Answer:
This implies that DNA and proteins evolved after RNA.
Explanation:
It is believed that RNA predated today's cells in evolutionary history. RNA existed as the genetic material of the primitive cells of the time that were mainly constituted of globules of fat oil suspended in water in the oceans and lakes. Even in cells today, RNA molecules themselves can act as catalysts such as in the case of peptidyl transferase reaction that takes place on the ribosome.
Renewable resources are is a natural resource that can be made/provided again. Ex: solar energy, water, and biomass. Hope this works not really good with BIO.

1. weathering reduces solid rocks to smaller and smaller particles and erosion is the removal and movement of rocks/debris. so u could say that weathering breaks rocks down and erosion takes it away
2. water, wind, gravity
3. vegetation reinforces soil through growing over the loose soil to prevent erosion
1. - loss of fertile land and increased sedimentation in rivers
2. deforestation, agriculture, human induced climate change
