    1. nervous tissue
    2. adipose tissue
    3. connective tissue
    4. smooth muscle
    5. epithelial tissue

  2. The organ system that functions in exchanging gases with the environment is known as the
    1. digestive system
    2. respiratory system
    3. circulatory system
    4. endocrine system
    5. integumentary system

  3. Which of the following statements is NOT part of Darwin’s theory of natural selection
    1. Individuals that are best adapted to their environment tend to pass on heritable advantageous characteristics to their offspring
    2. Genetic variation exists among individuals in a population
    3. The size of most populations remains relatively constant, despite the fact that more offspring are produced than are needed to maintain it
    4. Early settlers saved seed only from the most productive crop plants to plant the following year
    5. both a and d

  4. A tetraploid individual would have
    1. four copies of each chromosome
    2. two copies of each chromosome
    3. one copy of each chromosome
    4. four copies of a single chromosome
    5. six copies of each chromosome

  5. Which of the following best describes the relationship between a population and a species
    1. A species is one type of population
    2. A species is a local subset of a population
    3. A population is a group of organisms occupying a specific area
    4. The terms population and species are interchangeable
    5. none of these

  6. The number of individuals in a population that the environment can just maintain with no net increase or decrease from generation to generation is known as
    1. the dispersion pattern
    2. the habitat cap
    3. the exponential growth curve
    4. the carrying capacity
    5. both a and b

  7. Which of the following pairs of figures would you need to know to determine the population density of elk living in Rocky Mountain National Park
    1. the number of elk living in the park and the area of land encompassed by the park
    2. the birth rate of the elk population and whether population growth is logistic or exponential
    3. the birth rate of the elk population and the area of land encompassed by the park
    4. the number of elk living in the park and the dispersion pattern of the elk population
    5. both b and d

  8. A small isolated population found on a remote island is more likely to undergo speciation than a large widespread population because a small isolated population
    1. inherently contains much greater genetic diversity
    2. is more susceptible to genetic drift
    3. is more readily adaptable to extreme environmental changes
    4. is more likely to migrate to other islands or the nearest mainland
    5. none of these

    1. genus
    2. order
    3. area
    4. species
    5. phylum
