Namuhla siza ukuphawula ngohlobo olwehlukile ezinhlanzini esizijwayele. Akuyona inhlanzi esizobhekana nayo, kepha izipanji zasolwandle. Kuyinto isilwane esingenamgogodla elisonqenqemeni lwe i-porifera. Bahlala kuphela izindawo zasemanzini futhi ungethuli noma yiluphi uhlobo lokunyakaza okusebenzayo. Njengoba igama layo libonisa, akuyona into engaphezu kwesipontshi, kodwa uyaphila. Iphakathi kwezilwane ezilula kakhulu ochungechungeni lokuziphendukela kwemvelo, kusukela abanazo izicubu zangempela.
Uyafuna ukwazi konke mayelana nezipontshi zasolwandle? Uma uqhubeka ufunda, uzothola curioso ziyini lezi zilwane?
Izici eziyinhloko
Njengoba sishilo ngaphambili, izipanji zasolwandle yizilwane ezilula kakhulu. Lezi yizilwane ukuthi Abavezi ukulinganisa okuchaziweImizimba yazo ayinawo umumo ongashintshi, nakuba ezinye izinhlobo zinawo i-radial symmetryIsici esibaluleke kakhulu, futhi esinikeza igama ku-porifera phylum, ukuthi imizimba yakhiwe inethiwekhi yezimbotshana, imigudu namakamelo amanzi adlula ngawo futhi, ngale ndlela, bayazuza ukudla y umoya-mpilo.
Njengoba zingenazo izicubu ezikhethekile, izipontshi zasolwandle zinenani elikhulu amaseli we-totipotentLawa maseli ayakwazi ukuguqukela kunoma yiluphi uhlobo lweseli isilwane esilidingayo ngesikhathi esithile. Leli khono libenza ngokwedlulele kuyahlukahluka futhi nge amandla amakhulu okuvuselela, ngisho nalapho ukulahlekelwa okukhulu kwesisindo somzimba kwenzeka.
Nakuba ukuma kwezipontshi zezinhlobo ezahlukene kungahluka kakhulu, zonke zinesakhiwo esifanayo. Wonke anembobo enkulu phezulu emzimbeni wawo owaziwa ngokuthi qabula. Kungale mbobo lapho kuphuma khona amanzi azungeza ngaphakathi kwezipontshi. Izindonga zemizimba yazo zigcwele izimbotshana ezinobukhulu obuhlukahlukene. Kungalezi zimbotshana ukuthi kungena amanzi futhi ukuvuza kwenzeka.
Uhlobo lweseli oluhlukile kuzipanji zasolwandle Lawa angama-choanocyte. Leli seli likhethekile ekuhlungeni. Ukuhlunga kuyinqubo isipontshi esithola ngayo ukudla. Amaseli ane-a i-flagellum kanye nama-microvilli amaningana ayizungezile futhi yiwo abangela imisinga yamanzi amancane lapho amanzi engena ngawo esipontshini.
I-anatomy eyisisekelo: izendlalelo nohlaka lwamathambo
Umzimba wesipontshi uhlelwe waba izingxenye ezintathu eziyinhloko: isembozo sangaphandle esibizwa ngokuthi iphinikhodi, ungqimba lwangaphakathi olufakwe ama-choanocyte okuthiwa i-choanoderm futhi, phakathi kwabo, i-gelatinous matrix ebizwa ngokuthi mesohylKu-mesohyl kutholakala i-collagen fibers (isiponji), ama-spicule amaminerali namaseli ahambayo enza imisebenzi ye ukugaya, ezokuthutha kanye nokuzivikela.
I-Las ama-spicule kungaba silica noma of i-calcium carbonate futhi ziza ngamajamo nobukhulu obuhlukahlukene (kusuka i-megascleras a ama-microscleras). Ukuhlanganiswa kwayo nesiponji kunquma ukuthi uhlaka lwamathambo lungaphezulu yini nezimo noma ngaphezulu iqine, futhi inomthelela ekuvikelekeni ezilwaneni ezidla ezinye.
Izinhlobo zenhlangano yesistimu ye-aquifer
Ukuze kuthuthukiswe ukuhlunga kwazo, izipontshi ziye zashintsha izinhlelo ezintathu zenhlangano zangaphakathi ezikhulisa i- indawo yokuhlunga ukwakheka kwe-choanoderm:
- I-Asconoid: i-tubular, ene-cavity ephakathi nendawo (spongocele) efakwe ama-choanocyte.
