3. Geologic Time - 200 Of the following, which one was least likely to be found in the earth’s early atmosphere? Methane-CH 4 Oxygen Gas-O 2 Water Vapor-H 2 0 Ammonia-NH 3 Answer: Oxygen Gas NEXT QUESTION

4. Geologic Time - 300 If 1.0 g of a radioactive isotope had a half life of 1 billion years, how much would be left after 3 billion years? Answer: 0.125 g NEXT QUESTION

5. Geologic Time - 400 What organism was most helpful in creating an environment on land that was habitable? Answer: Photosynthetic bacteria. NEXT QUESTION

6. Geologic Time - 500 Answer: Radioactive isotopes decay at a specific rate. The rate is known as its half-life. This is the amount of time it takes for ½ of the material to decay. NEXT QUESTION How are radioactive isotopes used to determine the age of material ?

7. Evidence - 100 Answer: Embryology NEXT QUESTION The similarity in early development of organisms represents which type of evidence?

8. Evidence - 200 Answer: Vestigial Structures NEXT QUESTION What type of evidence is shown in this picture?

9. Evidence - 300 Answer: Biochemical. NEXT QUESTION Looking at amino acid sequences to compare evolutionary relationships is what type of evidence?

10. Evidence - 400 Answer: Analogous structures NEXT QUESTION Anatomical structures that have a similar function, but did not evolve from a recent ancestor are called what?

11. Evidence - 500 Answer: Vestigial, Homologous, and Analogous structures. Examples will vary. NEXT QUESTION List three types of morphological evidence for evolution and one example of each.

12. The theories of life - 100 Answer: Spontaneous generation. NEXT QUESTION The idea that living things could arise from non-living material is called what?

13. The theories of life -200 Answer: When a prokaryotic cell with heterotrophic characteristics engulfed(endo) an autotrophic cell. They lived in harmony, (symbiosis). NEXT QUESTION What is endosymbiosis?

14. The theories of life - 300 Answer: Louis had an experimental flask that was open to the air containing the “Vital Force”with a swan neck. The broth did not support life. NEXT QUESTION How was Louis Pasteur’s experiment to disprove spontaneous generation different from either Francesco Redi’s or Lazarro Spallanzani’s?

15. The theories of life - 400 Answer: That early atmospheric gases could have formed organic compounds. NEXT QUESTION What did Miller and Urey’s experiment demonstrate?

16. The theories of life - 500 Answer: Organisms that are more adapted to an environment will survive and reproduce to pass on those traits to their offspring. NEXT QUESTION Define natural selection

17. Natural Selection - 100 Answer: No. There is no selection for the better trait. Unwanted traits, such as poor health, may be inherited. NEXT QUESTION Will evolution occur if organisms mate randomly? Explain your answer.

18. Natural Selection - 200 Answer: It takes more time to see genetic changes in the larger population. NEXT QUESTION Why will a small population evolve faster than a larger population?

19. Natural Selection - 300 Answer: Genetic drift NEXT QUESTION The change in the allele frequency of a population over time due to random chance is called what?

20. Natural Selection - 400 Answer: Gene Flow or immigration. NEXT QUESTION The introduction of new alleles into a population is called what?

21. Natural Selection - 500 Answer: 1.Over production of offspring 2.Variation within a species exists 3.Organism will compete for limited resources. 4.Organisms who gain the resource, based on inherited traits, will survive and pass them on NEXT QUESTION List two of the four conditions needed for natural selection to take place.

22. All of the above -100 Answer: Mutations NEXT QUESTION The major source of genetic variation.

23. All of the above - 200 Answer: Fitness NEXT QUESTION The ability of an organism to survive and reproduce is called an organism’s what?

24. All of the above - 300 Answer: Radioactive dating. NEXT QUESTION This is one way in which scientists can determine the age of once living organisms.

25. All of the above - 400 Answer: 150,000 years NEXT QUESTION Calculate the age of a sample containing thorium -230(whose half life is 75,000 years) after ¾ of the sample has decayed.

26. All of the above - 500 Answer: Convergent evolution. NEXT QUESTION The process by which unrelated organisms come to look like one another is called What?

27. First life forms - 100 Answer: They were able to create organic compounds from inorganic compounds in conditions that replicated Earth’s early atmosphere. NEXT QUESTION What is the significance of the experiment Urey & Miller performed?

28. First life forms - 200 What is the significance of coacervates and microspheres? Cell like structures, with some of life’s characteristics were created without genetic information. Microsphere= protein based membranes Coacervates= amino acids and carbohydraes NEXT QUESTION

29. First life forms - 300 What are three inferred characteristic of the first life form? Prokaryotic Heterotrophic Anaerobic NEXT QUESTION

30. First life forms - 400 Answer:Both are capable of creating organic compounds from inorganic one, but chemosynthesis uses chemicals(H 2 S) instead of sunlight. NEXT QUESTION What is the difference between chemosynthesis and photosynthesis?

31. First life forms - 500 What role did cyanobacteria have in changing the early Earth’s atmosphere? Answer: It is an autotrophic algae. Its production of oxygen was helpful in creating the ozone shield in the stratosphere. NEXT QUESTION
