Question

7. True/False: Some invertebrates are also chordates.

Answer 1

True
Vertebrates are all chordates which have a backbone. The other two subphyla are invertebrate chordates that lack a backbone. Members of the subphylum Urochordata are tunicates (also called sea squirts). Members of the subphylum Cephalochordata are lancelets.

Answer 2

This is actually true. CHordates include the marine invertebrates from the subphylums Tunicata and Cephalochordata.
