Intshayelelo: Ukuqonda iPhysiology yeLizard
Amacikilishe zizidalwa ezinomtsalane ezikwiqela lezilwanyana ezirhubuluzayo. Ziziindidi ngeendidi zeemilo, ubukhulu, nemibala eyahlukahlukeneyo yaye zifumaneka phantse kuzo zonke iindawo zehlabathi. Ukuqonda i-physiology yabo kubalulekile ekufumaneni ukuqonda malunga nokuziphatha kwabo, indawo yokuhlala, kunye neendlela zokusinda. Enye yezona zinto zixoxwa kakhulu ngefiziyoloji yecilikishe kukuba zinegazi elibandayo okanye zinegazi elishushu.
Yintoni Ubushushu begazi?
Ubushushu begazi, obukwabizwa ngokuba yi-endothermy, kukukwazi kwento ephilayo ukulawula ubushushu bomzimba wayo ngaphakathi. Izilwanyana ezinobushushu zigcina ubushushu bomzimba obungaguqukiyo obuzimeleyo kwindawo engqongileyo. Bafezekisa oku ngokuvelisa ubushushu ngokusebenzisa iinkqubo ze-metabolic, ezifana nokuphefumla kweselula, kunye nokulawula ukulahleka kobushushu ngokusebenzisa iindlela ze-physiological, ezifana nokubila okanye ukungcangcazela. Izilwanyana ezanyisayo kunye neentaka ziyimizekelo yakudala yezilwanyana ezinegazi elishushu. Ziyakwazi ukuphumelela kwiindawo ezininzi, ukusuka kwiindawo ezibandayo ze-Arctic tundras ukuya kwezona ntlango zishushu.
Yintoni ukubanda kwegazi?
Igazi elibandayo, elikwabizwa ngokuba yi-ectothermy, lichasene negazi elifudumeleyo. Izilwanyana ezinegazi elibandayo zixhomekeke kwimekobume ukuze zilawule ubushushu bomzimba wazo. Azikwazi ukwenza ubushushu ngaphakathi kwaye ke kufuneka zigcakamele ilanga okanye zifune umthunzi ukuze zifudumale okanye zizipholise. Izilwanyana ezinegazi elibandayo zixhaphake kakhulu kumaqela ezilwanyana ezirhubuluzayo nakuma-amphibians. Zihlala zifumaneka kwindawo ezifudumeleyo okanye ezitshisayo kwaye azikwazi ukumelana nobushushu obugqithisileyo.
Ukuqonda iLizard Metabolism
I-Metabolism yiseti yeekhemikhali eziguqukayo ezenzeka kwizinto eziphilayo ukuze kugcinwe ubomi. Amacikilishe anemetabolism ekhethekileyo eqhelaniswa nendawo ahlala kuyo. Ziyi-ectothermic, nto leyo ethetha ukuba ubushushu bomzimba wabo bulawulwa yindawo ebangqongileyo. Imetabolism yazo icotha kuneyezilwanyana ezinegazi elishushu, kwaye ngokuqhelekileyo zifuna ukutya okuncinane ukuze ziphile. Bakwanayo nesantya esisezantsi semetabolism xa bengasebenzi, nto leyo ebavumela ukuba balondoloze amandla.
Ingxoxo : Ngaba Amacikilishe anegazi elibandayo?
Ingxoxo-mpikiswano malunga nokuba amacikilishe anegazi elibandayo okanye anegazi elishushu sele ineminyaka iqhubeka. Ezinye iingcali zithi amacilikishe anegazi elibandayo ngenxa yokuba akakwazi ukulawula ubushushu bomzimba wawo ngaphakathi. Bathembele kwimo engqongileyo ukuba bafudumale okanye baphole, kwaye ubushushu bomzimba wabo buguquguquka kunye nobushushu obungqongileyo. Nangona kunjalo, ezinye iingcaphephe zithi amacikilishe akanagazi libandayo, kodwa anesantya esikhethekileyo somzimba esiwela kwenye indawo phakathi.
Ingxoxo: Ngaba Amacikilishe anegazi elishushu?
Kwelinye icala, ezinye iingcali zithi amacilikishe anegazi elishushu ngenxa yokuba anokunyusa ubushushu bomzimba wawo ngokusebenzisa iindlela zokuphila. Ngokomzekelo, ezinye iindidi zamacikilishe zinokunyusa ubushushu bomzimba wazo ngokugcakamela ilanga okanye ngokungcangcazela. Basenokulawula ubushushu bomzimba wabo ngokuziqhelanisa nokuziphatha, njengokufuna umthunzi okanye ukugrumba ngaphantsi komhlaba. Ezi ndlela zicebisa ukuba amacilikishe anokuba nesantya semetabolism entsonkothileyo kunokuba bekucingelwa ngaphambili.
