Scientists have engineered bacteria to produce human proteins such as factor viii, a blood clotting factor to treat hemophilia. suppose the unmodified eukaryotic gene coding for factor viii is inserted directly into a bacterial chromosome. select the reasons why no expression would be seen in the bacterial cell for the factor viii gene.

Astudent sees several ants walking up a wall following the exact same trail that an ant took earlier. she wants to apply the scientific method to determine how the ants detected the trail. which of these steps would come first in her application of the scientific method? perform an experiment by cleaning the scent away from part of the trail. draw a conclusion that the ants follow a scent trail. make a prediction about what the ants will do after she cleans away part of the trail. hypothesize that the ants are following a scent trail that the first ant left.
