based on evolution)
Step by step
Solved in 5 steps
- Label the parts that are visible of these rotifers and acanthocephalans: 1. Rotifer from class Bdelloidea 2. Rotifer from class MonogonontaBased on an evolutionary perspective, do you think the present forms of cnidarians are the best forms of the group? Why or why not?Specifically, what are the importance of ctenophores and cnidarians to humans? Why do they need to be protected?
- a marine blue crab has ten pairs of jointed appendages, which include large claws called chelipeds to capture food, and eight walking appendages. Notice the differences in the structure of these 8 pairs. Compare the structures present in the first 3 pairs (modified as maxillipeds), and the last five pairs. What do you think are the main functions of the last five pairs? Crustaceans have biramous appendages. What structures are present only in the first pair? In the last pair? What do you think are the function of these structures?What disadvantages associated with having exoskeletons did arthropods have to overcome to allow natural selection to favor this trait? How did they circumvent these problems?what's the importance of morphology used as basis for classifying Cnidarians? does it have more weight than genetics?
- The evolutionary ancestry of acanthocephalans is particularly obscure. Describe some characters of acanthocephalans that make it surprising that they could be highly derived rotifers.this is dugesia Compare the body plan of Dugesia and cnidarians. Aside from differences in symmetry, what other innovative anatomical features did you observe in Dugesia that were not observed in cnidarians?All cnidarians have cnidoblasts, but not all cnidoblasts sting. What else could an ejecting thread do to capture a prey organism?
- Why does Phylum Nematomorpha only possess longitudinal muscles in their body? Explain.Echinodermata is the first phylum you have examined whose members possess true endoskeletons. What are some advantages that an endoskeleton provides?Cnidarians and ctenophores are considered diploblastic, but why might some biologists label them triploblastic?
