E) none of the above
The answer is C) positive pressure breathing
Explanation:
Mammals such as humans and goats possess diaphragms . The muscles of the diaphragm create a type of pressure which helps in pulling air into the lungs. This process is called Negative pressure breathing.
Amphibians lack diaphragms so they lack pressure to draw air into the lungs , it is forced into the lungs instead in a process known as positive pressure breathing.
