Living cells generally can have any large dimension, except because materials must move into and out of the cell rapidly by diffusion. a) width  b) lengthc) volume  d) surface area

Living  cell    generally can  have any large  dimension   except volume.This  is  because  increase  in  volume  will  led  to more ratio  of  volume than  surface  area  which  means  there  will be  more  units  of  volume  for  each unit  surface area   which  make  substance to  take  longer  to diffuse  into  the  cell.

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.
