the gecko a small lizard can climb up a smooth glass window, the gecko has million of microscopic hairs on its toes and each hair has thousands if pads its tip. the result is that the molecules in the pads. are extremely close to the glass surface on which the gecko is climbing what is the attraction between then gecko toe pads and the glass surface?
A) coordinate bond
B) covalent bond
C) ionic bond
D) vander waals forces

Question

the gecko a small lizard can climb up a smooth glass window, the gecko has million of microscopic hairs on its toes and each hair has thousands if pads its tip. the result is that the molecules in the pads. are extremely close to the glass surface on which the gecko is climbing what is the attraction between then gecko toe pads and the glass surface?
A) coordinate bond
B) covalent bond
C) ionic bond
D) vander waals forces

anonymous · Answer

D) vander waals forces
these forces(attractive) act between two molecules or atoms as a result of their size.this force increases with the increase in size of the particle

abmon98 · Answer

Whenever the lizard attaches it's feet more to the surface force increases, could you explain not in terms but within the question

anonymous · Answer

this attractive force increases with decrease in distance

anonymous · Answer

attractive force increases with decrease in distance....

abmon98 · Answer

But why did you choose vander waals other than the other bond

anonymous · Answer

other those bonds involve sharing or transfer of electrons,due to which a very strong and permanent bond is formed.these other bonds  are the reason molecules and atoms react to form new type of molecules and compounds

D: vander waals forces heres a link to explain more in detail.: http://www.science.gov/topicpages/g/geckos+gekko+tawaensis.html
