ANSWERS

1. C.-Echinderms are deuterostomes and triploblastic
2. B- Annelida are covered by a cuticle.
3. B- Bacterial cell walls contain peptidoglycan
4. D- Eutherians (commonly called placental mammals) have a true placenta.
5. Annelids including earthworms and leeches.
6. Archaea are extremophiles.
7. Platyhelminthes are acoelomates
8. E-Uric acid is the least toxic form of nitrogen waste and takes the least amount of water to dilute
(Excreting uric acid conserves water)
9. Bacteria and Archaea have all of these in common except C. Only Archaea have a few gene introns.
10. All are vertebrates except starfish.
