true
false
The respiratory structures which adapt in different surroundings include moist outer skin, gills and trachea
true
false
Animal X is an organism that can only live in water. Therefore, the respiratory structure of animal X, namely gills can adapt to increase the efficiency of gaseous exchange in water.Animal X is
frog
grasshopper
fish
whale

spiracles
spiral
spirit
stoma
