Umthombo wamandla mammalian kuyinto ... Uyini umthombo oyinhloko yamandla ezikhungweni zokuphehla ezincelisayo olusanda kuzalwa?

Sekuyisikhathi eside Class ezincelisayo kube isikhundla okuholela nakuzo zonke izilwane. abameleli balo izici eziphambili kakhulu ukwakheka kwazo zonke izinhlelo sitho, kuhlanganise wokugaya ukudla. Ukudla kusukela ekuzalweni ibalulekile khona kwabo kanye ayanda.

Ngobani ezincelisayo?

Class ezincelisayo esihlanganisa wonke amalungu uhlobo kuzithinta, okuyinto ukondla izingane zabo ubisi. Futhi akunandaba, kuyoba umelele encane igundane ensimini noma indlovu giant Afrika. Ekuzalweni kwakhe, umthombo mammalian energy nje ubisi.

Ukudla kusukela imizuzu zokuqala ngemva kokuzalwa kwenzeka kulezi izilwane usebenzisa webele ezikhethekile. Ngokusho imvelaphi yabo Ushintshe umjuluko.

Ngo ezincelisayo bakudala ezifana platypus futhi echidna, basuke kakhulu kabi athuthukile futhi ivulekele ngaphandle nge ikhule ezimbotsheni ekhethekile. Lezi zilwane kuningi enifana nawoyise - izinyoni. Okokuqala kuyinto nokuba khona cloaca - umgodi ezikhethekile kulo secrete imikhiqizo yabo ngokobulili, wokugaya ukudla bese izinhlelo excretory. Ngo-marsupial abameleli - kangaroo, i-koala, wombat - Amapayipi ubisi evulekile esikhumbeni emphethweni. Kwakungenxa ngomntanakhe uchitha isikhathi zokuqala ngemva kokuzalwa, ikhotha umkhiqizo oluyigugu ngqo isikhumba. Ngenxa placenta kulezi izilwane ayiqondakali athuthukile, bezalwa encane, unviable, izimpumputhe enqunu, abakwazi ukuba khona ezimele.

Okuhluke kakhulu bazalwa ezincelisayo ephakeme. Avezwa kahle, abaningi bayakwazi ngokushesha emva kokuzalwa ukuhambisa ngokuzimela.

Lezi heterotrophs ezahlukene

mammalian amandla umthombo uchungechunge izinto zokwakha eziphilayo ngomumo eyenziwe, okungukuthi amaprotheni, lipids kanye carbohydrate. Ngakho bona, sengathi wonke amalungu kwezilwane kukhona heterotrophic. Kulesi bayehluka kakhulu ezitshalweni ukwazi yelanga ukuguqula ku-carbohydrate. Kodwa kubalulekile futhi heterotrophs.

Sekuyisikhathi eside ososayensi aphethwe uchungechunge ucwaningo, thola ukuthi kungani udinga ukukhanya kwelanga izilwane. He is isibonakaliso ekuqaleni molting, kulala kwasebusika, ukufuduka zonyaka, ukwakheka kwama-hormone ocansini. Ngokwandisa ubude inqubo kanye ukuvela inzalo kwande esincelisayo iqala emini.

Abantu abahlukumeza abanye

umthombo Mammalian wamandla kuyinto ukudla ngomumo. Kodwa lingena emzimbeni ngezindlela ezahlukene. Ngakho, izilwane ezidla ezinye ehlele wahlabela isisulu sakhe sodwa.

Ngenxa yalesi unih benezingane eziningi izici kwesakhiwo: imisipha, izimpiko abukhali namazinyo enamandla. Ngokusho kwenye izinyo yomdabu ohlangothini umhlathi ngamunye aguqulwa ku okuthiwa izinyo okuzingela. Lena Ushintshe izinyo impande, okuyinto ngenxa yobukhulu enkulu futhi besaba usiko ngisho akwazi ukwephula ubuqotho amathambo lohlaselwayo. Animal ukudla ecebile amaprotheni namafutha. Ngakho-ke, amandla ezivezwa ukusetshenziswa yayo, ngokwanele isikhathi eside.

Izindlela yokuthi kukhiqizwa ukudla okungakanani kuleli qembu kwezilwane buhluke kakhulu. Ezinye jaha isisulu kuze wonke amabutho ayo izobonakala isafa. Okunye kuhlasela inyamazane ngokuzumayo. Futhi ungaphumelela.

