Ingqikithi Yokuphila: Amanzi

Amanzi ayitshe lesisekelo sempilo, isinyibilikisi esibanzi esibalulekile kuzo zonke izinhlobo zokuphila ezaziwayo. Ukubaluleka kwawo kudlulela ngale kokufaka amanzi emzimbeni kuphela; ayisisekelo sezinqubo zezinto eziphilayo, ukusimama kwemvelo, ngisho nendawo yonke ebanzi.

Indima Yamanzi Ekuphileni

Emkhakheni wezinto eziphilayo, amanzi abalulekile. Akha ingxenye enkulu yomzimba womuntu—cishe ama-60%—futhi adlala indima ebalulekile emisebenzini eyahlukene yezemvelo. Kusukela ekulawuleni izinga lokushisa lomzimba ngokujuluka kuya ekwenzeni kube lula ukusabela kwamakhemikhali njengendlela yokwenza ama-enzyme, amanzi abalulekile ekugcineni i-homeostasis. Izinqubo zamaseli, okuhlanganisa ukuthuthwa kwezakhamzimba, ukususwa kwemfucuza, kanye nokwakheka kwamaprotheni ne-DNA, kuncike kakhulu emanzini.

Ukubaluleka Kwemvelo

Ngaphandle kwezinto eziphilayo ngazinye, amanzi abumba izimiso zemvelo kanye nesimo sezulu. Izinhlelo zamanzi ahlanzekile njengemifula, amachibi, kanye nezindawo ezimanzi zisekela izindawo zokuhlala ezahlukahlukene futhi zibalulekile ekusindeni kwezinhlobo eziningi. Amanzi nawo athonya amaphethini esimo sezulu kanye nokulawulwa kwesimo sezulu. Umjikelezo wamanzi, ohlanganisa ukuhwamuka, ukuminyana, imvula, kanye nokungena, usabalalisa amanzi kabusha emhlabeni wonke, ukuqinisekisa ukuthi izimiso zemvelo zithola umswakama odingekayo.

Ukuntuleka Kwamanzi Nezinselele

Naphezu kobuningi bawo, amanzi ahlanzekile ayimithombo engapheli. Ukuntuleka kwamanzi kuthinta izigidigidi zabantu emhlabeni wonke, okusongela impilo, ezolimo kanye nokuzinza komnotho. Izici ezifana nokushintsha kwesimo sezulu, ukungcola, kanye nokumbiwa ngokweqile kuqeda ukutholakala kwamanzi futhi kuphazamise imvelo. Ukubhekana nalezi zinselele kudinga imikhuba yokuphatha esimeme, imizamo yokulondoloza, kanye nokusungula izinto ezintsha kwezobuchwepheshe ukuqinisekisa ukufinyelela ngokulinganayo emanzini ahlanzekile.

Amanzi kanye neNdawo Yonke

Ukubaluleka kwamanzi kudlulela ngale koMhlaba. Ukusesha impilo yangaphandle komhlaba kuvame ukugxila ezindikimbeni zasezulwini ezinamanzi, njengoba ukuba khona kwawo kungabonisa ukuthi kungenzeka kube khona indawo yokuhlala. Kusukela kuMars kuya enyangeni ezibandayo zeJupiter neSaturn, ososayensi bahlola lezi zindawo ukuthola izimpawu zamanzi angcolile, angase asekele impilo ngale kweplanethi yethu.

Isiphetho

Amanzi angaphezulu nje kokuba yinto ebonakalayo; ayingqikithi yokuphila ngokwako. Ukuba khona kwawo kuwubufakazi bokuxhumana kwezinhlelo zezinto eziphilayo, izimiso zemvelo, ngisho nezenzakalo zasemkhathini. Njengoba sibhekana nobunzima bokuphathwa nokulondolozwa kwamanzi, kubalulekile ukuqaphela nokuhlonipha indima ebalulekile edlalwa amanzi ekusekeleni impilo nasekubumbeni umhlaba wethu.
