What are the types of coelom of platyhelminthes?
it does not have a coelom.
Which are the two body cavities that form during embryonic development?
Coelom and Peritoneal cavity
What is the difference between schizocoelous and enterocoelous?
Schizocoelous found in protostomes and this is destriptive for coelom development during which archentron froms and coelom begins as splits within the solid mesodermal mass. Entrocoelous found in deuterostomes and coelom development during which the mesoderm arises as lateral outpocketing of archentron with hollows that become coelomic cavity.
What is coelom and give its types?
coelom is a fluid filled cavity within the body between the epidermis and gut it is derived from mesoderm there are three types of coelomic cavity they are coelomemates psuedo coelomates and acoelomates
Which animal adaptation happened before the others?
bilateral symmetryTissue developmentDevelopment of a coelom
Mollusks are characterized by?
A. Bilateral symmetry B. Development C. The presence of a coelom All the above
What do you mean by true coelom?
The coelom is the body cavity of an animal. A true coelom is a body cavity that is complete from mouth to anus with no breaks; there are animals that have pseudocoeloms - mouths and anuses but no solid connection between the two.
After the coelom developed what process allowed for the evolution of the many types of protostomes?
the answer is gene flow
Do Chordata have coelom?
Yes, Chordata have a coelom. The coelom is a body cavity lined with mesoderm that forms during embryonic development and is present in most animals within the phylum Chordata. It serves several functions, including providing space for internal organs and allowing for their movement and growth.
What is the name for the space between the two layers of the mesoderm?
coelom
Do roundworms have coelom?
Yes. However, this is not a true coelom. Roundworms are pseudocoelomates -- their mesoderm lines the endoderm and ectoderm, but there is no connection between the two. Therefore, it does not satisfy the definition of a coelom. However, since there is a body cavity still, this animal is said to be a pseudocoelomate.
Does the development of a true coelom between the ectoderm and the mesoderm represents a true evolutionary advance over the pseudocoelomate body plan?
Yes, it does. This development shows an evolutionary advance.
