Yog li ntawd, plaub yam tseem ceeb ntawm lub neej yog dab tsi?
Txhua yam kabmob muaj sia muaj ntau yam tseem ceeb lossis kev ua haujlwm: kev txiav txim, rhiab lossis teb rau ib puag ncig, kev yug me nyuam , kev loj hlob thiab kev loj hlob, kev cai, homeostasis, thiab lub zog ua haujlwm. Thaum saib ua ke, cov yam ntxwv no pab txhais lub neej.
Ib sab saum toj no, qhov twg hauv qab no yog suav tias yog ib qho ntawm lub neej? Hmoov zoo, biologists tau tsim cov npe ntawm yim tus yam ntxwv sib koom los ntawm txhua yam muaj sia. Cov yam ntxwv yog qhov zoo lossis qhov zoo. Cov yam ntxwv no yog lub koom haum cellular, kev yug me nyuam, metabolism, homeostasis , heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution.
Raws li txoj cai, cov yam ntxwv ntawm lub neej quizlet yog dab tsi?
Lub koom haum, kev tsim tawm, kev hloov pauv, kev loj hlob thiab kev loj hlob, DNA, lub zog, homeostasis, evolution.
Dab tsi yog ib qho ntawm tsib yam ntxwv ntawm lub neej quizlet?
Nyob cov khoom xav tau dej, zaub mov thiab huab cua (ntxiv rau lwm cov as-ham rau lub neej txheej txheem). Kev loj hlob yog tus txheej txheem ntawm kev loj hlob. Kev loj hlob yog tus txheej txheem ntawm kev hloov pauv uas tsim ib complex kab mob. Cov kab mob hloov mus rau qhov chaw hloov pauv. Tej yam hauv ib puag ncig uas ua rau ib yam dab tsi tshwm sim.

Dab tsi yog plaub yam tseem ceeb uas txhua tus tsiaj sib koom?
Tab sis raws li ntau haiv neeg, tsiaj muaj plaub yam tseem ceeb uas tau muab ua ke cais lawv ntawm lwm yam kab mob (Daim duab 23-1). Tsiaj txhu yog eukaryotic. Tsiaj cell tsis muaj cov phab ntsa ntawm tes. Tsiaj txhu yog multicellular. Tsiaj txhu yog heterotrophs uas noj zaub mov
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Qhov twg ntawm cov plaub hau plaub hau yog ib txwm plaub hau plaub hau?
square Tsis tas li ntawd nug, qhov ntsuas ntawm ib lub quadrilateral tsis tu ncua yog dab tsi? Yog, sab hauv lub kaum sab xis ntawm txhua lub ces kaum ntawm ib lub quadrilateral tsis tu ncua yog txhua 90 degrees (360 degrees / 4 fab).
Dab tsi yog qhov txawv ntawm keeb kwm ntawm lub neej thiab lub neej voj voog?
Lub neej keeb kwm yog kev tshawb fawb txog kev xeeb tub cov tswv yim thiab cov yam ntxwv. Piv txwv ntawm lub neej keeb kwm zoo muaj xws li hnub nyoog ntawm thawj kev yug me nyuam, lifespan, thiab tus naj npawb vs loj ntawm cov xeeb ntxwv. Lub neej voj voog ntawm hom yog tag nrho ntawm cov theem thiab tsim cov kab mob mus dhau nws txoj sia
