100 POINTS! Question 2 Sammi decides to design a model to show how the digestive and circulatory systems interact. She lines a large plastic tube with a corrugated cardboard tube. Then, she connects smaller plastic tubes to the large plastic tube. These small tubes connect to a pump. She drills small holes in the large tube so that all of the plastic tubes connect.

She plans to run a green fluid representing food through the cardboard tube.

Question
Match each part of Sammi's model to the bodily structure it represents. One bodily structure has already been labeled for you.

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.
