1. The ability to grow in size is a characteristic of living organisms. Although an icicle may grow in size over
time, it is considered nonliving because there is…
A. an increase in matter, but no increase in the number of icicles.
B. an interaction between the icicle and the environment.
C. no way for the icicle to move away from heat.
D. no metabolic activity present.
2. A company that manufactures a popular multivitamin wanted to determine whether their multivitamin had
any side effects. For its initial study, the company chose 2000 individuals to take one of their multivitamin
tablets per day for one year. Scientists from the company surveyed the participants to determine whether
they had experienced any side effects. The greatest problem with this procedure is that
A. only one brand of vitamin was tested.
B. the study lasted only one year.
C. the sample size was not large enough.
D. no control group was used.
An experiment was designed to test whether students could squeeze a clothespin more times in one minute after
resting or after exercise.
3. The dependent variable for this experiment is the
A. time the student was squeezing the clothespin.
B. number of times the student was able to squeeze the clothespin.
C. strength of the student.
D. length of the clothespin.
4. The experimental result could be made more valid by
A. increasing the time.
B. using a plastic clothespin.
C. using safety precautions.
D. setting a specific type of exercise.
5. The leaves of a plant are dotted with opening known as stomata. When open, stomata allow the plant to
exchange gases and allow moisture to evaporate, helping to draw water from the roots up into the plant.
These activities help the plant to
A. produce light energy.
B. maintain homeostasis.
C. undergo cellular division.
D. synthesize minerals.
6. Why is a mushroom considered a heterotroph?
A. It manufactures its own food.
B. It divides by mitosis.
C. It transforms light energy into chemical energy.
D. It obtains nutrients from its environment.
The data table shows an effect of secondhand smoke on the birth weight of babies born to husbands and wives
living together during pregnancy.
Effect of Secondhand Smoke on Birth Weight
Wife: Nonsmoker
Wife: Nonsmoker
Husband: Nonsmoker
Husband: Smoker
Number of Couples
837
529
Average Weight of Baby at Birth
3.2 kg
2.9 kg
7. Based on these data, a reasonable conclusion that can be drawn about secondhand smoke during pregnancy
is that secondhand smoke
A. is unable to pass from the mother to the fetus.
B. slows the growth of the fetus.
C. causes mutations in cells of the ovaries.
D. blocks the receptors on antibody cells.
8. The ability of the human body to keep blood sugar levels within a fairly narrow range, despite the intake of
meals high in carbohydrates, is an example of
A. metabolism.
B. asexual reproduction.
C. an adaption.
D. homeostasis.
9. Which statement best describes a hypothesis?
A. A hypothesis is the process of making careful observations.
B. The conclusion drawn from the results of an experiment is part of a hypothesis.
C. A hypothesis serves as a basis for determining what data to collect when designing an experiment.
D. The facts collected from an experiment are written in the form of a hypothesis.
A scientist conducted an experiment to test the hypothesis that maple seeds exposed to acid rain will take longer
to germinate than seeds exposed to normal rain, which has a pH of 5.6. The scientist set up four groups, each
containing 200 maple seeds. The water used for each group had a different pH value: 5.6, 4.0, 3.0, and 2.0. All
other conditions were kept the same. After ten days, the number of seeds that had germinated in each group
was counted.
10. Identify the control group: _______________________________________________________________
11. Identify the independent variable: _________________________________________________________
12. Identify the dependent variable: __________________________________________________________
13. In an experiment, the variable that is deliberately changed is the
a. inferred
c. dependent
b. independent
d. controlled
variable.

15. The information gathered during an experiment is called __________________________.
16. A(n) ___________________________ is a logical interpretation based on what scientists already know.
17. A(n) ___________________________ is a scientific explanation for a set of observations that can be tested
in ways that support or reject it.
18. A(n) ___________________________ is a well-tested explanation that unifies a broad range of
observations and hypotheses.
19. In ___________________________ reproduction, the new organism has a single parent.
