You investigated the cytoskeleton and found that all three elements, including the one you suspected, are completely normal. you then decide to look at the motor proteins to see if the cause might lie with one of them. which of the following would be your hypothesis?

Based on the information give, the most probable answer to this question is that "motor proteins of cells are causing dysfunction responses and activities inside the cell."Thank you for your question. Please don't hesitate to ask in your queries. 

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
