Kodi mtundu wa chitukuko amatchedwa postembryonic? Postnatal nthawi

anthu ochepa chabe amene amaganiza kuti aliyense siteji ya moyo uli dzina lakelake. Choncho, sayansi imadziwa ndi postembryonic chitukuko embryonic. nthawi awa amasiyana mzake ndipo ndi makhalidwe osiyana. M'nkhaniyi tiona zotani chitukuko amatchedwa pambuyo embryonic. Mudzaphunzira mitundu ya nthawi ndi mbali.

Kodi mtundu wa chitukuko amatchedwa postembryonic?

Mphindi pamene Ndisanaumbidwe wosiya nembanemba ndi kusintha kwa nyengo embryonic mu postembryonic. Mu anthu, nthawi otchedwa kubadwa. Dziwani kuti zinthu zosiyana wamoyo, ndondomeko izi ndi zosiyana kwambiri.

Mitundu ya zamoyo

nthawi Postnatal akhoza yodziwika ndi mitundu iwiri ya chitukuko. Science kudziwika mwachindunji kapena mozungulira kusinthika kwa zamoyo.

chitukuko mwachindunji

Mtundu wa kutembenuka imakhudzanso thupi, amene ndi ofanana kwambiri ndi wamkulu. Choncho, postembryonic chitukuko anthu ali ndi maganizo mwachindunji. Izi iwonso monga chitukuko cha nyama ndi ena zokwawa.

Atabadwa mwana wosabadwayo ndi zofanana kwambiri ndi chamoyo wamkulu. Komabe, kumasiyana kukula ndiponso alibe luso.

Sitipereka chitukuko, kapena metamorphosis

Postembryonic nthawi atha mawonekedwe mosadziwika (metamorphosis). Pankhaniyi nembanemba pamaoneka chamoyo zosiyana kwambiri ndi akulu. Izi zikhoza zina invertebrates, mollusks ndi zokwawa. Mwachitsanzo, mukhoza kutenga gulugufe wamba. Post-embryonic chitukuko cha chamoyo, mu nkhani iyi amakhala ndi pokhala nawo mawonekedwe a mphutsi. Pokhapokha Gulugufe amakhala ofanana wamkulu.

Khalidwe postembryonic nthawi (chitukuko mwachindunji)

Monga tanena yomweyo pambuyo thupi latsopano masamba zimagwira ntchito zosiyanasiyana, ndi gawo latsopano iyamba kukhala. Post-embryonic chitukuko cha munthu zigawo zingapo. Chomaliza ndi kutha msinkhu. Taganizirani njira zofunika postembryonic nthawi.

Mayeso oyamba a chitukuko, anabadwa miyezi isanu ndi umodzi

Pa nthawi imeneyi mwana likusinthira ku chilengedwe chatsopano. Iye amaphunzira kumvetsera ndi kuika maso anu pa zinthu zina. Zakudya panthawi imeneyi chitukuko cha madzi kwambiri. Mwana sangathe kudya zakudya wamkulu paokha, ndi zikudalira mayi. Ana ena ali nsanga kukhala kuposa ena. Iwo amapita ku mlingo yotsatira pambuyo embryonic nthawi mofulumira. Mwachitsanzo, ena ana mu miyezi sikisi kale angaime, kukhala ndi kukwawa. Komabe, luso chabe thupi. Science samadziwika Komabe pamene mwana pa nthawi imeneyi anayamba kulankhula zomveka chinenero wamkulu.

Dziwani kuti nyama zambiri ndi zokwawa, yomwe ndi njira yolunjika pambuyo embryonic chitukuko, moyo chimodzimodzi. Komabe, iwo angakhale okhudza nthawi imeneyi, mofulumira kwambiri kuposa munthu.

