(02.04 LC) Which of these is a piece of evidence supporting the theory of evolution? (4 points) Emus and ostriches are similar and exist in different geographical locations. Emus and ostriches are different names for the same animal. Emus, ostriches, and rheas are similar to the glyptodon. Ostriches resemble armadillos. 2. (02.04 MC) What have we learned from fossil evidence about evolution? (4 points) It is an abrupt change. The process is observable. It takes place during one lifetime only. The most complex traits are always selected. 3. (02.04 MC) Which description justifies why the theory of evolution is a theory and not a law? (4 points) Explains how organisms change in response to the environment Predicts which organism is best suited to the environment Supported by a small amount of empirical evidence With more evidence it will become a law 4. (02.04 MC)

The leopard uses its specialized coloration to hide in the tree while stalking its prey. Which type of adaptation does this describe? (4 points) Mimicry Chemical defense Camouflage Warning coloration 5. (02.02 MC) The graph shows the amount of pesticides and fertilizers detected in a pond ecosystem that had cricket frogs, alligators, and mosquitoes. (4 points) If the population of alligators and mosquitoes remains the same during this period, what is most likely going to happen to the population of cricket frogs over time? Increases as the habitat is increasingly polluted Decreases as the habitat is increasingly polluted Remains the same as prey population remains the same Remains the same as predator population remains the same 6. (02.03 LC) Which physical feature is evidence that supports the evolution of Earth due to volcanic eruptions? (4 points) Bryce Canyon Great Blue Hole, Belize Hawaiian Islands Wave Rock, Australia 7. (02.01 LC) Which of these is a harmful interaction? (4 points) Competition Mutualism Commensalism Symbiosis 8.

(02.03 LC) What discoveries has space technology helped scientists with? (4 points) Allows scientists to ignore prior evidence when creating new theories Allowed scientists to determine exactly how extinct organisms died Allows scientists to find all of the fossils buried deep inside Earth Allowed scientists to better identify the location of fossils and change prior scientific knowledge 9. (02.03 MC) While visiting Wave Rock in Australia, you observe streaks of minerals left behind on the landform from rainwater runoff. What natural process most likely caused the streaking? (4 points) Erosion Deposition Oxidation Weathering 10. (02.03 LC) A scientist studied four fossils of a marine mammal dating back to 50 million years, 45 million years, 40 million years, and 30 million years ago. Which fossil is most similar to the present-day mammal? (4 points) 30 million years 40 million years 45 million years 50 million years 11. (02.02 LC) Which of these serves as a reference for comparison during a scientific investigation? (4 points) Outcome variable (dependent variable) Test variable (independent variable) Control group Hypothesis 12. (02.01 LC)

What type of relationship exists between two organisms when one organism benefits from the relationship and the other organism becomes prey? (4 points) Commensalism Competition Mutualism Predation 13. (02.02 MC) Which factors are most likely to limit population growth in the Atacama desert? (4 points) High moisture and lack of sunlight High moisture and excessive sunlight High temperature and low precipitation High temperature and high precipitation 14. (02.02 MC) A scientist is designing an investigation to study the impact of fungal disease on the population of mountain yellow-legged frog in a recreational nature park. What is most likely the outcome variable (dependent variable) for the study? (4 points) Frog population Fish population Disease-controlled habitat Native habitat in natural setting 15. (02.04 MC) A scientist is designing an investigation to study which color of peppered moth would have a higher survival rate in his neighborhood. What is most likely the test variable (independent variable) in this investigation? (4 points) Neighborhood environment Survival rate Number of predators Colors of peppered moths 16. (02.04 MC) Turtle X has a hard, sharp beak with a short neck; and Turtle Y has no beak and has a very long neck. What is the correct typical diet for the two turtles? (4 points)

Turtle X and Turtle Y break nuts and dig for food on the ground. Turtle X and Turtle Y reach for food higher up on bushes and trees. Turtle X reaches for food higher up on bushes and trees; and Turtle Y breaks nuts and digs for food on the ground. Turtle X breaks nuts and digs for food on the ground; and Turtle Y reaches for food higher up on bushes and trees. 17. (02.02 HC) Wildflowers are plants that grow on the forest floor. During a study, a scientist observed that wildflowers began to bloom before the leaves appeared on the tall trees above them and stopped blooming once the trees were full of broad leaves which blocked the sunlight. Evaluate this observation and explain a limiting factor this is affecting the wildflowers on the forest floor.
