Question

question 5
the phylum chordata includes several subgroups of organisms. to which of these subgroups would humans belong?
vertebrates
cephalochordates
urochordates
monotremes

Explanation:

• Vertebrates: Vertebrates are a subgroup of Chordata. They have a backbone (vertebral column) which humans possess.
• Cephalochordates: These are small, fish - like marine animals (e.g., lancelets) without a true backbone.
• Urochordates: Also known as tunicates, they are sessile (adult form) marine animals with a notochord only in the larval stage.
• Monotremes: These are a group of mammals (e.g., platypus) but they are a subclass within mammals (which are vertebrates), not a subgroup of Chordata in the same sense as vertebrates, cephalochordates, and urochordates.

Answer:

Vertebrates
