ASU Bio 182 Exam 3 Questions with Approved Answers |Latest 2024/2025

ASU Bio 182 Exam 3 Questions with App roved Answers. 1. Which group is not a population? all four groups are populations 2. How would you estimate the num - ber of whales in a population? mark and recapture 3. What is a population? a group of individuals of the same species living in the same area at the same time 4. True or False? Sampling quadrats would be the better method for es - timating the number of whales in a population. 5. True or False? Mark and recapture would be the better method for es - timating the number of saguaros in a population. 6. True or False? The shrinking popu - lation between 1965 and 1970 could have resulted from a decrease in the birth rate or an increase in the death rate. 7. True or False? The growing popula - tion between 1985 and 1995 could have resulted from a decrease in emigration or an increase in immi - gration. 8. The human population has grown false true true true exponentially 9. The growth of a population de - pends on 10. A population stops growing when it the birth rate minus the death rate. reaches its carrying capacity. ASU Bio 182 Exam 3 Questions with App roved Answers. 11. True or False? The carrying capac - ity of a population depends on the resources available in the environ - ment. 12. Why do bluegills nest on the edge of the lake? true The habitat in the shallow water might receive more solar radiation, holds more zooplankton (which is what they eat), more protective over young than it in deeper water where larger fish re- side, more algae for the fish to hide in, warmer water for embryos to develop quickly and enhance survival/fitness. 13. Activity: Write a Figure Legend Bluegills prefer certain water temp; when given a choice between 27 de - grees celsius and 31 degrees celsius, bluegills spent a majority of their time at 31 degrees celsius. 14. True or False? If males compete for space, a large male will likely force a small male to spend less time on the side of the tank with the optimal temperature. 15. True or False? Both models as - sume that no individuals immigrate into the population. 16. t/f: When possible, a bluegill prefers to have a body temperature around 31°C. true false true 17. T/F: When competing with an adult, False (If the environment hotter than a juvenile bluegill will always have a lower body temperature than its preferred temperature. preferred, on average, large bluegill will force small bluegills to remain in parts of water that are hotter than pre- ferred) ASU Bio 182 Exam 3 Questions with App roved Answers. 18. T/F: All else being equal, the carry - ing capacity of a lake would likely increase as more parts of the lake warm to 31°C. 19. T/F: All else being equal, a juvenile bluegill will likely grow slower in a lake with many adult bluegills than in a lake with few adults 20. T/F: The growth of a bluegill pop- ulation would be better described by a model without density depen - dence than by a model with density dependence. 21. T/F: The number of whales was more likely estimated by sampling than by mark -recapture. 22. T/F: The shrinking population be - tween 1965 and 1970 could have re- sulted from a decrease in the birth rate or an increase in the death rate. 23. T/F: The growing population be - tween 1985 and 1995 could have resulted from a decrease in emigra - tion or an increase in immigration. 24. T/F: Between 2005 and 2008, the sum of the birth and immigration rates roughly equaled the sum of the death and emigration rates. 25. T/F: The growth of this population would be described well by an ex- ponential model. true true false, Because access to suitable tem- peratures is limited, the growth of the population will have a carrying ca - pacity, which requires density depen - dence false true true true false
