<span>It is believed that in the evolutionary history of life on Earth, there was the RNA world before DNA and proteins.</span> <span>RNA is a self-replicating molecule that can store and replicate genetic information and catalyze (ribozymes-RNA enzymes) reactions that are important for life. Because of these characteristics, it is possible that RNA world really existed. Because of the better stability and durability than RNA DNA later it became the predominant storage molecule.</span>
Answer:Absolute Threshold
Explanation:
The sensitivity of any given sensory system to the relevant stimuli can be expressed as an absolute threshold
