one of waters unique properties is that it has strong surface tension. what do you predict would happen if water had weak surface tension?
a insects would not be able to land on or walk on water.
b plants would not be able to draw water from the ground through their roots.
c water molecules would attract each other.
d water would only be able to dissolve nonpolar substances.

Explanation:

Surface tension allows insects to walk on water as it creates a 'skin - like' surface. If surface tension is weak, this supportive surface for insects would not exist. Plants drawing water from the ground is due to cohesion and adhesion (not directly surface tension), water molecules always attract each other due to hydrogen - bonding regardless of surface - tension strength, and water dissolves polar substances well due to its polarity, not related to surface tension.

Answer:

A. Insects would not be able to land on or walk on water.
