True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
Do pharyngeal slits disappear before birth in all chordates?
No, pharyngeal slits do not disappear before birth in all chordates. In some chordates, such as fish, these slits persist throughout their life and play a role in respiration and feeding. In other chordates, such as mammals, the pharyngeal slits do not persist through adulthood but are present during embryonic development.
Difference between chordates and vertebrates?
Chordates are animals that possess a notochord at some stage of their development, while vertebrates are a subgroup of chordates that have a backbone or spinal column made of vertebrae. Therefore, all vertebrates are chordates, but not all chordates are vertebrates.
