  1. PAP Biology Warm Up • Work on completing “A Bear Branch in the Tree of Life” Activity

  2. Objective • We will……review natural selection and evolution for tomorrows test.

  3. Question #1 • What level of organization is effected by natural selection?

  4. Question #2 • What type of evidence for evolution is to the right? • What determines relatedness?

  5. Question #3 • What could cause a quick change like you see in punctuated equilibrium?

  6. Question #4 • What can you tell me about the alleles for pea color from the Punnett square to the right? • What is it called when a genotype is AA? What about Aa?

  7. Question #5 • Which animal(s) is most closely related to the seal? • Which animal(s) is the most distantly related to the seal?

  8. Question #6 • What evidence for evolution use transitional forms? • Where would you find this evidence?

  9. Question #7 • What type of evidence for evolution is the picture to the right? • Why is it evidence for common ancestry?

  10. Question #8 • What is a gene pool? • When new genetic information is added to a gene pool we call this ______________. • Why could this be a positive occurence?

  11. Question #9 • Which organism would have the least difference with the green spotted puffer fish?

  12. Question #10 • What does the term resistant mean? • If a species of bacteria become resistant to medicine over time what is the term to describe this occurrence?

  13. Question #11 • What is the picture to the right? • What is the significance of the picture to the right with evolution?

  14. Question #12 • Freckles are a dominant trait over not having freckles. If the father is heterozygous for freckles and the mother is homozygous recessive then what is the genotypic ratio of their children?

  15. Question #13 • What is unique about the gametes produced in meiosis? • Why is this necessary?

  16. Question #14 • The monarch butterfly does not taste good to birds, birds like the flavor of viceroys. • What would be a reason that the viceroy mimics the monarch?

  17. Question #15 • What is the difference between transcription and translation?

  18. Question #16 • What could be a reason that the birds beak changed? • What do we call this?

  19. Question #17 • What is it called when an organism cannot recognize their own species?

  20. Question #18 • What type of reproductive isolation is causing the genetic drift in the salamander?

  21. Question #19 • Why is mercury a bigger danger to humans than the small fish? • What is the term used for this occurrence?

  22. Question #20 • What does a natural occurrences like a hurricane do to an ecosystem? • What is the term used to describe this stage?

  23. Question #21 • Likeness in structure between parts of different organisms which are evidence of common ancestry are called _____________.

  24. Question #22 • What theory explains the origin of chloroplasts and mitochondria in eukaryotic cells?

  25. Question #23 • Heritable structures or behaviors that an organisms possesses that allow it to more efficiently use its environment are __________________.

  26. Question #24 • As creatures become adapted to a particular environment, natural selection can cause a decrease in genetic diversity through out the population. This type of natural selection is __________________.

  27. Question #25 • Structures that have reduced in size because they no longer serve an important function are called ____________.

  28. Closure • I will ….create a plan to study for the Unit 9: Evolution Test.
