11. In 1992, a pneumonia infection resulted in anoxia , and ultimately cost Jennings his vision again. 12. The consumption of this newly abundant organic life by aerobic bacteria would produce anoxia and mass extinction. 13. Therefore, " Chondrites " can be used as an indicator of anoxia in sediments. 14. But these theorists could never explain how anoxia might have caused the particular patterns that the extinctions took. 15. If this situation is not immediately identified and corrected, death will ensue from cerebral and cardiac anoxia . 16. It combines with haemoglobin when inhaled, so the victim dies of anoxia ( lack of oxygen ). 17. Variables that are considered, and often summarized by researchers, include : anoxia ; hypercarbia; the NMDA receptor; 18. In the oceans were massive reefs built by corals and anoxia , possibly triggered by global cooling or oceanic volcanism. 19. Isorenieratene and its derivatives are useful to marine chemists studying the carbon cycle as biomarkers that indicate photic zone anoxia . 20. Hypoxia in which there is complete deprivation of oxygen supply is referred to as "'anoxia " '.
