A feeding adaptation an iguana has is it’s short nose. This feature is important for feeding because it helps it eat algae off rocks.
Marine and Land iguanas have similar traits even though they aren’t the same kind of iguana because, most of their predators are the same. Therefore a bird or other prey would not be able to tell the difference so that’s why land and marine would both need spines on their back.
I think the camouflage is the most beneficial in land iguanas because their predators can’t spot them that easily, and it’s a quick way to blend in. I also think that the iguanas nose on marine iguanas is the most important because when they eat algae it’s easy to eat and they don’t have to change their position when feeding.
When organisms mate without human interference, it is called natural selection.
Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. This is called dead air space.
Alveoli are the tiny air sacs present all over the lungs. These are supposed to increase the surface area of the lungs so as to increase the amount of inhaled air. The exchange of oxygen and carbon dioxide takes place through these alveoli.
Dead air space is the unventilated area where air circulation does not take place. This air is supposed to be get trapped somewhere in the respiratory pathway or it reaches an alveoli that is poorly perfused. The dead air space can be of two types: anatomical dead space and physiologic dead space.
