Q1. Which organelle is responsible for producing ATP through cellular respiration?
A. Nucleus
B. Ribosome
C. Mitochondria
D. Golgi apparatus
Correct Answer: C
C. Mitochondria [CORRECT]
Rationale: Mitochondria are the "powerhouses" of the cell, producing ATP via the
Krebs cycle and electron transport chain. A is incorrect because the nucleus houses
DNA. B is incorrect because ribosomes synthesize proteins. D is incorrect because the
Golgi apparatus modifies and packages proteins. ASVAB Strategy: Remember
"Mighty Mitochondria Make ATP"—this is one of the most tested biology concepts.
Q2. In the human digestive system, where does most nutrient absorption occur?
A. Stomach
B. Large intestine
,C. Small intestine
D. Esophagus
Correct Answer: C
C. Small intestine [CORRECT]
Rationale: The small intestine, with its villi and microvilli, provides massive surface
area for nutrient absorption. A is incorrect because the stomach primarily breaks
down food mechanically and chemically. B is incorrect because the large intestine
mainly absorbs water and electrolytes. D is incorrect because the esophagus only
transports food. ASVAB Strategy: The small intestine's villi are the key feature—
always associate villi with absorption.
Q3. What is the chemical formula for glucose?
A. C₆H₁₂O₆
B. C₁₂H₂₂O₁₁
C. CH₄
D. CO₂
Correct Answer: A
A. C₆H₁₂O₆ [CORRECT]
Rationale: Glucose is a monosaccharide with the formula C₆H₁₂O₆. B is incorrect
because C₁₂H₂₂O₁₁ is sucrose (table sugar). C is incorrect because CH₄ is methane. D
is incorrect because CO₂ is carbon dioxide. ASVAB Strategy: Memorize key biological
molecules: glucose C₆H₁₂O₆, water H₂O, carbon dioxide CO₂.
Q4. Which of the following is a noble gas?
A. Oxygen
B. Nitrogen
C. Argon
D. Chlorine
,Correct Answer: C
C. Argon [CORRECT]
Rationale: Argon (Ar) is in Group 18 of the periodic table, the noble gases,
characterized by full valence electron shells. A is incorrect because oxygen is in
Group 16. B is incorrect because nitrogen is in Group 15. D is incorrect because
chlorine is a halogen in Group 17. ASVAB Strategy: Noble gases are He, Ne, Ar, Kr,
Xe, Rn—remember "He Never Argues, Kills Xenon Rabbits" or just know Group 18.
Q5. What type of bond forms when electrons are shared between atoms?
A. Ionic bond
B. Covalent bond
C. Hydrogen bond
D. Metallic bond
Correct Answer: B
B. Covalent bond [CORRECT]
Rationale: Covalent bonds involve the sharing of electron pairs between atoms. A is
incorrect because ionic bonds involve electron transfer, creating charged ions. C is
incorrect because hydrogen bonds are weak attractions between molecules, not true
chemical bonds. D is incorrect because metallic bonds involve a "sea" of delocalized
electrons among metal atoms. ASVAB Strategy: "Share = Covalent, Transfer =
Ionic"—this distinction is tested repeatedly.
Q6. According to Newton's Third Law of Motion, for every action there is:
A. An equal and opposite reaction
B. A greater reaction in the direction of motion
C. No reaction if the object is at rest
D. A reaction only in a vacuum
Correct Answer: A
, A. An equal and opposite reaction [CORRECT]
Rationale: Newton's Third Law states that for every action force, there is an equal
and opposite reaction force. B is incorrect because reactions are equal, not greater. C
is incorrect because the law applies regardless of motion state. D is incorrect because
the law applies in all environments. ASVAB Strategy: Newton's Three Laws are high-
frequency topics: 1st (inertia), 2nd (F=ma), 3rd (action-reaction).
Q7. What is the primary function of red blood cells?
A. Fight infection
B. Transport oxygen
C. Clot blood
D. Produce antibodies
Correct Answer: B
B. Transport oxygen [CORRECT]
Rationale: Red blood cells contain hemoglobin, which binds and transports oxygen
from the lungs to tissues. A is incorrect because white blood cells fight infection. C is
incorrect because platelets are responsible for clotting. D is incorrect because
antibodies are produced by B-lymphocytes, not red blood cells. ASVAB Strategy: Red
= Oxygen (hemoglobin), White = Infection (immune response), Platelets = Clotting.
Q8. Which layer of the Earth is composed primarily of liquid iron and nickel?
A. Crust
B. Mantle
C. Outer core
D. Inner core
Correct Answer: C
C. Outer core [CORRECT]
