What is paleontology? -Paleontology is the study of the history of life and its meaning. It is a four-dimensional science (three spatial dimensions plus time) -Paleontology is an eclectic field that draws on many other disciplines, including, but not limited to geology, developmental biology, physics, and chemistry -Paleontologists focus on extinct organisms but we also study extant (present day) ones too What are fossils? -Fossils are preserved remains of organisms from the remote pa...

Geology 1113 Exam #2 Questions With Answers Match the relative dating principles with the correct definition: Superposition The oldest is on the bottom, the youngest on top A mammoth frozen in the Arctic tundra of Siberia would be an example of which type of fossilization? Mummification The fossil record is biased toward preserving organisms with hard parts. True In cast and mold fossilization, the cast is the hollow space in the rock that subsequently becomes filled with mine...

How does the fossil record reveal information about evolutionary changes? - Species change over time, and all organisms descended from a single common ancestor. What features make Tiktaalik a transitional fossil, and role do these types of fossils have in the fossil record? - Tiktaalik splits the difference of what you think of as a fish and a limbed animal. These fossils show how organisms evolved from water to land. What can anatomy and DNA reveal about evolution? - DNA shows the amount o...

Cognition: CORRECT ANSWER The mental act or process by which knowledge is acquired, including perception, intuition, and reasoning. Cognitive processes: CORRECT ANSWER Needed to internalize language rules and vocabulary in L2: - memorization; - categorization; and - generalization [categorize and generalize vocabulary]. Metacognition: CORRECT ANSWER An educational process that incorporates knowledge about one's abilities; the demands of given tasks, and potentially effective learning s...

Fossils Remains of organisms chemically changed into rock Taphonomy Study of what happens to an organism's remains after death. Describes circumstances for fossilization, how they got to where they are. Where are fossils usually found? In sedimentary or volcanic rock. Fossils are most commonly found in sedimentary rock (deposit of sediments) Fossils can also be found in ash from Volcanic activity Sometimes vestiges of ____ can be found within fossils DNA Chemical segments of bone can al...

what animals must do? - - Mechanism for excreting waste - Mechanism for development and growth - Energy input Disadvantage of multicellularity - Need special cell/cell connections Need for cell/cell communication Need system for distribution of nutrients What traits to animals share? - Eukaryotic, heterotrophic, able to move Why is the fossil record incomplete? - Needs to die near water, fossilization process needs to be in a situation where there's no oxygen present, rapidly covered in...
