Esini izilwanyana. buphindwe yezilwanyana. I nezilwanyana inkulu incinane

Abaninzi abanomdla zasendle kunye neempawu zayo. Kuyinto isipho kwikona zonke single zomhlaba. Kweli nqaku ungenza inkcazelo nje kuphela malunga izilwanyana kakhulu ezinkulu nezincinane ukufumana, kodwa ufumanise ukuba imisebenzi kufuneka esini izilwanyana kunye nenkqubo yokuzala.

ulwazi ngokubanzi malunga izilwanyana

Izilwanyana - bona abameli zobukumkani eziphilayo. Bathi ke into ephambili yesifundo ngezilo. Xa iiseli animal tsentrosfera langoku. Kungenxa yesi sizathu ke zabizwa ngokuba eukaryotes. Izinto eziphambili zezi zilwanyana ezenza ziquka:

• Ukutya elungiswe zizinto eziphilayo.
• intshukumo Active.

Abantu abaninzi bakholelwa ukuba ubukumkani yezilwanyana iquka ezincancisayo kuphela. Le mbono ephosakeleyo. Enyanisweni, izilwanyana nazo zibandakanya iintlanzi, iintaka, izinambuzane kunye nabanye abaninzi. Ngaphambili lo mbuso eziphilayo zihlanganise Cya banayo iseli enye kuphela. Ke igama elithi "isilwanyana" libhekisela kuphela eziphilayo multicellular.

Ukuza kuthi ga ngoku, ngaphezulu kwesigidi esinye izazinzulu wachaza iintlobo ezahlukeneyo kweentlobo zezilwanyana. Indawo yokuqala nekuhlala inani arthropods. Iingcali zithi zonke izilwanyana uvela amagciwane flagellated. Uninzi iintlobo ezaziwayo zezilo wabonakala 500 yezigidi kwiminyaka eyadlulayo. Noko ke, izazinzulu ezininzi abakholelwa ukuba oko kwenzekile kakhulu ngaphambili.
Zonke izilwanyana zitya nezinye izinto eziphilayo. Kungenxa yesi sizathu, ukuba heterotrophic. Zonke izilwanyana indlela yonikezelo yahlulwe maqela alandelayo:

• Ezidla uhlaza.
• Carnivorous.
• Gazi.
• Izidla.

Zonke izilwanyana zahluke kakhulu enye kwenye ebomini, indlela lokondla ukuzala. Kungenxa yesi sizathu ukuba bonke abameli yehlabathi zezilwanyana baqatshelwa ngokwahlukileyo.

Ubume amalungu okuzala kwi iigusha neebhokhwe. Iimpawu ze kwenkqubo sokuzala abana

inkqubo Reproductive amalungu ngokusondeleyo enxulumene nokusebenza umzimba uphela. injongo yazo - kukuqhubeka lweentlobo.

Zangasese zeegusha neenkunzi zeebhokhwe ziquka:

• Amasende.
• iingcingo imbewu, nezintya zazo.
• namadlala Sex.
• Kwisingxobo samatyhalarha.
• channel Genitourinary.
• Lobudoda.

Amalungu okuzala weebhokhwe neegusha bavelise ngeemililitha ezimbalwa yobudoda.

Iba lityhalarha - lelona candelo ephambili msebenzi oyindoda okuzala. Yeyona ukuyilwa zophuhliso sperm. Kananjalo kubalulekile ukuba siqaphele kukuba iba lityhalarha kuvelisa iihomoni eyindoda. Kule umzimba yemvu kukho ubunzima grams 300 ezinesiqingatha yebhokhwe.

Iba lityhalarha okweqanda imilo. Okulandelayo kuso appendage. Kukho isidoda oqolileyo isixa esikhulu ixesha.

