Question

Match the parts of the fish to their correct functions.

a) Allow the fish to breathe underwater - Gills
b) Protects the fish from the external environment - Scales
c) Creates balance and helps with escape and predation - Fins

Answer 1

Gills are the respiratory organs in fish that extract oxygen from water. Fish scales protect the fish and reduce water resistance. Fins aid in balance, escape, and predation.

Step-by-step explanation:

Gills are the respiratory organs in fish that allow them to extract oxygen from water. They consist of many thin, folded tissues that provide a large surface area for oxygen uptake. When water passes over the gills, oxygen is absorbed and carbon dioxide is released.

Fish scales serve to protect the fish from the external environment. They cover the skin of the fish and provide a barrier against predators, parasites, and friction with the water. Scales also reduce water resistance when the fish is swimming, allowing for more efficient movement.

Fins in fish have multiple functions. They help create balance and stability, allowing the fish to maneuver and change direction in the water. Fins also aid in escape from predators and in capturing prey. Different types of fins, such as the caudal fin (tail fin) and pectoral fins, have specialized roles in propulsion and steering.
