Human blood glucose (the amount of glucose in the blood) is sensed by chemoreceptors on the pancreas. When blood glucose is too low , the pancreas secretes the hormone glucagon. When glucagon binds to liver cells, it causes them to break glycogen down into glucose and release that glucose into the blood stream. What will happen when the chemoreceptors on the pancreas sense that blood glucose levels are almost back up to normal (set point) again?

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 have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. b. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. c. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails.
