Which of the following characteristics is typical of the phylum Arthropoda?
Radial symmetry
Closed circulatory system
Endoskeleton made of bones
Presence of a segmented body
Spiegazione
Arthropods are characterized by the presence of a segmented body. This is a key characteristic of the phylum Arthropoda, which includes insects, spiders, and crustaceans. The other options are incorrect. Arthropods do not exhibit radial symmetry, they have an open circulatory system, and their exoskeleton is made of chitin, not bones.
