Evolutionary condition when everywhere was surrounded by water. when the condition changed than sea water is going to boil and these animals get more fast metabolic reaction. we know when metabolic reaction going to fast then required oxygen quantity is more high and when water boils then mixed oxygen quantity is very less (due to hydrogen bonds breaking).
Now the time when early vertebrates came out from water because the condition would be changed there are direct oxygen in atmosphere from that they fulfill required oxygen.
A young baby frog is a tadpole. A tadpole is adapted to live in water. For breathing, it has gills, which helps it remain inside water until it grows up to become a frog. Gill are breathing organs of fish also, and the mode of living of a tadpole is similar to that of a fish. When it becomes a frog, it is capable of breathing both in air and in water. For breathing in air, a frog develops lungs and for breathing inside water the skin is used.
Breathing air through lungs Breathing Oxygen in water via gills Absorbing oxygen through the skin (mainly amphibians)
Yes, a lion is a vertebrate. It has a backbone and a skeleton, so therefore, it is a vertebrate.Yes, a lion is a vertebrate it has a backbone just like a cat.yes
amphibian
No, when they hatch out of eggs they are air-breathing and look like small turtles
No. Birds are air breathing vertebrates, there were no air breathing animals in the Precambrian. The earliest bird fossils are found in rocks about 160 million years old in the Jurassic period.
Snakes are cold-blooded, air breathing vertebrates that mostly reside on land and have scaly skin. These are all reptilian traits.
There are different rumours; however invertebrates are said not having bones, but some scientists do not recognize Agnathaas vertebrates; in this case, because some extint agnathes had osseous tissue, some invertebrates would be said to have bones.
Smog, hazy air, odd smells, dis-coloration, breathing troubles, "thick" air, plant life dying off.
Mammals are air-breathing vertebrates. In mammals, respiration takes place in the lungs. Parts of the respiratory system include the lungs, diaphragm, bronchioles, bronchi, and trachea.
If you mean 'respiratory system'.....then it starts at the nose (breathing in is the first process before the air can reach the lungs for filtering out of oxygen into the blood stream). Breathing in is referred to as inhalation (of air), and breathing out is exhalation. Try browsing through the Biology categories (Human Anatomy, etc.) for the technical details, if you need them.
it is because you need more air to exhale for excercising so thats why you begin to breath faster
The taxonomical class Mammals includes all animals (and people) that are air-breathing vertebrates, endothermic, have hair, three middle ear bones and in which females with you have functional mammary glands.
Air is used for breathing. Breathing is used to introduce oxygen into our system. Oxygen is necessary for life. Without breathing in air we would die.

You have the amphibians which are born in the water and grow into air breathing creatures, (such as the frog). Then there are the aquatic vertebrates which are wholly, or chiefly, water living creatures.
you breathing is out and in and that is the breathing is changes is