- I-Syconoid: udonga olujiyile futhi olugoqiwe iziteshi zama-radial enamakamelo ahlotshisiwe.
- i-leukonoid: eyinkimbinkimbi kakhulu, eneziningi amagumbi anyakazayo okuxhumene nokuqabula okuningana.
Izinhlobo zamaseli eziyinhloko
- ama-pinacocyte: Zimboza ingaphandle futhi zibe negalelo ekuvikeleni nasekulawuleni ukugeleza.
- ama-porocyte: amangqamuzana amise okweshubhu akha izimbotshana ezihogelayo (akhona ikakhulukazi ezipontshini ezine-calcareous).
- ama-choanocyte: amaseli ane-flagellum nekholomu ye-microvilli leyo khiqiza okwamanje y phagocytize izinhlayiya.
- Ama-archaeocyte noma ama-amoebocyte: i-totipotent; iqhaza ukugaya, ukuthutha, ukukhipha y ukuvuselelwa.
- ama-sclerocyte: khiqiza i ama-spicule yamathambo.
- ama-spongiocyte: bayafihla isiponji (collagen) eqinisa uhlaka.
- ama-myocyte: amaseli isivumelwano ezilawula ububanzi be-pores kanye ne-oscula.
I-physiology ebalulekile
Izipontshi azikho uhlelo lwezinzwa, uhlelo lokugaya ukudla y izitho zomzimba ngesitayela sezinye izilwane. Ukudla okunomsoco kusekelwe ukugaya kwe-intracellular (phagocytosis kanye ne-pinocytosis), ukushintshaniswa kwegesi kanye nokukhipha igesi kwenziwa ngu ukusakaza, kanye nokuxhumana kwezimpendulo (ukuvulwa noma ukuvala ama-pores) kufinyelelwa ngamasignali amakhemikhali nokufinyela kwamaselula.
Ukuhlukaniswa kwe-Taxonomic (isifinyezo esiwusizo)
Umphetho I-Porifera Ihlanganisa amakilasi amane amakhulu amukelwa izincwadi ezikhethekile: I-Calcarea (ama-calcareous spicules), I-Hexactinellida (izipontshi zengilazi ezinama-spicules siliceous kanye nenhlangano ye-syncytial), demospongiae (izinhlobo eziningi, ezine-spongin kanye/noma ama-siliceous spicules) kanye I-Homoscleromorpha (iqembu elinezici eziyingqayizivele ze-epithelium yalo). Lokhu kwehlukahlukana kwesakhiwo kuchaza yayo ukujwayela okubanzi ezindaweni ezahlukene.
Ibanga nendawo yokuhlala
Nakuba izipontshi zasolwandle ziyizilwane ezingenamgogodla, ziyakwazi shintsha ezimeni ezahlukene. Ebhekene nezimo ezimelene nezilwane obekungenakwenzeka ukuzinqoba noma ukusinda, uba ngumsindisi weqiniso. Bayakwazi ukubekezelela ukungcoliswa kwamanzi ngama-hydrocarbon kahle, izinsimbi noma ezinye izinto eziyingozi.
Zinezilwane ezidla ezinye zemvelo ezimbalwa ngenxa yazo uhlaka lwama-spicules futhi kukhulu ubuthiLokhu kwenza isipontshi sasolwandle singene ngaphakathi zonke izilwandle nezilwandle Izindawo ezidume kakhulu zezipontshi eziningi ezavunwa ekhulwini lama-20 cishe yiMpumalanga Mediterranean, iGulf of Mexico, iCaribbean, nezilwandle ezizungeze iJapane.
Ngokuqondene nendawo yokuhlala, iyisilwane esingenamgogodla sesile. Lokhu kusho ukuthi bayaphila kulungisiwe olwandle futhi unganyakazi. Bayakwazi ukuhlala ekujuleni okukhulu, nakuba zingatholakala nasezindaweni ezikha phezulu kakhulu. Iningi labo likhetha izindawo lapho i- ukukhanya kwelanga alinamandla kakhulu.
Ukujula, i-substrate namanzi aphakathi nezwe
Izipontshi eziningi ziyachuma phakathi amanzi ahlanzekile futhi azolile, njengoba ukungcola okweqile kungavala izimbotshana. Balungiselwe ama-substrates aqinile (idwala, amagobolondo, amakhorali) kanye nezinye izinhlobo zezilwane ziye zakha izisekelo ngendlela ye izimpande ukunamathela ezinhlangeni ezithambile. Nakuba iningi lingasolwandle, kunezinhlobo ezimbalwa zezinhlobo amanzi amasha ehlala emifuleni nasemachibini.
