Question

all vertebrates are chordates but all chordates are not vertebrates​

Answer 1

Answer:

False

Explanation:

Chordates are the scientific classification group for animals with backbones while vertebrates is the common name for animals with backbones. All chordates are vertebrates and all vertebrates are chordates.

Answer 2

Answer:

• The characteristic features of the phylum, Chordata, include the presence of a notochord and paired pharyngeal gill slits.
• In sub-phylum Vertebrata, the notochord present in embryos gets replaced by a cartilaginous or bony vertebral column in adults.
• Thus, it can be said that all vertebrates are chordates but all chordates are not vertebrates.
