Peb yam tseem ceeb txiav txim siab cell zoo li : lub xeev ntawm lub cytoskeleton, tus nqi ntawm cov dej uas yog pumped rau hauv a cell , thiab lub xeev ntawm cov cell phab ntsa. Txhua yam ntawm peb yam no yog qhov muaj zog heev, txhais tau tias lawv tsis tu ncua hauv flux lossis tuaj yeem hloov pauv sai sai. Qhov no dynamism yog li cas hlwb tuaj yeem sib txawv hauv puab.
Kuj kom paub yog, dab tsi txiav txim siab cov duab ntawm lub cell?
Lub Cytoskeleton Nws muab cov cell nws puab . Lub cytoskeleton yog ib qho kev txav peb-dimensional (3-D) qauv uas sau cov cytoplasm.
Ib yam li ntawd, cov nroj tsuag tuaj yeem hloov cov duab? Nroj tsuag hlwb hloov lawv puab Nrog kev pab ntawm endosmosis thiab exosmosis. Qhov no txhais li cas yog lawv ua tau lawv puab los ntawm hloov nyob rau hauv tus nqi ntawm cov dej tam sim no nyob rau hauv lawv. Vim tsis muaj nqaij fiber ntau thiab muaj nyob ntawm cog -raws li ntaub so ntswg, qhov no yog tib txoj kev uas lawv hloov tau lawv puab.
Ib tug kuj yuav nug, cov hlwb puas yuav hloov pauv thaum lub sijhawm kev loj hlob?
Ntawm Kev loj hlob thiab Daim ntawv.]. Raws li cov cell yog lub functional unit ntawm tej ntaub so ntswg nyob, tag nrho kev hloov pauv hauv lub cev yog tsav los ntawm cov xwm txheej ntawm lub cellular qib. Hauv ua ke nrog cell kev faib, kev loj hlob thiab tuag, hloov hauv tus kheej cell zoo li yog lub hauv paus rau morphogenesis.
Muaj pes tsawg lub hlwb nyob hauv tib neeg lub cev?
Cov kws tshawb fawb xaus lus tias qhov nruab nrab tib neeg lub cev muaj kwv yees li 37.2 trillion hlwb ! Tau kawg, koj lub cev yuav muaj ntau los yog tsawg hlwb tshaj qhov tag nrho, nyob ntawm seb koj qhov loj npaum li cas piv rau qhov nruab nrab tib neeg yog, tab sis qhov ntawd yog qhov pib zoo rau kev kwv yees tus naj npawb ntawm hlwb hauv koj tus kheej lub cev !

Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Dab tsi tsim cov roj siab thiab nws hloov pauv li cas nrog kev hloov pauv hauv kinetic zog?
Gas siab yog tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv roj nrog rau sab hauv ntawm lub thawv thaum lawv sib tsoo nrog thiab tawm dag zog rau ntawm phab ntsa ntim. Tom qab ntawd cov roj yog cua sov. Raws li qhov kub ntawm cov roj nce, cov khoom tau nce lub zog kinetic thiab lawv cov nrawm nrawm
Thaum ib qho kev sib cais ua rau muaj kev hloov pauv hloov pauv ntawm lub ntiaj teb nce ntxiv?
Txij li thaum lub kaw lus raug cais tawm, tsis muaj cua sov tuaj yeem khiav tawm (tus txheej txheem yog li adiabatic), yog li thaum lub zog ntws tawm hauv lub cev, qhov entropy ntawm qhov system nce, piv txwv li Δ Ssys> 0. Yog li ntawd, lub entropy ntawm lub system yuav tsum tau nce rau ib tug spontaneous txheej txheem nyob rau hauv no cais system
Cov kws kos duab hu li cas cov duab thiab cov duab siv los sawv cev rau cov yam ntxwv ntawm lub ntiaj teb nto?
Ntiaj Teb Kev Tshawb Fawb - Daim Ntawv Qhia Lub Ntiaj Teb Qhov Nto A B GLOBE Ib puag ncig uas sawv cev rau lub ntiaj teb nto. SCALE Siv los sib piv qhov deb ntawm daim ntawv qhia lossis lub ntiaj teb mus deb ntawm lub ntiaj teb nto. SYMBOLS Ntawm daim duab qhia chaw, cov duab siv los ntawm mapmakers sawv ntsug rau cov yam ntxwv ntawm lub ntiaj teb nto. TSEEM CEEB Ib daim ntawv teev cov cim siv rau ntawm daim ntawv qhia
Qhov kev hloov pauv twg yuav hloov daim duab A rau hauv daim duab B?
Ob daim duab tau hais tias yuav sib haum xeeb yog tias ib tus tuaj yeem tau txais los ntawm lwm tus los ntawm ib ntu ntawm kev txhais lus, kev xav, thiab kev sib hloov. Cov duab sib xws muaj qhov loj thiab zoo tib yam. Txhawm rau hloov daim duab A rau hauv daim duab B, koj yuav tsum xav txog nws hla y-axis thiab txhais ib chav nyob rau sab laug
