  11. #10. According to this simplified water cycle, the process of transpiration is the process that— • Releases water vapor from plants • Increases the rate of the water cycle • Speeds the evaporation of water • Causes photosynthesis in plants

  12. #11. In the graph, what is the population of deer at the carrying capacity of the environment? a. 30 b. 10 c. 50 d. 70

  13. #12. An experiment is designed to clear an oak-hickory forest and replant the area with pines. Which of the following species would be most threatened by this experiment? • Hooded warbler • Summer tanager • Cardinal • Field sparrow

  14. #13. The above chart shows vertebrate embryo development. Which of these would be least related to the others? a. 1 b. 2 c. 3 d. 4

  15. #14. Eutrophication of a lake occurs when a. Algal and bacterial populations grow quickly with nutrients being washed into waterways b. Photosynthesis organisms are limited c. The diversity of its species increase d. Oxygen levels in the water increase

  16. #15. Amoeba and paramecium belong to this kingdom: a. Eubacteria b. Fungi c. Protista d. Animalia

  17. #16. Scientists have discovered a new species of bird. Which would provide the BEST basis for classifying this species? a. Cell structure b. Habitat • Method of reproduction • DNA comparasion

  18. #17. Structures with no current biological function that are remnants of an organism’s evolutionary past are called a. Vestigial structures b. Analogous structures c. Homologous structures d. Fossil structures

  19. #18. Which of the following is a biotic factor that would affect the population of trout in a stream? a. Sunlight b. Water temperature c. Water level d. Predators

  20. #19. The digestion of pizza, the light reactions in photosynthesis, and the removal of a stain by laundry detergent all require ____, which are biological proteins that lower the activation energy for chemical reactions. a. Enzymes b. Antibiotics c. Carbohydrates d. Nucleic Acids

  22. #21. What process accounts for species diversity because it offers genetic variation? a. Mitosis b. Meiosis c. Predation d. Symbiosis

  23. #22. Which two organisms are MOST closely related? a. Birds & Snakes b. Crocodiles & Lizards • Birds & Lizards • Lizards & Snakes

  24. #23. Like the camel, many animals that live in soft sandy areas have large wide feet compared to their body size. The large feet are an advantage in these environments because they — • are rapidly toughened by sharp sand grains • reduce the vibrations caused by walking • distribute body weight over a large area so they don’t sink into the sand • allow rapid digging in the sand

  25. #24. An enzyme known as amylase is found in the saliva of humans. This enzyme helps to begin the process of digesting starch molecules in the foods we eat. Which of these BEST describes how enzymes like amylase help in the process of digestion? • Amylase acts as a buffer to keep the pH of foods at a consistent level. • Amylase breaks down the food molecules directly by forming powerful acids. • Amylase is a catalyst that speeds up the chemical process of breaking down food molecules. d. Amylase contains the DNA molecules necessary to assemble the proteins needed for digestion.

  26. #25. Most organisms break down sugar to produce usable energy through the process of a. Cellular respiration b. Photosynthesis • Transpiration • Diffusion

  27. #26. The nonpoisonous eastern scarlet snake has colored bands that closely resemble the very venomous coral snake. This selective adaptation provides the eastern scarlet snake with — • increased feeding opportunities • increased breeding opportunities • a method of avoiding predation • the ability to attract prey

  28. #27. Cactus have thorns and small hairs on plant stems and leaves help to protect it from animals eating them. These thorns & hairs are an example of a(n): • Vestigial structure b. Homologous structure • Pioneer species • Adaptation

  29. #28. These organisms live in extreme environments like in volcanoes and hydrothermal vents: • Fungi • Eubacteria • Archabacteria • Protozoans

  30. #29. Very large ears on animals that live in hot climates are an adaptation for: • Preventing dirt from getting into their eyes b. Fanning themselves • Hearing prey • Releasing heat and cooling the body

  31. #30. Which of the following statements describes the process of natural selection? • Populations sharing the same gene pool interbreed and create new species. • New species are formed via genetic engineering. • Individuals survive that have inherited traits adapted to their environment. • Farmers select animals with desirable variations for breeding.
