Question

1. living oceans: classification

which of the following do echinoderms have? select all that apply.
radial symmetry
coelom
tissues
segmentation

Explanation:

• Radial Symmetry: As shown in the diagram, the trait "Radial Symmetry" is associated with Echinoderms.
• Coelom: Echinoderms are on the "Coelom" side of the evolutionary tree, meaning they have a coelom.
• Tissues: Since Echinoderms are more complex than Sponges (which are at the "Multicellular" level before "Tissues" in the tree), they have tissues.
• Segmentation: The trait "Segmentation" is associated with Annelids and Arthropods, not Echinoderms.

Answer:

• Radial Symmetry
• Coelom
• Tissues
