Marcus is studying plant growth. He uses four identical trays of potting soil. He plants 2 marigolds in the first tray, 5 in the second tray, 8 in the third tray, and 15 in the last tray.
Marcus places each of the trays on the same table near a window. Each day he adds an
equal amount of water to the soil in each tray. Once a week for the next month, Marcus
measures the heights of the plants in each tray.

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.
