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
