Question

some insects can walk on the surface of water because water multiple choice is a good solvent. resists temperature changes. has a high specific heat. has a lower density when frozen. has surface tension.

Explanation:

Insects walking on water is due to water's surface tension. Surface tension is the cohesive force between liquid molecules at the surface, creating a "skin" that can support light objects like some insects. The other options (good solvent, resisting temp changes, high specific heat, lower density when frozen) don't relate to supporting objects on the water surface.

Answer:

has surface tension.
