Mixture vapour miller-urey experiment 1.water boiled reflect high - IB Biology HL

Text	Miller-Urey experiment: 1.Water was boiled to vapour to reflect the high temperatures common to Earth’s original conditions 2. The vapour was mixed with a variety of gases (including H2, CH4, NH3) to create a reducing atmosphere (no oxygen) 3. This mixture was then exposed to an electrical discharge (simulating the effects of lightning as an energy source for reactions) 4. The mixture was then allowed to cool (concentrating components) and left for a period of ~1 week 5. After this time, the condensed mixture was analysed and found to contain traces of simple organic molecules

Miller-Urey experiment:

1.Water was boiled to vapour to reflect the high temperatures common to Earth’s original conditions

2. The vapour was mixed with a variety of gases (including H2, CH4, NH3) to create a reducing atmosphere (no oxygen)

3. This mixture was then exposed to an electrical discharge (simulating the effects of lightning as an energy source for reactions)

4. The mixture was then allowed to cool (concentrating components) and left for a period of ~1 week

5. After this time, the condensed mixture was analysed and found to contain traces of simple organic molecules
