  1. 1There are two different types of exotic cats living in Africa. One of them has spots all over making it easy to camouflage with its surroundings, which allows them to hide from their predators. The other is plain white, which in other words is more susceptible to harm as opposed to others. Although one is more favorable than the other, both of the animals have been thriving at the same rate for 5 years now. Is this particular situation a form of natural selection? Why or why not?
    1. AYes, because one of the exotic cats are more favorable than the other. One is going to survive and the other will cease to exist.
    2. BNo, because both exotic cats remain stable in the population although they have different traits in fur color.
    3. CYes, because one particular trait is providing an advantage to an organism in a certain environment.
    4. DNo, because natural selection only occurs with different species of animals; it's never for just one type of animal.
  2. 2Evolution is change over time. The leaves of trees changing color in the fall is an example of evolution.
    1. ATrue
    2. BFalse
  3. 3There are two islands separated from one another by a body of water. Elephants that once lived on the same land now differ in traits they have because of the barrier that came before them. They are no longer able to mate with each other due to their proximity. What kind of barrier does this situation represent exactly?
    1. AReproductive Isolation
    2. BGeographic Isolation
    3. CSpeciation
    4. DLand Isolation
  4. 4Rabbit's ears can be either short or floppy, where short ears are dominant over floppy ears. There are 653 individuals in a population. 104 rabbits have floppy ears and 549 have short ears.
    Find: the frequency of the dominant and recessive alleles and the frequency of individuals with dominant, heterozygous, and recessive genotypes.
    1. Ap = 0.6
      q = 0.4
      p^2 = 0.36
      2pq = 0.48
      q^2 = 0.16
    2. Bp = 0.4
      q = 0.6
      p^2 = 0.16
      2pq = 0.48
      q^2 = 0.36
    3. Cp = 104
      q = 549
      p^2 = 200
      2pq = 549
      q^2 = 1000
    4. Dp =0.6
      q = 0.4
      No, the population is not in a state of Hardy-Weinberg equilibrium because the allele frequencies are not the same as the preceding generation.
  5. 5Which of the following statements is TRUE?
    1. ALess than 60% of all natural populations of plants and animals have diversity--that is, they are not clones.
    2. BThe earth's environments have remained unchanged since the end of the last ice age.
    3. CHumans have altered the environments of some species in order to control the direction of their evolution.
    4. DNone of the above
  6. 6Check all the boxes that apply to this figure.Image for question 6
    1. AThe sister group to taxon B is taxon C.
    2. BThe trait of feathers applies to both the birds and crocodiles.
    3. CA represents the common ancestor for birds.
    4. DIn this tree, taxon A is the outgroup.
  7. 7According to the phylogenetic tree, which organisms are the least related to each other evolutionarily?Image for question 7
    1. ATrilobita and Insecta
    2. BInsecta and Myriapoda
    3. CInsecta and Crustacea
    4. DTrilobita and Chelicerata
  8. 8A plague that sweeps through a population and kills individuals who have a certain genetic makeup more than others is considered a bottleneck situation.
    1. ATrue
    2. BFalse
  9. 9In which population would you expect the most rapid evolutionary change?
    1. AA small population with a high mutation rate in a changing environment.
    2. BA small population with a low mutation rate in a stable environment.
    3. CA large population with a high mutation rate in a changing environment.
    4. DA large population with a low mutation rate in a stable environment.
  10. 10What is a major cause of variation within a species?
    1. ASexual reproduction
    2. BAsexual reproduction
    3. CExtinction
    4. DPhotosynthesis
