6
The world's annual growth rate in 2000 will be _______ percent.
1.4
A rate of 4.0% annual increase will double the population for a country in ____ years.

Which area of world today is experiencing the shortest doubling time?
Africa
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
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
T/F: The unrestricted growth of a population is sometimes referred to as its biotic potential.
False
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
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
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
T/F: The k-strategy populations are limited by density-independent factors.
False
T/F: The unrestricted growth of populations resulting in the maximum number of organism for a particular population is called its biotic potential.
False
T/F: Humans have the k-strategy as reproductive strategy.
True
T/F: A megacity is defined as having a population of more than 1 million.
False
T/F: China was the first country to introduce family planning.
False
T/F: The one child policy is enforced in China.
True
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.
