  • Question 5
    30 seconds
    Q. The snowshoe rabbit has white fur in winter and dark fur in summer. What is the main survival advantage of this fur color change to the rabbit?
    answer choices
    The light fur keeps the rabbit from getting sunburned in summer.
    The fur color is an adaptive form of camouflage to avoid predators.
    The dark fur absorbs more sunlight so the rabbit is warmer in winter.
    The white fur is more valuable to fur trappers, so the animal will be trapped and better fed in winter.
  • Question 6

    answer choices
    That they shared a common ancestor.
    That mammals are evolving to become more and more like one another.
    That they developed their bone structure independently of one another.
    That the shape of the bones has less to do with the environment pressures on the animal, and more to do with what their relatives are.

  • Question 21
    60 seconds
    Q. In 1967 a penicillin-resistant pneumonia, caused by Streptococcus pneumoniae and called pneumococcus, surfaced in a remote village in Papua, New Guinea. 
    At about the same time American military personnel in southeast Asia were acquiring penicillin-resistant gonorrhea from prostitutes. By 1976, when the soldiers had come home, they brought the new strain of gonorrhea with them and physicians had to find new drugs to treat it. 
    In 1983 a hospital-acquired intestinal infection caused by the bacterium Enterococcus faecium joined the list of bacteria that could not be killed by penicillin.
    Which of these BEST describes why certain bacteria have become resistant to penicillin?
    answer choices
    The penicillin in the 1970's was much weaker that the penicillin used today, thus it was not as effective.
    Penicillin was not effective in treating any bacterial diseases, so the doctors had to find new treatments.
    These new bacterial strains came out of the jungles and forests already equipped to be penicillin-resistant.
    Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive.
  • Question 22
    30 seconds
    Q. Apple farmers are currently having a very difficult time with pesticide-resistant insects. These insects are no longer being killed by the current chemical treatments, thus causing a lot of damage to the apple crops. In reaction to this, researchers are developing newer and stronger chemicals to help control the bugs.
    Why are the apple farmers seeing these new, stronger bugs?
    answer choices
    The bugs were not native to the area and thus cannot be killed by normal chemicals.
    Changes in the weather have led to stronger insects that can survive these harsh changes.
    The strongest bugs were able to survive pesticides, reproduce and create more resistant pests.
    The apple trees are producing too many apples, which is allowing the insects to reproduce rapidly.

  • Question 27
    30 seconds
    Q. If stranded on a deserted island with no freshwater, it is not advisable to drink sea water. Why not?
    answer choices
    The salty snacks cause an ionic imbalance that triggers a nervous response.
    The salt in the body creates a hypertonic solution around cells, which causes water to diffuse out of cells and make them crenate.
    The salt in the body creates a hypotonic solution around cells, which causes water to diffuse into cells and make them cytolyse.
    The salt in the body creates an isotonic solution around cells, which causes water to diffuse into and out of cells which makes them unstable.
  • Question 28
    30 seconds
    Q. If one defines life as the simplest form capable of displaying the most essential attributes of a living thing, one very quickly realizes that the only real criterion for life is the ability to replicate. Only systems that contain nucleic acids are capable of this phenomenon. This sort of reasoning has led to a new definition of organism:
    An organism is the unit element of a continuous lineage with an individual evolutionary history.
    Considering the new definition of life, all but one piece evidence supports the fact that a virus must be referred to as an organism. That is:
    answer choices
    Viruses contain nucleic acids.
    Viruses are capable of replication.
    Viruses have a simple cellular structure.
    Viruses have an evolutionary history and that implies lineage.
  • Question 29
    30 seconds
    Q. Compare primary and secondary succession of an ecosystem. What is the distinction between them?
    answer choices
    Primary succession is the sequence of plants that colonize a new area, while secondary succession is the sequence of animals that move once plant life is established.
    Primary succession is the sequence of species that become established early in a newly colonized area, while secondary succession is the sequence of species that move in much later.
    Primary succession is the establishment of a new community in an existing ecosystem that was disturbed, while secondary succession is the establishment of a community in an area that was altered due to fire.
    Primary succession is the establishment of a community in an area with no soil, while secondary succession is the establishment of a new community in an existing ecosystem that was disturbed by some catastrophic event.
