- Hello can someone help me with 2 question for my biology class. I really need very clear and short answerat least 2-3 sentences for this 2 question, thats not copied from google.Thank you 1)What does it mean to be eumetazoan? 2)Which animal phylum has bilateral symmetry only in its larval form, and metamorphoses into an adult form with a unique type of radial symmetry?36. flatworms have non-ciliated syncytial tegument true or false28. these are major evolutionary transformations in animals, except a. tube within a tube plan b. eucoelomate body plan c. asymmetry d. multicellularity
- Question:- 2.How might gill bacteria be important for survival in certain lamellibranch bivalves?Question:- 1.How is morphology related to food collection in protobranch and lamellibranch subclasses of bivalves?34.Though most gastropods are grazing forms , some are Sessile benthos . Select one : True False
- How do terrestrial arthropods of the subphylum Hexapoda impact the world’s food supply? Provide at least two positive and two negative effects.Crustaceans are ecdysozoans nematodes arachnids parazoansQUESTION 3: What do the words acoelomate, pseudocoelomate, and coelomate mean? What is the evolutionary trend between these three categories?
- question about ANNELIDS What was the significance of segmentation and the presence of true coelom in their evolution and adaptation?Question 7 Schistosoma mansoni and Clonorchis sinensis are classified taxonomically to which class ? Trematode Cestode Nematode Filaria Question 8 What is the Helminth species that DOES NOT belong to Nematode? Group of answer choices Enterobius vermiculares Necator americanus Taenia saginata Ascaris lumbricoides Question 9 Of the Helminths studied in class, which one has a snail as an intermediate host? Clonorchis sinensis and Schistosoma mansoni Schistosoma mansoni and Taenia solium Taenia saginata and Clonorchis sinensis Ascaris lumbricoides and Necator americanusWhy don't protists (eg. sponges) need circulatory systems? Question 12 options: None of their cells are in contact with their externl environment so that waste can not diffuse out of their bodies. All of their cells are in contact with their external environment so that nutrients and oygen can diffuse into cells. This is a misleading question because all animals have circulatory systems. They are such simple animals that they don't need oxygen.
