(18) The investigations reported here with higher and particularly emersed plants, show what an astonishing influence the higher plants exert on organic and inorganic matter, on pH regulation, destruction of pathogenic bacteria, worms' eggs, and viruses, and also how they influence the waters and waste waters.
(19) The time course of blood acid-base changes was studied in Carcinus maenas during experimental emersion and reimmersion at 15 degrees C by measuring pH and PCO2 and calculating bicarbonate concentration.
(20) During the alternation between air breathing (emersion) and apneic phases (immersion), the pattern of the circulation in the lungfish oscillates between that of a tetrapod and a fish.
Submersed
Definition:
(a.) Being or growing under water, as the leaves of aquatic plants.
Example Sentences:

(6) To analyze prognostic indicators and the outcome of resuscitation in submersion victims (drowning and near drowning).
(7) Heart rate during submersion was unaffected by inspired gas composition in control (data from intact and sham-operated ducks combined) and CB-denervated ducks, though diving behaviour was significantly modified in both groups of animals in response to altered inspired gas composition.
(8) To prepare debris from polyethylene, a stainless steel block was rubbed over a polyethylene block submersed in liquid nitrogen.
(9) Because alcohol is often involved in water accidents with associated submersions, these initial experiments dealt with human volunteers who consumed alcohol to a blood level of 0.1 g% (legal level of intoxication).
(10) boy suffered cardiac arrest after submersion in a winter pond for more than fifteen minutes.
(11) Heart rate during overnight rest and while diving were recorded from five emperor penguins with a microprocessor-controlled submersible recorder.
