it does not have a coelom.
The coelom is lined with epithelium.
yes it do hav a true body cayity or a coelom.
No
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.
The body cavity is a true coelom because it is lined by a layer of coelomic epithelium of mesodermal origin.

no
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.
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
the answer is gene flow
The presence or absence of a coelom (body cavity) is a key characteristic in the classification of animals. Animals can be categorized as acoelomates (no body cavity), pseudocoelomates (body cavity between mesoderm and endoderm), or coelomates (body cavity within mesoderm). This classification is important in understanding the evolutionary relationships and anatomical differences among animal groups.
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
The coelom is lined with epithelium.
Worms are not considered to be mollusks. Many types are annelids, such as earthworms, and others are nematodes or platyhelminthes.
