NATS 1840 Lecture Notes - Hydrogen Sulfide, Hydrochloric Acid, Nitrogenous Base
Document Summary
Science, technology and the environment (sc nats 1840a) . Planets formed from same cloud of gas and dust as the sun, about 4. 6 billion years ago . Being made of the same stuff , terrestrial planets were very similar to one another at first. Current condition on mars and venus suggest what primordial. Earth"s original atmosphere probably looked much like those of venus and mars today. Gasses likely to have been present include: carbon dioxide (co2), nitrogen (n2), water (h2o), Methane, ammonia, hydrogen sulfide, hydrochloric acid, molecular hydrogen. Accepted scientific view of our origins begins with conditions on the newly-formed planet earth. High ultra-violet (uv) radiation from the sun. All known life forms are built up from organic molecules. Such macromolecules involve thousands of atoms and come in four main types. All are polymers made up of chains of simpler molecules called monomers. Composed of one more chains of amino acids.
