Question

A difference between coelomates and pseudocoelomates is that
A. one has bilateral symmetry and one does not.
B. pseudocoelomates have a true coelom.
C. the gut of a pseudocoelomate is surrounded by the body cavity, and the gut of a coelomate is surrounded by the mesoderm.
D. the gut of a pseudocoelomate is surrounded by the endoderm, and the gut of a coelomate is surrounded by the ectoderm.

Answer 1

A difference between coelom and Pseudocoelom is that the gut of a pseudocoelom is surrounded by the endoderm, and the gut of a coelomate is surrounded by the ectoderm. So your answer is D.

Answer 2

Answer:

D. the gut of a pseudocoelomate is surrounded by the endoderm, and the gut of a coelomate is surrounded by the ectoderm.

Explanation:

Animals that have a body that have holes are called celomates. They have a complete structure and their bodies are protected by celoma, acting as a skeleton. The celloma is formed in the stage called the gastricula, where the first layer is near the body and is called the endoderm, and the other layer is in the ectoderm.

Pseudocoelomas do not have an adequate cavity, because their pseudo celloma is between the ectoderm and the endoderm. Its structure does not protect the body and require protection in different cases. An example is cnidarians.