Izimo ezengeziwe
Ezindaweni ezinamagagasi, izinhlobo ezithile zivala izimbotshana zazo vimbela ukomisa lapho bevezwa. Ngaphezu kwalokho, nakuba ziyi-sessile, ezinye izipontshi zibhalwe phansi ukunyakaza kancane kakhulu ku-substrate (ngokuhleleka kwamamilimitha ngosuku) ngokukhula okuhlukile nokufinyela kwezicubu.
Ukondla izipanji zasolwandle
Ukudla okuyinhloko kwalezi zilwane izinhlayiya eziphilayo izinhlayiya ezincane kakhulu ezitholakala olwandle ezikwazi ukuhlunga ngezimbotshana zazo. Nokho, Bangakwazi ukudla ama-plankton nama-bacteria yezilinganiso ezincane. Ezinye izipontshi ziyakwazi ukumisa a i-symbiosis ngamabhaktheriya noma ezinye izinto eziphilayo ezi-unicellular. Lobu budlelwano bubanikeza izinzuzo ezinjengokufinyelela ezintweni eziphilayo.
Kunezilwane olwandle ongase ube nazo ubudlelwano bokusebenzisanaLolu hlobo lobudlelwano lusho ukuthi bobabili abathintekayo bayazuza komunye nomunye. Lobu budlelwano buhilela izilwane ezingenamgogodla noma izinhlanzi ezisebenzisa izipontshi zasolwandle njengendawo yokucasha kwezinye izilwane ezidla ezinye ezinkulu. Izilwane ezithile ezingenamgogodla zingazishumeka kuzo futhi zizisize zinyakaze ngenkathi zizifihla. Lesi yisibonelo esicacile sobudlelwane obuhlangene.
Ukuhlunga okusebenzayo nodaba oluncibilikisiwe
Isihlungi sezipontshi amanzi amaningi nsuku zonke. Sibonga ukushaya okudidiyelwe kwe ama-choanocyte, bamba amagciwane, ama-microalgae kanye izinto eziphilayo ezincibilikisiwe ezinye izinto eziphilayo ezingakwazi ukuzisebenzisa. Ezinye izinhlobo zingakwazi ukucubungula amashumi amalitha nsuku zonke, ezenza okwangempela abahlanzayo yendawo yokuhlala.
Izipontshi ezidla inyama
Ezindaweni ezimpofu ezinhlayiyeni ezimisiwe (isibonelo, imigede noma ukujula kwalasha), amaqembu athile afana Cladorhizidae balahlekelwe isistimu ye-aquifer ejwayelekile futhi bathuthuke ama-spicule ahlanganisiwe ukubamba okuncane crustaceansLe ndlela yokuphila ibonisa ukungavamile kwayo ipulasitiki yemvelo.
Ama-symbionts e-photosynthetic
Izipontshi eziningi zibamba i-photosynthetic microorganisms (i-cyanobacteria, i-zooxanthellae, i-diatoms) ebahlinzeka ngemikhiqizo ye-photosynthesis. Kwezinye izimo, ama-symbionts angamela a isilinganiso esimangalisayo umthamo womzimba. Baxosha ngezikhathi ezithile ama-symbionts kanye amafinyila ukuze uvuselele i-microbiome yakho futhi uhlanze izindawo zakho.
Ukuzala
Uma ziyizinto eziphilayo ezingashukumi futhi zingahambisani, zikhiqiza kanjani? Ngemuva kwalokho Bangakwazi ukuzala kokubili ngokobulili nangokocansi. Esokuqala sibonga amaseli e-totipotent esiwabone ngaphambili. Kubenza baguquke babe amaseli alungele ukuzala. Izinhlobo ezimbili ezijwayelekile zokukhiqizwa kwe-asexual yilezi ihlumelaEzinye izinhlobo zamanzi ahlanzekile zingakwenza lokhu gemulation.
Ngenxa yokuthi izipontshi azinazo izitho ezithile ezikhethekile zanoma yimuphi umsebenzi, futhi azinazo izitho zobulili. Lokhu kungaba inkinga ekukhiqizeni kabusha. Nokho, iningi labantu linjalo ama-hermaphrodites. Badinga a cross-fertilization ukukhiqiza kabusha ngendlela efanele. Kokubili isidoda namaqanda kuvela kuma-choanocyte. Lezi zikhishelwa ngaphandle, futhi kulapho ukuhlangana phakathi kwamaseli amabili kwenzeka. Ngakho-ke, sikhuluma ngokukhulelwa kwangaphandle.
