During early ages, the alkaline hot liquids from the vent met the acidic cold ocean water. the acidic ocean water produced a natural gradient across mineral wall in rocks that are rich in catalytic minerals. this difference in conditions converted and hydrogen into organic carbon-containing molecules. these can react with each other to form organic molecules, such as nucleotides and amino acids.

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.
