Question 2

Why is the surface area of a gecko's foot so extensive?
 
  A) A gecko, like all amphibians, needs extensive surface area under foot for stability on land as well as mobility in water.
  B) A gecko's foot acts like a large dipole and thus allows for ion-dipole interaction in water.
  C) The greater the surface area the greater the number of induced dipole-induced dipole forces of attraction that can occur between the gecko's foot and the surface.
  D) The extensive surface area, once charged by the gecko's body, allows for the dipole-dipole attraction of every contact surface.
