Answer:
Finally, the chemical messenger is taken back into the presynaptic neuron, ready to be used again. As levels of the neurotransmitter in the synapse decrease, the stimulation of the postsynaptic nerve ends.
Explanation:
The synapse is the space between two neurons. Through this space, neurons communicate.
An action potential causes the release of neurotransmitters from the presynaptic neuron; if there are enough of these specific neurotransmitters to bind to receptors on the postsynaptic neuron, they do and an action potential is now generated on this neuron.
This communication between two neurons must end once it's happened. In order for it to end, the synapse must be free of neurotransmitters. One mechanism to do so is for the neurotransmitters to be taken back into the presynaptic neuron.
Answer:
The given pedigree analysis shows sex-linked trait where the female work as a carrier and have X linked recessive gene that is 
and the male is normal.
So, Fred will be a male with 
gene and Fred will be affected with X linked disease which is carried by female.
If, gene in the female (Ann) act as a carrier of hemophilia and the male (John) is normal, then Fred will be a male affected with hemophilia (sex linked disease).
Hence, Fred will be affected male with genotype.
