Question

Quizplus · Accepted Answer

Arthropods are characterized by segmented bodies, tough exoskeletons made of chitin, and jointed appendages. These features allow arthropods to have a high degree of mobility and flexibility in their movements. Although some arthropods, such as crustaceans, have fused bodies, this is not a characteristic of all arthropods. And while some arthropods, such as spiders, have no exoskeleton, this is also not a general characteristic of the entire phylum. Therefore, the best choice is D, which lists all the key characteristics of arthropods.
