Ob txoj kev faib, meiosis I thiab meiosis II, yuav tsum tsim gametes (Daim duab 3). Meiosis I yog ib qho kev faib ntawm tes tshwj xeeb uas tshwm sim hauv cov kab mob nkaus xwb; meiosis II zoo ib yam li kev faib mitotic.
Muaj pes tsawg qhov kev faib tshwm sim hauv mitosis thiab meiosis?
Mitosis cuam tshuam txog kev faib cell, whereas meiosis cuam tshuam nrog ob lub cell division.
Yuav muaj pes tsawg faib meiosis?
Meiosis muaj ob lub xov tooj sib cais faib , txhais tau tias ib tus niam txiv cell tuaj yeem tsim tau plaub gametes (qe in poj niam, phev in txiv neej). In txhua puag ncig ntawm division, cov hlwb mus txog plaub theem: prophase, metaphase, anaphase, thiab telophase.
Puas yog mitosis muaj 2 pawg?
Mitosis yog ib qho kev faib tawm nuclear uas ua rau ob lub nuclei, feem ntau muab faib ua ob lub hlwb tshiab. Cov nuclei uas tshwm sim los ntawm kev faib mitotic yog cov noob caj noob ces zoo ib yam li qub. Lawv muaj tib tus lej ntawm cov chromosomes: ib qho ntawm cov hlwb haploid, thiab ob qho ntawm cov hlwb diploid.
Puas yog ob txoj kev faib cell tshwm sim hauv mitosis lossis meiosis?
Cells faib thiab rov tsim dua ob txoj hauv kev, mitosis thiab meiosis. Mitosis ua rau ob lub hlwb zoo tib yam, thaum meiosis tshwm sim hauv plaub lub hlwb. Hauv qab no peb qhia txog qhov sib txawv ntawm cov yuam sij thiab qhov zoo sib xws ntawm ob hom kev faib ntawm tes.

Thaum twg qhov kev rov tshwm sim tshwm sim?
Thaum Replevin tuaj yeem thov Li no, qhov no yog qhov xwm txheej tshwm sim ntau tshaj plaws uas yuav tshwm sim thaum tus neeg siv khoom tsis raug them nyiaj qiv tsheb. Kev ua txhaum cai ntawm kev thaj yeeb nyab xeeb yog me ntsis luv luv. Nws tsis suav nrog kev txeeb tsheb yam tsis tau ceeb toom lossis kub xov tooj kom tsav tsheb mus.
Qhov kev tshwm sim hauv lub neej tseem ceeb ntawm kev ntsuas kev ntsuas kev sib raug zoo twg muaj tus lej ntau tshaj?
Qhov kev tshwm sim ntawm qib siab tshaj yog tuag ntawm tus txij nkawm(nrog tus nqi nruab nrab ntawm 100), txheeb ze rau kev sib yuav, nrog tus nqi nruab nrab ntawm 50, thiab, piv txwv, kev tuag ntawm tus phooj ywg ze, uas tau qhab nia 37. Qhov xwm txheej tseem ceeb ntawm lub neej ntawm Kev Hloov Kho Kev Ntsuas Kev Ntsuas Qhov Ntsuas puas muaj cov lej hloov pauv lub neej ntau tshaj?
Thaum qhov no yog qhov tshwm sim uas tshwm sim?
Lub hauv paus ntsiab lus ntawm kev mob Nrog qhov tshwm sim (uppada) ntawm qhov no, qhov tshwm sim. Thaum tsis muaj qhov no, qhov ntawd tsis tuaj. Nrog lub cessation (nirodha) ntawm no, uas ceases. - Samyutta Nikaya 12.61. Thaum qhov no yog qhov tshwm sim uas tshwm sim qhov tshwm sim uas tshwm sim thaum qhov no tsis yog qhov tsis yog qhov kev txiav txim siab tsis piav qhia?
Yuav ua li cas txiav txim siab seb qhov kev tshwm sim yog tshwm sim los yog tsis ua raws li txoj cai?
Kev sib xyaw ua lej ntawm kev hloov pauv enthalpy thiab hloov pauv hloov pauv tso cai rau kev hloov pauv ntawm lub zog dawb los suav. A tawm tsam nrog tus nqi tsis zoo rau ΔG tso tawm lub zog dawb thiab yog li nws tus kheej. Cov tshuaj tiv thaiv nrog qhov zoo ΔG yog tsis ua raws li kev xav thiab yuav tsis nyiam cov khoom.
Puas tsis muaj qhov tshwm sim tshwm sim xav tau enzymes?
Tam sim no, enzymes TSIS ua rau cov tshuaj tiv thaiv tsis yog tus kheej. Txawm li cas los xij, enzymes ua kom nrawm nrawm ntawm cov tshuaj tiv thaiv tus kheej. Yeej, lawv ua kom cov tshuaj tiv thaiv sai dua. Enzymes ua qhov no los ntawm kev txo qis kev ua kom lub zog ntawm cov tshuaj tiv thaiv.