Iba lityhalarha ise kwisingxobo samatyhalarha. Xa iigusha neenkunzi zeebhokhwe ukuba ibekwe phakathi kwamathanga. Lobushushu kwi samatyhalarha usezantsi kakhulu ngaphezu kwezinye iindawo zomzimba. Lo mba sisihle kuphuhliso yeekhomponenti yobudoda.

isikhumba scrotal anakho somdlavuza. Umphezulu layo ligutyungelwe entlonzeni. Phantsi eluswini lwenyama lilaphu bhetyebhetye. Yenza umqobo kunye iba lityhalarha ihlukane iinxalenye ezimbini.

Umsebenzi ongundoqo wesixokelelwano genitourinary ukuba nesizungu emzimbeni amadlozi kunye nomchamo. Umzimba iqulathe tunica muscularis isifo kunye, kwakunye umaleko cancellous.

Iimpawu kwenkqubo okuzala yeegusha ababhinqileyo kunye neebhokhwe

izilwanyana kweentlobo ezahlukeneyo esini zahluke kakhulu phakathi kwabo. Kungenxa yesi sizathu ukuba iqela ngalinye zezilo kufuneka ziqwalaselwe zodwa.
Ngu esini okuzala yeenkomo ezincinane elineempondwana zobufazi ziquka:

• Zamaqanda.
• tube tubes.
• Lobufazi.
• Esibelekweni.
• esini bangaphandle.

Amaqanda - elimbhoxo igunya. Bona zibekwe kwindawo umva asezantsi. Kungenxa kulo mzimba wambumba iiseli zesini ababhinqileyo kunye iihomoni. Phantse kumphezulu yonke zamaqanda ehlanganiswa epithelium germinal. Ngaphantsi yeyona ndawo follicular apho iqanda ibunjiwe, kunye follicle.

tubes - i ityhubhu emxinwa inxibelelanisa isibeleko. ubude bayo uyahluka 12 ne-16 cm. Kulapha ekukhulelweni kwenzeka.
Isibeleko - umzimba apho uphuhliso olungekazalwa. Ngexesha lenkqubo yabasebenzi oko utyhala usana ngaphandle nge emjelweni lokuzalwa. Isibeleko iqulathe iimpondo, umzimba kunye nentamo.

iinkomo Veliswa. Isichumiso kunye nokukhulelwa

Veliswa - yinkqubo sizalwa na esiphilayo. Eyona njongo ephambili yokuzala - le enomfanekiso ngohlobo lwazo ukuze zizale. Andise izilwanyana ezinomqolo kungenxa uqhagamshelwano ababini iiseli - yobudoda, iqanda. nokudaleka kunokwenzeka kuphela emva ukufikisa. Xa iigusha neebhokhwe kufikwa iinyanga 7-8 zobomi. Ukufikisa kungenzeka kamva. Kuxhomekeke iimpawu amatakane kunye emzimbeni.
Kulo nyaka, iigusha neebhokhwe baqhuba kwimijikelo ngokwesondo eziliqela. Ngamnye kubo kuthatha umlinganiselo iiveki ezimbini ukuya kweziyi-20. Ngexesha lomjikelo yonke kwenzeka emzimbeni iindidi utshintsho, ezizezi ukulungiselela ukuchumisa kunye nokukhulelwa.

Ukuba emva kokukhulelwa lokukhulelwa ekungazange kubekho injengayo, ngoko ke iimazi yinyongo ezincinane lwenzeka balancing eqongeni. Amalungu nesini izilwanyana azisekho ukwenza iqanda ubomi kunyaka 8-10.

Kwimeko ifakwe emzimbeni lemvu ababhinqileyo kunye neebhokhwe yande izondlo. Pregnancy kuthatha umlinganiselo kwama-5 iinyanga.

kwalapho kwi esini zobukumkani yezilwanyana

Amalungu nesini sezilwanyana kubangela impikiswano enkulu phakathi Izazi. Ngabo ke kwalapho. Ezinye Izazi bakholelwa ukuba iziko luvo ozimeleyo ekhoyo kwi amalungu zangasese. Nangona kunjalo, uphando nezinye iingcali musani ukuqinisekisa oku.

