Is it more beneficial for Neodermata to have one host or two hosts?
Neodermatahas two classes: class Trematoda and class Monogenea. Class Trematoda has the subclass Digenea, which has organisms that live through at least two different hosts. An example of this is Fasciola hepatica, the sheep's liver fluke. Class Monogenea has organisms that only need to live through one host.
Is it better to have a simple or complex life cycle? Which lives longer? Has more energy? Does more damage or good?
For each of the following classes of Arthropods, identify a feature unique to the class and at least 2 organisms that belong to the class:
Insecta
Crustacea
Chelicerata
Diplopoda
2. State the function of the following parts of the genus Romalea (grasshopper):
antenna,
tympanum,
spiracles,
ovipositor (female),
gastric caeca,
malphigian tubules,
tracheae,
air sacs .
Describe the life cycle of the human hookworm? How was john D. Rockfeller and southern US commerce involved in this story?how far away from a pile of poop can a hookworm crawl before dying? How did Rockfeller's medical investigators eradicate the hookworm problem, as well as many excrment- related parasitic disease?

- Your colleague is studying a newly discovered organism. She is becoming increasingly convinced that the organism is an arthropod. You find that you must respectfully disagree when you note that the organism has a set of distinctly non-arthropod characteristics. The features that cause you to exclude the organism from the arthropod grouping are antennae, six legs, and mandibles. pseudocoel, closed circulatory system, and ventral heart. Malpighian tubules, ommatidia, and tagmata. jointed legs, ecdysis, and an exoskeleton. compound eyes, book lungs, and a hemocoel.arrow_forwarddo any nematodes have similar adaptations due to their needs being met by their hosts? I know that nematodes are parasitic and not mutually beneficial, but they are still symbionts and perhaps have evolved to no longer require some components of basic anatomy in result of their needs being met by their host. please cite sourcesarrow_forwardWhy are parasitic infections of nematodes still common despite our understanding of their biology? Explain if these infections are due to the adaptations of these parasitic helminths or our lapses in their control and eradication.arrow_forward

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.
