(9) Histochemical profiles and capillarisation data of the red and white muscle were compared to those of less active demersal species.
(10) Contrasting environmental conditions during embryogenesis of these two species may be reflected by the thin membrane and simple lamellar structure in the pelagic egg of the starry flounder, and the thick membrane and complex lamellar structure in the demersal egg of the pink salmon.
(11) When released into seawater, spermatozeugmata retain their structural integrity for varying periods (up to 24 hours) and become demersally distributed in still water.
(12) When gut samples were examined, the incidence was highest in demersal fish (cod and flatfish) as compared with pelagic fish (herring).
Submersed
Definition:
(a.) Being or growing under water, as the leaves of aquatic plants.
Example Sentences:

(4) The whole animal showed a constrictor response during submersion, with the sciatic vascular bed showing average constriction.
(5) The keratin pattern noted indicated that these epithelia differentiate and keratinize but do not express a complete program of keratinization, a finding usually noted when cells are grown submersed.
(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.

(18) Forty brine samples used for submersion salting of mozzarella cheese in a dairy industry in the State of S. Paulo, Brazil, were analysed for the purpose of discovering the variation in the physical, chemical and microbiological characteristics observed over their period of utilization.
(19) It is concluded that stimulation of adrenergic alpha-receptors is responsible for the increase in resistance to flow through the sciatic artery and the maintenance of blood pressure during submersion in the normal animals.
