Iqhaza begazi amanzi. kungakhathaliseki ukuthi owokuphila kungenzeka ngaphandle kwamanzi

Amanzi - ke iyingxenye yezimpilo zethu. Izingxenye ezimbili kwezintathu surface eMhlabeni elalihlala izilwandle nasolwandle. Konke obusizungezile, lalingekho ngaphandle H ₂ O-molecule Ngisho nabantu nge amaphesenti angu-70 yakhiwa yalolu ketshezi. Iqhaza begazi amanzi kakhulu. Uzobona wena, uma ufunda lesi sihloko kuze kube sekupheleni.

Bheka ngefasitela. Ubonani? Abantu, izilwane, izitshalo, izindlu, izimoto. Nokho konke lokhu ephuma emanzini, iphesenti yayo ezahlukene zonke. Kungani uye kude? Ucabanga ukuthi koqweqwe lwawo izinyo namathambo kukhona amazing kakhulu-molecule H ₂ O? Yiqiniso, amaphesenti abo kuphela lincane kakhulu. Esikhathini sethu zobuchwepheshe ngaphandle abantu amanzi akakwazi ukukwenza.

I-molecule yamanzi

Lesi sihloko sizodingida property amanzi alo indima begazi. kakade Sithe umsebenzi yalolu ketshezi baningi kakhulu futhi ezihlukahlukene. Asikhulume kancane mayelana nendlela ukwakha i-molecule ke kuyacaca ukuthi kungani lokhu kwakwakhe kuyinto Amatebhe ngakho futhi jikelele. Asiqale kwengoma. I-molecule yamanzi iqukethe 3 ama-athomu: 2 - 1 kanye hydrogen - umoya-mpilo. Ume njengephini unxantathu isosceles. into enjalo kuyinto dipole ngoba polarity. Amanzi - kungcono uxhumano emangalisayo, njengoba kungaba ezintathu zithi:

• okuqinile;
• uketshezi;
• gaseous.

Iqhaza begazi amanzi kakhulu. manje Sizoqhubeka ukucabangela imisebenzi engqamuzaneni isimangaliso.

kuphela

Iqhaza begazi amanzi ukuthi angahlakaza kahle ezihlukahlukene izinto. Kodwa lena enye kwemisebenzi kulowo masipala. Njengoba kunjalo nganoma ikuphi izidakamizwa uyakwazi ukuncibilikisa emanzini, khona-ke Lihle ukuthola lolu ketshezi kuyinto cishe engenakwenzeka, kungenzeka ukuba kukhishwe kuphela ngaphansi kwezimo zelabhorathri. Noma yimuphi kuphela mbaxa kuphela inombolo ethile izinto. Ngakho, lapho ayegcwele izixazululo aqueous, isb uma kungekho kuphela abaningi chaza bese uthatha enye into. Kodwa uma amanzi ukufuthelana, ikhono lawo njengoba inyuka kuphela kakhulu. Ukuhlolwa: chaza umthamo ofanayo ushukela noma usawoti emanzini ashisayo nabandayo. Yiqiniso, kule nokonakala ashisayo kwenzeka ngokushesha okungaka, futhi kuyoba khona ikhekhe.

thermotaxis

Iqhaza begazi amanzi njengoba ikhono kulondolozwe izinga lokushisa emzimbeni njalo. Okusho ukuthi, lapho amakhaza eshubisa umnkantsha futhi endaweni efudumele lokushisa komzimba wethu (sicabangela ukuthi umuntu enempilo) izohlala ingashintshiwe - 36,6 degrees. Lokhu zingachazwa ngezinqubo yokuthi amanzi uyakwazi ukuthatha nokushisa kuphole kancane kakhulu.

Manje okuncane mayelana nokuthi lokho ukushisa. Lokhu exchange of ukushisa phakathi umzimba kanye nemvelo. Isici esiyinhloko - iyona lokushisa komzimba lesidalwa okuyinto sincike izinqubo umzimba kanye okukhipha ukushisa. Kukhona futhi izinhlobo ezimbili zezinkantolo izidalwa eplanethini yethu ophilayo:

• poikilothermic;
• homoiothermal.

We fanele kuze iqembu lesibili, okungukuthi, kukhona futhi esinegazi elifudumele. lokushisa wethu akusho ziyahlukahluka nezinguquko ezingeni lokushisa elifanele.

iseli kuyaqina

Manje ngalokho begazi indima yamanzi kuseli. Njengoba kushiwo ngaphambili, emanzini yiyona kuphela abahilelekile thermoregulation. Ngaphezu kwalokho osekushiwo, kuba isisekelo sokuthethelelwa organelles yamaseli begodu isekela ifomu yakhe elungile. Lokhu kungachazwa kanje: Amanzi kunzima kakhulu ukuba cindezela, ngisho endaweni yokucwaninga, kuyasiza silondoloze kuyaqina kwamaseli. Uma ungakholwa ukuthi kuye, bese uswayipha isipiliyoni: uzama ukumpintsha amanzi. Ngiyavuma, kunzima ngempela.

ukusebenza kwezithuthi

Esinye isici amanzi yikhono layo ukuletha izinto ezidingekayo. Manje sizogxila ukusebenza kwezithuthi. Amandla ukuletha izinto ezidingekayo kungenxa okusezingeni eliphezulu ebusweni ukungezwani ketshezi. Ngakho, amanzi ukungena kuma-capillary, isikhala intercellular. Okusho ukuthi, it has amaseli amandla ubonisa izinto ezingafuneki. Water has ezihlukahlukene izakhiwo, okungukuthi banayo ukuba ngibonge ukukhishwa yonke imisebenzi ebalulekile.

indima emvelweni

Sesihlole yini indima begazi amanzi, kodwa kubalulekile ukuba baqonde iqiniso lokuthi indima emvelweni ke kubaluleke. Asikwazi ukuhlukanisa izici ezimbili:

• Isici zangaphandle kwemvelo;
• isici sangaphakathi kwemvelo.

iziphi izici zangaphandle zibandakanya inombolo izici, ezifana sezulu, isimo sezulu, ukukhahlamezeka kwendawo, nokunye. umthelela Domestic ngokuyinhloko amaseli yezinto eziphilayo. Ngakho, umuntu angabona ukukhomba inombolo yezici futhi izinqubo lapho amanzi lihilelekile. Eziningi zalezi imisebenzi ebalulekile abantu.
