Verified
The water strider is an insect that skates across the water without sinking. The tips of its feet must be coated with molecules that are
A) ions.
B) hydrophilic.
C) hydrophobic.
D) basic.
E) acidic.
Hydrophilic
Describing molecules or substances that have a natural affinity for water and can dissolve in or absorb water easily.
Hydrophobic
A characteristic of molecules or substances that do not readily mix with or are repelled by water, often due to nonpolar characteristics.
Water Strider
An insect that can walk on the surface of water due to the high surface tension of water and the long, water-repellent legs of the insect.
- Acknowledge the singular attributes of water attributed to hydrogen bonds, like cohesion, surface tension, and the lesser density of ice compared to liquid water.

Final Answer :
C
Explanation :
The water strider's ability to skate across water is due to the hydrophobic (water-repelling) coating on the tips of its feet. This allows it to walk on the water's surface without breaking the surface tension.
