Animal tissues develop from embryonic germ layers. Triploblastic animals have three germ layers (ectoderm, mesoderm, and endoderm) and three basic body plans related to body cavities (acoelomate, pseudocoelomate, and coelomate).
Select the three statements that are true.
1) A diploblast has no mesoderm.
2) In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the lining of the digestive tract.
3) A pseudocoelom has the same functions as a true coelom.
4) The digestive tract of a coelomate functions as a coelom.
5) In a pseudocoelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the muscles.
6) An acoelomate triploblast has no endoderm.
7) In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.

7. In a coelomate, tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity

Explanation:

1. Because the mesoderm is one of the three prymary layers in the early stage of an embryo.

2. The pseudocoelom is a body cavity named this way because it is not entirely lined by mesodermal cells like the true coelomic cavity. It provides the turgor hydrostatic pressure for the animal as a whole, works as a lubricant between issues and provides a medium for intercellular signaling and nutrient transport. It contains the coelomocytes.

7. That is the difference between the coelomate and the pseudocoelom. The coelomate clothe the main body cavity and is located inside the body to surround and contain the alimentary canal and other organs. It works like a protection layer in most of animals.
