Answer :
Surfactant deficiency due to undeveloped lungs (in premature infants) suggest respiratory distress in an infant, but would be less likely to be observed in an adult beacuse in adults , lungs are fully developed and lack of surfactant is less.
Explanation:
Respiratory distress syndrome is a type of neonatal disease of respiration ,caused by deficiency of the surfactant produced by type II alveolar cells in the lungs most commonly in premature infants.
Normally , the lungs of the fetus start the formation of the surfactant during the third trimester (26 weeks through labor and delivery ) but in the premature infants , the lungs are not totally developed , hence lack of surfactant production results in the respiratory distress syndrome charactarized by inflammation of the airways due to the lack of the surface tension lowring effect of the surfactant.
I'm assuming you mean the molecular compound
and it's name is Hydronium. Hope this helps :)
<h2>Answer:</h2>
<u>The objects that allow humans to access ground water are:</u>
- <u>A spring</u>
- <u>a well drilled into an aquifer
</u>
- <u>a well drilled below the water table</u>
<h2>Explanation:</h2>
Access to ground water can be gained if we dig a well or use any source that can provide us an access below the water table. A water table is the level below which the ground is saturated with water. So above the saturation level we cannot gain access to water therefore we must go below it. A spring springs from ground below water table and the same thing occurs for well or an aquifer if it is below the water table..
The number of electrons in the outermost shell of an atom determines its reactivity.
