8.which of the following kinds of molecules is thought to have been absent from the primitive reducing atmosphere?

In evolutionary biology, abiogenesis, or informally the origin of life (OoL), is the natural process by which life has arisen from non-living matter, such as simple organic compounds. While the details of this process are still unknown, the prevailing scientific hypothesis is that the transition from non-living to living entities was not a single event, but an evolutionary process of …

9.which of the following kinds of molecules is thought to have been absent from the primitive reducing atmosphere?

The early atmosphere of the Earth was a reducing atmosphere, meaning there was little to no oxygen. The gases that mostly made up the atmosphere were thought to include methane, hydrogen, water vapor, and ammonia. The mixture of these gases included many important elements, like carbon and nitrogen, that could be rearranged to make amino acids.

10.which of the following kinds of molecules is thought to have been absent from the primitive reducing atmosphere?

Conditions on the primitive Earth are thought to have favored the spontaneous formation of organic monomers, the linking of these monomers into polymers, the development of self-replicating molecules, and the grouping of aggregates of organic molecules into primitive cell-like structures that eventually emerged as primitive cells

1  Miller Experiment / Miller–Urey experiment- origin of life NCERT CLASS 12
The Miller–Urey experiment (or Miller experiment) was a chemical experiment that simulated the conditions thought at the time to be present on the early Earth, and tested the chemical origin of life under those conditions. The Miller-Urey experiment was immediately recognised as an important breakthrough in the study of the origin of life. It …
