    Coastal snakes can detect odor molecules produced by banana slugs.
    Coastal snakes have a genetically acquired taste for banana slugs.
    Coastal snakes that readily eat banana slugs gain most of their calories from this prey species.
    Coastal snakes can detect odor molecules produced by banana slugs.
    Coastal snakes have a genetically acquired taste for banana slugs.

          

  2. Although many chimpanzees live in environments containing oil palm nuts, members of only a few populations use stones to crack open the nuts. The likely explanation is that

    members of different populations have different nutritional requirements.
    the cultural tradition of using stones to crack nuts has arisen in only some populations.
    members of different populations differ in manual dexterity.
    the behavioral difference is caused by genetic differences between populations.
    members of different populations differ in learning ability.

    The presence of broadleaf and presence of coniferous forest
    The growth rate of the Paramecium population will increase.

          

  4. Which statement accurately describes the potential effects of disturbance on species diversity?

    Moderate levels of disturbance generally act to reduce species diversity within a community.
    In many biomes, periodic disturbances may eliminate the dominant plants.
    Many species are well adapted to survive periodic disturbances.
    Many species are well adapted to survive periodic disturbances.
