Agroup of 50 sparrows (small birds) were blown off course by a storm during their winter migration. the birds were stranded on an island in the middle of the pacific ocean. because this island was too far from the mainland for a yearly migration, the sparrows only mated with the other sparrows stranded on the island. after 500 years, this small isolated group of sparrows had beaks 25% longer than the mainland population. this is an example of:

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.
