Feem ntau echinoderms qhia pentamerous radial symmetry , tsib ntu sib npaug ntawm lub cev. Tshwj xeeb rau lawv cov phylum, echinoderms muaj dej vascular system, ib qho kev sib txuas ntawm cov kwj dej uas muaj cov kwj dej uas nrog rau cov leeg pob txha hu ua podia (tube taw tube taw Lub raj taw hauv cov ntses hnub qub yog teem rau hauv grooves raws caj npab Lawv ua haujlwm los ntawm hydraulic siab, lawv siv los xa zaub mov mus rau qhov ncauj qhov ncauj ntawm qhov chaw nruab nrab, thiab tuaj yeem txuas mus rau qhov chaw. https://en.wikipedia.org › wiki › Tube_feet

) cia cov kab mob no txav mus los ntawm ntug hiav txwv.
Vim li cas echinoderms muaj radial symmetry?
Lub cev yog motile thiab ob sab hauv kev sib luag. Bilateral symmetry txhais tau hais tias lub cev muaj peev xwm txiav tau nyob rau hauv nruab nrab thiab muab faib ua ob qho tib si ib nrab. Cov poj koob yawm txwv echinoderm tom qab tsim radial symmetry raws li nws tau xav tias yuav ua tau zoo dua rau cov hom.
Puas yog echinoderms radial symmetry?
Echinoderms nthuav tawm thib ob radial symmetry hauv qee qhov ntawm lawv lub cev ntawm qee theem ntawm lub neej, kev hloov pauv rau lawv qhov tsis muaj sia nyob. Lawv tsim los ntawm lwm cov tswv cuab ntawm Bilateria thiab muaj ob tog sib luag larvae.
Puas yog echinoderms radially symmetrical li cov neeg laus?
Larvae yog, los ntawm txhais, txawv heev ntawm cov neeg laus cov tsiaj, tab sis cov echinoderms tsuas yog paub cov piv txwv ntawm ob sab symmetrical larvae uas ua rau nce mus rau radially symmetrical cov neeg laus. Tsis yog txhua tus echinoderms muaj larvae, tab sis feem ntau ntawm lawv ua.
YPuas echinoderms puas muaj lub cev asymmetrical?
Nyob rau hauv cov evolution ntawm echinoderms, asymmetry tej zaum yuav muaj nyob puas tau txij li thaum lawv cov poj koob yawm txwv tau txais thawj morphologicalthiab morphogenetic zoo ntawm lub koom haum bilaterian (Daim duab 7). Qhov tseeb, kev tawm mus los ntawm ob sab symmetry yuav tsum tau tshwm sim txij li thaum nws pib hloov zuj zus.

Puas muaj lo lus symmetrical?
symmetrical Ntxiv rau daim ntawv Qhia Qhia. Tej yam uas symmetrical muaj qhov sib xws: nyob rau hauv lwm yam lus, ib sab yog tib yam li lwm yam. Yog tias koj tuaj yeem kos ib kab hauv nruab nrab ntawm ib yam dab tsi thiab tau txais ob qhov zoo sib xws, nws yog symmetrical .
Lub orbitals twg yog spherically symmetrical?
Tag nrho cov orbitals yog spherically symmetrical. Ntawd yog, ib qho hluav taws xob uas nyob hauv ib lub orbital tuaj yeem pom nrog qhov tshwm sim zoo ib yam ntawm txhua qhov kev taw qhia (ntawm qhov muab ncua deb) ntawm lub nucleus . Vim li cas p orbitals tsis spherically sib npaug?
Puas echinoderms puas muaj segmentation?
theem Taxonomic: phylum Echinodermata; Qib ntawm kev tsim kho: cov khoom nruab nrog cev tau los ntawm peb cov ntaub so ntswg; symmetry: radial, qee zaum ua ke nrog ob sab; hom plab: qhov muag tsis pom lub hnab nrog qhov txo qis heev, lossis ua tiav nrog qhov quav;
Echinoderms nyob qhov twg?
Echinoderms feem ntau pom muaj nyob hauv dej ntiav ze ze ntawm ntug dej lossis hauv thaj chaw reeftab sis kuj tuaj yeem nyob hauv qhov tob ntawm dej . Puas tag nrho cov echinoderms nyob hauv dej hiav txwv? Echinoderms yog cov kab mob hauv hiav txwv uas txhais tau tias lawv nyob hauv dej hiav txwv Lawv pom nyob hauv txhua qhov dej hiav txwv hauv ntiaj teb txawm tias muaj ob peb hom nyob hauv Arctic.
Lub ntsej muag symmetrical nyob qhov twg?
Mus rau TikTok lub koob yees duab npo thiab xaiv "Effects" ntawmhauv qab sab laug. Nias lub cim "Favorites" nyob ib sab ntawm "Trending" thiab coj mus rhaub cov lim. Coj mus rhaub koj lub vijtsam thaum ua yeeb yaj kiab kom tig lub lim tawm thiab qhib .
