The number of phenotypes produced for a given trait depends on the number of genes that control that trait. so the answer is 1
        
                    
             
        
        
        
Answer: True 
Explanation:
The neuron has leak channels in the cell body, axon and dendrite and cell body. This is because the trans membrane potential exists in all parts of the cell membrane.
Because of this reason the the leak channels are available at each part of the neuron.
The action potential, trans membrane potential should exits in all the parts of the cell so it should be located in all the parts of cell. 
 
        
             
        
        
        
Assuming this is multiple choice, the answer would be "niche". An organism's niche is where that certain organism fits into an ecosystem, or what their part to play is.
