Lub lom lub luag hauj lwm ntawm cov dej. lub neej seb puas yog tau tsis muaj dej

Dej - nws yog ib qho tseem ceeb heev ib feem ntawm peb lub neej. Ob feem peb ntawm lub ntiaj teb nto nyob los ntawm cov seas thiab oceans. Txhua yam uas nyob ib ncig peb, yuav tsis muaj nyob tsis muaj tus H ₂ O molecule Txawm cov neeg los ntawm 70 rau ib xees yog ua los ntawm qhov no substance. Lub lom luag hauj lwm ntawm dej yog heev. Koj yuav pom koj tus kheej, yog tias koj nyeem no tsab xov xwm txog rau thaum xaus.

Saib tawm lub qhov rai. Yuav ua li cas koj pom? Cov neeg, tsiaj txhu, nroj tsuag, tsev, tsheb. Tag nrho cov no yog tawm ntawm cov dej, txawm li cas los, nws feem pua ntawm cov tag nrho cov txawv. Yog vim li cas mus deb li deb? Yuav ua li cas koj xav tias cov txha hniav laus thiab cov pob txha muaj yog cov feem ntau amazing molecule H ₂ O? Ntawm cov hoob kawm, tsuas yog lawv feem pua yog heev me me. Nyob rau hauv peb hauj lub sij hawm tsis muaj dej tib neeg yuav tsis ua li cas.

Cov dej molecule

Qhov tsab xov xwm yuav sib tham txog lub zog ntawm cov dej thiab nws lom lub luag hauj lwm. Peb twb hais tias cov kev ua ntawm no substance yog heev heev heev thiab ntau yam. Wb tham me ntsis txog yuav ua li cas rau tsim ib tug qauv, ces nws yuav clear vim li cas qhov no compound yog li ntawd multifunctional thiab universal. Peb pib nrog cov muaj pes tsawg leeg. Cov dej molecule muaj 3 atoms: 2 - 1 thiab ib tug hydrogen - oxygen. Zoo li tus zoo li ib tug ceskaum daim duab peb sab. Xws li ib tug yeeb tshuaj yog ib tug dipole vim hais tias nws muaj polarity. Dej - nws yog ib qho amazing kev twb kev txuas, raws li nws yuav ua tau nyob rau hauv peb lub xeev:

• khoom;
• kua;
• gaseous.

Lub lom luag hauj lwm ntawm dej yog heev. Peb yuav tam sim no mus xav txog lub zog ntawm cov txuj ci tseem ceeb molecule.

kuab

Lub lom luag hauj lwm ntawm dej yog hais tias nws tej zaum yuav zoo yaj ib tug ntau yam ntawm tshuaj. Tab sis qhov no yog ib tug ntawm lub zog. Txij li thaum zoo yam tshuaj uas muaj peev xwm yaj nyob rau hauv dej, ces zoo huv si nrhiav tau qhov no kua yog suab tsis yooj yim sua, nws tseem tau mus extract xwb nyob rau hauv laboratory tej yam kev mob. Tej kuab peev xwm ntawm kev noj nkaus xwb ib tug tej yam muaj pes tsawg tus ntawm tshuaj. Yog li, muaj roj nyeem aqueous lub ntsiab, i.e. thaum tsis muaj ntau kuab yaj thiab coj ib yam khoom uas lwm yam. Tab sis yog hais tias tus dej yog rhuab, nws muaj peev xwm raws li ib tug hnyav nce xav. Ib tug xyaum ua tej yam: yaj tib cov suab thaj los yog ntsev nyob rau hauv kub thiab dej txias. Ntawm cov hoob kawm, nyob rau hauv lub kub xaus tshwm sim sai npaum li cas, thiab yuav muaj ncuav mog qab zib.

thermotaxis

Lub lom luag hauj lwm ntawm dej raws li yog tus muaj peev xwm kom muaj ib tug tsis tu ncua lub cev kub. Uas yog, nyob rau hauv lub txias thiab nyob rau hauv ib tug sov so ib puag ncig ntawm peb lub cev kub (piv txwv tias yog tias tus neeg yog noj qab nyob zoo) yuav nyob twj ywm unchanged - 36,6 degrees. Qhov no yuav ua tau piav los ntawm lub fact tias cov dej yog mus xeem tau tus tshav kub thiab txias cia heev maj mam.

Tam sim no ib tug me ntsis txog dab tsi lub tshav kub. Qhov no pauv ntawm tshav kub ntawm lub cev thiab qhov ib puag ncig. Lub ntsiab zoo tshaj - yog lub cev kub ntawm lub zeej nyob uas yog nyob rau ntawm metabolic dab thiab lub tshav kub tso zis. Muaj ob hom ntawm nyob creatures nyob hauv lub ntiaj teb:

• poikilothermic;
• homoiothermal.

Peb yuav mus rau lub thib ob pab pawg neeg, uas yog, yog sov-blooded. Peb kub tsis txawv nrog kev hloov nyob rau hauv ambient kub.

cell elasticity

Tam sim no hais txog dab tsi lom luag hauj lwm ntawm cov dej nyob hauv lub cell. Raws li hais ua ntej lawm, dej yog lub kuab muab kev koom tes nyob rau hauv tus txheej txheem thermoregulation. Nyob rau hauv tas li ntawd mus rau lub foregoing, nws yog lub hauv paus rau lub organelles ntawm hlwb thiab txhawb nws muaj tseeb daim ntawv no. Qhov no yuav tau piav raws li nram no: Dej yog heev yooj yim mus hlob, txawm nyob rau hauv lub laboratory, nws yuav pab kom muaj lub elasticity ntawm lub hlwb. Yog hais tias koj tsis ntseeg tias nws, ces los so kev: sim nyem cov dej. Pom zoo, nws yog heev yooj yim.

thauj muaj nuj nqi

Lwm feature ntawm dej yog nws muaj peev xwm xa tus tsim nyog cov ntaub ntawv. Tam sim no peb yuav tsom rau cov thauj muaj nuj nqi. Muaj peev xwm mus xa rau qhov tsim nyog ntaub ntawv yog vim lub high nto nro ntawm cov kua. Yog li, dej yuav txeem mus rau hauv cov hlab ntsha, cov intercellular qhov chaw. Hais tias yog, nws muaj lub hwj chim hlwb thiab qhia pliaj yam. Dej muaj ib tug ntau yam ntawm cov khoom, namely lawv yuav tsum tau thov ua tsaug rau cov tua ntawm tag nrho cov tseem ceeb heev functions.

ecological lub luag hauj lwm

Peb tau pom tias dab tsi lom luag hauj lwm ntawm dej, tab sis nws yog ib qho tseem ceeb kom nkag siab txog qhov tseeb hais tias lub ecological lub luag hauj lwm no nws tsis muaj tsis tseem ceeb. Peb yuav paub qhov txawv ob yam:

• ib tug sab nraud ib puag ncig zoo tshaj;
• nrog ib puag ncig tau.

Lwm yam xws li ib tug xov tooj ntawm cov nta, xws li kev nyab xeeb, kev nyab xeeb, tej vaj tse, thiab hais txog. Domestic tej yam feem ntau nyob rau hauv lub hlwb uas muaj sia nyob. Yog li ntawd, ib tug yuav paub ib tug xov tooj ntawm cov nta thiab tus txheej txheem uas dej yog muab kev koom tes. Muaj ntau ntawm cov kev khiav dej num tseem ceeb heev rau tib neeg beings.
