  21. T/F: Those countries with more stable populations such as the United States have an age distribution where there are fewer infants and children than young adults.
    False
  22. T/F: Birth rate is normally expressed as the number of live births per 1,000 population (counting the population at the endpoint of the year).
    False
  23. T/F: The unrestricted growth of a population is sometimes referred to as its biotic potential.
    False
  24. T/F: The sum of the limiting factors serve to control the numbers of a species that can survive in defined area over time and this represents the carrying capacity of that area for a particular species.
    True
  25. T/F:The r-strategy populations are typically small, short-lived organisms, which produce large numbers of offspring and receive little or no parental care.
    True
  26. T/F: If an organism grows too rapidly and the population escalates beyond the carrying capacity of the environment in which it is located, a "S" type growth curve may develop.
    False
  27. T/F: The k-strategy populations are limited by density-independent factors.
    False
  28. T/F: The unrestricted growth of populations resulting in the maximum number of organism for a particular population is called its biotic potential.
    False

    False
  32. T/F: The one child policy is enforced in China.
    True
  33. T/F: The population has grown so much that even the smaller growth rates lead to additions of larger numbers of people to the global population. This is referred to the momentum.
    True
