APAKAH MAKSUD DEUTEROSTOME dalam CORSICA?
Deuterostome
Deuterostomes adalah superfilia haiwan. Mereka adalah subtaxon cawangan Bilateria subregnum Eumetazoa, dan menentang protostom. Deuterostomes dibezakan dengan perkembangan embrio mereka; dalam deuterostomes, pembukaan pertama menjadi dubur, sementara di protostom ia menjadi mulut. Deuterostom juga dikenali sebagai enterocoelomates kerana koelom mereka berkembang melalui enterocoely. Terdapat empat filamen tetap deuterostomes: ▪ Phylum Chordata ▪ Phylum Echinodermata ▪ Phylum Hemichordata ▪ Phylum Xenoturbellida Superphylum Deuterostomia telah ditakrifkan semula pada tahun 1995 berdasarkan analisis urutan molekul apabila lophophorates dikeluarkan dan dikombinasikan dengan haiwan protostom lain untuk membentuk superphylum Lophotrochozoa. The phylum Chaetognatha juga boleh dimiliki di sini. Kumpulan yang memunah mungkin termasuk Vetulicolia filum. Echinodermata, Hemichordata dan Xenoturbellida membentuk Clade Ambulacraria. Philum Priapulida juga mempunyai perkembangan deuterostomic, walaupun diletakkan di dalam protostom. Dalam kedua-dua deuterostomes dan protostomes, zigot pertama mula berkembang menjadi bola kosong yang dikenali sebagai blastula.
Definisi deuterostome dalam kamus Corsica
Takrif deuterostome dalam kamus adalah mana-mana ahli kumpulan utama haiwan yang ditakrifkan oleh fakta bahawa semasa pembukaan embrio awal pembukaan pertama menjadi bentuk dubur haiwan. Sebaliknya adalah protostom.
