(1) Breathing involves the upward movement of diaphragm.O
(2) The fishes have lungs for respiration.​

Answer 1

Answer:

1. true

2. false

Explanation:

1.A large dome-shaped muscle under the lungs called the diaphragm squeezes downward when you breathe in, making a vacuum that causes a rush of fresh air into your lungs. The opposite happens when you breathe out -- your diaphragm relaxes upward, pushing on your lungs, letting them deflate.

2.Unlike land animals, which have lungs to take in oxygen from the air, fish have gills to breathe in the oxygen contained in water. This process of breathing begins when a fish gulps water through its mouth.
