Hauv lub neej voj voog ntawm kev sib deev kis tus kab mob hu ua fungus, theem haploid hloov nrog qib diploid. The haploid theem xaus nrog nuclear fusion, thiab theem diploid pib nrog kev tsim zygote (diploid cell ua los ntawm fusion ntawm ob haploid cells)
Kev sib raug zoo ntawm kev loj hlob ntawm tes thiab kev tsim tawm ntawm tes yog dab tsi?
Thaum lub sij hawm Binary fission thiab mitosis theej tawm cov DNA cov ntsiab lus ntawm kev tsim cov niam txiv ntawm tes tau muab cais ua ob qhov sib npaug sib luag uas yog lub hom phiaj kom xaus rau hauv ob tus ntxhais ntxhais. Ib feem kawg ntawm cov txheej txheem ntawm kev tsim cov cell yog faib cell, thaum tus ntxhais lub cev lub cev sib cais los ntawm niam txiv ntawm tes
Xyoo 1976 Kev Kho Kho Mob Kho Mob tau tsim dab tsi?
Cov ntaub ntawv dav dav. Txoj Cai Kho Mob Kho Mob ntawm Xyoo 1976 rau Tsoom Fwv Teb Chaws Khoom Noj, Tshuaj, thiab Tshuaj Kho Kom Zoo Nkauj (txoj cai) tau tsim peb chav kawm tswj hwm rau cov khoom siv kho mob.
