| Question | Answer |
|---|---|
| On the Galapagos Islands, Charles Darwin observed | somewhat similar species, with traits that were suited to their particular environment |
| In the scientific version of a species name, which of the terms is lowercase? | the second term only |
| The most general and largest category in the classification of organisms is | the domain |
| The domain that corresponds to the kingdom Eubacteria is | Bacteria |
| Organisms that contain membrane-bound nuclei, do not have a cell wall, and must consume organisms to gain the nutrients needed for survival are classified into which kingdom? | Animalia |
| Organisms that contain membrane-bound nuclei, contain a cell wall composed of chitin, and must consume the nutrients needed for survival are classified into which kingdom? | Fungi |
| Unicellular organisms that do not contain membrane-bound nuclei, contain a cell wall without peptidoglycan, and depending upon the species, can be considered either autotrophs or heterotrophs are classified into which kingdom? | Archaea |
| Unicellular organisms that do not contain membrane-bound nuclei, contain a cell wall composed of peptidoglycan, and depending upon the species, can be considered either autotrophs or heterotrophs are classified into which kingdom? | Eubacteria |
| All organisms in the kingdoms Protista, Plantae, Fungi, and Animalia are | eukaryotes |
| Which kingdom contains heterotrophs with cell walls of chitin? | fungi |
| An understanding of which of these best enables scientists to determine the approximate age of fossils? | radioactivity |
| Fossils help scientists classify extinct species and determine their relationships to current species. Fossils provide the most information about extinct species' | structures |
| Over many generations, unrelated or distantly related species may come to resemble each other due to-- | similar environmental factors |
| One necessary condition for the evolution of the first life on Earth was | the presence of liquid water |
| Fossilized evidence of Earth's first forms of life would consist of | prokaryotes from the Precambrian |
| A pattern in which species experience long, stable periods interrupted by brief periods of rapid evolutionary change is called | punctuated equilibrium |
| ______ is a method of determining the age of a fossil by comparing its placement with that of fossils in other layers of rock. | relative dating |
| ______ is a method of determining the approximate age of a fossil in number format by using radioactive minerals in rocks or other organic minerals as geological clocks | absolute dating |
| The number and location of bones of many fossil vertebrates are similar to those in living vertebrates. Most biologists would probably explain this fact on the basis of | A common ancestor |
| An adaptation is an inherited characteristic that can be | passed down to future generations |
| According to Darwin's theory of natural selection, individuals who survive are the ones best adapted for their environment. Their survival is due to the | possession of inherited adaptations that maximize fitness |
| When a farmer breeds only his or her best livestock, the process involved is | artificial selection |
| The same kinds of cells that grow in similar patterns in different but related organisms produce | homologous structures such as wings and arms |
