Sentences with phrase «where oxygen concentrations»

This includes places like parts of the eastern Pacific Ocean where small animals like nematodes and specially adapted fish live on the fringes of habitability, subsisting in waters where oxygen concentrations can be only about 1 % of normal surface water levels.

Not exact matches

Landon was diagnosed with hypernatremic dehydration (a high concentration of sodium in the blood), cardiac arrest from hypovolemic shock (a condition where the liquid portion of the blood is dangerously low), and hypoxic - ischemic encephalopathy (a brain injury caused by oxygen deprivation).

In places where sea - floor oxygen levels are a bit higher — about 0.5 — 3 % of concentrations at the sea surface — animals are more abundant but their food webs remain limited: the animals still feed on microbes rather than on each other.

To isolate the effects of oxygen concentration, researchers from the University of Colorado compared the rate of SIDS in infants living at high altitudes, where the air is thin, to those living closer to sea level.

Using molecular beam epitaxy, a well - known technique from semiconductor technology, the group was able to produce RRAM structures where only the oxygen concentration was varied while all the rest of the device was identical.

Researchers have discovered the molecular mechanisms by which the roundworm C. elegans senses oxygen concentrations in the highly variable soil environment where it lives.

Hypoxia, or low oxygen, is an environmental phenomenon where the concentration of dissolved oxygen in the water column decreases to a level that can no longer support living aquatic organisms.

This is because hydrate decomposition primarily occurs in the Pacific Ocean, where present - day seawater has low oxygen concentration.
