Questions, Answers & Detailed
Explanations
1. What is the major force that changes peat to coal?
a) Lift
b) Friction
c) Tension
d) Pressure
Answer: d) Pressure
Rationale: Peat is transformed into coal through a process called
coalification, which involves the application of intense pressure and
heat over millions of years. As layers of sediment accumulate above the
peat, the increasing pressure compacts the organic material, driving off
water and volatile compounds, and progressively converting it to
lignite, then bituminous coal, and eventually anthracite. Lift, friction,
and tension are not the primary forces responsible for this geological
transformation.
,2. Which occupation would most likely be involved in genome
mapping?
a) Gerontologist
b) Geneticist
c) Geophysicist
d) Geologist
Answer: b) Geneticist
Rationale: Genome mapping is the process of determining the location
of genes on a chromosome and the distances between them. This is a
core area of study in genetics, which is the branch of biology concerned
with heredity and variation in organisms. A geneticist specializes in this
field. A gerontologist studies aging, a geophysicist studies the physical
properties of the Earth, and a geologist studies rocks and Earth
history—none of which directly involve genome mapping.
3. Which of the following terms is used to describe an
organism's tendency to maintain its ideal internal state
relative to properties such as temperature and pH?
a) Mitosis
b) Adaptation
, c) Homeostasis
d) Conservation
Answer: c) Homeostasis
Rationale: Homeostasis is the biological process by which living
organisms maintain a stable internal environment despite changes in
external conditions. This includes regulating temperature, pH, water
balance, and other physiological variables within narrow limits. Mitosis
is cell division, adaptation refers to evolutionary changes over
generations, and conservation generally refers to resource protection—
not internal regulation.
4. Which of the following would likely be involved in
computing the stress on a building?
a) Cryogenics
b) Aerodynamics
c) Thermodynamics
d) Electromagnetics
Answer: b) Aerodynamics
Rationale: When computing the stress on a building, engineers must
consider forces such as wind loads. Aerodynamics is the study of how
