Masikhumbule izifundo biology: ezincinane - oku ...

Kwizidalwa - a ophilayo mass zokudada. Yenziwe ezigidi ezinto eziphila. Eli gama livela lesiGrike, lithetha "ukuhambahamba" okanye "uhamba kunye yangoku."

Amanzi njengendawo yokuhlala

Phakathi iintlobo ezininzi enezityalo nezilwanyana ezisentlabathini akafumaneki eziphilayo lixesha ingaba yenziwe emoyeni. Nkqu "iiflaya" abanezakhono, ezifana Swallows, hayi bangasoloko zinganxitywa ngaphantsi ngamafu. Ngapha koko, ngexesha lokuzala, ukuba ekufukameni amaqanda, hatching, nanzo ebotshelelwe ilizwe, Noko ke, njengabo kwezinye iintaka. Ewe, iintaka bengenako ngonaphakade ukubhabha, kufuneka lokuphumla amaxesha ngamaxesha. Kanye imeko efanayo kunye nezinambuzane. Bachitha ixesha elingephi ekwenzakaleni emoyeni. Zonke iinkqubo zabo kubalulekile ebomini, ezifana ukutya, ukuzala, uphuhliso, uthathe indawo emhlabeni. Kwakhona ezinxulumene zomphandle kunye nobume bomhlaba kwihlabathi izityalo, ukusukela lenyama kweseli olunye-namaplanga nokuyifeza ngeninako. Ulwalamano ezahlukeneyo ngokupheleleyo kunye zokuhlala eziphilayo zasemanzini (hydrobiosis). Oku kubangelwa yinto yokuba iimpawu ezibonakalayo amanzi kunye nomoya ezahlukileyo. Amanzi ezixineneyo nondiliseko enkulu kakhulu. Kubonakala ukuba amandla lokuphakamisa medium mkhulu ngaphezu koko umoya. Ngako oko, bemi amanzi gqolo (okanye noko ixesha elide lobomi wayo) kuhlala ukumiswa emanzini, ngaphandle adibane emazantsi. Kuba ezi zinto ziphilayo musa inkxaso na emhlabeni, yaye eliphakathi zolwelo ngokwayo. Yiloo nto kuba "adadayo" ezinjalo eziphilileyo emanzini, abe nokukhulula-ezidadayo, okanye eziphilayo planktonic. Enyanisweni, kwizidalwa - iseti eziphilileyo.

Yenziwe ngoobani kunye iimpawu 'ezula "eziphilayo

Ubukhulu becala ukuya kwizidalwa zizilwanyana ezincinane kakhulu kwakunye nezityalo ngemikroskopu - ezininzi kubo kungabonwa ngeliso lenyama. Eyona uphawu eziphilayo planktonic ukuze ekhankanyiweyo ngokwentelekiso okwanamhlanje oluvakaliswe amandla intshukumo ezimeleyo. Abaninzi kubo, ndayihluthwa nayiphi na imizimba inoxanduva intshukumo, kwaye ngengqiqo ngokupheleleyo ilizwi amaza yokudlala. Ukuba Limbo yezityalo nezilwanyana unetyala ndandifeketha yalo emangalisayo. ubunzima balo likufutshane ubunzima amanzi apho lenkosikazi. Noko ke, ezincinane izilwanyana isenokuba eziphilayo ezikwazi intshukumo elizimeleyo. Oku kuchazwe bubukho amalungu ahlukeneyo sesindululo, ukuze bakwazi ukudada kakhulu edlamkileyo. Noko ke, intshukumo loo linqongophele kakhulu. Micro-eziphilayo abakwazi ukumelana nokuba ukuhamba olubuthathaka kakhulu kwamanzi. Kwaye ngenxa yokuba amandla intshukumo yabo ayinamsebenzi.

Njani na amaziko motion?

Okokuqala, kufanele kuqatshelwe ukuba kwizidalwa isilwanyana - oku ke intlanzi kwecacileyo, kwakunye intlanzi, lobster kunye nezinye izinto ezithi xa inqanaba lophuhliso osandul. izazinzulu German uphando elibonakalisa ukuba ezi zilwanyana "adadayo" kwikholam yamanzi abayi nje. Intlanzi ukuvelisa iintshukumo esebenzayo kakhulu phezu okwexesha elifutshane ixesha - baba ngokulinganayo Iphaphazelisa ukudada amabhovu, nanjengeentaka, zindanda emoyeni. Zalisa ukushiywa ajike athi kuya kukhokelela kunqandwa ukwehlisa crustacean kwi emazantsi. Lo mgaqo mnye kuxhomekeke amanye amalungu ezihamba kwi ezincinane izilwanyana. Umzekelo, kolovraschatelny isixhobo, apho bexhobe rotifers. Enyanisweni, izilwanyana planktonic ezinokufaniswa-moya, nto leyo igcinwe emoyeni ngenxa elijikelezayo. Kunye nokupheliswa isindululo rotary ke kancinane izicwangciso ze iye kuhlala ezantsi.

"Buffet"

Into ebaluleke kakhulu ukuba kusinda nezinto ezincinane izilwanyana kukuba lo mthombo uphambili ukutya, zezityalo izinto ezakha kwizidalwa, basasazekileyo ubunzima amanzi ziyatyeba, kwaye akaqhotyoshelwanga ezantsi echibini. Nale izilwanyana emininzi ukufumana ukutya kwazo ezifunekayo izinto ezibangqongileyo. babelawula ulwelwe bakwazi ukunika ubukho babo - oku kakhulu kokwanele kwaso abe echache ngokwaneleyo ukuba umzimba uchitha kwi intshukumo elizimeleyo kwakufuneka ukuhambisa esithubeni yamanzi. Ngaphezu koko, kwizidalwa (photo ngasentla abhengeze ngokupheleleyo le meko zendalo) kukho ubunzima ashinyeneyo kakhulu nto leyo, ukhonza njengomthombo wamandla izilwanyana zaselwandle kunye nentlanzi. Umzekelo, iminenga ukuba abalandeli emikhulu oku kutya ophezulu osidingayo kunye nabathengi zayo ezinkulu.

isiphelo

Ukushwankathela, kufanele kuqatshelwe ukuba gama ndaba enye intsingiselo kweli hlabathi lanamhlanje - i-ofisi "ezincinane". Olu lwazi abasebenzi, akuba kwanciphisa component yoyilo. Bayayigqiba ubomi babo ofisi kunye nezinye ii-ofisi. Kuba ezincinane ofisi ziquka: ezimali, oonobhala, abaphathi kunye nabanye. Imvelaphi walithiywa elithukayo lula ukuba achaze: enyanisweni, bonke abasebenzi - Qhotsa nje encinane. "Ezincinane", ngegama.
