Kev hloov caj ces yog hu ua kev hloov pauv thiab tus neeg sawv cev ua rau kev hloov pauv raws li mutagen. Genotoxicity zoo ib yam li mutagenicity tshwj tsis yog tias cov teebmeem genotoxic tsis tas yuav cuam tshuam nrog kev hloov pauv. Tag nrho cov mutagens yog genotoxic, txawm li cas los xij, tsis yog txhua yam tshuaj genotoxic yog mutagenic.
Dab tsi yog genotoxicity thiab mutagenicity?
Genotoxicity yog lub xeev ua rau muaj tshuaj lom rau ntawm genome(DNA + CHROMOSOMES) tab sis mutagenicity yog concentrated nyob ib ncig ntawm DNA.
Yam tshuaj genotoxicity yog dab tsi?
Kev kuaj Genotoxicity tuaj yeem txhais tau raws li hauv vitro thiab hauv vivo cov kev sim tsim los xyuas cov tebchaw uas ua rau muaj kev puas tsuaj los ntawm ntau yam txheej txheem. Cov kev ntsuam xyuas no ua rau muaj kev phom sij txog kev puas tsuaj rau DNA thiab nws txoj kev kho.
txhais li cas los ntawm genotoxicity?
Cov lus zoo ib yam: genotoxicity. Lus Txhais: Toxic (kev puas tsuaj) rau DNACov tshuaj uas muaj genotoxic tuaj yeem khi ncaj qha rau DNA lossis ua tsis ncaj ua rau DNA puas tsuaj los ntawm kev cuam tshuam cov enzymes koom nrog hauv DNA replication, yog li ua rau kev hloov pauv uas yuav lossis tsis tuaj yeem. ua rau mob qog noj ntshav los yog yug me nyuam tsis xws luag (kev puas tsuaj los ntawm noob neej).
Qhov txawv ntawm genotoxicity thiab carcinogenicity yog dab tsi?
Lo lus "genotoxic carcinogen" qhia tias tshuaj muaj peev xwm ua rau mob qog noj ntshavlos ntawm kev hloov pauv cov caj ces ntawm lub hom phiaj, thaum "non-genotoxic carcinogen" sawv cev rau cov tshuaj muaj peev xwm ntawm ua rau mob qog noj ntshav los ntawm qee qhov kev ua haujlwm thib ob tsis cuam tshuam txog kev puas tsuaj ntawm noob caj noob ces.

Puas yog yug thiab moles yog tib yam?
Moles thiab birthmarks tsis tas yuav yog ib qho tib si, tab sis lawv tuaj yeem yooj yim tsis meej pem vim tias mole tuaj yeem tshwm sim thaum yug. Qee tus kws kho mob xav tias mole yog "kev zoo nkauj" vim nws yog thaj chaw pigmentated.
Puas yog lub tesseract thiab lub pob zeb qhov chaw yog tib yam?
Lub Tesseract, tseem hu ua lub voos xwmfab, yog lub pob zeb crystalline zoo li lub nkoj ntimrau lub Pob Zeb Space, ib qho ntawm rau Lub Pob Zeb Infinity uas ua rau lub ntiaj teb thiab muaj lub zog tsis muaj kev txwv.. Nws tau siv los ntawm ntau yam kev vam meej thaum ub ua ntej los rau hauv Asgardian tes, khaws cia hauv Odin's Vault .
Puas muaj ntau yam thiab ntau yam zoo ib yam?
Kev sib sib zog nqus-qhov sib txawv ntawm qhov nqaim-ntawm cov khoom lag luam txhais tau hais tias tus neeg muag khoom nqa ntau qhov sib txawv ntawm ib yam khoom. Ntau yam-qhov sib txawv ntawm qhov nqaim-ntawm cov khoom txhais tau tias tus neeg muag khoom nqa ntau yam khoom sib txawv.
Puas yog lub kaus mom thiab lub kaus mom yog tib yam?
yog tias helm yog (nautical) lub steering apparatus ntawm lub nkoj, tshwj xeeb tshaj yog lub tiller los yog lub log thaum lub rudder yog (nautical) ib tug underwater vane siv rau steer lub nkoj lub rudder. yog tswj los ntawm lub log, tiller los yog lwm yam khoom siv (hnub no cov hlab ntsha tuaj yeem tswj tau txawm tias muaj lub joystick lossis lub autopilot) .
Puas yog ntau yam tib yam li txhais tau?
Qhov txhais tsis yog ib tus lej tag nrho. Qhov ntau yog qhov txawv ntawm tus lej loj tshaj thiab tus lej tsawg tshaj . IS range also mean? Qhov txawv ntawm qhov qis tshaj thiab qhov siab tshaj plaws. Hauv {4, 6, 9, 3, 7} tus nqi qis tshaj yog 3, thiab qhov siab tshaj plaws yog 9, yog li qhov ntau yog 9 − 3=6.
