In 1953 S.L. Miller created primitive earth conditions in the labortory and gave experimental evidence for origin of first form of life from pre-existing non-living. Organic molecuels. The primitve earth condition created include.

Options

A. low temperature, volcanic storms, atmosphere rich in oxygen
B. low temperature, volcanic storms, reducing atmosphere
C. high temeprature, volcanic storms, non-reducing atmosphere
D. high temperature, volcanic storms, reducing atmosphere containing `CH_(4),NH_(3)` etc.

Answer

D

Explanation

(d) The miller- Urey experiment tested for the occurrence of chemical evolution by stimulating hypothetical conditions present on early earth.
These primitive earth condition include high temperature , volcanic storms and reducing environment containing methane `(CH)_(4)`, ammonia `(NH_(3))`, hydrogen `(H_(2))` and water `(H_(2)O)`.
They ultimatlely found that a large number of simple organic compounds including some amino acids such as alanine, glycine and aspartic acid can be synthesised in into as during chemical origin of life.
