∙ 14y agoThe evolution of a coelom allowed organs to be cushioned and to grow and move independently of each other. It also appears to have evolved with a complete digestive system, which is an advantage, because it allows nutrients to be extracted from food much more efficiently.

After the coelom developed what process allowed for the evolution of the many types of protostomes?
the answer is gene flow
Do coelenterates have a coelom?
No. A coelenterate is an animal (such as a jellyfish), whose main body cavity is also its alimentary canal (gut). Most animals, on the other hand, have a body cavity (called a coelom) that is separate from the gut. For instance, inside your own body, you have an alimentary canal (your esophagus, stomach and intestines) and a separate body cavity that contains your heart, lungs, liver, etc. In a coelenterate, there is only one cavity.
What kind of animals are acoelmates?
Acoelomates is the name given to animaks which lack a coelom. Coelom is true body cavity which is formed in mesoderm by different methods e.g. schizocoelous or enterocoelous.Coelom is lined by mesodermal epithelium . Phylum Platyhelminthis is included in acoelomates. Pseudocoelomates possess a pseudocoelom while coelomates possess a true coelom.
Coelom organs present in the frog?
ns present in the coelom
Do flatworms have no coelom?
flatworms are the only triploblastic organisms that lack a coelom
Why was the evolution of a coelom so important?
It can act as a hydrostatic skeleton
What is the significance of coelom in the classification of animals?
Body cavity or coelom is generally the third most important criteria, after levels of organisation and body symmetry, in the classification of animals. Animals can be classified into four types on the basis of the type of body cavity they possess:Acoelomate (coelom absent): includes animals like sponges, coelenterates and flatworms,Pseudocoelomate (false coelom present): includes roundworms, andEucoelomate (true coelom present): includes all chordates, besides rest of the invertibrates.

the answer is gene flow
What benefit do animals derive from having a coelom?

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.
What is the first major group to develop a true coelom?
exists in all animals.
What was one of the first animals to develop a true body cavity?
Polycheats Annelids were first animals to develop a true coelom .
What animals have a true coelom?
Depending upon the coelom, the animals are divided into1)Acoelomates - Eg: Platyhelminthes2)Pseudocoelomates Eg: Nematyhelminthes3)Eucoelomates: - Eucoelomates are further divided into two typesa) Schizocoelom -Eg: Annelida, Arthropoda, Molluscab) Enterocoelom -Eg: Hemichordata and Chordata
In animals without a coelom moving from one place to another can aid or hinder digestion?

Do flatworms have no coelom a pseudocoelom or a true coleom?
no
What are the types of coelom of platyhelminthes?
