Somatic hlwb raug tsim dhau ntawm cov txheej txheem cell faib ntawm mitosis. Lawv muaj ob daim ntawv theej ntawm txhua tus chromosome, ib qho los ntawm lub cev niam thiab ib qho los ntawm lawv txiv. Cells uas muaj ob daim ntawv luam ntawm txhua chromosome hu ua diploid.
Puas yog somatic hlwb tsim los ntawm meiosis?
Somatic cov hlwb-uas yog, cov hlwb hauv koj lub cev uas tsis yog kev sib deev-ua li no ntawm tus txheej txheem hu ua mitosis. Cov hlwb tshiab, lossis gametes, yog tsim los ntawm cov txheej txheem sib txawv, hu ua meiosis.
theem twg tsim cov hlwb somatic?
S theem yog lub sijhawm ntawm kev lag luam DNA synthesis thaum lub xovtooj rov ua dua nws cov ntsiab lus caj ces; ib txwm diploid somatic cell nrog 2N ntxiv ntawm DNA thaum pib ntawm S theem tau txais 4N ntxiv ntawm DNA ntawm nws qhov kawg.
Dab tsi ua rau cov hlwb somatic?
Somatic, lossis lub cev hlwb, xws li cov uas ua rau ntawm daim tawv nqaij, plaub hau, thiab cov leeg, yog duplicated los ntawm mitosis. Cov kab mob sib deev, phev thiab ov, yog tsim los ntawm meiosis nyob rau hauv cov ntaub so ntswg tshwj xeeb ntawm txiv neej testes thiab poj niam zes qe menyuam.. Txij li thaum feem coob ntawm peb cov hlwb yog somatic, mitosis yog cov feem ntau ntawm cov cell replication.
Puas yog mitosis siv los tsim cov hlwb somatic?
Ob qho tib si kev sib deev thiab cov kab mob sib deev mus dhau ntawm cov txheej txheem ntawm mitosis. Nws tshwm sim hauv cov hlwb ntawm lub cev hu ua somatic cellsthiab tsim cov hlwb ntsig txog kev loj hlob thiab kho. Mitosis yog qhov tseem ceeb rau asexualkev loj hlob, kev tsim dua tshiab, thiab kev loj hlob.
Gametic vs. Somatic Cell

Cov hlwb twg tsim nyog rau kev kho cov hlab ntsha thiab txhaws?
Qhov tseem ceeb ntawm hemostasis Ib txwm hemostasis yog lub luag haujlwm ntawm cov txheej txheem nyuaj ntawm peb tus kheej cov khoom: cov qe ntshav (platelets), cov hlwb uas kab cov hlab ntsha (cov hlwb endothelial), thiab ntshav proteins (blood-clotting proteins).
Lub sijhawm somatic hybridization hlwb raug kho nrog?
Cov txheej txheem ntawm kev tsim cov somatic hybrids (fusion ntawm hlwb ntawm ob hom ntawm hom) los ntawm polyethylene glycol (PEG) yog hu ua somatic hybridization. Cov nroj tsuag tsis muaj cell phab ntsa hu ua protoplast. Kev sib cais ntawm protoplasts yog ua los ntawm kev kho cov hlwb nrog pectinase thiab cellulase enzymes.
Puas yog cov paj hlwb genitofemoral yog cov paj hlwb peripheral?
Cov paj hlwb genitofemoral hais txog paj hlwb uas pom hauv plab. Nws cov ceg, ceg ntawm qhov chaw mos thiab cov ceg femoral muab kev nkag siab rau sab sauv sab xub ntiag, nrog rau daim tawv nqaij ntawm lub qhov quav sab hauv ntawm cov txiv neej thiab mons pubis hauv cov poj niam.
Cov hlwb twg tsim cov testosterone?
Leydig cells Leydig cells Anatomical terminology. Leydig hlwb, tseem hu ua interstitial hlwb ntawm Leydig, pom nyob ib sab mus rau seminiferous tubules nyob rau hauv testicle. Lawv tsim testosterone nyob rau hauv lub xub ntiag ntawm luteinizing hormone (LH).
Pob hlwb hlwb rov tsim dua?
Cov ntsiab lus: Thaum cov neeg laus lub hlwb raug mob, lawv rov qab mus rau lub xeev embryonic, hais tias cov kws tshawb fawb. Nyob rau hauv lawv lub xeev tshiab uas tsis paub tab, cov hlwb muaj peev xwm ntawm rov loj hlob tshiab kev sib txuas uas, raws li txoj cai, tuaj yeem pab rov qab ua haujlwm poob.
