Answer: True
Explanation: The typical synapse in the Central Nervous System (CNS) consists of 3 parts namely:
1) 'The Presynaptic Neuron' formed by the terminal button of an axon
2) 'The Postsynaptic Neuron' made up of segments of dendrite or cell body
3) 'The Synaptic Cleft' which is the space between the presynaptic neuron and postsynaptic neuron.
The 'Central Nervous system (CNS)' is made up of the brain and spinal cord.
A 'Synapse' is a junction between two nerve cells. It transfers information from one cell to another either by 'diffusion' or through 'neurotransmission'. The transfer of information can be from nerve to nerve or nerve to muscle.
The 'Presynaptic Neuron' is a nerve cell that fires the neurotransmitter. In other words, it delivers messages (neurotransmission) across the synapse. The 'Postsynapse' is the receiver of the neurotransmission which is the message.

Answer:
B) The inhibition of normal myelin development in the individual's brain
Explanation:
Phenylketonuria is a disorder characterized by abnormal levels of phenylalanine in the body. It is <u>caused by mutation in DNA that leads to the deficiency of an enzyme known as phenylalanine hydroxylase, which converts phenylalanine to tyrosine</u>, a fundamental substance for dopamine production - related to working memory.
Some of the symptoms of this disorder is intellectual disability, which is caused mainly by demyelination or defective myelin biosynthesis, leading to the <u>inhibition of myelin, a fatty insulating sheath that protects nerves</u>.
Therefore, the cause of the intellectual disability in the individual is <u>the inhibition of normal myelin development in the individual's brain.</u>
