Among coelomates in which of these does development occur by radial cleavage and the anus forms before the mouth?
Animals with deuterostome development exhibit radial cleavage, where the cells divide parallel or perpendicular to the polar axis of the embryo. In deuterostomes, such as echinoderms and chordates, the anus forms before the mouth during embryonic development.
Are Platyhelminthes acoelomates, pseudocoelomates or coelomates?
Coelomates.
Do pigs have a coelomate?
Coelomate is another word for a body cavity during early development of an animal. All mammals including pigs are coelomates.
Coelomates that develop with the blastopore becoming the mouth are?
Coelomates that develop with the blastopore becoming the mouth are protostomes. An example of a protostome would be the Caribbean reef squid.
Is a rat a protostome or deuterostome?
A rat is a deuterostome. Deuterostomes are a group of animals that includes vertebrates like rats, as well as other animals such as humans. They are characterized by the way their embryos develop, which involves the blastopore forming into the anus first.
Among coelomates which of these develops by spiral cleavage and the mouth forms before the anus?
Annelids, such as earthworms, are coelomates that develop by spiral cleavage and have a mouth that forms before the anus during embryonic development.
Among coelomates in which of these does development occur by radial cleavage and the anus forms before the mouth?
Animals with deuterostome development exhibit radial cleavage, where the cells divide parallel or perpendicular to the polar axis of the embryo. In deuterostomes, such as echinoderms and chordates, the anus forms before the mouth during embryonic development.
Are mammalia deuterostomes?
Deuterostomes. All chordates such as birds and mammals are deuterosomes.
Are Platyhelminthes acoelomates, pseudocoelomates or coelomates?
Coelomates.
Which would you expect to be more complex animals- coelomates or acoelomates?
coelomates
Are there other coelomates besides earthworms?
Most animals are coelomates, including humans.
Do deuterostomes only develop a mouth?
no,deuterostomes only develop their nus fist.
Does the blastopore becomes the anus of the adult in invertebres sponges protostomes or deuterostomes?
deuterostomes
Is chaetognatha solidly advanced deuterostomes?
No, chaetognaths are not considered deuterostomes. They belong to the phylum Chaetognatha (arrow worms), which are classified as protostomes. They are characterized by certain developmental and anatomical features that distinguish them from deuterostomes.
Are arthropods deuterostome?
Deuterostomes
Are earthworms coelomates?
Yes, earthworms are coelomates because they have the "tube within a tube" body plan that characterises coelomates. More specifically, coelomates have a body cavity that is completely lined with cells derrived from the mesoderm (the germ layer of tissue found between the endoderm and ectoderm in embryonic development).
Do arthropod have pseudocoelom?
No, arthropods are coelomates
