In a certain state, electricity is generated by using Earth's heat. Wells are drilled and natural steam is taken out through pipes. This natural steam powers the generator and electricity is generated. Which type of renewable energy resource is being used and which type of power plants are set up for harnessing this renewable resource?

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
