Which statement best supports the RNA world hypothesis? DNA molecules are a precursor to self-replicating RNA molecules, which are used to build proteins.
Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code.
Simpler self-replicating organic molecules preceded RNA and contain genetic information.
The absence of oxygen in Earth's early atmosphere allowed for proteins to catalyze the production of new RNA molecules.

where is the scientific experiment?

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
