Weathering, plate movements, and volcanoes destroyed many of the craters. The factors contribute to the lack of evidence of heavy bombardment of earth. This evidence was subjected or, if not subjected, weathered; since Earth was and still is a "living" planet, meaning a planet with active plate tectonics and an active hydro/atmosphere. This activity is in contrast to the Moon, where plate tectonics stopped shortly after its formation and where a hydro-atmosphere could never form. Both because the Moon was simply too small to sustain plate tectonics and to keep volatility with him/her.
Prokaryotic cells: lack membrane-bound organelles, relatively small - typically less than 10 μm in size.
Both cell types: use ribosomes to synthesize proteins, contain DNA.
Eukaryotic cells: complete copy of DNA stored in multiple chromosomes.
In particular, prokaryotic cells have no nucleus and no membrane-bound organelles, therefore their ribosomes float freely intracellularly. On the other hand, eukaryotic cells have nucleus and membrane-bound organelles. Also, their DNA is bound to proteins and stored in the form of chromosomes in the nucleus.

Answer:
Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple. Litmus can also be prepared as an aqueous solution that functions similarly.
