notka56 [123]

Answer;

Arrangement of events in stellar formation;

C) The Big Bang occurs.

B) Pockets of elements in higher concentrations begin experiencing greater gravitational force.

A) Hydrogen atoms shed their electrons and fuse together to form larger helium atoms.

D) the glass clouds begin reducing in volume, which leads to increase in density, pressure, and temperature.

Explanation;

-Stellar evolution is the process by which a star changes over the course of time. All stars are born from collapsing clouds of gas and dust, often called nebulae or molecular clouds.

-Stars are born out of the gravitational collapse of cool, dense molecular clouds. As the cloud collapses, it fragments into smaller regions, which themselves contract to form stellar cores.

How did the discovery of ribozymes assist in creating a plausible model for the prebiotic origin of life?
aleksley [76]
Ribozymes are biochemically too complex to have ever produced themselves naturalistically. They are an intermediate cellular functioning assembly that cannot survive on its own and they are too restrictive in function to enable metabolism and reproduction at the level of criticality to be considered plausible for life.

Their simplicity relative to RNA and DNA make them an attractive possibility, but they are not strategic enough, robust enough or in any producible using naturalistic processes.
