,1. Which of the following is a key difference between monozygotic
and dizygotic twins in genetic studies?
A) Monozygotic twins have different genetic makeups.
B) Dizygotic twins share the same environment.
C) Monozygotic twins are identical, sharing 100% of their genes.
D) Dizygotic twins have identical chromosomes.
Correct Answer: C
Rationale: Monozygotic twins are identical, meaning they develop
from a single zygote that splits and forms two embryos, sharing
100% of their genes. This is in contrast to dizygotic twins, who
develop from two separate eggs and sperm, sharing about 50% of
their genes, similar to siblings.
2. In the context of the nervous system, what does the term
'neuroplasticity' refer to?
A) The ability of the nervous system to change its activity in
response to intrinsic or extrinsic stimuli.
B) The elasticity of the neural membranes.
C) The plastic or artificial components used in neural surgery.
D) The unchangeable nature of the adult brain.
Correct Answer: A
©2024/2025
, Rationale: Neuroplasticity is the capacity of neurons and neural
networks in the brain to change their connections and behavior in
response to new information, sensory stimulation, development,
damage, or dysfunction.
3. Which hormone is primarily involved in the fight-or-flight
response?
A) Insulin
B) Estrogen
C) Adrenaline
D) Oxytocin
Correct Answer: C
Rationale: Adrenaline, also known as epinephrine, is the
hormone secreted by the adrenal glands that plays a significant role
in the fight-or-flight response by increasing heart rate, blood
pressure, and energy supplies.
4. The occipital lobe of the brain is primarily responsible for which
function?
A) Auditory processing
B) Balance and coordination
C) Visual processing
D) Language comprehension

, Correct Answer: C
Rationale: The occipital lobe, located at the back of the brain, is
primarily responsible for visual processing and interpretation.
5. What is the primary function of the myelin sheath in a neuron?
A) To generate electrical impulses
B) To protect the neuron's nucleus
C) To speed up the transmission of electrical impulses along the
axon
D) To receive signals from other neurons
Correct Answer: C
Rationale: The myelin sheath is a fatty layer that covers the axon
of many neurons, acting as an insulator to greatly increase the
speed at which electrical impulses propagate along the axon.
Question 1:
Which of the following is NOT a neurotransmitter?
(a) Acetylcholine
(b) Dopamine
