Energy. A solute can only move against concentration gradients using active transport which requires energy

The connection between the beginning of life and the
universal genetic code is that they all started with a simple one celled
molecule. The Universal genetic code is a common language for almost all
organisms to translate nucleotide sequence of deoxyribonucleic acid that is DNA
and ribonucleic acid that is RNA to amino acid sequences of proteins. All
living Organisms have a genetic code generally represented by the sequence of
nucleotides in their DNA.
I believe the correct answer is natural selection.
Natural competition and the fight for “survival of the fittest” is what pushes diversity the most.
