Specifically, the oxyhemoglobin dissociation curve relates oxygen saturation (S. 2) and partial pressure of oxygen in the blood (P. 2), and is determined by what is called hemoglobin affinity for oxygen; that is, how readily hemoglobin acquires and releases oxygen molecules into the fluid that surrounds it.March 2009). The oxygenâhemoglobin dissociation curve, also called the oxyhemoglobin dissociation curve or oxygen dissociation curve (ODC), is a curve that plots the proportion of hemoglobin in its saturated (oxygen-laden) form on the vertical axis against the prevailing oxygen tension on the horizontal axis.
The Mayas believed in a world of three layers: Heaven, the middle world, and underworld. Its roots were in the underworld, its trunk in the middle world, and its branches in the highest layer of the other world.
Theres a story in Mayan mythology of the first beings being made of gypsum (stories change from tribe to tribe but the story is predominantly the same). That there existed a group of beings made by the gods who were made of clay sometimes gypsum then they got washed away by a flood.
