| Dab tsi yog tus naj npawb ntawm chromosomes rau haploid pea cog hlwb ? | 7 |
| Dab tsi yog tus naj npawb ntawm chromosomes rau diploid orangutan hlwb ? | 48 |
| Tus lej yog dab tsi ntawm hlwb rau Diploid dog hlwb ? | 78 |
Tseem yuav paub yog, muaj pes tsawg chromosomes yuav ib haploid pea cog cell muaj?
diploid pea cog cell muaj 14 chromosomes . Muaj pes tsawg chromosomes yuav muaj haploid pea cog cell?
Ib yam li ntawd, puas yog lub paj hlwb haploid lossis diploid? Hauv tib neeg lub cev, paj hlwb cell yog haploid los yog diploid . Hauv tib neeg lub cev, gamete hlwb yog haploid los yog diploid.
Yog li ntawd, pes tsawg chromosomes nyob rau hauv ib tug haploid cell?
Haploid piav a cell uas muaj ib txheej ntawm chromosomes . Lub sij hawm haploid tuaj yeem xa mus rau tus lej ntawm chromosomes hauv qe los yog phev hlwb , uas tseem hu ua gametes. Hauv tib neeg, gametes yog hlwb haploid uas muaj 23 chromosomes , txhua yam uas ib tug ntawm ib chromosome khub uas muaj nyob rau hauv diplod hlwb.
Vim li cas nws tseem ceeb uas gametes hlwb tsuas muaj ib pawg chromosomes xwb?
Yog li ntawd thaum ob gametes tuaj ua ke, lawv chromosomes ua ke ua rau diploid (2n) tus naj npawb ntawm chromosomes.

Tus naj npawb ntawm chromosomes hauv tus ntxhais cell piv li cas?
Yuav ua li cas cov ntxhais cell piv rau niam txiv cell? Npaj rau mitosis, ib lub cell tsim ib daim qauv ntawm nws DNA. Thaum lub sij hawm mitosis, DNA coils rau hauv condensed chromatid khub hu ua chromosomes. Homologous khub tau sib cais, thiab ob lub hlwb ua rau tus ntxhais muaj ib nrab ntawm ntau chromosomes ib lub xov tooj ntawm tes
Dab tsi yog tus naj npawb ntawm subatomic hais hauv atom ntawm B11?
Tom qab ntawd tus lej loj yog tag nrho cov protons ntxiv rau neutrons. Rau boron-11 tag nrho cov no yog 11, thiab tsib ntawm cov hais yog protons, yog li 11− 5 = 6 neutrons
Tus naj npawb ntawm cov hlwb tsim hauv meiosis yog dab tsi?
Plaub tus ntxhais
Dab tsi yog tus naj npawb ntawm protons hauv atom ntawm silicon nrog cov lej loj tshaj plaws?
Piv txwv li, silicon muaj 14 protons thiab 14 neutrons. Nws atomic tooj yog 14 thiab nws atomic mass yog 28. Qhov feem ntau isotope ntawm uranium muaj 92 protons thiab 146 neutrons. Nws atomic tooj yog 92 thiab nws atomic mass yog 238 (92 + 146). 2.1 Electrons, Protons, Neutrons, thiab Atoms. Element Iron Symbol Fe Number of Electrons in Txhua Plhaub Thawj 2 Thib Ob 8 Peb 14
Dab tsi yog tus naj npawb ntawm chromosomes hauv lub cell haploid?
Lub haploid cell uas muaj tus lej haploid, uas yog tus naj npawb ntawm chromosomes pom nyob rau hauv lub nucleus uas tsim ib txheej. Hauv tib neeg, cov hlwb haploid muaj 23 chromosomes, piv rau 46 hauv cov hlwb diploid. Muaj qhov sib txawv ntawm cov hlwb haploid thiab monoploid
