Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions. 
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs. 
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
 
        
                    
             
        
        
        
Answer:
I believe the answer is A: Neveah's mass would stay the same but her weight would decrease
Explanation:
I believe its A because the moon has about 1/6 as much gravity as the Earth.  So if anything, her weight would decrease, not increase like B., C., or D says.  I hope this is helpful to anyone who reads it!!! ;)