Isibeleko iquka inani elikhulu kwalapho ezinento kwamanye amalungu abalulekileyo. Oku kunceda ukuchaza isenzeko intlungu ezibukhali onenimba.

inkqubo Reproductive amahashe. Iimpawu kokukhulelwa

Veliswa amahashe sex izidumbu iimpawu ezininzi. Oku yaye phi na ke kuni unako ukufumana kwinqaku lethu.

Xa amalungu obuni lwangaphandle eyindoda ziquka lobudoda namasende. Amalungu ababhinqileyo okuzala ziquka zamaqanda, isibeleko, lobufazi kunye womntu obhinqileyo. Ixesha xa ihashe ilungele ukuba ibizwa ngokuthi ukuzingela. Unokuqhutywa iintsuku ezi-3 ukuya kwi-10. Emva kokuphela kwethuba ngokuzingela i imazi lingenako ukuthwala ukuba kubekho umntu oyindoda olusondeleyo ngenyanga. Ngokuqhelekileyo le nkqubo lwenzeka ehlotyeni okanye ekwindla lonyaka. Xa kunjalo, ukuba ukukhulelwa hayi eyenzekile, ixesha kuzingela iphindiwe.
Xa ukuzala amahashe basoloko besebenzisa amadlozi ngesirinji. Oku kukuvumela ukuba bahlukane iingxaki ngokuhanjiswa kunye ukuthingaza basetyhini ukuzalela. A ukukhulelwa ungafaka kuphela wezilwanyana. Ukuze wenze oku, yena uphonononga isibeleko ngokusebenzisa isikali. Esini isilwanyana ngexesha lokukhulelwa adumbe ngokuphawulekayo.

Pregnancy buhlala iinyanga ezili-11. Ngethuba lokuqhuba kwale nkqubo kuxhomekeke lokondla, umxholo kunye nobudala isilwanyana. Ixesha umjikelo ngokwesondo iimazi ziintsuku-20 ukuya kuma-24.

Amalungu omncinane zobukumkani yezilwanyana

Kuyinto ezisitheleyo izilwanyana kakhulu amancinci - yinto lwepaki. lemurs ezincinanana abahlala kwisiqithi eMadagascar. ukuphakama kwawo eliphezulu - 20 cm, kwaye inobunzima umlinganiselo akukho grams ngaphezulu kwama-300. Lemurs are ebusuku. Ezi zilwanyana ziphantsi prosimians usapho.
Izazi bakholelwa ukuba ukuze isilwanyana khona, ubunzima balo kufuneka ubuncinane 2.5 grams. Nangona kunjalo, kukho ukuxolelwa. Pygmy shrew emhlophe-unamazinyo inobunzima isiqingatha gram. Ukuze uphile ukutya rhoqo. Daily ukudla, nenomlanga shrew emhlophe-unamazinyo ungaphezulu kakhulu ubunzima bayo. Okumangalisayo kukuba, oko phantse akuthethi ubuthongo. Ukuze ukuba afe, kufuneka ukukhangela ngeenxa zonke ukutya nobusuku.

izilwanyana ezininzi ezincinane ngokufuthi kubangela uvuyo nolonwabo. Ngamanye amaxesha, ubukhulu zabo eyothusayo. It has data yayo amancinci kunye chameleon "ezincinane". Ubude bayo ayikho iisentimitha ngaphezulu kwesithathu, kunye nokukhula kwayo ngaphandle nomsila ngemilimitha 16 kuphela. Bafumanisa lonwabu ngo-2007. Izazi ziye ezichazwe kweminyaka emine kuphela eyadlulayo. "Ukunakekelwa" namalovane kukho imiqolo emibini zokutyhomfa ecaleni ephakeme.

Le nyoka incinane - a microhylidae. ubude yabo neesentimitha ezili-10. Microhylidae iinyokana ezo nto ezinobuhlungu. Amaqanda ziimbovane kunye nezinambuzane ezincinane zisetyenziselwa amandla kubo. Fihla ezi ezirhubuluzayo esantini okanye phantsi ngamatye. Okumangalisayo kukuba, lo obhinqileyo unakho ukwenza iqanda elinye kuphela. Nje kwenzeka, kuba usana isiqingatha ubungakanani unina wakhe.
