Question

Members of the class Arachnida have
A)a cephalothorax and abdomen.
B)antennae.
C)mandibles.
D)five pairs of walking legs.
E)All of the choices are arachnid features.

Accepted Answer

Arachnids, including spiders, scorpions, ticks, and mites, have a cephalothorax and abdomen, which are two distinct body segments. They do not have antennae or mandibles, and typically have four pairs of legs (totalling 8 legs) rather than five. Therefore, only choice A is accurate.
