Question
1. Which is a characteristic of chordates?all chordates have a backboneall chordates live on landall chordates have a notochordAll chordates breathe air
Solution
The correct answer is "all chordates have a notochord". This is a defining characteristic of chordates, which include a wide range of organisms, including humans. The notochord is a flexible rod that supports the body of a developing embryo. While many chordates do develop a backbone, not all do. Similarly, while many chordates live on land and breathe air, not all do. For example, fish are chordates that live in water and breathe through gills.
