Question

a water strider can skate along the top of a pond because: covalent bonds result in water cohesion (surface tension); water striders are afraid of water and avoid it; water striders have adapted to take advantage of water cohesion; hydrogen bonds result in water cohesion (surface tension)

Explanation:

Water striders skate on water due to surface tension from water cohesion. Hydrogen bonds between water molecules create cohesion (surface tension), not covalent bonds. The other options are illogical (fear of water) or less accurate (adaptation is secondary to the physical property).

Answer:

D. hydrogen bonds result in water cohesion (surface tension)
