  3. white speck tunicate
  4. starry skate
Two groups of organisms are found living on opposite sides of an island. An active volcano prevents each group from traveling to the opposite side of the island. Scientists want to know if these two groups of organisms belong to the same species. Which question should scientists try to answer?
  1. Do the two groups eat the same kinds of food?
  2. Are the two groups active at the same times each day?
  3. Can the two groups interbreed to produce fertile offspring?
  4. Do the two groups use similar anatomical structures for the same purpose?
Which pair of organisms are most closely related?
  1. Asterias rubens and Asterias forbesi
  2. Bubulcus ibis and Xenicibis xympithecus
  3. Ophiderma salamandra and Salamandra algira
  4. Ceanothus americanus and Lethocerus americanus
Which statement is correct about the hierarchy of the taxonomic system currently used to classify organisms?
  1. All organisms of a given order belong to the same species.
  2. Many different classes of organisms belong to the same order.
  3. All organisms of a given phylum belong to the same kingdom.
  4. Many different families of organisms belong to the same genus.
Long-tailed weasels and European otters are both classified into the family Mustelidae. Which type of information was most likely used to classify these animals into the same family?
  1. food source
  2. skeletal structure
  3. method of movement
  4. location of natural habitat
Until recently, the myrtle warbler and the Audubon’s warbler were thought to be separate species of birds because the males have very different appearances. Which observation most likely led to the reclassification of these warblers as one species?
  1. The warblers have the same diet.
  2. The warblers lay the same number of eggs.
  3. The warblers have overlapping geographical ranges.
  4. The warblers interbreed and produce fertile offspring.

  2. B and C
  3. C and D
  4. A and D
  5. They are equally similar.
Which statement best explains why the chestnut-sided warbler, Dendroica pensylvanica, and the cerulean warbler, Dendroica cerulea, are classified as closely related species?
  1. They eat the same types of insects.
  2. They have similar DNA sequences.
  3. They show similarities in their nesting behaviors.
  4. They live in the same types of woodland habitats.
In binomial nomenclature,
  1. the first word identifies the color of the organism, and the second word tells where the organism is usually found.
  2. the first word identifies the organism's genus, and the second word describes a feature of the organism or place where it was found.
  3. the first word tells where the organism lives, and the second word tells who originally found the organism.
  4. the first and second word both identify important characteristics of the organism.
