Aquatic organisms are usually more streamlined than terrestrial organisms because of water's high
A)buoyancy.
B)viscosity.
C)surface tension.
D)density.

Question

Quizplus · Accepted Answer

Water is more viscous (thick and resistant to flow) than air, so aquatic organisms have evolved streamlined shapes to reduce drag and move more efficiently through the water. Buoyancy (A) can also affect the shape of aquatic organisms, but it does not necessarily make them more streamlined. Surface tension (C) and density (D) do not directly relate to the streamlining of aquatic organisms.
