turning a new leaf think about how your ideas about classifying organisms have grown or changed since the beginning of the lesson. list as many new key ideas or facts as you can from the lesson.

Explanation:

To distinguish arachnids from insects, we look for characteristics that are unique to one group. Segmented body and jointed legs are common to both (so options A, C, D which include jointed legs - a shared trait - can be partially evaluated). Antennae are only in insects, simple eyes only in arachnids, compound eyes only in insects. Option B has antennae (insect - specific), simple eyes (arachnid - specific), compound eyes (insect - specific) which can help in distinguishing.

Answer:

B. antennae, simple eyes, compound eyes
