Question

animals with segmented bodies include organisms like worms, beetles, and butterflies. scientists study the morphological variation among these organisms to determine their evolutionary relationships. a cladogram shows the relationships among groups of animals with segmented bodies.

relationships among segmented animals

the following question has two parts. first, answer part a. then, answer part b.

part a
select the boxes to show each trait possessed by each group of segmented animals.

part b
select the two organisms that are most closely related.

Explanation:

For Part A, we use the cladogram to determine traits. Organisms with wings have this trait indicated in the appropriate boxes, and so on for other traits based on the cladogram's hierarchy. For Part B, organisms that share more recent common - ancestors in the cladogram are more closely related.

Answer:

Part A:
Beetles: Wings (yes), Exoskeletons (yes), Wing sheaths (yes), Folding wings (yes), Coiled mouthparts (no)
Bristletails: Wings (no), Exoskeletons (yes), Wing sheaths (no), Folding wings (no), Coiled mouthparts (no)
Mayflies: Wings (yes), Exoskeletons (yes), Wing sheaths (yes), Folding wings (no), Coiled mouthparts (no)
Moths: Wings (yes), Exoskeletons (yes), Wing sheaths (yes), Folding wings (yes), Coiled mouthparts (yes)
Roaches: Wings (yes), Exoskeletons (yes), Wing sheaths (yes), Folding wings (yes), Coiled mouthparts (no)
Velvet Worms: Wings (no), Exoskeletons (no), Wing sheaths (no), Folding wings (no), Coiled mouthparts (no)
Part B: Beetles and Roaches (as they share more recent common - ancestor compared to others in the cladogram)
