Question

Vertebrates and tunicates share which of the following?

A) jaws adapted for feeding.
B) a high degree of cephalization.
C) the formation of structures from the neural crest.
D) an endoskeleton that includes a skull.
E) a notochord and a dorsal, hollow nerve cord.

Answer 1

Vertebrates and tunicates share a notochord and a dorsal, hollow nerve cord.

Step-by-step explanation:

Vertebrates and tunicates share the following characteristic features: a notochord and a dorsal, hollow nerve cord. These two features are present in both vertebrates and tunicates at some stage of their life cycles. The notochord is a flexible rod-like structure that provides support, while the hollow nerve cord runs along the dorsal side of the animal and ultimately develops into the central nervous system. Examples of vertebrates include fish, birds, mammals, and reptiles, while tunicates are marine invertebrates that filter feed on plankton.
