Qhov feem ntau hom ntawm kev yug me nyuam asexual siv los ntawm protozoa yog binary fission . Hauv binary fission , cov kab mob duplicates nws cov xov tooj ntawm tes thiab ces faib nws tus kheej mus rau hauv ob yam kab mob. Ob daim ntawv ntawm kev yug me nyuam asexual siv los ntawm protozoa yog hu ua budding thiab schizogony.
Ib yam li ntawd, protozoa yug me nyuam li cas?
Protozoa yug me nyuam los ntawm ob qho tib si asexual thiab kev sib deev txhais tau tias, txawm tias kev sib deev kev yug me nyuam tsis tshua muaj tshwm sim thiab tshwm sim hauv qee pawg. Feem ntau protozoa yug me nyuam asexually los ntawm cell division ua ob sib npaug los yog tej zaum tsis sib npaug hlwb. Hauv qee qhov protozoa Ntau qhov fission lossis schizogamy paub tias tshwm sim.
Ib yam li ntawd, kev tshawb fawb ntawm protozoa yog dab tsi? Protozoology, ua kawm txog cov protozoans . Kev tshawb fawb tau pib nyob rau hauv ib nrab ntawm lub xyoo pua 17th thaum Antonie van Leeuwenhoek ntawm Netherlands thawj zaug pom. protozoans los ntawm txoj kev ntawm nws invention, lub microscope.
Ntawm no, dab tsi yog protozoa hauv cov lus yooj yim?
Protozoa me me (tab sis tsis yog yooj yim ) cov kab mob. Lawv yog ib leeg -celled heterotrophic eukaryotes, uas noj cov kab mob thiab lwm yam khoom noj. Nws yog ib qho yooj yim tuav-txhua lub sij hawm, tab sis ua tau ' protozoa ' raug cais nyob rau hauv ib tug xov tooj ntawm txawv phyla.
Lub luag haujlwm ntawm protozoa yog dab tsi?
Lub cell protozoan nqa tawm tag nrho cov txheej txheem-xws li kev pub mis, kev loj hlob, kev loj hlob, kev tsim tawm, thiab kev txav mus los-tsim nyog los txhawb nqa thiab nthuav tawm lub neej. Lub cell yog nyob rau hauv ib daim nyias nyias hu ua lub ntshav ntshav daim nyias nyias.

Dab tsi yog lub tswv yim ntawm kev txhawb nqa ntawm kev sib cais ntawm kev sib deev?
Kev txhawb zog yog cov txheej txheem los ntawm kev xaiv ntuj tsim kom muaj kev sib cais ntawm kev sib deev. Kev txhawb zog tuaj yeem tshwm sim raws li hauv qab no: Thaum ob pawg neeg uas tau khaws cia sib nrug, rov qab los rau hauv kev sib cuag, qhov kev sib cais ntawm cov menyuam yaus yuav ua tiav lossis tsis tiav. Yog tias nws ua tiav, speciation tau tshwm sim
Dab tsi yog qhov tseem ceeb ntawm kev tawm hauv cov crystal kev loj hlob tsis muaj kev cuam tshuam?
Nws yog ib qho tseem ceeb uas yuav tsum tau ua kom qhov kev sim npog kom tsis txhob muaj plua plav thiab lwm yam khoom siv tsis xav tau los ntawm kev cuam tshuam kev loj hlob siv lead ua. Saib xyuas kev tsim cov muaju ntawm cov hlua txhua hnub. Sab laug tsis muaj kev cuam tshuam, cov muaju yuav tsum loj dua txhua hnub kom txog thaum cov tshuaj qhuav qhuav
Dab tsi yog qhov txawv ntawm kev xaiv khoom tsim thiab kev tsim noob caj noob ces?
Artificial xaiv xaiv rau cov yam ntxwv uas twb muaj nyob rau hauv ib hom, whereas genetic engineering tsim cov yam ntxwv tshiab. Hauv kev xaiv dag, cov kws tshawb fawb yug tsuas yog cov tib neeg uas xav tau qhov zoo. Los ntawm kev xaiv kev yug me nyuam, cov kws tshawb fawb muaj peev xwm hloov cov cwj pwm hauv cov neeg. Evolution tau tshwm sim
Lub hom phiaj ntawm kev tsim tawm ntawm tes yog dab tsi?
Lub hom phiaj ntawm Cell Division. Kev faib tawm ntawm tes yog txheej txheem tseem ceeb rau lub cev tsim, kev loj hlob, thiab kho. Muaj ob hom kev faib cell hauv tib neeg. Cells tuaj yeem faib ua cov qe, cov phev thiab qe
Cov tshuaj dab tsi tuaj yeem txav mus rau hauv lossis tawm ntawm cov hlwb los ntawm kev nthuav tawm?
Dej, carbon dioxide, thiab oxygen yog ib qho ntawm ob peb yam yooj yim molecules uas muaj peev xwm hla lub cell membrane los ntawm diffusion (los yog ib hom diffusion hu ua osmosis). Diffusion yog ib txoj hauv kev ntawm kev txav ntawm cov khoom nyob rau hauv cov hlwb, nrog rau txoj kev rau cov me me molecules tseem ceeb hla lub cell membrane
