Lub hauv paus ntsiab lus thoob ntiaj teb "los ntawm qhov yooj yim mus rau qhov nyuaj" siv tau rau txhua theem ntawm lub koom haum paub txog qhov teeb meem thiab tshwm sim nws tus kheej ntawm txhua qhov ntawm nws cov kauj ruam hauv daim ntawv ntawm ib theem ntawm lub koom haum.
Txhua lub cev muaj sia yog lub kaw lus txawb qhib rau kev sib cuam tshuam nrog ib puag ncig sab nraud. Lub ntsiab "cov ntaub ntawv tsim" ntawm cov cell muaj sia yog cov proteins, lipids, carbohydrates, nucleic acids.
Levels of organization of multicellular kab mob
Qib molecular ntawm lub koom haum ntawm cov khoom nyob yog qhov yooj yim tshaj plaws thiab muaj nyob hauv txhua yam kab mob nyob, los ntawm cov kab mob mus rau protozoa. Cov tshuaj tiv thaiv uas ua rau muaj kev txhawb nqa lub neej muaj nyob rau ntawm nws, thiab cov kev pab cuam cuam tshuam nrog cov nucleic acids kuj tau siv. Tom ntej no yog qib cellularlub koom haum ntawm cov khoom muaj sia - muaj cov khoom sib txawv me ntsis. Nws yog lub xovtooj ntawm tes uas yog qhov tsawg kawg nkaus chav tsev ntawm cov khoom muaj sia, muab nws nrog cov haujlwm tseem ceeb xws li kev loj hlob, kev loj hlob, thiab kev yug me nyuam. Cov txheej txheem metabolic tshwm sim hauv cov hlwb.
Levels of organization of multicellular kab mob
Zoo ib yam hauv cov qauv thiab kev ua haujlwm, cov hlwb tsim plaub hom ntaub so ntswg: txuas, epithelial, paj hlwb, thiab cov leeg. Ntau hom ntaub so ntswg, ib los yog ob qho uas ua lub luag haujlwm tseem ceeb dua, tsim ib lub cev - ib feem ntawm lub cev uas muaj qhov chaw muab thiab ua tiav qee yam haujlwm. Cov kab ke hauv nruab nrog cev tau sib xyaw ua ke, tsim kom muaj qib tshiab ntawm lub koom haum ntawm cov khoom muaj sia - kab mob; Nws yog nyob rau hauv feem ntau nyob rau hauv multicellular creatures. Txhua yam kab mob yog ib qho kev ruaj khov, muaj kev ywj pheej ntawm ib puag ncig thiab tuaj yeem hloov kho rau nws cov xwm txheej. Vim lub fact tias cov kab mob nyob rau hauv tib hom muaj ib tug zoo xws li cov qauv thiab kev ua hauj lwm, lawv muaj peev xwm sib sau ua ke nyob rau hauv cov pejxeem, nyob rau hauv tej thaj chaw, uas yog yus muaj los ntawm tej yam kev nyab xeeb nta.
Ua qhov yooj yim tshaj plaws ntawm cov txheej txheem evolutionary, cov pej xeem ua kom muaj kev sib pauv ntawm cov ntaub ntawv caj ces, cov txheej txheem ntawm kev hloov pauv thiab hloov pauv. Biocenoses, uas yog cov koom haum ntawm cov pej xeem ntawm ntau hom, los ntawm kev sib cuam tshuam nrog oc
ib puag ncig nyob rau qib tom ntej ntawm lub koom haum ntawm cov teeb meem nyob. Nws yog biogeocenosis uas ua kom cov kev ncig ntawm cov khoom uas muaj nyob rau hauv cov xwm txheej, nrog rau kev sib cuam tshuam ntau tshaj plaws ntawm cov tsiaj txhu thiab cov tsiaj tsis muaj sia.
Qhov siab tshaj plaws uas twb muaj lawm ntawm lub koom haum ntawm cov teeb meem nyob - biospheric - koom ua ke biogeocenoses. Nws muaj ib qho kev khiav ntawm lub zog, thiab tseem muab tag nrho cov theem saum toj no rau hauv ib qho tag nrho. Nws yog qib no ntawm lub koom haum ntawm cov teeb meem nyob uas muaj ntau yam kev ua haujlwm, uas suav nrog kev tswj xyuas qhov tsis tu ncua ntawm sab nraud thiab sab hauv cov qauv ntawm kev ua neej nyob, kev tsim kho thiab systematizing nws cov ntsiab lus tseem ceeb.
