Chromatography columns have a limited protein binding capacity. During lab #4 you should not have "overloaded" the Ni+2 Agarose column. Yet you may have noticed that the W2 fraction fluoresced slightly. If you see a band in the Western blot W2 lane, what does this data say about the physical protein structure of rGFP in that lane? Give a possible MW for this band based upon the data (show your work).

Ascientist separates a population of mice into two groups. what would most likely increase the rate of speciation in this population. a. teach the two groups different tricks b. allow the two groups to breed with each other c. put the two groups in different environment d. have the two groups live in identical ecosystems

As molecules are formed from metabolism, entropy __ and the universe becomes less disordered. a. is decreased b. is increased c. moves closer to equilibrium d. is unchanged

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
