Homeostasis - kukugcina eseleyo imvelo

Homeostasis - ukukwazi kwenkqubo ephilayo ukugcina rhoqo kakhulu silungelelene olutshintshayo kokusingqongileyo lwangaphakathi. Eli binzana of imvelaphi yamaGrike. Kuye isakhiwo ezintsonkothileyo lisekwa amagama amabini - homoios (ezifanayo) kunye stasis (zikarhulumente). Iindlela ukuzeyisa ukuqinisekisa rhoqo lwe bokuphila, ebizwa homeostatic. Kuxhomekeka isakhiwo lwangaphakathi inkqubo evulekileyo nentsebenziswano yawo kunye nokusingqongileyo, esisigxina ixhasa iindlela ezinjalo yi ezahlukeneyo:

- Ukungazinzi phantsi kwemiqathango yale nkqubo iqinisekisa ukuba bhetyebhetye ubuninzi imiqathango efunekayo;

- ukulwela ukuba balance nokulondolozwa kunceda ukuba silondoloze ukulinganisela usisizalwane lwesakhiwo kunye nombutho ukusebenza kwenkqubo;

- ukusebenza neqembu kuvumela azimiseleyo ukuze kuphunyezwe iziphumo ezintsha negalelo oluqhubekayo ekuphuculeni iimeko self-yolawulo.

Njengoko homeostasis - urhulumente esekelwe ukukhuthazana kunye nokusingqongileyo, iinkqubo enjalo ingaba iintlobo ezimbini ingxelo: akhabayo kunye navumelanayo. inkqubo uhlobo ingxelo okugwenxa kubonakaliswe indlela leyo etshintsha utshintsho njengeminqweno kwicala elahlukileyo. Impendulo inceda ukugcina imeko esisigxina kwinkqubo, ukunceda ukulungelelanisa ukuthotyelwa. Umzekelo uqhagamshelwano olunjalo ukukhonza thermoregulation ebantwini. Homeostasis - yinkqubo entsonkothileyo yentsebenziswano phakathi onke amacandelo enkqubo ngamnye. Ukwanda okanye ihliswe umzimba lobushushu thermoreceptors yobuchopho nesikhumba nangoko ukubhalisa tshintsho. Oku kwenyuka idluliselwe ingqondo, nto leyo ebangela ukuba impendulo isichasi umzimba - yandisa okanye ukuphakamisa iqondo lobushushu.

ingxelo entle ke zibonakaliswe kukwenyuka kwe variable. coupling enjalo ibangela ukusebenza destabilization, ngoko ungakuvumeli ukuba le nkqubo. Kuyinto azixhaphakanga apha ekusebenzeni kweenkqubo eziphilayo, kodwa une value yayo. Homeostasis - a inkqubo ofuna zidityaniswe zombini iindidi ingxelo. Umzekelo, zinciphisa isakhono yombane iiseli zemithambo sisizukulwana ngakumbi na intshukumo isakhono. Ngoko ke, i ingxelo eyakhayo kuyimfuneko ukutshintshela kwi kwimeko entsha homeostasis. Olo tshintsho kuthiwa metastable. Kwemizekelo yeenguqulelo ezinjalo inokuba ukwanda izondlo emilanjeni yamanzi ecacileyo, kukhokelela clouding kwechibi reaction kwakunye nezityalo imithana isiteshi yayo.

Homeostasis ecosystem - yohlobo olutshintshayo eziphilayo nendawo ngokusebenzisa ukuhlaziywa rhoqo lweziqalelo zalo ezisisiseko. Ingcamango kuvuselele endalweni sele eziveliswe yingcaphephe ngezityalo waseMerika eziphila Frederikom Klementsom. Ukongeza yentsalela ecosystem ezahlula eziphilayo, homeostasis yeselula kunye nokulungelelana emzimbeni womntu. Lo msebenzi kufuneka iqondwe luphawu jikelele iinkqubo ezininzi Ngokusebenza rhoqo kunye nabanye.
