Answer 1

Hello friend..........

______________________________


Answer =>

A )✔️✔️ In acoelomates, either there is no mesoderm and coelom between ectoderm and endoderm example sponges and coelentrates, or a solid mesodermal parenchyma is present between the two example flatworms.


B) ✔️✔️In pseudocoelomates example roundworms, coelomic pouches are scattered in the mesoderm but no continuous cavity is present.


C)✔️✔️ In eucoelomates, a mesodermal -lined body
cavity, called coelom is present between the body wall and gut wall. it is formed either by splitting of Misoderm example schizocoelic coelom in annelids, authoropords and molluscs, or from eneterocoelic pouches of archentron example enterocoelic coelom in endoderms, hemichordates and chordates.
