When lava first breaks through the surface of the Earth, it is an extremely hot liquid. On average, fresh lava can be between 1,300Â° F and 2,200Â° F! Depending on its exact temperature, fresh lava usually glows either orange/red (cooler) or white (hotter). Eventually, lava cools and returns to solid rock again.
Eutrophication is the process of increase of plant nutrients in water with the consequent. increase in the growth of algae and higher plants. This process is facilitated by external. and internal (such as nitrogen fixation) sources of nutrients. Input of nutrients may be. from point or diffuse sources.
Iron overload is frequently present in PCT and may be associated with varying degrees of damage of the liver. A severe form of PCT, hepatoerythropoietic porphyria (HEP), has its onset in infancy with the accumulation of protoporphyrin in the red blood cells. The level of the enzyme UROD is very low in red cells. The UROD gene has been mapped to 1p34.
