Expert Solution & Answer

Summary Introduction

Introduction:

Metazoa is divided into two groups, i.e., Eumetazoa and Parazoa. Animals of Eumetazoa are with specialized tissues and Parazoa are animals with no tissues such as sponges.Chordates are more closely related to Echinodermsthan to Rotifers, becauseChordates and Echinoderms are formed from Deuterostomia. Diploblastic animals show radial symmetry and animals which are triploblastic show bilateral symmetry.Acoelomates do not have a body cavity, whereas, pseudocoelomates have a body cavity.

Answer to Problem 1ACQ

The correct answer is option (b).

Explanation of Solution

Explanation for the correct answer:

Option (b) both acoelomates and pseudocoelomates have a body cavity. The acoelomates do not have a body cavity. Hence, it is a false statement.

Explanation for the incorrect answer:

Option (a) eumetazoa have specialized tissues and the parazoa do not. The parazoa lack the tissues, they only have cellular level of organization. Hence, it is a true statement.

Option (c) Chordates are more closely related to echinoderms than to rotrifers. The echinoderms and the chordates belong to the deuterostomia and the rotrifers belong to the protostomia. Hence, chordates are more closely related to echinoderms than to rotrifers is a true statement.

Option (a) some animals have radial symmetry and have bilateral symmetry.Different animals have different symmetry. Hence, it is a true statement.

Conclusion

Acoelomates do not have a body cavity, whereas, pseudocoelomates have a body cavity. Thus, the statement (b) is false.
