Coelenterate
A)an animal having no backbone
B)an invertebrate animal that has tentacles around its mouth
C)an ocean invertebrate having spiny skin
D)an invertebrate animal with jointed legs and an exoskeleton
E)an outer covering that supports the soft inner tissues in an arthropod
B)an invertebrate animal that has tentacles around its mouth
The correct answer is B) an invertebrate animal that has tentacles around its mouth.
To figure out the correct answer, we can break down the word "coelenterate" and understand its meaning. The term "coelenterate" is a commonly used name for the phylum Cnidaria, which includes animals such as jellyfish, sea anemones, and corals.
To identify the characteristics of a coelenterate, we can focus on the definition options provided:
A) an animal having no backbone - This definition describes all invertebrate animals, not just coelenterates.
B) an invertebrate animal that has tentacles around its mouth - This is the correct definition for coelenterates, as animals in this phylum have tentacles surrounding their mouth.
C) an ocean invertebrate having spiny skin - This definition does not accurately describe coelenterates, as they typically do not have spiny skin.
D) an invertebrate animal with jointed legs and an exoskeleton - This definition is incorrect, as coelenterates do not have jointed legs or an exoskeleton. Jointed legs and an exoskeleton are characteristics of arthropods.
E) an outer covering that supports the soft inner tissues in an arthropod - This definition is specific to arthropods and does not apply to coelenterates.
Therefore, the correct answer is B) an invertebrate animal that has tentacles around its mouth.