Ukuthuthukiswa kwezipontshi kuyinto engaqondileNgemva kokukhula kwabo, badlula ezigabeni izibungu ngaphambi kokukhula ube umuntu omdala. Izinhlobo ezine ezahlukene zezibungu ziyaziwa, kuye ngezinhlobo zezilwane.
Amamodi nezigaba ngemininingwane eyengeziwe
Ngaphezu kwe izingcezu (ikhono lokukhiqiza kabusha abantu abaphelele ngezicucu), emanzini ahlanzekile amagugu Zisebenza njengezakhiwo zokumelana nezimo ezimbi. Ekuzalweni kocansi, ezinye izinhlobo zikhipha ama-gametes emanzini, kanti kwezinye i isidoda faka i-aquifer system yomunye umuntu futhi ithwalwe ama-phorocyte kuze kufinyelele ama-ovulesPhakathi kwezinhlobo zezibungu ezichazwe, okulandelayo kuvelele: i-parenchymula, i-celloblastula, stomoblastula y i-amphiblastula, konke kwe impilo yamahhala ngaphambi kokuqedwa kokugcina.
Izintshisakalo zezipanji zasolwandle
Nakuba zingacatshangelwa, izipantshi zasolwandle zihlanganisa ezinye izinto ezinobuthi noma ama-antibiotic ukugcina izilwane ezidla ezinye zikude. Eziningi zalezi zinto zisetshenziswa emithini imboni yezokwelapha kanye nezakhiwo abanazo zisetshenziselwa ukulwa nezifo ezivame kakhulu emphakathini wethu.
Kuyaziwa futhi ukuthi babe nobudlelwano nabantu ngenxa yokuba wusizo kwabo njenge ithuluzi lokuhlanzeka komuntu siqu. Njengamanje, ukuthengwa nokuthengiswa kwezipanji ukuze zisetshenziselwe umuntu kulawulwa kakhulu ngenxa yomonakalo owenzeka kubantu babo.
Idatha emangazayo eyengeziwe
- Ama-genomes amangalisayo: Naphezu kokuba lula kwazo, izipontshi eziningi zinezakhi zofuzo ezingamashumi ezinkulungwane ukufana ezindleleni zamaselula ezitholakala ezilwaneni ezinomgogodla.
- Izakhi zofuzo ezabelwa abantu: Kuhlonzwe izakhi zofuzo ezihambisana nalabo abathintekayo i-synapse y ukufinyela kwemisipha, esiza ukuphenya imvelaphi yemisebenzi eyinkimbinkimbi yamaselula.
- Izihluthulelo zokulwa nezifo: ingxenye yofuzo lwabo kanye ama-metabolites Okwesibili kufundwa njengezinkomba zokuqonda ukwanda kwamaseli futhi uthole ama-compounds i-antitumor y elwa namagciwane.
- Abasindile abazalwa: bamelene iziqephu zokushintsha kwemvelo kuwo wonke umlando weplanethi futhi ikoloni kusuka ezishisayo a polar.
- Ukuphila isikhathi eside okumangalisayo: ezinye izinhlobo zingafinyelela ukuguga kakhulu ngenxa yemetabolism ehamba kancane namandla okuvuselela.
- I-locomotion ecashile: nakuba i-sessile, abanye bangakwazi hamba kancane (amamilimitha ngosuku) elungisa umumo wayo namaphoyinti okuhanjwa kuwo.
- Ukusetshenziswa kwamathuluzi ezilwaneni zasolwandle: kubhaliwe amahlengethwa abasebenzisa izipontshi njengesivikelo samakhala abo lapho befuna ukudla okungaphansi kwesihlabathi.
Ukuvikelwa kwemvelo kanye nobudlelwano
Zimbalwa izilwane ezidla izipontshi ngenxa yazo ubuthi kanye nohlaka lwama-spicules. Phakathi kwezilwane ezizingelayo ezikhethekile kukhona ezinye opisthobranch, ezithile inhlanzi y echinoderms. Ngakolunye uhlangothi, izilwane eziningi ezingenamgogodla nezinhlanzi zisizakala ngakho imigodi njengesiphephelo, futhi izinkalankala Bangakwazi ukuthwala izipontshi emagobolondweni abo ukuze ukufihla, enikeza ukuhamba kwayo “kubagibeli”.
