QUESTIONS
Which-of-the-following-geological-processes-adds-new-rock-to-the-surface-of-the-Earth?
(A)-Volcanic-Activity-
(B)-Glacial-Activity-
(C)-Soil-Erosion
(D)-Weathering---ans-✔✔(A)-Volcanic-Activity-
Volcanic-activity-is-the-only-process-by-which-material-from-inside-Earth-is-brought-to-the-
surface.-The-other-processes-are-means-of-wearing-down-Earth's-surface.
Which-THREE-of-the-following-are-ways-in-which-mammals-keep-themselves-warm-in-
cold-weather?
(A)-Shivering
(B)-Perspiring
(C)-Fluffing-out-coat-hair
(D)-Contracting-certain-blood-vessels---ans-✔✔(A),-(C),-and-(D)
Shivering-produces-heat.-Fluffing-out-coat-hair-provides-insulation-and-helps-to-retain-
body-heat.-Contracting-certain-blood-vessels-reduces-blood-flow-to-extremities-and-thus-
reduces-heat-loss.-However,-perspiring-does-not-help-because-the-skin-is-cooled-as-
energy-is-absorbed-by-the-sweat-as-it-evaporates.
If-a-feather-and-two-rocks-of-different-weights-were-dropped-simultaneously-from-a-height-
of-5-meters-in-a-vacuum,-which-of-the-following-would-be-true?
(A)-Both-rocks-would-hit-the-ground-at-the-same-time,-but-before-the-feather.
(B)-The-heavier-rock-would-hit-the-ground-first.
(C)-The-lighter-rock-would-hit-the-ground-first.
(D)-The-feather-and-the-two-rocks-would-all-hit-the-ground-at-the-same-time.---ans-✔✔(D)-
The-feather-and-the-two-rocks-would-all-hit-the-ground-at-the-same-time.-
In-a-vacuum,-all-objects-fall-freely-with-the-same-constant-acceleration-regardless-of-their-
mass.
Which-of-the-following-lab-instruments-would-be-most-appropriate-to-use-in-determining-
the-volume-of-a-large-block-of-wood-of-unknown-density?
(A)-A-metric-ruler
(B)-A-triple-beam-balance
(C)-A-200-mL-volumetric-flask
(D)-A-micrometer---ans-✔✔(A)-A-metric-ruler
,To-find-the-volume-of-a-large-rectangular-block-of-wood,-first-use-the-metric-ruler-to-find-
the-length,-width,-and-height-of-the-block.-Then-use-the-formula-for-the-volume-of-a-
rectangular-solid—-length ́-width ́-height-—to-determine-the-volume.
A-scientific-hypothesis-is-a-statement-that:-
(A)-Ensures-an-experiment-will-produce-positive-results
(B)-Is-accepted-by-most-of-the-scientific-community
(C)-Is-a-proposal-that-may-lead-to-experimental-testing
(D)-Is-formulated-by-a-renowned-scientist---ans-✔✔(C)-A-proposal-that-may-lead-to-
experimental-testing.-
A-hypothesis-is-a-proposed-explanation-of-a-scientific-problem.-After-the-hypothesis-is-
proposed,-scientific-experimentation-may-be-conducted-that-produces-data-that-can-
either-support-or-fail-to-support-the-hypothesis.
Which-of-the-following-is-the-broadest-category-in-the-biological-taxonomy?
(A)-Kingdom
(B)-Order
(C)-Genus-
(D)-Species---ans-✔✔(A)-Kingdom
When-putting-living-things-into-a-biological-classification-scheme,-the-broadest-category-
is-kingdom,-followed-by-phylum,-class,-order,-family,-genus,-and-species.
Some-human-traits-are-carried-by-genes-on-the-Y-chromosome.-A-man-will-transmit-these-
traits-to:
(A)-One-half-of-his-male-offspring-only
(B)-One-half-of-his-female-offspring-only
(C)-All-of-his-male-offspring
(D)-All-of-his-female-offspring---ans-✔✔(C)-All-of-his-male-offspring
Human-males-generally-have-one-X-and-one-Y-chromosome.-Male-offspring-will-only-
receive-a-Y-chromosome-from-their-father,-while-female-offspring-will-only-receive-an-X-
chromosome-from-their-father.-Therefore,-genes-on-the-Y-chromosome-are-passed-only-
to-male-offspring.
