Mutations in region B and region D give the same results - when either of these regions is mutated, the operon is expressed under all conditions (called constitutive expression). You hypothesize that region B is the operator region and that Region D is the repressor protein. To test your hypothesis, you create two partial diploid lines by introducing a F' plasmid with a wild-type lac operon: Strain 1: F' A B C D E / A B- C D E Strain 2: F' A B C D E / A B C D- E What experimental results would be predicted by your hypothesis

Ascientist is investigating the effects of salinity on fish development. he places fertilized fish eggs in an aquarium that contains low salinity and observes their development. what factor would improve experimental design the most? place the fish eggs in the open ocean because that is the natural habitat include another aquarium that has normal salinity to compare to the low salinity aquarium include an aquarium that replaces salt with sugar to confirm that the effects are specific to salt grow algae with the fish eggs in order to provide adequate nutrients to the developing embryos
