Question 1
Which of the following best describes the reaction NaNO3 + HCl →
HNO3 + NaCl?
A. Synthesis reaction
B. Decomposition reaction
C. Exchange reaction
D. Combustion reaction
Answer: C. Exchange reaction
Rationale: In this reaction, the cations and anions of two compounds
switch places. NaNO3 exchanges its Na⁺ with H⁺ from HCl to form HNO3
and NaCl, which is characteristic of an exchange reaction.
Question 2

The function of the association area in the frontal lobe is:
A. Regulating heart rate
B. Controlling voluntary movement
C. Higher intellectual processes, such as reasoning and judgment
D. Processing visual input
Answer: C. Higher intellectual processes, such as reasoning and
judgment
Rationale: Association areas integrate information from multiple
regions of the brain. In the frontal lobe, they are responsible for
complex cognition, planning, decision-making, and personality
expression.
Question 3
Cerebrospinal fluid (CSF) is produced by ______ and its function is
______.
A. Choroid plexuses in the ventricles; protects the brain from blows to
the skull
B. Hypothalamus; controls body temperature
C. Pineal gland; regulates sleep cycles
D. Medulla oblongata; controls heart rate
,3|Page
Answer: A. Choroid plexuses in the ventricles; protects the brain from
blows to the skull
Rationale: CSF is secreted by the choroid plexuses, which are specialized
networks of capillaries in the ventricles. It cushions the brain, maintains
chemical stability, and removes metabolic waste.
Question 4
The anaerobic reactions of cellular respiration occur in the ______,
whereas the aerobic reactions occur in the ______.
A. Nucleus; mitochondria
B. Cytoplasm without O2 required; mitochondria with O2 required
C. Ribosome; endoplasmic reticulum
D. Golgi apparatus; lysosomes
Answer: B. Cytoplasm without O2 required; mitochondria with O2
required
Rationale: Glycolysis (anaerobic) occurs in the cytoplasm and does not
require oxygen. The Krebs cycle and electron transport chain (aerobic)
occur in the mitochondria and require oxygen to generate ATP
efficiently.
Question 5
, 4|Page
A pole vaulter keeps track of his position in mid-air through:
A. Photoreceptors
B. Mechanoreceptors
C. Proprioceptors
D. Nociceptors
Answer: C. Proprioceptors
Rationale: Proprioceptors provide feedback on the position and
movement of the body in space, allowing athletes like pole vaulters to
maintain balance and coordination mid-air.
Question 6
Epithelial tissue functions in:
A. Conduction of nerve impulses
B. Support and structure
C. Secretion, absorption, and protection
D. Storage of fat
Answer: C. Secretion, absorption, and protection
Rationale: Epithelial tissue lines surfaces and cavities, forming barriers.
It specializes in absorbing nutrients, secreting substances like enzymes