Izinsizakalo ze-ecosystem
Okushubile umthamo wokuhlunga izipontshi kusiza ukugcina amanzi acwebile isivele igaywe kabusha izakhamzimbaEziweni, zishintsha izinto eziphilayo ezincibilikisiwe zibe izinhlayiya ukufinyeleleka kwezinye izinto eziphilayo, ukusekela amaketanga okudla. Ngakho-ke, izinzuzo zabo zokongiwa kwemvelo ezokudoba futhi i ukwehluka ama-benthos.
Ukuvuna: Izipontshi zasolwandle ngokuvamile evunwa ngabatshuzi Besebenzisa izinto ezikhethekile ezinjengamanetha, imimese, noma izikele, abatshuzi bakhetha ngokucophelela izipontshi ezisuka phansi olwandle, baqinisekise imikhuba yokuvuna eqhubekayo ukuze kulondolozwe izipontshi kanye nemvelo yasolwandle.
Ukuhlanza nokucubungula: Uma seziqoqiwe, izipontshi zasolwandle ziyahlanzwa ukuze kukhishwe noma iyiphi imfucumfucu, izinto eziphilayo, noma inzika okungenzeka inamathela kuzo. Le nqubo ngokuvamile ihilela ukugeza izipontshi emanzini olwandle noma emanzini ahlanzekile futhi uzihlikihle ukuze ususe ukungcola.
Ukomisa: Ngemva kokuhlanza, izipontshi zasolwandle ziyekwa ukuze zome elangeni noma endaweni enomoya omuhle. Ukomisa kusiza ukususa umswakama owedlulele futhi kuvimbela ukukhula kwesikhunta noma amagciwane.
Nquma futhi umumo: Kuye ngokusetshenziswa okuhlosiwe, izipontshi zasolwandle zingasikwa futhi zibunjwe ngobukhulu obufunayo nokuma, ngesandla, kusetshenziswa isikelo.
Guqula umbala onsundu wemvelo ube ophuzi: Amanye amakhasimende akhetha izipontshi eziphuzi, ezitholwa kusetshenziswa indlela yendabuko efanayo esetshenziswa eGreece amakhulu eminyaka, kusetshenziswa izinto zasendlini ezindala ezifana nomcako.
Izipontshi zasolwandle, ngokuxakile, ziyizilwane ezingenamgogodla. Abanye ososayensi bathi baphakathi kwezilwane ezindala kunazo zonke eMhlabeni, ezivelayo cishe iminyaka eyizigidi ezingama-640.
Afakwe kukhathalogi cishe 9000 izinhlobo zezipontshi, ezinezinhlobonhlobo zokwakheka nemibala. Naphezu kwakho konke lokhu kuhlukahluka, ukwakheka kwabo kufana kakhulu.
Ziyizilwane elula, abanazo izitho ezithile futhi imizimba yabo yakhiwe ngezimbotshana nemigudu amanzi azungeza ngayo, okubavumela ukuba bathole ukudla nomoya-mpilo, bathuthe imfucuza namangqamuzana okuzala.
Isici esibaluleke kakhulu sezipontshi zasolwandle amandla azo amakhulu ukuvuselelwa ngisho nalapho belahlekelwa inqwaba yesisindo somzimba wabo. Ngokwesibonelo, uma isipontshi sichotshozwa, ingxenye ngayinye iyakwazi ukwenza isipontshi esisha.
Isipontshi ukuphela kwesilwane esaziwayo esinale ndlela engavamile yokuzivuselela.
Zihlala ngaphansi kolwandle futhi zingakwenza lokho ekujuleni okukhulu nasezilwandle ezingashoni kakhulu.
Ningatholana cishe kuzo zonke izilwandle, njengoba bekwazi ukuzivumelanisa kahle nezimo ezihluke kakhulu. Nokho, izindawo ezinezipontshi eziningi kakhulu yilezi I-Eastern Mediterranean, iCaribbean, iGulf of Mexico kanye neJapan.
Umlando omncane mayelana nokusetshenziswa kwezipontshi zasolwandle
Kukholakala ukuthi abaseGibhithe Babengabokuqala ukusebenzisa izipontshi zasolwandle, futhi uCleopatra wazisebenzisa ukugeza nokumunca ukugeleza kokuya esikhathini. Uma ufuna ukufunda okwengeziwe ngokusebenzisa izipontshi njengama-tampons wokuya esikhathini, chofoza lapha.
