HiSet Science Practice Test #1

What is the main difference between the normal strain and the mutant strain of Bacteria X according to the information provided?

• The normal strain requires methionine to reproduce, while the mutant strain does not.

• The mutant strain has a different shape and size than the normal strain.

• The normal strain can survive without glucose, while the mutant strain cannot.

• The mutant strain can reproduce in a medium with methionine, while the normal strain cannot.

Based on the experiment, what can be inferred about the role of methionine in the survival of normal Bacteria X?

• Methionine is not necessary for the survival of normal Bacteria X.

• Methionine is harmful to the survival of normal Bacteria X.

• Methionine is necessary for the survival of normal Bacteria X.

• The presence of methionine has no impact on the survival of Bacteria X.

On the basis of these results, what can be concluded about Bacteria X’s need for methionine?

• It is essential for both types of Bacteria X.

• It is not essential for either type of Bacteria X.

• It is essential only for normal Bacteria X.

• It is essential only for mutant Bacteria X.

The experiment was devised to test the necessity of methionine for the survival of normal Bacteria X. Why were mutant Bacteria X also used in the experiment?

• As a second dependent variable, to give the researcher data on two strains of bacteria

• As a second experimental variable, to give the researcher another factor to manipulate

• As a control, to show that not all organisms are dependent on methionine

• As a control, to show that normal Bacteria X died from lack of methionine and not from some other factor

At the beginning of this experiment, what assumption did the biology class make about the bacteria’s food requirements?

• The amounts of glucose and inorganic foods in both dishes are sufficient to allow both bacteria to survive and reproduce.

• Both bacterial strains require amino acids other than methionine in their food or environment.

• Mutant Bacteria X require methionine in their food or environment, but normal Bacteria X do not.

• Normal Bacteria X reproduce at a faster rate than do mutant Bacteria X.

To determine how the amount of methionine in the medium affects the survival of normal Bacteria X, which of the following changes in the experimental design would be most appropriate?

• Add a series of dishes similar to Dish #2, with different concentrations of methionine in each

• Add a series of dishes similar to Dish #2, with different concentrations of glucose, organic foods, and methionine in each

• Prepare Dishes #1 and #2, except add only 100 normal Bacteria X to each dish

• Prepare Dishes #1 and #2, except add different amounts of methionine to each dish

What is a lunar eclipse?

• The event when the Earth passes through some portion of the Moon's shadow.

• The event when the Moon passes through some portion of Earth's shadow.

• The event when the Sun passes through some portion of Earth's shadow.