Ubungqina: Ukulinganisa Ubushushu bomzimba wecikilishe
Enye indlela yokubona ukuba amacilikishe anegazi elibandayo okanye ashushu kukulinganisa ubushushu bomzimba wawo. Uphononongo lubonise ukuba ezinye iintlobo zamacikilishe zinokugcina ubushushu bomzimba obungaguqukiyo nakwindawo eziguquguqukayo. Umzekelo, inamba eneendevu (i-Pogona vitticeps) iye yabonwa ukugcina ubushushu bomzimba obuzinzileyo ngaphakathi koluhlu olumxinwa, kungakhathaliseki ubushushu bendawo engqongileyo. Oku kuthetha ukuba amacikilishe anokuba nenqanaba elithile lolawulo lobushushu.
Ubungqina: Amanqanaba oMsebenzi wamacikilishe
Enye indlela yokuvavanya ukuba amacikilishe anegazi elibandayo okanye anegazi elishushu kukuqwalasela amanqanaba omsebenzi wawo. Izilwanyana ezinegazi elishushu zidla ngokusebenza ngakumbi kunezilwanyana ezinegazi elibandayo ngenxa yokuba zinezinga eliphezulu lokutya ukutya. Nangona kunjalo, uphando lubonise ukuba ezinye iintlobo zamacikilishe zinokusebenza kakhulu, nakwiindawo ezipholileyo. Oku kucebisa ukuba amacikilishe anokuba nesantya semetabolism entsonkothileyo kunokuba bekucingelwa ngaphambili.
Ubungqina: Indawo yokuhlala yamacikilishe kunye neMozulu
Indawo yokuhlala yamacikilishe kunye nemozulu zibonelela ngemikhondo eyongezelelweyo kwifiziyoloji yabo. Izilwanyana ezinegazi elibandayo zihlala zifumaneka kwiindawo ezifudumeleyo, apho zinokutshisa ilanga ukuze zifudumale. Noko ke, amanye amacilikishe afumaneka kwiindawo ezipholileyo, njengeentaba zeAndes. Oku kucebisa ukuba amacikilishe anokuba nesantya semetabolism entsonkothileyo kunokuba bekucingelwa ngaphambili.
Ukuqukumbela: Ngaba Amacikilishe anegazi elibandayo okanye anegazi elishushu?
Ingxoxo-mpikiswano malunga nokuba amacikilishe anegazi elibandayo okanye anegazi elishushu iyaqhubeka. Ngelixa ezinye iingcali zisithi amacilikishe anegazi elibandayo, ezinye zibonisa ukuba i-physiology yawo intsonkothile kunokuba bekucingelwa ngaphambili. Ubungqina obuphuma kuphononongo lobushushu bomzimba, amanqanaba omsebenzi, kunye nendawo yokuhlala bucebisa ukuba amacilikishe anokuba nesantya esisodwa sokugalela umzimba esiwela kwenye indawo phakathi.
Iimpembelelo: Kuthetha ntoni kukuziphatha kwecikilishe?
Ukuqonda ukuba amacikilishe anegazi elibandayo okanye anegazi elishushu kunefuthe kwindlela aziphatha ngayo. Ukuba amacilikishe anegazi elibandayo, asenokungasebenzi kwindawo epholileyo kwaye anokufuna ixesha elingakumbi lokufudumeza phambi kokuba asebenze. Nangona kunjalo, ukuba amacilikishe anesantya semetabolism entsonkothileyo, angakwazi ukuziqhelanisa noluhlu olubanzi lweemeko kwaye abonise ukuguquguquka okukhulu kokuziphatha.
UPhando lwexesha elizayo: Ukuphonononga i-Lizard Physiology
Uphando lwexesha elizayo malunga nefiziyoloji yecilikishe luya kukhanyisa ngakumbi isantya semetabolism kunye nolawulo lobushushu. Inkqubela phambili yetekhnoloji, efana nokucinga kwe-thermal kunye nohlalutyo lwemfuza, inokubonelela ngengcaciso entsha malunga nendlela amacilikishe alawula ngayo ubushushu bomzimba kunye nokugcina i-homeostasis. Ukuqonda i-physiology yamacilikishe kubalulekile ekulondolozeni ezi zidalwa zinomdla kunye nokukhusela iindawo zazo zokuhlala ukwenzela izizukulwana ezizayo.
