In the most popular Miller-Urey experiment, the
most living organisms were first developed under the formation of the simple macromolecules
that composes most organelles in the cells of a living organism. It started
with the gases –methane, ammonia and hydrogen which came in contact with electric
spark that aided the first formation of the basic components like amino acids,
nucleic acids and RNA. Then resulted to the development of prokaryotes or the
autotrophs.
Answer:When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.
Explanation:
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.
