information. B. Living things have the ability to create energy.
C. Living things are composed of cells.
D. Living things undergo evolutionary adaptation.
E. Living things have the ability to replicate.
2. Which statement is not a component of the cell theory?
A. All organisms are made of cells.
B. All cells arose from RNA-based systems.
C. All cells come from pre-existing cells.
D. All of the above are components of the cell theory.
3. Which choice is an example of artificial selection?
A. The long neck of a giraffe.
B. Dog breeds with short legs.
C. Ants trying to find their nest while walking on stilts.
D. All of the above result from artificial selection.
4. Which choice best describes evolution?
A. The characteristics of a species become more complex over time.
B. The strongest individuals produce the most offspring.
C. The characteristics of an individual change over the course of its
life. D. The characteristics of a population change over time.
5. In an experiment, investigators try to control all of the variables except one—the one that tests
the hypothesis. Which of the following reasons is the primary rationale for controlling variables in an
experiment?
A. To enable investigators to repeat the test.
B. To create a control group.
C. To eliminate alternative explanations for the results of an experiment.
6. Louis Pasteur’s experiments with different flasks disproved which hypothesis?
A. All organisms are made of cells.
B. Spontaneous generation.
C. Evolution.
D. All cells come from pre-existing cells.
, 7. You have isolated and purified a new species of single-celled organism from the arctic ocean and you
want to place this new species in the appropriate branch of the tree of life. You sequence the
ribosomal RNA genes from these cells and discover that for one particular region of the ribosomal gene
the RNA sequence is AAUGAAGG.
You have sequences from the same region of the ribosomal genes from each of these organisms:
bacteria, eukaryote and archaea, which are listed below.
bacteria AUAGAUGG
eukaryote AAAGAAGG
archaea AAUGGAGU
Based on these sequence results, to which branch of the tree of life should you assign this new species?
A. Archaea
B. Bacteria
C. Bacteria and archaea
D. Eukaryote
E. There is not enough information
8. Humans are eukaryotes.
A. True
B. False
9. Which of the following best describes a hypothesis?
A. A hypothesis is like a blind guess.
B. A hypothesis is a testable explanation for an observation.
C. A hypothesis is proof of an idea.
D. A hypothesis is a conclusion drawn from experiments.
10. One ml (milliliter) of an experimental drug diluted in a saline (salt) solution is injected into 20
pregnant mice to determine possible side effects. Which of the following is a suitable "control" for
this experiment?
A. 20 male mice injected with 1 ml of saline.
B. 20 male mice injected with 1 ml of the drug.
C. 20 pregnant mice injected with 1 ml of saline.
D. 20 non-pregnant mice injected with 1 ml of the drug.
11. Sarah and Todd go to a new restaurant and do not like the food they are served. Their hypothesis is
that if they go to the restaurant again, they will not like the food. If they continue to follow the scientific
method, what should they do next?
A. Never go near the restaurant again and tell all their friends to avoid
it. B. Go back to the restaurant several times and order different items.
C. Survey other customers to see if they like the food.
D. Call the city health inspectors and suggest they inspect the restaurant.
E. Get some friends to go to the restaurant and order what Sarah and Todd didn’t like.
