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 Correct Answer: (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 Correct Answer: (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.
Correct Answer: (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 Correct Answer: (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 Correct Answer: (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 Correct Answer: (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 Correct Answer: (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 Correct Answer: (D) Destroy
bacteria through an oxidation reaction.
