Answer:
Neurotransmitters are released from axon terminals via exocytosis
Explanation:
Dendrite is the receiving part of the presynaptic neuron, while axon is the transmitting part of the neuron. So, after initiation, action potentials travel down axons to the terminals. Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells (exocytosis of the vesicle's content). Neurotransmitter ACh (from the vesicles) binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.
 
        
             
        
        
        
The correct answer would be option D, that is, fertilization during the study.  
The experimental error refers to the dissimilarity between a measurement and the true value or between the two measured values. Experimental error is determined by its accuracy and precision.  
A variation in data, or error, basically signifies whatever results in the data to be imperfect, not the human mistakes. In order to correct this, there is a need to get familiar with the unavoidable sources of error and how they take place so that one can reduce their effect and get the best probable data.