Abantu abahlukumeza abanye ehlukile indlela khona. Ngokwesibonelo, amabhubesi nezimpisi kungcono ukuhlala futhi azingele umtshitshi. Bears athande ukuba yedwa.

herbivorous

Kodwa amandla ungumthombo ukudla mammalian futhi ukulungele, okuyinto ingatholakala hhayi njengoba indlela "olunegazi". Amalungu amaningi kakhulu zomhlaba isilwane uthanda imikhiqizo amakhambi. Kuyinto okune-fibre eyigugu - a carbohydrate zemvelo. Ngokwesibonelo, namagundane walala imbewu esitolo izitshalo. A ruminants regurgitate kancane ezokuhlafunwa utshani bese ukugaya ketshezi. Ubunzima munye kuphela. Lena ukudla okunama-kilojoule amancane. Ezidla uhlaza kufanele udle kakhulu futhi njalo ziyofuna ukudla. Esikhathini nemibandela sezulu esipholile khona layo futhi kuncike isizini. Kanye nezinto ezidla lezi bahlale bezama ukuzitholela ezidla uhlaza abampofu. Kodwa ukubavikela njengoba kukhona eziningi izici. Okokuqala, it is a izinselo eqinile nezimpondo. Kodwa ngaphezu kwakho konke izilwane ezinjalo kusiza izinyawo ezisheshayo. Ngakho-ke, ukungatholi angena empini ukungalingani nesitha, ngokushesha ngangokunokwenzeka ukuze aphunyuke.

mncintiswano

Kuyaziwa ukuthi kwemithombo yezebhoduluko anqunyelwe ngokwanele. Ngakho-ke, isilwane kufanele ukulwela ukudla, indawo yawo yokuhlala ukutholakala zokukhosela abangaki azibandakanya nabo kwezocansi. Ngenxa yalokho, kukhona umncintiswano phakathi kwabantu zohlobo olulodwa noma ehlukile. Ngokwemvelo, kule nkinga, kwi eziqine. Ngenxa yalokho, ukuzihlela nokuzivumelanisa kwemvelo, okuyinto bungamandla ukushayela yokushintsha kwemvelo. Nge mbono, abaningi bathi. Kodwa ososayensi ucwaningo luye lwabonisa ukuthi izilwane eziphilayo ngaphakathi endaweni efanayo, ukudlula kwesikhathi baba kokungafani okukhulu e umbala, isakhiwo emazinyweni izitho eziningi.

Nutrition: amaphrotheni, amafutha, carbohydrate

izinto eziphilayo udle kanye ezincelisayo ukudla, lapho khona nezinguquko eziningana. Amafutha njengoba umthombo energy kukhona izinto okunama-kilojoule amaningi. Esikhathini esiswini, abahlukaniswe basuke phansi glycerol futhi fatty acid. Lokhu kukhipha amandla kabili kunangesikhathi ukuguqulwa efanayo kwezinye izinto eziphilayo.

Ebalulekile ekudleni izilwane ezincelisayo izingwejeje. Njengoba isizathu noma iyiphi isilwane, zifeza ukwakha, amandla, ukugcina umsebenzi zokuzivikela. Izingxenye abamelwe amaprotheni kukhona amino acid. Ososayensi baye babonisa ukuthi ezinye zazo kubalulekile. Lokhu kusho ukuthi lezi zinto ayikwazi kwemiqondo emzimbeni, kodwa kuphela basinikeze ukudla isilwane.

Amakhabhohayidrethi sebeqala kakade sokudiliza emlonyeni ngosizo enzyme of nezindlala salivary. izinhlobo ezahlukene ushukela kudingekile umzimba umzimba.

Phuza, izingane, ubisi!

Ukwakheka ubisi kusukela zinhlobo ezahlukene ezincelisayo kuyahlukahluka ububanzi ngokwanele ezinkulu. Kodwa labo abasha ukuthi ngokushesha nje emva kokuzalwa kabili isisindo ayo, ukudla, ocebile ikakhulukazi amaprotheni. Okunjalo ubisi umkhiqizo unogwaja, izinyamazane, izingulube, inyathi nezimvu. Ludingeka ekuthuthukisweni nasekukhuleni encane carbohydrate lactose umzimba isehlane izimbuzi izinkomo. ubisi ngokucebile namaminerali. Lokhu fount yangempela potassium, i-calcium, phosphorous, yensimbi. Futhi Vitamin cocktail. Riboflavin, ascorbic acid, retinol, thiamine - lokho akuyona uhlu oluphelele izinto. Ngakho-ke, ubisi Sekuyisikhathi eside kubhekwe nje kuphela esiphundu, kodwa futhi umkhiqizo ewusizo, njengoba kudingekile ukuba umzimba elikhulayo nengane encane.
