Answer:
The 5' cap is added to the mRNA as a means of protection from being degraded by enzymes in the cellular environment. Additionally. it helps with binding to the ribosome and subsequently translating it into a protein.
Explanation:
Moreover, it's only Polymerase II that has the ability to add the 5' cap and rRNA & tRNA are not transcribed by Polymerase II, only the mRNA is.
rRNA and tRNA have stable 3-Dimensional structures that protects it from being degraded by enzymes.
Hope that answers the question, have a great day!

A sole carbon particle: The degradation of particulate organic matter in the ocean is a central process in the global carbon cycle, the mode and tempo of which is determined by the bacterial communities that assemble on particle surfaces.
Answer: The correct answer for the fill in the blank is B) Advantageous traits become more common in a population.
Theory of natural selection was given by Darwin. This is one of the mechanisms of evolution.
According to this theory, organisms that are better adapted to their environmental conditions survive and increase their population by reproduction. So they pass the advantageous trait to the next generation. In other words, it reflects the survival of the fittest.
Due to this, the advantageous trait becomes more common in the population.
Thus, the correct option is B)
