What hypothesis did miller-urey test in their experiment?
a. organic molecules can form in a reducing atmosphere.
b. earth is a primordial soup.
c. organic molecules cannot survive in a reducing atmosphere.

The answer s the option B. Earth is a primordial soup. They tested Oparin's theory which states that the life (organic matter) can be formed from inorganic compounds. They placed a mixture of compounds that are supposed to be present in Earth before life started, which are CO2, methane (CH4) and water (H2O), hydrogen (H2) and nitrogen (N2) in a closed vessel and used electric discharges (to simulate the effects of the storms that happened in Earth without atmosphere). Then they analyzed the products obtained and indeed found organic matter. Yet, this does not mean that life is definetly originated in this form.

Anions are negative charged ions
