Lungfishes have poor but existent lung-like organs. Actually they're air sacs but they essentially do the same job as lungs. This means that the lungfish is able to rise to the surface of the water and quickly breath in some air instead of filtering the oxygen out of a body of water where there is none.
Because they can.
It can supplement its oxygen by using oxygen from air as well as water.
no. she was one of the unfortunate children who died. poor girl.
oxygen poor
Oxygen poor blood
Venous blood is oxygen poor (in comparison with arterial blood).
Pure water is a poor conductor of electricity because it does not contain ions that can carry an electric current. Oxygen is also a poor conductor of electricity because it is a non-metal element that does not have free electrons to move and carry charge.
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
poor
No, oxygen itself is not a good conductor of electricity, even when mixed with water. Water itself is a poor conductor of electricity, unless it contains dissolved ions or impurities that can carry electrical charge.
poor
Like all fish they breathe through their gills, thus getting oxygen (air) from the water, they do not need to surface for air unless the water had a poor oxygen level.