Abantu baseMedithera baye basebenzisa izipontshi ngezindlela eziningi. Ngaphezu kwenhlanzeko yomuntu siqu, amaRoma ayewasebenzisela ukuphuza amanzi phakathi nemikhankaso yawo yezempi, njengoba esinye sezici zesipontshi siwukuba simunca uketshezi ngaphandle kokuluvumela ukuba luconse. Babesebenzisa nezipontshi ukuze bavikele imizimba yabo ezimbathweni zempi. Elinye iqiniso elithakazelisayo ukuthi esinye sezenzakalo zeMidlalo Yama-Olympic eRoma lasendulo kwakuyi- ukudoba isipontshi.
Izipontshi zasolwandle zemvelo sekuyisikhathi eside ziyisisekelo sasekhaya, kokubili ekuhlanzeni indlu okuvamile kanye nokunakekelwa komuntu siqu. Ukusetshenziswa kwabo kwathinteka kakhulu ngokubukeka kwe izipontshi zokwenziwa okwabashintsha ngokoqobo. Namuhla, sizithola sisenkathini yokuvuselelwa kwemikhiqizo yemvelo neqhubekayo, ebaluleke kakhulu ekugcineni ibhalansi yomhlaba.
Uhwebo lwendabuko noluzinzile
Ezinhlotsheni ezingenakubalwa zezipontshi ezikhona, ezinhlanu kuphela ezibhekwa njengezingathengiswa. Zonke izipontshi ezithengiswa kuleli khasi, ezizalelwa endaweni yaseMedithera - eGreece, ziyizipantshi ezisezingeni eliphezulu nezithambile kakhulu emhlabeni. Ziye zatshalwa futhi zavunwa ngokulandela izindlela zemvelo zendabuko, ezikude nokuhlasela kwezinhlobo, ezithanda ukukhula nokuvuselelwa kwazo. Lokhu kungenxa yokuthi abatshuzi baqoqa izipontshi beshiya isisekelo sazo (izimpande) siphelele futhi, ngaphezu kwalokho, bagcina izipontshi emanetheni olwandle phakathi nesikhathi sokubanjwa nokunyakaza kwezikebhe, bethanda futhi bekhuthaza ukuzala kwazo ngokwemvelo. Ukuthunjwa kwezipontshi zemvelo kuwukuhweba okwenziwa amakhulu eminyaka, okudluliswa kusuka kubaba kuya endodaneni futhi okuye kwanakekela ngokukhethekile ukugcinwa nokuvuselelwa kwalo mkhiqizo wemvelo. Izizathu ezi-5 zokusebenzisa isipontshi sasolwandle esikhundleni sesokwenziwa
Ngaphandle kokungabaza, ukukhetha isipontshi semvelo kuyinketho yokuwina yawo wonke umuntu ohilelekile:
umuntu, ngokusebenzisa umkhiqizo ongenabuthi ongenawo umphumela olimazayo emzimbeni wakho;
abakhiqizi abancane kanye nabo bonke abathintekayo ekuqoqweni kwezipontshi, ngokuqhubeka nomthombo wabo wemali engenayo kanye nokugcina lokhu kuhwebelana kwendabuko kuphila;
imvelo, ngokususa inani elikhulu lemfucuza engaphinde isetshenziswe kanye nakho konke ukuthuthukiswa kwezimboni okuhlanganisa imikhiqizo yokwenziwa;
izipontshi zasolwandle ngokwazo, ezivuselelwayo futhi zandise ukukhula kwazo ngokuvunwa kwazo.
Ithebula elingezansi libonisa izici ezi-5 ezihlukanisa izipontshi zasolwandle kunezokwenziwa.
Ngalo lonke lolu lwazi... Isiphi isipontshi osikhethayo sokunakekela nokuhlanza umzimba wakho nomndeni wakho? Vakashela isitolo sethu ukuze ufunde ngazo zonke izinhlobo zezipontshi zasolwandle zemvelo esiziphethe kanye nokusetshenziswa kwazo okuhlukile.
Izipontshi zasolwandle zikhona izilwane ezilula nezingavamile ngesikhathi esifanayo: bahlunga futhi bahlanze ulwandle, impilo ephethe, bakhiqize izinhlanganisela ezinamandla okwelapha futhi bahambisane nesintu imithombo yemvelo. Yazi ibhayoloji yakho futhi usekele eyakho ukusetshenziswa okuzinzile kuyisihluthulelo sokulondoloza indima yayo ebalulekile ezimisweni zemvelo zasolwandle.
