PIB Biology Semester I Final Exam Study Guide 1. A pH of 4 is how many times more acidic than a pH of 7? 2. A relationship in which two species are dependent on each other for survival is 3. A solution has a hydrogen ion concentration [H+] of 10-10 at 25 degrees Celsius. What is the pH of the solution? 4. Adaptations of the kangaroo rat to living in the dry, hot environment of the southwestern United States include 5. Algal blooms eventually deplete freshwater habitats of 6. As population density increases, the chance of ____ also increases. 7. Coevolution is 8. Evapotranspiration allows water to travel against gravity from the soil, to a plant’s roots, to its leaves, and then to the atmosphere. This process is maintained by 9. Figure 2 shows root systems of three annual plant species that live together. The fact that all three species survive in the same habitat is due to 10. Habitat fragmentation can reduce biodiversity by 11. Hydrophobic molecules are ____ water 12. If a kangaroo rat does not ingest any liquids, how does it gain most of its water? 13. In Figure 1, the effect of population growth limiting factors begin to become evident at about 14. In Figure 1, the population is in exponential growth at 15. In pure, liquid water, other than water molecules, what two ions can be found? 16. Liquid water is a universal solvent, exhibits the property of cohesion, and resists changes in temperature. These properties of water are due to 17. Many species of animal have evolved structures, functions, and behaviors that employ the evaporative cooling ability of water. Which emergent property of water gives it the ability to cool an animal’s skin upon evaporation? 18. Most amphibians lose a lot of water through their skin, so they spend most of their time in moist habitats and excrete ammonia or urea in their urine. Some amphibians spend 1

Suppose 200 goldfish (Carassius auratus) are marked and released in a pond. The following week, 200 fish are caught and 50 of them are marked. Approximately how many goldfish might there be in the population? 20. The animal in Figure 3 is using ____ for protection. 21. The antidiuretic hormone (ADH)
