Which of the following statements about deuterostomes is false?
Answer:
Deuterostomes are a group of animals that includes vertebrates like fish, birds, reptiles, amphibians, and mammals, as well as some invertebrates like sea stars and sea urchins. In deuterostomes, the blastopore becomes the anus during embryonic development. This is a defining characteristic of deuterostomes, setting them apart from protostomes where the blastopore becomes the mouth.
One of the typical false statements about deuterostomes is that they do not exhibit radial symmetry. In reality, deuterostomes typically exhibit bilateral symmetry, where the right and left sides of the organism are mirror images of each other. Radial symmetry, on the other hand, is usually found in animals like cnidarians (e.g., jellyfish) and echinoderms (e.g., sea stars), which are not part of the deuterostome group. Therefore, the statement that deuterostomes exhibit radial symmetry is false.
