Lub voj voog ntawm tes muaj peb theem uas yuav tsum tshwm sim ua ntej mitosis, los yog cell division, tshwm sim. Cov no peb theem yog collectively hu ua interphase . Lawv yog G1, S, thiab G2. G sawv rau qhov sib txawv thiab S sawv rau kev sib txuas.
Sib tham, yuav ua li cas tshwm sim thaum lub sij hawm 3 theem ntawm interphase?
Muaj peb theem ntawm interphase : G1 (thawj qhov sib txawv), S (synthesis ntawm DNA tshiab), thiab G2 (thib ob qhov sib txawv). Cells siv feem ntau ntawm lawv lub neej hauv interphase , tshwj xeeb hauv tus S theem qhov twg cov khoom siv caj ces yuav tsum tau theej. Lub cell loj hlob thiab ua haujlwm biochemical, xws li protein synthesis, hauv lub G1 theem.
Tom qab ntawd, lo lus nug yog, dab tsi tshwm sim hauv txhua theem ntawm interphase? Interphase yog tsim los ntawm G1 theem (kev loj hlob ntawm tes), ua raws li S theem (DNA synthesis), ua raws li G2 theem (kev loj hlob ntawm tes). Thaum kawg ntawm interphase los ntawm mitotic theem , uas yog tsim los ntawm mitosis thiab cytokinesis thiab ua rau kev tsim ntawm ob tug ntxhais hlwb.
Hais txog qhov no, dab tsi tshwm sim thaum g1 theem ntawm interphase?
Cov G1 Phase feem ntau hu ua kev loj hlob theem , vim lub sijhawm no hauv uas ib tug cell loj hlob. Thaum qhov no theem , lub cell synthesizes ntau yam enzymes thiab cov as-ham uas xav tau tom qab rau DNA replication thiab cell division. Cov G1 Phase kuj yog thaum cov hlwb tsim cov protein ntau.
Tus txheej txheem ntawm interphase yog dab tsi?
Thaum interphase , lub cell luam nws DNA hauv kev npaj rau mitosis. Interphase yog 'kev ua neej nyob txhua hnub' lossis theem metabolic ntawm lub cell, uas lub cell tau txais cov as-ham thiab metabolizes lawv, loj hlob, nyeem nws cov DNA, thiab ua lwm yam "ib txwm" cell functions.

Dab tsi yog equidistant los ntawm peb sab ntawm daim duab peb sab?
Lub ntsiab lus uas sib npaug rau txhua sab ntawm daim duab peb sab yog hu ua incenter: Ib qho nruab nrab yog ib qho kab uas muaj ib qho ntawm nws qhov kawg ntawm lub vertex ntawm daim duab peb sab thiab lwm qhov kawg ntawm qhov nruab nrab ntawm sab opposite lub vertex. Peb qhov nruab nrab ntawm ib daim duab peb sab sib ntsib hauv centroid
Dab tsi yog g2 theem ntawm interphase?
Qhov kawg ntawm interphase hu ua G2 theem. Lub xovtooj tau loj hlob, DNA tau rov ua dua, thiab tam sim no lub xovtooj yuav luag npaj los faib. Qhov kawg theem no yog txhua yam hais txog kev npaj cov cell rau mitosis lossis meiosis. Thaum lub sij hawm G2, lub cell yuav tsum loj hlob ib co ntxiv thiab tsim tej molecules nws tseem yuav tsum tau faib
Ob theem tseem ceeb ntawm photosynthesis yog dab tsi thiab txhua theem tshwm sim nyob qhov twg?
Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent kev tshwm sim thiab lub Calvin voj voog (lub teeb-yooj yim kev xav). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH
Dab tsi tshwm sim hauv S theem ntawm interphase?
S theem ntawm lub voj voog ntawm tes tshwm sim thaum lub sij hawm interphase, ua ntej mitosis los yog meiosis, thiab yog lub luag hauj lwm rau cov synthesis los yog replication ntawm DNA. Nyob rau hauv txoj kev no, cov khoom siv caj ces ntawm lub xov tooj ntawm tes yog ob npaug ua ntej nws nkag mus rau mitosis lossis meiosis, cia kom muaj DNA txaus los faib rau hauv cov menyuam ntxhais
Dab tsi yog qhov voltage ntawm ob theem hauv 3 theem khoom?
Voltage ntawm ob theem hu ua Kab voltage. Kab voltage = 1.73 * Phase voltage. Hluav taws xob hluav taws xob nruab nrab ntawm ib theem 'nyob' thiab 'tsis nruab nrab' hauv peb theem kev faib tawm yog 220 V
