1.Speculate about how reasonable you think these theories are. Are the events that formed planets, biological molecules, and cells probable or improbable? Explain why you believe as you do

2."Living things reproduce" and "Living things inherit traits through their genes" are two characteristics of life. Apply your knowledge of cells and heredity as you think of what other molecules and biological processes would need to be present in order for a protobiont to be considered a living entity.
