Isingeniso: Imfihlakalo Yejubane LePenguin
Amaphengwini aziwa kakhulu ngekhono lawo lokubhukuda ngokushesha emanzini. Zingafinyelela isivinini esingafika kumakhilomitha angu-22 ngehora, okuzenza zibe enye yezinyoni ezibhukudayo ezishesha kakhulu emhlabeni. Kodwa yini eyenza amaphengwini asheshe futhi asebenze kahle emanzini? Lo mbuzo uye wadida ososayensi nabacwaningi iminyaka eminingi.
Izici Zomzimba zamaPenguin
Ama-penguin ajwayele ukujwayela ukuphila ezindaweni ezinokhahlo nezibandayo ezifundeni ze-Antarctic kanye ne-sub-Antarctic. Zinomzimba oqondile, ozisiza ukuthi zikwazi ukutshuza emanzini ngokumelana okuncane. Amaphiko azo ashintshile aba izimpiko, ezizisebenzisayo ukuze ziziqhube emanzini. Amaphengwini nawo ambozwe ungqimba lwezimpaphe eziwugqinsi, ezivikelayo, eziwagcina efudumele emanzini abandayo.
Ukubaluleka Kwejubane Kumaphengwini
Ijubane libalulekile kumaphengwini, njengoba ethembele emandleni awo okubhukuda ukuze abambe izinhlanzi nezinye izilwane. Ukubhukuda ngokushesha futhi kuzisiza ukuba zibaleke ezilwaneni ezidla ezinye, njengezimvu zamanzi nama-orcas. Kumaphengwini ahlala emakoloni, isivinini sibalulekile futhi ekuhambeni emanzini aminyene nokugwema ukungqubuzana nezinye izinyoni.
Isayensi yePenguin's Hydrodynamics
Amaphengwini anesitayela sokubhukuda esiyingqayizivele esisebenza kahle kakhulu. Basebenzisa amapheshana abo ukuze benze ukusunduza okunamandla, okubaqhubezela phambili emanzini. Umumo wazo ohlelekile wehlisa ukudonsa kanye nesiyaluyalu, uzivumela ukuthi zihambe ngokushesha emanzini ngokumelana okuncane.
Indlela Amaphengwini Asebenzisa Ngayo Amaphiko Awo Ukuze Abhukude
Amaphengwini asebenzisa amaphiko awo "ukundiza" emanzini. Babhakuzisa amaphiko abo phezulu naphansi, okwenza ukusunduza okunamandla okubaqhubezela phambili. Amaphengwini angakwazi futhi ukusebenzisa iziphepho zawo ukuqondisa, okuwavumela ukuthi ajike ngokushesha futhi aqondise.
Iqhaza Lezimpaphe Ekuthuthukiseni Isivinini
Amaphengwini ambozwe ungqimba lwezimpaphe eziminyene, ezingangenwa amanzi ezisiza ukuzigcina zifudumele futhi zomile emanzini. Lezi zimpaphe nazo zidlala indima ebalulekile ekuthuthukiseni amakhono azo okubhukuda. Izimpaphe zihlelwe ngendlela enciphisa ukudonsa kanye nesiyaluyalu, okuvumela amaphengwini ukuba ahambe emanzini ngesivinini esikhulu nangempumelelo.
Imisipha Eyisipesheli kumaPenguin
Amaphengwini anemisipha yokubhukuda eyisipesheli ethuthuke kakhulu. Le misipha itholakala esifubeni futhi inesibopho sokunika amandla ama-flippers. Imisipha inamandla kangangokuthi ingakwazi ukukhiqiza amandla anele ukuqhubeza amaphengwini emanzini ngesivinini esikhulu.
Imfihlo Yesimo Esilula SePenguin
Amaphengwini anomumo womzimba ohlelekile olungele ukubhukuda. Ukwakheka kwemizimba yazo kunciphisa ukudonsa kanye nesiyaluyalu, kuzivumela ukuthi zikwazi ukuhamba emanzini ngokumelana okuncane. Ukuma koqhwaku nekhanda labo nakho kuyasiza ekunciphiseni ukudonsa nokuthuthukisa i-hydrodynamics yabo.
Umthelela Wezinga Lokushisa Lamanzi Ejubaneni LePenguin
Izinga lokushisa lamanzi lingaba nomthelela omkhulu emakhonweni okubhukuda ophengwini. Emanzini abandayo, amaphengwini ajwayele ukubhukuda ngokushesha nangempumelelo. Lokhu kungenxa yokuthi amanzi abandayo aminyene kakhulu, okwenza izinyoni zikwazi ukumelana nokuvuvukala.
Ukuqhathanisa Nezinye Izinyoni Zasemanzini
Amaphengwini ahlukile ezinyonini zasemanzini ngamakhono awo okubhukuda. Babhukuda abasheshayo futhi abanekhono kakhulu kunezinye izinyoni eziningi, kuhlanganise nezinye izinyoni zasolwandle njengama-gull nama-pelicans. Amaphengwini aphinde abe nesimo somzimba esilula kanye nemisipha ekhethekile yokubhukuda.
Inzuzo Yokuziphendukela Kwemvelo Yokubhukuda Ngokushesha
Ukubhukuda okusheshayo kube wushintsho olubalulekile kumaphengwini eminyakeni eyizigidi zokuziphendukela kwemvelo. Ibavumele ukuthi baphile futhi bachume endaweni enzima nencintisanayo yezifunda ze-Antarctic kanye ne-sub-Antarctic. Ukubhukuda okusheshayo kuphinde kwasiza ama-penguin ukuthi aguquke abe yizinhlobonhlobo zezinhlobo zezilwane, ngayinye inezindlela zayo ezihlukile ukuze ziphile.
Isiphetho: Umhlaba Othakazelisayo Wamaphengwini
Ama-penguin ayizidalwa ezihehayo ezithathe imicabango yabantu emhlabeni jikelele. Ikhono labo lokubhukuda ngesivinini esiphezulu kungenye yezinto eziningi ezizijwayeza ezizenza zihluke futhi ziphawuleke. Ngokufunda isayensi ye-penguin's hydrodynamics, singathola ukuqonda okwengeziwe ngalezi zinyoni ezimangalisayo kanye nezindawo ezihlala kuzo.
