The correct answer is: prevent reception of a signal in a receiving neuron
Neurotransmitters are signal molecules or chemical messengers which transmit signals across a chemical synapse. Neurotransmitters send the signal, from one neuron (nerve cell) to another neuron, from neuron to muscle cell (motor plate), or from neuron to gland cell.
Drugs that bind to neurotransmitter’s receptor can have two effects on its action:
•	Antagonists-they bind to receptor and thus prevent a neurotransmitter from binding to it
•	Agonists-they bind to receptor and mimic the normal neurotransmitter (have the same effect as neurotransmitter).
 
        
             
        
        
        
Good afternoon. An organelle is any structure in cells that has a specialized function. They are usually found in eukaryotic (nucleus) cells. They help with energy, making proteins, and removing wastes from a certain area. They are composed of large molecules such as proteins, carbohydrates, lipids, and nucleic acids. I hope I helped!! If you have any more questions then don't hesitate to let me know. Have a great day!!
 
        
                    
             
        
        
        
Answer:
The correct option is D) All of the answers are correct.
Explanation:
The walls of the capillaries are thin due to which the processes of diffusion and filtration becomes lot easier in them. Gases such as oxygen and carbon dioxide cross the capillary walls through diffusion processes. As the walls of the capillaries are much thinner than that of veins and arteries hence. the processes of filtration and re absorption occur easily through them.
