Which of the following describes a condition in which logistic growth

would occur

1 2

25% 25%25%25%1. Bacteria grows at a constant rate

2. New Immigration laws in the 1920s slowed immigration in the U.S.A

Which of the following is a long term effect of competition of two species competing for the same resources?

1 2

25% 25%25%25%

1. Rise of prey would be followed by rise in predators. As predators rise, prey declines. Since there are less prey, predators will decline

2. Rise of prey would be followed by rise in predators. Prey will reproduce more rapidly to balance out the reduction of organisms eaten by the predators. The prey will eventually overpower the predators, resulting in more prey

How can you account for the fact that human population has grown more

rapidly the last 500 years?1. The development of agriculture

and industry made life easier thus making food supply more reliable

2. Improved sanitation, medicine and healthcare

3. Improved living conditions increased life expectancy

4. Birth control is not used enough

2. Populations with many more young children and many more teenagers than adults will grow at a faster rate

3. Populations with many young children and less older, will grow very slow

Which of the following is true about the population of the U.S. in 2000?

1. There are more older males than females

2. There is a larger middle age group than any other

age group3. There are more females that are

teenagers
