Which of the following represents a biome?
A. An extended family of chimpanzees
B. A stand of bamboo
C. An orchid and the insects that feed on it
D. A tropical rain forest correct answers Option (D) is correct. A biome is a large geographic
area with a climate that supports distinctive plant and animal groups. A tropical rain forest is
an example of a biome.
Which of the following planets is closest to the Sun?
A. Mars
B. Mercury
C. Saturn
D. Venus correct answers Option (B) is correct. Mercury is the planet closest to the Sun.
Which of the following substances is readily attracted to a magnet?
A. Gold
B. Nickel
C. Carbon
D. Nitrogen correct answers Option (B) is correct. Nickel, like iron and cobalt, is a metal that
is attracted to a magnet.
A graduated cylinder is typically used to measure which of the following?
A. Temperature
B. Composition
C. Volume
D. Mass correct answers Option (C) is correct. A graduated cylinder is typically used to
measure volume. Common graduated cylinders range in size from 10 mL to 1 L.
Which THREE of the following statements about stars are true?
A. The Sun is a star.
B. Most stars orbit planets.
C. Various stars have different surface temperatures.
D. Some stars exist for longer periods than other stars. correct answers The correct answers
are (A), (C), and (D). The surface temperatures of main-sequence stars largely depend on
their mass, which varies from star to star. The Sun is a main-sequence star that generates
energy by nuclear fusion of hydrogen. How long stars exist largely depends on their mass.
Chloroplasts are found in the cells of which of the following organisms?
A. Clams
B. Tulips
, C. Parrots
D. Starfish correct answers Option (B) is correct. All plant and algal cells contain
chloroplasts. Tulips are plants and therefore contain plant cells and chloroplasts.
The tendency of an object to resist change in motion is called
A. mass
B. inertia
C. friction
D. velocity correct answers Option (B) is correct. Inertia is the tendency of a physical object
to resist change in motion unless acted on by an outside force.
Which of the following best describes how a small saltwater spill should be cleaned up in the
elementary classroom?
A. Allow the spill to spread so that the water can quickly evaporate, then sweep up the salt.
B. Wipe up the spill with paper towels from the outer edge toward the center to minimize the
spread of the spill.
C. Add water to dilute the salt water and increase the volume of the spill to ensure that all the
students can help wipe up the spill.
D. Use the classroom sponge to absorb the spill, then squeeze out the salt water into its
original container so that it can be reused. correct answers Option (B) is correct. Minimizing
the area of the saltwater spill while effectively cleaning up the liquid reduces any potential
safety hazards that the spill may create.
The force of electrostatic attraction increases when which of the following are brought closer
together?
A. Two negatively charged objects
B. Two positively charged objects
C. Two neutral objects
D. One positively charged object and one negatively charged object correct answers Option
(D) is correct. The force of electrostatic attraction increases when oppositely charged objects
are brought closer together. Objects with the same charge have electrostatic repulsion when
brought closer together. Neutral (uncharged) objects have neither attraction nor repulsion.
An x-ray image is typically used to diagnose which of the following?
A. A muscle tear
B. A broken bone
C. Cardiac arrhythmia
D. Low blood-oxygen levels correct answers Option (B) is correct. An x-ray image can
reveal broken bones through layers of skin, muscle, and other tissue.
Which of the following is an example of chemical weathering?
A. The removal of soil along the banks of a river by the flowing water
B. The sculpting of rocks by sand carried by the wind
C. A sidewalk crack getting larger when water in the crack freezes
