Explanation:

• Question 6: A negative growth rate implies a decrease in population size over time.
• Question 7: When resources are limited, populations follow a logistic - growth pattern, which levels off as it approaches the carrying capacity.
• Question 8: Most real - world populations exhibit logistic growth due to limited resources.
• Question 9: The score on the final test depends on the number of hours studying, making it the dependent variable.
• Question 10: The independent variable is the factor that is manipulated or changed. Here, drinking milk is what Jose is changing to observe its effect on his son's growth.
• Question 11: Birth and death rates are fundamental factors that directly affect population growth.

Answer:

• 6. C. The population is declining
• 7. B. Logistical growth
• 8. A. Logistical
• 9. D. The score on the final test
