1 1.Amish people are required by their religion to only marry and have children with other Amish people.

2 1.Amish people are required by their religion to only marry and have children with other Amish people. NON RANDOM MATING (mates are chosen based on SPECIFIC characteristics)

3 2. The DNA sequence in a bird is changed from ATT CCG TTG to TTA CCG TTG which changes the beak shape from long and thin to short and fat.

4 2. The DNA sequence in a bird is changed from ATT CCG TTG to TTA CCG TTG which changes the beak shape from long and thin to short and fat. MUTATIONS (changes in DNA)

5 3.Peppered moths are eaten by birds. The moth color varies from light to dark. Light colored moths can blend in with a nearby species of tree. In the 1800s factories released large amounts of soot, which changed the tree color, so the birds were able to more easily find the lighter moths instead of the darker moths.

6 NATURAL SELECTION: THE CHANGE IN THE ENVIRONMENT FAVORS THE DARKER COLORED MOTH

7 4. Northern elephant seals were hunted almost to extinction by people in the 1890s. The remaining population has reduced genetic variation.

8 SMALL POPULATION: Specifically this is an example of THE BOTTLE NECK EFFECT BECAUSE A LARGE PART OF THE POPULATION HAS DIED

9 5. A lioness joins a new pride and has cubs with the male lion.

10 This is an example of GENE FLOW: Specifically IMMIGRATION *the lioness enters a new population and breeds

11 6. A small group of birds flies from the mainland to an island and starts a new colony. (The birds never return to the mainland.)

12 This is an example of Gene Flow: Specifically THE FOUNDER EFFECT since the birds are “starting a new cololny”

31 10. A population of giraffes inhabits an area filled with tall trees and vegetation that is located high off of the ground. Within the population of giraffes are individuals with short, medium, and long necks. Which of the individuals will leave behind the most offspring? ___________

33 11. Copy the following sentence with the correct answer choice. Natural selection happens (quickly/slowly) and occurs in (individuals/populations).

35 12. A brand of fire ant poison claims to kill all ants in two applications. The first application of the poison killed 74% of the fire ants. Three months later, the poison was reapplied but only killed 39% of the remaining fire ant population. Explain the decrease in the effectiveness of the ant poison.

36 12. A brand of fire ant poison claims to kill all ants in two applications. The first application of the poison killed 74% of the fire ants. Three months later, the poison was reapplied but only killed 39% of the remaining fire ant population. Explain the decrease in the effectiveness of the ant poison. The ants that survived the first poison passed on that trait to their offspring (natural selection).

37 13. Imagine that a small island holds a population of lizards that are all the same (have the same traits). Now imagine a strong storm sweeps some of the island lizards over to the mainland. On the mainland, there are new ecosystems for the island lizards to explore. In these new ecosystems, they meet new populations of lizards (with new traits) that they can now breed with. What might happen with regards to the variation that could be created within the population of island lizards? (more, less, no change)

41 18. Write a one sentence summary for the following passage. You are most likely aware that not every plant is adapted to survive in every ecosystem. Plants are specialists and thrive in environments that they are best adapted to, but could die in the wrong environment. A cactus would die in a wetland. A palm tree would freeze during a winter. ________________________________________ ________________________________________.

45 20. How is the organism in the picture adapted to its environment?

47 21. How is the organism in the picture adapted to its environment?

48 21. How is the organism in the picture adapted to its environment? Smell discourages predators, coloring discourages predators

49 22. Explain how humans caused wolves to evolve into dogs.

50 22. Explain how humans caused wolves to evolve into dogs. People only bred wolves with traits they wanted (cuteness, tameness, etc). Over many generations wolves evolved into dogs.

51 23. Explain the following graph as it relates to natural selection and evolution.

52 23. Explain the following graph as it relates to natural selection and evolution. Choosing only large or small fish to remove from the tank changes the gene pool, which changes the average size of the fish over time.

53 24. Define inherited variation

54 24. Define inherited variation children have different characteristics than their parents and each other.
