What type of symmetry is seen in the roundworm?
Does it exhibit cephalization?
Ascaris is a parasite that swims constantly in human intestines. What structure protects the nematode from being digested?
View the Trichinella slide. Trichinella is also a parasite. It can infect humans as well as other mammals like pigs, bears, and rodents. If untreated, it can lead to death.What mammal tissue does this roundworm infect?Draw a picture below of the Trichinella as viewed under the microscope.
Although not mentioned on the website, if available view the live vinegar eel specimens. If there are no live specimens available, check out this you tube video instead: https://www.youtube.com/watch?v=UnjwvtFvyeQDescribe the movement of the vinegar eels.Do they have a complete or incomplete digestive system?
Compare and contrast the body coverings of a free-living turbellarian, a monogenaen fluke, a cestode, and a nematode. Which problems does each solve or create? Be sure to consider locomotion, permeability, ciliation, and habitat, and to think of the entire life cycle.
Mollusca (clams, abalone, nudibranchs, snails, squid, octopi,
etc).
Unifying features include shell, mantle, radula, foot, visceral
mass
Which classes show a loss of the shell. How does the shell
benefit an organism, how does the loss of the shell benefit other
members of this phylum?
Distinguish between polyplacophora, bivalva, gastropoda, and
chephalopoda