A-chlorine-compound-is-added-to-swimming-pools-in-order-to:-
(A)-Monitor-the-pH-of-the-water
(B)-Add-color-to-the-water
(C)-Soften-the-water-by-precipitating-harmful-chemicals
(D)-Destroy-bacteria-through-an-oxidation-reaction---ans-✔✔(D)-Destroy-bacteria-through-
an-oxidation-reaction.-
Chlorine-and-certain-chlorine-containing-compounds-are-highly-reactive-oxidizing-agents-
that-are-used-as-chemical-disinfectants-in-a-variety-of-situations,-including-swimming-
pools.
Two-campers-each-wrap-a-potato-in-aluminum-foil-prior-to-baking-them-in-fire.-However,-
one-camper-inserts-a-large-nail-into-her-potato-after-wrapping-it-in-the-foil.-After-the-
potatoes-are-placed-in-the-fire,-which-of-the-following-is-most-likely-to-happen?
, (A)-Both-potatoes-will-bake-at-the-same-rate
(B)-Neither-potato-will-bake-because-the-foil-will-reflect-most-of-the-heat
(C)-The-potato-with-the-embedded-nail-will-bake-faster-because-heat-will-be-conducted-
through-the-nail-into-the-potato
(D)-The-potato-with-the-embedded-nail-will-bake-more-slowly-because-heat-will-be-
conducted-out-of-the-potato-through-the-nail---ans-✔✔(C)-The-potato-with-the-embedded-
nail-will-bake-faster.-
Although-the-aluminum-foil-will-reflect-some-radiant-energy,-it-will-not-significantly-reduce-
the-flow-of-energy-by-conduction.-Because-a-nail-is-a-good-thermal-conductor,-heat-will-
flow-into-the-potato-through-the-nail-and-bake-the-potato-from-the-inside-as-well-as-from-
the-outside.-Thus,-the-potato-with-the-imbedded-nail-will-bake-faster.

(C)-An-ocean-current-called-the-Gulf-Stream-flows-northward-along-the-east-coast-of-the-
U.S.-and-Newfoundland.-
(D)-The-Himalayas-were-formed-by-plate-tectonics.---ans-✔✔(B)-Earth-once-contained-a-
single-supercontinent.-
In-the-early1900s-,-Alfred-Wegener-proposed-a-theory-that-Earth-once-contained-a-single-
large-landmass-called-Pangaea.
Which-of-the-following-is-a-chemical-element?
(A)-Sodium-Chloride
(B)-Platinum
(C)-Carbon-Dioxide
(D)-Water---ans-✔✔(B)-Platinum
Platinum-is-a-chemical-element-found-on-the-periodic-table-of-elements.-Its-chemical-
symbol-is-Pt.-Sodium-chloride,-carbon-dioxide,-and-water-are-compounds-that-are-each-
composed-of-combinations-of-two-different-elements.
Of-the-following,-which-best-describes-an-example-of-the-Doppler-effect?
(A)-As-light-passes-through-a-prism,-the-light-separates-into-a-rainbow
(B)-As-a-light-beam-passes-from-air-into-water,-the-beam-changes-direction
(C)-As-an-emergency-vehicle-approaches-an-observer-standing-by-the-road,-the-pitch-of-
its-siren-increases.-
(D)-As-a-sound-wave-hits-a-wall,-it-is-reflected-and-creates-an-echo.---ans-✔✔(C)-As-an-
emergency-vehicle-approaches-an-observer-standing-by-the-road,-the-pitch-of-its-sirens-
increases.-
According-to-the-Doppler-effect,-as-the-source-of-a-sound-moves-toward-an-observer-at-a-
fixed-position,-the-successive-sound-waves-arrive-faster-and-faster-at-the-observer's-
position,-resulting-in-an-increase-in-the-frequency-of-the-sound-waves-arriving-at-the-
observer's-position.-Since-the-pitch-of-a-sound-is-proportional-to-the-frequency,-the-
perceived-pitch-of-the-sound-increases-as-the-vehicle-approaches-the-observer.
