Question

why can some insects walk on water while humans cannot? 5 points insects have special waterproof feet surface tension from hydrogen bonding creates a resistant film strong enough for light insects water molecules repel insect feet insects manipulate water polarity why does ice float on liquid water? 5 points ice contains air bubbles that make it lighter liquid water is naturally more dense than all solids ice molecules move faster than liquid water molecules hydrogen bonds keep water molecules farther apart in ice, making it less dense

Explanation:

For the first question, surface tension due to hydrogen - bonding in water creates a thin, resistant film that can support the weight of light insects. For the second question, in ice, hydrogen bonds hold water molecules in a more spread - out lattice structure, making ice less dense than liquid water, so it floats.

Answer:

1. B. Surface tension from hydrogen bonding creates a resistant film strong enough for light insects
2. D. Hydrogen bonds keep water molecules farther apart in ice, making it less dense
