Tento zd\u00e1nliv\u011b jednoduch\u00fd \u00fakon je ve skute\u010dnosti pom\u011brn\u011b slo\u017eit\u00fd a zahrnuje jemnou rovnov\u00e1hu fyziky a fyziologie.<\/p>\n\n
Kdy\u017e ko\u010dka pije, ohne sv\u016fj jazyk dozadu do tvaru \u201eJ\u201c a dotkne se \u0161pi\u010dkou jazyka hladiny vody. Pot\u00e9 rychle st\u00e1hne sv\u016fj jazyk a vyt\u00e1hne sloupec vody do tlamy. Tento sloupec vody je pot\u00e9 zachycen uvnit\u0159 ko\u010di\u010d\u00ed tlamy a spolknut.<\/p>\n\n
Kl\u00ed\u010dem k tomuto procesu je ko\u010di\u010d\u00ed jazyk. Ko\u010di\u010d\u00ed jazyk je pokryt\u00fd drobn\u00fdmi ostny, kter\u00e9 pom\u00e1haj\u00ed vod\u011b p\u0159ilnout k jazyku. To umo\u017e\u0148uje ko\u010dce nabrat sloupec vody, i kdy\u017e se voda nedot\u00fdk\u00e1 stran jej\u00ed tlamy.<\/p>\n\n
Ko\u010di\u010d\u00ed jazyk m\u00e1 tak\u00e9 speci\u00e1ln\u00ed dr\u00e1\u017eku, kter\u00e1 vede st\u0159edem jazyka. Tato dr\u00e1\u017eka pom\u00e1h\u00e1 nasm\u011brovat vodu do ko\u010di\u010d\u00ed tlamy.<\/p>\n\n
Fyzik\u00e1ln\u00ed str\u00e1nka ko\u010di\u010d\u00edho lap\u00e1n\u00ed je tak\u00e9 velmi zaj\u00edmav\u00e1. Kdy\u017e ko\u010dka vyt\u00e1hne sv\u016fj jazyk z vody, sloupec vody je vystaven dv\u011bma sil\u00e1m: setrva\u010dnosti a gravitaci. Setrva\u010dnost je tendence objektu pokra\u010dovat v pohybu stejn\u00fdm sm\u011brem. Gravitace je s\u00edla, kter\u00e1 p\u0159itahuje objekty k zemi.<\/p>\n\n
Aby zabr\u00e1nila roztr\u017een\u00ed sloupce vody, mus\u00ed ko\u010dka st\u00e1hnout sv\u016fj jazyk rychlost\u00ed, kter\u00e1 je vy\u0161\u0161\u00ed ne\u017e rychlost gravitace. To je d\u016fvod, pro\u010d ko\u010dky lapou vodu tak rychle.<\/p>\n\n
Schopnost lapat vodu je pro ko\u010dky v\u00fdznamnou evolu\u010dn\u00ed v\u00fdhodou. Umo\u017e\u0148uje jim p\u00edt i z t\u011bch nejmen\u0161\u00edch zdroj\u016f vody a pom\u00e1h\u00e1 jim tak\u00e9 vyh\u00fdbat se pred\u00e1tor\u016fm. Ko\u010dky, kter\u00e9 jsou schopny lapat vodu rychle a efektivn\u011b, maj\u00ed v\u011bt\u0161\u00ed pravd\u011bpodobnost p\u0159e\u017eit\u00ed a rozmno\u017eov\u00e1n\u00ed.<\/p>\n\n
Existuje n\u011bkolik v\u011bc\u00ed, kter\u00e9 m\u016f\u017eete ud\u011blat, abyste pomohli sv\u00e9 ko\u010dce p\u00edt v\u00edce vody. Zaprv\u00e9 se ujist\u011bte, \u017ee m\u00e1 va\u0161e ko\u010dka neust\u00e1l\u00fd p\u0159\u00edstup k \u010derstv\u00e9 vod\u011b. Misky s vodou byste m\u011bli um\u00edstit tak\u00e9 na r\u016fzn\u00e1 m\u00edsta v dom\u011b, aby va\u0161e ko\u010dka v\u017edy na\u0161la m\u00edsto, kde se m\u016f\u017ee nap\u00edt.<\/p>\n\n
Pokud va\u0161e ko\u010dka nepije dostatek vody, m\u016f\u017eete zkusit do vody p\u0159idat trochu chuti. M\u016f\u017eete to ud\u011blat p\u0159id\u00e1n\u00edm trochy tu\u0148\u00e1kov\u00e9 \u0161\u0165\u00e1vy nebo ku\u0159ec\u00edho v\u00fdvaru do vody.

Ko\u010dky jsou fascinuj\u00edc\u00ed tvorov\u00e9 a jejich schopnost vzdorovat gravitaci, kdy\u017e pij\u00ed, je jen jednou z v\u011bc\u00ed, kter\u00e9 je d\u011blaj\u00ed tak v\u00fdjime\u010dn\u00fdmi.
