Ziwalo magazi ndiponso udindo wawo gulu la nyama ndi zomera

Masiku ano m'dziko muli pa 100 zikwi. Nyama ndi zomera padziko lapansi lino ndi ife. Ambiri a iwo mbali yofunika kwambiri mu unyolo zamoyo okwanira, amene Sindingachite popanda biogenesis alipo. Pakuti mayiko kuphunzira zomera ndi nyama ufumu, asayansi padziko lonse akhala yafupika zonse zodziwika zamoyo mu gulu ina, kaphatikizidwe malinga ndi makhalidwe ambiri amalandira. Kudziwa nyama iliyonse tizilombo kapena chomera mtundu winawake wa sewerolo chachikulu ntchito magazi ziwalo, amene dongosolo lomwelo ziwalo zosiyana nyama ndi mbalame.

Mwachitsanzo, ziwalo magazi a mbalame zonse ndi mapiko ndi mchira, nyama zonse - nthambi anayi, zomera - masamba ndi maluwa, ndi zina zotero. Chifukwa cha ichi ife tonse titengako ku kudziwika nyama, mbalame, zomera ndi nsomba magulu ena ndi mitundu. N'zochititsa chidwi kuti aliyense mtundu uli mwini zochititsa onse ofanana ndi osiyana zofunika mu anawayerekezera ndi zina zamoyo.

ziwalo magazi amaimira akuluakulu otchulidwa yeniyeni ya mtundu winawake wa chamoyo chimene kulola nyama adzakhala mu malo makamaka. Choncho, onse nsomba moyo mu nyanja madzi ndi ndi wazikang'a pamwamba omwe akutumikira monga suti zodzitetezera kulola nsomba kukhala wosaoneka madzi, n'zosavuta kupita ku chizunzo, komanso kudziteteza kwa adani zotheka ndi mitundu ina. Monga ziwalo magazi a nsomba zonse pa dziko ndi mchira ndi zipsepse, imene nsomba kusambira m'madzi.

The kwambiri mfundo ziwalo magazi anachokera ku mawu Latin "gomos" kutanthauza "olingana." Ndiko kuti, ndi matupi ndi kapangidwe chomwecho, komanso malo ofanana mu thupi la nyama kapena zomera. Komabe, kufanana imeneyi salola kulankhula za ntchito mofanana basi iwo angakhale osiyana kwambiri. Mwachitsanzo, dongosolo lofanana ndi dongosolo chigoba cha forelimbs nyama zonse ndi mbalame. Komabe, nyama kupiphatisa kuyenda pa dziko, mbalame - ndege, ngakhale ngati inu kuphwanya dongosolo awo mkati, izo ndi zizindikiro zofanana kwambiri.

Ngati ife kulankhula za ufumu chomera, ziwalo zawo magazi anapereka pamakhala, stamens, tsinde, mizu ndi zipatso. Mu mbewu iliyonse kumeneko nitievo-nthambi mizu, alipo mbewu umachitika pa nthaka, komanso amalandira mphamvu phulusa, mchere ndi zinthu organic m'nthaka. Mbale masamba a zomera ntchito mpweya kuloŵerera ndi evaporation a chinyontho, ndi yaitali elongated zimayambira akuyenera kubweretsa pamwamba kuwala ndi mpweya assimilating maluwa ndi masamba kwa kubereketsa zomera bwino ndi mbewu kafalitsidwe.

Asayansi apeza ziwalo magazi a zomera kalelo, ndipo pokonza mapepala ake sayansi, anthu ambiri anzeru ndi chitsanzo cha miyoyo ya nyama ndi zomera monga maziko a zogwirizana kuli zolengedwa zonse kwachilengedwenso padziko lathuli. Tiyeneranso kumvetsetsa kuti mu ndondomeko ya zamoyo zinachita chitukuko ya zomera ndi nyama zambiri akhala akukonza ena kusintha, chifukwa cha zimene akuluakulu ena ataya kufunika kwake ndi atrophied, pamene ena zayambika, kukhwima ndi anatenga mbali yaikulu mu moyo wa munthu wamoyo. Choncho, asayansi kamodzinso kukhulupirira kulondola kwa choonadi yosavuta kumva kwachilengedwenso - ngati munthu wina si ntchito, pang'onopang'ono afa kutali, kulola anthu ena kukhala olimba bwino.

Kufotokoza onse pamwamba, Tiyeni tifupikitse kuti ziwalo magazi ndi ziwalo zina zofunika kwambiri zolengedwa zamoyo amene ali yemweyo morphological mtengo Komabe, ntchito chosiyana malingana ndi mtundu wa chomera kapena chinyama mitundu. Ngakhale anasonkhanitsa sayansi pa nkhani imeneyi, pali malo mudziwe zambiri.
