Question

question 8/10 ctenophore are considered more advanced than cnidaria. which of the following would support this idea? a. ctenophore have an anal pore for one way digestion b. ctenophore have a mesoglea with true muscle cells so may be triploblastic c. ctenophore have a nerve net d. both a and b e. all of the above

Explanation:

Ctenophores having an anal pore for one - way digestion (option A) is an advancement as it represents a more specialized digestive system compared to Cnidaria. Also, ctenophores having a mesoglea with true muscle cells and potentially being triploblastic (option B) shows a higher level of tissue and body - plan complexity. Nerve nets are present in both Cnidaria and ctenophores, so it doesn't support ctenophores being more advanced.

Answer:

D. Both A and B
