) cov khoom sib txuas nce mus rau cov khoom noj khoom haus los ntawm kev ua haujlwm ntawm ib puag ncig thiab mus rau hauv av lossis hauv dej tom qab ntawd lawv noj los ntawm cov tsiaj hauv dej los yog cov nroj tsuag,

Dab tsi yog qhov txhais ntawm lub hauv paus hauv biology?
Txhais. npe, plural: bases. (1) (molecular biology) Lub nucleobase ntawm nucleotide koom nrog hauv kev sib koom ua ke, xws li DNA lossis RNA polymer. (2) (anatomy) Qhov qis tshaj plaws los yog hauv qab ntawm cov nroj tsuag lossis tsiaj lub cev ze tshaj rau qhov txuas. (3) (chemistry) Ib qho dej-soluble compound uas reacts nrog acid thiab cov ntaub ntawv
Dab tsi yog qeb yog marine biology nyob rau hauv?
Marine biology yog ib ceg ntawm biology. Nws muaj kev sib raug zoo nrog oceanography thiab tej zaum yuav raug suav hais tias yog ib qho kev ua haujlwm ntawm kev tshawb fawb hauv dej hiav txwv. Nws tseem suav nrog ntau lub tswv yim los ntawm ecology. Kev tshawb fawb txog kev nuv ntses thiab kev txuag dej hiav txwv tuaj yeem suav hais tias yog ib feem ntawm kev ua liaj ua teb marine biology (nrog rau kev tshawb fawb ib puag ncig)
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
Dab tsi yog bioaccumulation muab piv txwv?
Bioaccumulation yog tsim cov tshuaj nyob rau hauv cov kab mob. Piv txwv ntawm bioaccumululation thiab biomagnification muaj xws li: Tsheb emission tshuaj tsim nyob rau hauv cov noog thiab lwm yam tsiaj. Mercury tsim nyob rau hauv cov ntses
Puas yog General Biology tib yam li cov hauv paus ntsiab lus ntawm biology?
Ob qho! Kuv xav tias nws nyob ntawm koj lub tsev kawm ntawv. Hauv kuv lub tsev kawm ntawv, cov ntsiab cai ntawm bio yog npaj rau bio majors, qhov dav dav bio yog rau lwm yam loj uas xav tau biology, uas yuav yooj yim dua
