Geologic Time Answer: In lower layers of rock. NEXT QUESTION Older fossils would be found where in relation to younger fossils?

Geologic Time 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

Geologic Time 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: g NEXT QUESTION

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

Geologic Time 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 ?

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

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

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

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

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

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

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?

The theories of life 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?

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

The theories of life 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

Natural Selection 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.

Natural Selection 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?

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

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

Natural Selection 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.

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

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

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

All of the above 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.

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

First life forms 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?

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

First life forms 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?

First life forms 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
