23. 12. A certain organism in the tundra changes its sleep patterns during the slightly warmer summer months. Which of these describes this change? Phenotypic alteration Structural adaptation Behavioral adaptation Physiological adaptation

24. 13. Walking through the woods in the middle of the winter, a hiker notices that most of the trees still have their leaves attached. Which biome is the hiker most likely walking through? Coniferous Forest Deciduous Forest Tundra Tropical Rainforest

25. 14. The picture at the right shows a Fennec fox, the smallest of the world’s foxes. In which biome is this organism most likely found? Tundra Coniferous Forest Grassland Desert

26. 15. The skull of an organism is shown at the right. Based on the shape of its teeth lack of fur, in which biome is this organism found? Tundra Coniferous Forest Grassland Desert

27. 16. Crassulacean acid metabolism (CAM) is a type of photosynthesis. A plant using CAM takes in carbon dioxide (CO2) at nighttime, when it is cooler. The plant changes the CO2 into an acid. During the daytime, the plant changes the acid into carbohydrates, without losing water to the warm air. In which environment are such plants best adapted for survival? Low-altitude, because the air pressure is greater closer to sea level Desert, because plants living in the desert have little water available High-altitude, because the night air is cooler in alpine zones of mountains Aquatic, because plants living in water need more carbohydrates to avoid drowning

28. 17. Which table shows adaptations that allow organisms to survive in a marshy wetland environment? C. A. B. D.

29. 18. A new organism is discovered on the floor of a forest. Its picture is shown below. Which of these is most likely the forest where it was found? Coniferous Forest Taiga Deciduous Forest Tropical Rainforest

30. 19. A student is determining which biome an area is in. He takes a picture (shown below) while walking in the area. Which of these describes the biome? Coniferous Forest Taiga Deciduous Forest Tropical Rainforest

31. 20. An organism has thick blubber and webbed feet. Which of these describes the environment in which it most likely lives? Desert Tundra Cold marine Taiga

32. 21. A new organism is found living in a deciduous forest. Which of these is NOT an adaptation that would be seen in this organism? Fur that changes thickness Sharp teeth Fur that can lighten and darken Gills that help it get oxygen

33. 22. A certain white insect is camouflaged by the lightly colored trees it lives on. What would happen if pollution darkened these trees? The number of insects would decrease because they wouldn’t have any food. The number of insects would decrease because predators would be able to find them easily. The number of insects would increase because they could live on all the other trees. The number of insects would increase because they could use the pollution as a food source.

34. 23. Who created the theory of evolution and natural selection? Rudolf Virchow Charles Darwin Joseph Kralik Timothy Riggins

35. 24. Which term best describes a specially developed characteristic that enables an organism to live in a specific environment? adaptations natural selection Survival of the fittest variations

36. 25. What will likely happen to a species that lacks the variation necessary to adapt to a changing environment? It will undergo many genetic mutations. It will become extinct over time. It will begin to reproduce asexually. It will become resistant to disease.

37. 26. Which of these supports the theory of natural selection? All organisms produce more offspring than can survive. Organisms live in harmony with one another despite limited resources. Organisms with favorable traits are more likely to die. Over time advantageous traits will be found in more of the population.

38. 27. The Bird of Paradise is a species that has been observed in the jungles of New Guinea. In an attempt to attract females, the males shake their bodies and sometimes hang upside down to show off their bright colors and long feathers. Females generally chose to mate with the “showiest” males. Which concept is supported by these observations? An organism’s individual physical growth can be dependent on behaviors of the population. Asexual reproduction can lead to demanding courtship displays to attract mates for diversity. Behaviors that lead to reproductive success have evolved in species. Strange and vibrant courtship behaviors lead to extinction of particular species.

39. 28. All of the rabbits in the ecosystem are killed by hunters. Which of these populations would decrease in size because of this? Shrubs Squirrels Weasels Foxes

40. 29. An herbicide kills all the shrubs in this ecosystem. Which of these populations would be most impacted? Squirrel Caterpillar Thrush Rabbit

41. 30. A decrease in the number of hawks, foxes, and weasels is seen. A decrease in which of these populations most likely cause this? Thrush Mouse Rabbit Squirrel

42. 31. Overfishing of Striped Bass has depleted their numbers. Which of these explains the impact on the Blue Crab population? The population will decrease because of less food. The population will decrease because of less predation. The population will increase because of less food. The population will increase because of less predation.

43. 32. A scientist discovers that Algae are beginning to receive more sunlight. How will this impact the Horseshoe Crab population? More sunlight will lead to increased algae growth which will decrease the number of horseshoe crabs. More sunlight will lead to increased algae growth which will increase the number of horseshoe crabs. More sunlight will lead to decreased algae growth which will decrease the number of horseshoe crabs. More sunlight will lead to decreased algae growth which will increase the number of horseshoe crabs.
