Lokuzaliswa nokuthuthukiswa kwezilwane. Izinto for nesifundo

Ngisho i abanolwazi usosayensi sezilwane ngokuqiniseka okuphelele awukwazi ukusho ngokuthe ngqó ukuthi zingaki izinhlobo zezinto eziphilayo manje zikhona khona ngaphambi kule planethi. Ilokhu ekuvuleni izinhlobo ezintsha, futhi ubuso Zomhlaba, ngeshwa, anyamalale izinhlobo ubudala. Mhlawumbe yingakho ngakho kubalulekile ukwazi kabanzi mayelana kabusha kanye nokuthuthukiswa izilwane, ukuzama eyayenziwe ukuvimbela ukunyamalala, ukuzama icubungulisise ukufunda Kwase kusele kancane yokuqothulwa kwezinhlobo.

Kancane on the ngezigaba

Animal Kingdom has a lot of izinhlobo kanye amakilasi, kuhlanganise imiswenya, molluscs, ezinamagobolondo futhi echinoderms, arachnids nezinambuzane. A yezilwane ezinomgogodla zibalwa: inhlanzi, izilwane eziphila emanzini nasezweni, ezihuquzelayo, izinyoni, izilwane ezincelisayo. A ezihlukahlukene izilwane eziphilayo emhlabeni, ivezwa kahle viewports amasethi. Kodwa ezahlukene kanjalo nesakhiwo zayo, izilwane united zibe munye umbuso, kuhluke ngezindlela eziningi. Indlela nokuzalanisa izilwane? ngamaqembu ahlukene inqubo wenziwa ngezindlela ezahlukene. Ake sibheke izinhlobo eziyisisekelo.

agamobium

Kwamanye izilwane aphansi (ezingenamgogodla), ebonakala ukukhiqizwa kabusha asexual, njengoba indlela elula ukwakha futhi andise inzalo. Animal Lokuzaliswa nokuThuthukiswa yalolu hlobo Kwenziwa ukuqoqwa ngqo noma luthela. izilwane ezinjalo zihlanganisa izimpethu, izipanji, jellyfish, Amphioxus nabanye abaningi. Empeleni, lezi akuzona izinto ezincane kangaka. Kodwa ubunjalo inqubo yokuziphendukela kwemvelo ukuze adale abanye, isikhathi esiningi-ukudliwa futhi inqubo eyinkimbinkimbi yokuzalana.

syngenesis

Lolu hlobo kudinga emabhilidini amabili ukudala inzalo: iduna nensikazi. Lokuzaliswa nokuthuthukiswa kwezilwane kwenziwa zidala noma amaqanda ngokuzala amankonyane (ngokuyinhloko ezincelisayo). Ngokwesibonelo, amaqanda, kanye izinambuzane, futhi arachnids, kanye izinyoka izinyoni. Spawn: izilwane zasemhlabeni, inhlanzi. Kodwa ezinye izinhlobo zezinhlanzi - viviparous (isib, guppies). Uzozala amawundlu wabondla ubisi yazo zonke izilwane ezincelisayo (kuhlanganise indoda). Olunye uhlobo, ukukhiqizwa kabusha okwenzeka ngaphandle iqhaza kwabesilisa. Lesi senzakalo ngokuthi parthenogenesis. Common e izibankwa izinyosi, isibonelo.

Ukuthuthukiswa isilwane

Iphinde kwenzeka ngezindlela ezahlukene. Ngakho izinambuzane, isibonelo, kukhona amaningi njengoba ezintathu izigaba: amaqanda, isibungu, isiphungumangathi, omdala ngabanye, bakwazi amaqanda. Futhi ezinye ukukhiqizwa kabusha izinhlanzi kanye nokuthuthukiswa izilwane kwalesi silwane kwenzeka emlonyeni insikazi, lapho uthela amaqanda kuze kufike inzalo. Amphibians kusukela iqanda eba ifomu Intermediate - the ngunoshobishobi zazo kakade kwakhiwa frog omdala. Turtles nezinyoka siyinzalo etholakala ngqo kusuka amaqanda, nanjengezinyoni ezibanjwa. Zonke izinhlobo mammalian kukhona viviparous, ngisho amahlengethwa, okuyinto ubalwe njengenye izinhlanzi lasendulo. Bona suckle inzalo ubisi, kungakho igama ekilasini. Nokuvuthwa lenzalo zinhlobo ezahlukene kwezilwane senzeka izinkathi ezahlukene, kusukela imizuzu embalwa amashumi eminyaka. Kakhulu "fast" - butterflies wosuku olulodwa kanye nezinye izinambuzane. kancane kakhulu ukukhula isizukulwane young - in a kakhulu ekilasini ezincelisayo.
