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 - answer 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 - answerOption (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 - answerOption (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 - answerOption (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. - answerThe 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 - answerOption (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 - answerOption (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. - answerOption (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 - answerOption (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.
