Oceans have suspension feeders; terrestrial environments do not. This is most likely because of 3. Sedimentologists have determined that traces of organisms can be used to determine ancient water depth, termed paleobathymetry. The Skolithos assemblage (burrows) is found in intertidal environments; the Cruziana and Nereites assemblages (invertebrate trails) are found further offshore. These assemblages represent 4. New species arise from preexisting ones as a result of ? acting on ?. struggle for existence 5. Divergent boundaries would produce which of the following rock types? A.rhyolite B.eclogite C.basalt D.andesite E.peridotite 6. Adaptive Radiation pertains to the ? of species. A.origin B.extinction 7. Plesiosaurs are Triassic- to Cretaceous-age aquatic reptiles (these are what the Loch Ness monster is supposed to be). From studies of bone shape and position of muscle attachments, it has been determined that they moved their flippers in the same manner that birds move their wings during flight. The discovery that plesiosaurs swam by means of subaqueous flight was determined primarily by studies of 8. Temperate biomes typically have ? species diversity than tropical biomes. difference in species diversity between temperate and tropical biomes 9. Within the Upper Jurassic of Germany, fish and ichthyosaur (dolphin-like reptile) fossils are preserved by which the outline of the body may be discerned as a dark film. This type of fossil preservation is termed 10.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
