Answer: In lower layers of rock. NEXT QUESTION Geologic Time - 200 Of the following, which one was least likely to be found in the earth’s early atmosphere? Methane-CH4 Oxygen Gas-O2 Answer: Water Vapor-H20 Oxygen Gas Ammonia-NH3 NEXT QUESTION 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 Geologic Time - 400 What organism was most helpful in creating an environment on land that was Answer: habitable? Photosynthetic bacteria. NEXT QUESTION Geologic Time - 500 How are radioactive isotopes used to determine the age of material ? 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 Evidence - 100 The similarity in early development of organisms represents which type of evidence? NEXT QUESTION Answer: Embryology Evidence - 200 What type of evidence is shown in this picture? Answer: Vestigial Structures NEXT QUESTION Evidence - 300 Looking at amino acid sequences to Answer: compare Biochemical. evolutionary relationships is what type of evidence? NEXT QUESTION Evidence - 400 Anatomical structures that have a similar function, but did not evolve from a recent ancestor are called what? Answer: Analogous structures NEXT QUESTION Evidence - 500 List three types of Answer: morphological Vestigial, evidence for Homologous, and evolution and one example of each. Analogous structures. Examples will vary. NEXT QUESTION The theories of life - 100 The idea that living things could arise from non-living material is called what? Answer: Spontaneous generation. NEXT QUESTION The theories of life -200 What is endosymbiosis? Answer: When a prokaryotic cell with heterotrophic characteristics engulfed(endo) an autotrophic cell. They lived in harmony, (symbiosis). NEXT QUESTION The theories of life - 300 How was Louis Pasteur’s experiment to disprove spontaneous generation different from either Francesco Redi’s or Lazarro Spallanzani’s? 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 The theories of life - 400 What did Miller and Urey’s experiment demonstrate? Answer: That early atmospheric gases could have formed organic compounds. NEXT QUESTION The theories of life - 500 Define natural selection Answer: Organisms that are more adapted to an environment will survive and reproduce to pass on those traits to their offspring. NEXT QUESTION Natural Selection - 100 Will evolution occur if organisms mate randomly? Explain your answer. Answer: No. There is no selection for the better trait. Unwanted traits, such as poor health, may be inherited. NEXT QUESTION Natural Selection - 200 Why will a small population evolve faster than a larger population? NEXT QUESTION Answer: It takes more time to see genetic changes in the larger population. Natural Selection - 300 The change in the allele frequency of a population over time due to random chance is called what? Answer: Genetic drift NEXT QUESTION Natural Selection - 400 Answer: The introduction of new alleles into a population is called what? Gene Flow or immigration. NEXT QUESTION Natural Selection - 500 Answer: List two of the four conditions 1. Over production of offspring needed for natural 2. Variation within a species exists selection to take 3. Organism will compete for place. limited resources. NEXT QUESTION 4. Organisms who gain the resource, based on inherited traits, will survive and pass them on All of the above -100 The major source of genetic variation. Answer: Mutations NEXT QUESTION All of the above - 200 The ability of an Answer: organism to survive and Fitness reproduce is called an organism’s what? NEXT QUESTION All of the above - 300 This is one way in which scientists can determine the age of once living organisms. NEXT QUESTION Answer: Radioactive dating. All of the above - 400 Calculate the age of a Answer: sample containing 150,000 years thorium -230(whose half life is 75,000 years) after ¾ of the sample has decayed. NEXT QUESTION All of the above - 500 The process by which unrelated organisms come to look like one another is called What? Answer: Convergent evolution. NEXT QUESTION First life forms - 100 What is the significance of the experiment Urey & Miller performed? Answer: They were able to create organic compounds from inorganic compounds in conditions that replicated Earth’s early atmosphere. NEXT QUESTION 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 First life forms - 300 • What are • Prokaryotic three inferred • Heterotrophic characteristic • Anaerobic of the first life form? NEXT QUESTION First life forms - 400 What is the difference between chemosynthesis and photosynthesis? • Answer:Both are capable of creating organic compounds from inorganic one, but chemosynthesis uses chemicals(H2S) instead of sunlight. NEXT QUESTION 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
