Many fish, such as the perch shown above, have long bodies that are tapered at both ends. What is the function of this streamlined body shape?

A.
It warns predators that the fish are poisonous.
B.
It helps keep the fish from getting bacterial infections.
C.
It enables the fish to blend in with other types of marine life.
D.
It allows the fish to swim quickly and efficiently

D. It allows the fish to swim quickly and efficiently

D. It allows the fish to swim quickly and efficiently

The streamlined body shape of fish like the perch serves the function of allowing them to swim quickly and efficiently. This body shape reduces drag as the fish moves through the water, enabling them to swim faster with less resistance.

To get the answer to this question, you can observe and analyze the characteristics and behaviors of fish with streamlined bodies, such as the perch. By studying the physical traits of these fish and their swimming abilities, you can deduce that their body shape is advantageous for swift and efficient movement in water. Additionally, knowledge of basic biological concepts related to fish anatomy and ecology can provide further evidence supporting the function of a streamlined body shape for fast swimming.
