2024 QUESTIONS AND CORRECT DETAILED
ANSWERS| A+
Section 1: General Science (GS)
1. Which of the following is the most abundant gas in Earth's atmosphere?
A. Oxygen
B. Carbon Dioxide
C. Nitrogen
D. Argon
Correct Answer: C. Nitrogen
Rationale: Earth's atmosphere is composed of approximately 78% nitrogen,
21% oxygen, 0.9% argon, and 0.04% carbon dioxide. Nitrogen is by far the most
abundant.
2. What is the primary function of red blood cells?
A. To fight infection
B. To transport oxygen
C. To clot blood
D. To produce antibodies
Correct Answer: B. To transport oxygen
Rationale: Red blood cells contain hemoglobin, a protein that binds to oxygen
in the lungs and transports it to tissues throughout the body. White blood cells
fight infection, and platelets help with clotting.
3. Which planet in our solar system is known as the "Red Planet"?
A. Venus
B. Jupiter
C. Mars
D. Saturn
, Correct Answer: C. Mars
Rationale: Mars is called the Red Planet because iron minerals in its soil
oxidize, or rust, causing the surface to look red.
4. What is the chemical symbol for water?
A. CO2
B. O2
C. H2O
D. NaCl
Correct Answer: C. H2O
Rationale: A water molecule is composed of two hydrogen atoms (H) and one
oxygen atom (O), giving it the chemical formula H2O.
5. Which of the following is a renewable resource?
A. Coal
B. Natural Gas
C. Solar Energy
D. Petroleum
Correct Answer: C. Solar Energy
Rationale: Solar energy is renewable because it is naturally replenished. Coal,
natural gas, and petroleum are fossil fuels, which are non-renewable resources
that take millions of years to form.
6. What is the powerhouse of the cell?
A. Nucleus
B. Ribosome
C. Mitochondria
D. Cell Membrane
Correct Answer: C. Mitochondria
Rationale: Mitochondria are organelles responsible for producing energy in
the form of ATP through cellular respiration. They are often called the
"powerhouse" of the cell.
,7. Which of the following is NOT a state of matter?
A. Solid
B. Liquid
C. Gas
D. Energy
Correct Answer: D. Energy
Rationale: The three primary states of matter are solid, liquid, and gas (plasma
is a fourth). Energy is not a state of matter; it is a property that can cause changes
in matter.
8. What force keeps the planets in orbit around the Sun?
A. Electromagnetism
B. Gravity
C. Nuclear Force
D. Friction
Correct Answer: B. Gravity
Rationale: Gravity is the attractive force between objects with mass. The Sun's
immense gravity pulls on the planets, keeping them in their orbital paths.
9. Which of the following is a function of the skeletal system?
A. Producing hormones
B. Transporting nutrients
C. Protecting vital organs
D. Filtering blood
Correct Answer: C. Protecting vital organs
Rationale: The skeletal system provides support and protection for internal
organs (e.g., the skull protects the brain, the rib cage protects the heart and
lungs), allows for movement, and produces blood cells.
10. What type of chemical bond involves the sharing of electron pairs between
atoms?
A. Ionic bond
, B. Covalent bond
C. Hydrogen bond
D. Metallic bond
Correct Answer: B. Covalent bond
Rationale: A covalent bond is formed when two atoms share one or more
pairs of electrons. An ionic bond involves the transfer of electrons.
11. Which part of the plant is primarily responsible for photosynthesis?
A. Roots
B. Stem
C. Leaves
D. Flowers
Correct Answer: C. Leaves
Rationale: Leaves contain chlorophyll and are the primary site of
photosynthesis, where plants convert sunlight, water, and carbon dioxide into
glucose and oxygen.
12. What is the hardest natural substance on Earth?
A. Gold
B. Iron
C. Diamond
D. Quartz
Correct Answer: C. Diamond
Rationale: Diamond is a form of carbon with a very strong crystalline lattice
structure, making it the hardest known naturally occurring mineral.
13. Which of the following best describes a mammal? (Select All That Apply)
A. Has feathers
B. Warm-blooded
C. Produces milk for its young
D. Lays hard-shelled eggs
