What is the most important factor in successful learning

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.

How did global wind belts and calm regions affect transportation in the past? !

Tuberculosis is a disease caused by a bacterium and can often be fatal. for several decade , antibioticre very succesful in killing tuberculosis bacteria but now strains of the bacteria have developed that can only killed by when treated for long period of time with multiple types of antibiotics. why have the antibiotics become less effective aagainst tuberculosis
