Frequency describes the number of waves that pass a fixed place in a given amount of time.
<span>The lungs are the organs that are most crucial in
expelling cellular carbon dioxide waste. Lungs are the most important organ of
the respiratory system. They excrete these wastes through the process of
diffusion and exhalation. Without the proper excretion of carbon dioxide by the
lungs, the blood will be left without oxygen and might be toxic to course
through the bloodstream. The lungs are responsible for converting unoxygenated
blood into oxygenated blood. Through this process carbon dioxide is expelled as
the by-product.</span>
Ring species.
When there are neighbouring populations that can interbreed with each other while only two of those populations cannot breed between them, we are standing before a ring species. In the case of Larus gulls what is observed is that several of these species can interbreed, but it comes to two of them that are incompatible - they are probably to<span> distantly related to interbreed. It is considered, that this species may be connected to each other in a line of derivation and is both ends on that line that are incompatible.</span>
