Kodi kamba ndi amphibian (amphibian) kapena chokwawa (chokwawa)?

Funso lakuti ngati kamba ali m'gulu linalake nthawi ndi nthawi limabuka pakati pa ana, okonda nyama, ndi anthu ongofuna kudziwa. Ena amakonda kuganiza za akamba amphibians (amphibians), ena mouma khosi amati ndi zokwawa (zokwawa). Ndipo komabe, ndani angayankhe moona mtima funsoli: Kodi kamba ndi amphibian kapena chokwawa?

Kamba ndiye woimira wakale kwambiri wa gulu lake

Malinga ndi gulu lachilengedwe, kamba ndi chokwawa (chokwawa). Ng’ona, abuluzi ndi njoka ndi achibale ake apamtima, omwe ali m’gulu la Zokwawa. Izi ndi nyama zakale zomwe zakhala padziko lapansi kwa zaka 250 miliyoni. Gulu la akamba ndilochuluka, limagwirizanitsa mitundu 230.

Ngati tilingalira zamagulu onse, ndiye kuti zikuwoneka motere:

• Ufumu wa Zinyama;
• mtundu Chordates;
• kalasi Zokwawa;
• Gulu la Turtle.

Dziwani zanu: Gulu la akamba ali ndi mitundu yokha. Ndipo amene amawasunga ngati ziweto ayenera kudziwa zimenezi. Ngati mitundu ya Feline imaphatikizapo mitundu yambiri yoweta, ndiye kuti palibe mitundu ya akamba, pali mitundu yochepa chabe.

Monga chokwawa, kamba ali ndi:

• chivundikiro cha chikopa chopangidwa ndi zigawo za khungu lakufa;
• miyendo inayi;
• chipolopolo (chinthu chosiyanitsa);
• kuthekera kokhala pamtunda ndi m'madzi;
• kubalana mbali: kuikira mazira.

Chinthu chosiyana ndi chosatheka kudzilamulira kutentha kwa thupi. Zimadalira kwambiri chilengedwe, kotero kutentha, zokwawa zimabisala, ndipo kuzizira zimatuluka kukawotcha dzuwa. Ngakhale zamoyo za m’madzi ndi pansi pa madzi za zamoyo zina, zimapuma ndi mapapu.

Izi ndi zochititsa chidwi: Nyamayo simatha kutuluka m’chigobacho. Amakhala ndi mafupa a mafupa omwe amakula pamodzi ndi nthiti ndipo miyendo yokha, khosi ndi mchira zimayang'ana pansi pake. Chigobacho ndi cholemera, kotero zokwawa zimachedwa, koma oimira m'madzi ndi othamanga kwambiri.

Nchifukwa chiyani akamba amatchulidwa ngati amphibians?

Mfundo yakuti kamba ndi amphibians ndi yozikidwa pa moyo wam'madzi. Pali malo (chipululu) oimira dongosolo, koma ambiri amagwirizanitsidwa ndi madzi: amakhala pafupi ndi madzi kapena amakhala moyo wapansi pamadzi, amapita kumtunda kukawotha ndikuyikira mazira. Amakhulupirira kuti kambayo ndi yofala kwambiri chifukwa imakhala pansi pa madzi kapena pafupi ndi madzi. Kutengera izi, amapatsidwa mawonekedwe a nyama zam'madzi zomwe zimakhala ndi kupuma kwa khungu, mphuno ndi mapapo ndipo sizingakhale popanda madzi (zimaswana momwemo).

Koma akamba apita patsogolo pang'ono pakusinthika kwawo ndipo si aliyense amene amafunikira madzi. Mitundu ya m'chipululu imachita popanda izo ndikuikira mazira mumchenga. Ndipo am'madzi amapita kumtunda kukapeza ana. Akamba ongoswa kumene amafunafuna kwawo. Oimira zamoyo zam'madzi amapuma ndi mapapu ndipo amakakamizika kutuluka m'madzi kuti amwe mpweya.

Izi nzosangalatsa: Kutalika kwa moyo wa chokwawa chokhala ndi chipolopolo kumadalira kukula kwake. Zitsanzo zazikulu zimakhala zaka 100 kapena kuposerapo, zapakati - mpaka zaka 70-80, ndipo mu "ana" ukalamba umakhala zaka 40-50.

Zitsanzo zikuphatikizapo kamba wamba ndi kamba wa makutu ofiira. Awa ndi anthu okhala m'madzi omwe amatha kukhala m'madzi kwa maola awiri, akutuluka kwa mphindi 2-10 kuti apume mpweya. Mu chikhalidwe choletsedwa, amatha kusintha kupuma kwa anaerobic (popanda mpweya), pamene njira zonse za thupi zimapita pang'onopang'ono. Amathera gawo la nthawi yawo m'madzi, monga amphibians, ndi gawo la nthawi yawo pamtunda, kukumbukira ubale wawo ndi zokwawa.

Malingana ndi zizindikiro zina, kamba amatha kukhala ndi amphibians. Koma mu chisinthiko chake chapita patsogolo kwambiri, pokhala ndi kupuma kwathunthu kwa m'mapapo ndi kutaya kudalira kwathunthu pamadzi (sitikulankhula za oimira m'madzi a zinyama). Choncho, n'zosathandiza kukangana kuti kaya ndi zokwawa kapena amphibians. Akatswiri a sayansi ya zamoyo, ataganizira za ubwino ndi kuipa kwake, akhala akuziika kalekale ngati zokwawa.
