The opossum, which is native to North America, and the kangaroo, which 5 points
is native to Australia, are marsupials. The fact that both these mammals
incubate their immature offspring in a pouch provides evidence that they

O belong to the same species.
O must range great distances to eat.
O have very similar skeletal structures.
O are descended from a common ancestor.

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.
