The graph shows the results of a famous biological experiment. in the experiment, kettlewell believed that the peppered moth demonstrated how environmental pressures influence evolution. he studied two areas. birmingham was a rural wood, with natural conditions. dorset was an urban, industrial area. the moths use tree trunks to camouflage themselves against birds, which are their major predators. natural gene variations produce a light form of the peppered moth, and a dark form, meaning that they are not equally visible.
all but one statement is supported by kettlewell's data. that is
question 1 options:
light moths had a survival advantage in forested birmingham.
dark moths had a survival disadvantage in forested birmingham.
dark moths had a survival disadvantage in industrial dorset.
light moths had a survival disadvantage in industrial dorset.

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.