Gawo lachiwiri la chitukuko: chaka chimodzi

Pa nthawi imeneyi, munthu pang'ono kuphunzira kukhala kukwawa ndi kuyamba kuyenda. Mbali imeneyi amakhala ndi kupeza luso thupi. Komanso, thupi wamng'ono pang'onopang'ono azolowere chakudya chatsopano. ana ambiri pa siteji amayamba kuti apereke phokoso latsopano. Choncho kuphunzira kulankhula chinenero anamvetsa ndi munthu wamkulu. Ngati mwana kukula mofulumira, panthawi imeneyi akhoza kale kulankhula mawu ena kapena ziganizo yosavuta.

Zokwawa, ndi zinyama nthawi ili kale wokonzeka moyo wamkulu. Iwo akhoza kupanga wokha chakudya ndi Musati muzidalira pa akulu.

Chachitatu nthawi: kukula ndi maphunziro

Thupi la munthu amakhala ndi chitukuko yaitali pambuyo embryonic. Pa nthawi imeneyi mwana kale mwina yokha kudzisamalira, koma kukhala moyo popanda makolo adakali zovuta. Mu moyo wamba, ana pa mlingo nawo chisanadze sukulu kenako mabungwe sekondale. Iwo amakula, kukhala ndi kuphunzira chirichonse chimene iwo adzafunika mu moyo wamkulu.

Nyama ndi nyama pa siteji iyi kale anamaliza nthawi Postnatal ndi amaonedwa akulu.

Nyengo chachinayi: msinkhu

Choncho, mtundu wa chitukuko amatchedwa pambuyo embryonic, mukudziwa kale. Mu anthu, itha bwanji 16-20 zaka. Pa nthawi imeneyi anayamba ntchito mbali zofunika za thupi. Pituitary ndi zopangitsa adrenal kutulutsa mahomoni ena. Mu akazi, thumba losunga mazira imayamba kugwira ncthito kuwoneka kusamba. amuna tikule pogonana ndi kupitiriza mtundu wake.

Postnatal anamaliza pa kusintha kwa mukadzakula. Man kale ndi moyo wosadalira ndi kulenga banja lawo.

Kaperekedwe yozungulira chitukuko pambuyo embryonic

Monga momwe zinalili m'mbuyomu, chitukuko ichi lagawidwa magawo angapo. Tiyeni tione iwo mwatsatanetsatane.

sitepe yoyamba: pambuyo pa kubadwa kwa

Chikadzangotha thupi masamba zimagwira ntchito zosiyanasiyana, ndi kusintha kwake zina amayamba. Pa nthawi imeneyi, chitsanzo latsopano n'zosiyana kwambiri ndi wamkulu. Ndi osiyana kwambiri maonekedwe ndi chitukuko mkati.

Chinthu chachiwiri: Transformation

Apa pali amphamvu kusintha latsopano chamoyo. Mtundu uliwonse wa amoyo, kumachitika m'njira zosiyanasiyana. Munthu zimakhala zofanana ndi nyama wamkulu kapena nyama. Komabe, tizilombo ambiri ali pa siteji ichi kuwasamalira komanso kuwateteza. Iwo sangakhoze koma zowathandiza.

Mbali yachitatu: kupeza maluso

Sitipereka chitukuko postembryonic ndi chomaliza, amene amakhala ndi kupeza zinthu zina. Zikuthandizaninso tsogolo la chamoyo kuti moyo paokha osati kudalira anthu achilendo.

Chidule ndi mapeto

Tsopano inu mukudziwa mtundu wa chitukuko amatchedwa pambuyo embryonic. Tikumbukenso kuti kutembenuka mozungulira atuluka zambiri mofulumira kuposa molunjika postembryonic nthawi.

Man amaloŵamo motalikitsa nthawi imeneyi. Komabe, luso anthu kulola kuti apulumuke ngakhale zovuta kwambiri. Izi si zokwawa ndi nyama. Chitukuko anthu mu nthawi pambuyo embryonic, zotsatirazi madokotala: dokotala, katswiriyu ndi ena. Komanso mosamala kwambiri kusunga makolo a mwanayo.

Aliyense ayenera kudziwa Postnatal nthawi. deta koyamba za nthawi kale ndi maphunziro zamoyo. Kuti mudziwe amenewa amathandiza kukhala dziko lawo.
