Cov yam uas txwv qhov loj ntawm cov cell muaj xws li: Qhov chaw saum npoo rau ntim ratio ( thaj chaw saum npoo / ntim ) Nucleo-cytoplasmic ratio. Fragility ntawm cell membrane.
Hais txog qhov no, dab tsi yog 3 yam uas txwv cell loj?
Cov xwm txheej txwv qhov loj ntawm cov cell muaj xws li:
- Qhov chaw thaj tsam rau qhov ntim piv. (surface area / ntim)
- Nucleo-cytoplasmic ratio.
- Fragility ntawm cell membrane.
- Cov qauv siv tshuab tsim nyog los tuav lub cell ua ke (thiab cov ntsiab lus ntawm lub xov tooj ntawm qhov chaw)
Ib tug kuj yuav nug, ntawm dab tsi yam zoo li cas thiab qhov loj ntawm cell nyob ntawm? Cov duab thiab qhov loj ntawm cell nyob ntawm qhov muaj nuj nqi nws ua. Rau piv txwv , RBCs yog tsim nyob rau hauv xws li ib txoj kev uas lawv yuav tsum nqa oxygen nyob rau hauv daim ntawv khi nrog hemoglobin. Nucleus occupies txaus qhov chaw nyob rau hauv lub cell. Yog li, RBCs tsis muaj nucleus txhawm rau kom haum rau hemoglobin ntau dua oxygen.
Yog li ntawd, cov cell yuav kov yeej cov kev txwv loj li cas?
Lub ntsiab lus tseem ceeb yog qhov chaw saum npoo rau qhov ntim piv tau me dua li qhov cell tau loj dua. Yog li ntawd, yog hais tias tus cell loj hlob dhau ib qho txwv , tsis txaus cov khoom yuav muaj peev xwm hla lub membrane sai txaus kom haum rau qhov nce cellular ntim.
Lub cell loj npaum li cas hais txog qhov loj ntawm lub cev?
Tsis muaj kev sib raug zoo ntawm cov qhov loj ntawm cell mus rau qhov loj ntawm kab mob nyob rau hauv cov ntaub ntawv ntawm Multicellular kab mob . Txawm li cas los xij, nyob rau hauv rooj plaub ntawm Unicellular, Prokaryotes, tsuas muaj ib qho xwb cell thiab li no loj dua cell , loj yog cov kab mob.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
