Explanation:

Neurotransmitters transmit the electric signal from the neuron to another neuron or an effector cell which is the target cell like the muscles or the glands. Receptors are transducers which connect with the external and internal environment and carry the nerve signals.

The neuromuscular junction refers to the synaptic connection between a nerve cell and a muscle cell. The primary receptor at the neuromuscular junction is the nicotinic acetylcholine receptors which respond to acetylcholine neurotransmitters.  

The parasympathetic nervous system works with muscuranic receptors which are activated by acetylcholine. These receptors transducts the neurosignals (chlorinergic) in the parasympathetic end organs.

The sympathetic nervous system is associated with the adrenergic receptors and activated by epinephrine or norephinephrine and controls blood flow in the vessels.  

the backbone of the dna and rna compound is sugar phosphate.

the answer is sex-linked recessive.
