5. (3pts) 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).

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
