Answer 2

Answer;

Images 1 and 3 have pseudocoelom body cavity

Images 2 and 4 have coelom body cavity.

Explanation;

• A coelom is a body cavity that is completely within the mesoderm while a pseudocoelom is a cavity between the mesoderm and the endoderm.
• Coelomate animals have a coelom body cavity. Coelom cavity in mammals is the area that contains all heart and lungs as well as the gut.
• Acoelomate animals have no true body cavity. They include, Mesozoa, Cnidaria,etc.
• Pseudocoelomate animals have pseudocoelom. Their body cavity is not lined with mesodermal cells. This cavity exists between the mesoderm and the ebdoderm that makes the gut walls.
