What else can I help you with?
What is the name for the space between the two layers of the mesoderm?
The space between the two layers of the mesoderm is called the coelom. It is a body cavity that forms during embryonic development and gives rise to various organs, such as the heart, lungs, and digestive system.
What is the ventral cavity that develops in the embryo?
The ventral cavity that develops in the embryo is called the coelom. It is a fluid-filled cavity that forms during early embryonic development and gives rise to the body cavities in higher organisms. The coelom helps provide space for organ development and movement.
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
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.
Which animal adaptation happened before the others?
bilateral symmetryTissue developmentDevelopment of a coelom
Does the development of a true coelom between the ectoderm and the mesoderm represents a true evolutionary advance over the pseudocoelomate body plan?
The development of a true coelom represents an evolutionary advance because it provides more space for organ development and movement, leading to greater complexity and specialization in body functions. Having a true coelom also allows for better cushioning and protection of internal organs.
What are the types of coelom of platyhelminthes?
Platyhelminthes have an acoelomate body plan, which means they lack a true coelom. Instead, they have a solid body with a more primitive digestive cavity and lack a fluid-filled body cavity like true coelomates.
Mollusks are characterized by?
A. Bilateral symmetry B. Development C. The presence of a coelom All the above
The body cavity is a true coelom why?
A true coelom is a body cavity completely lined with mesoderm tissue. It provides space for organ development, protection, and flexibility. This type of coelom allows for efficient organ function and movement within the body.
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.
