2. BIO 240 Crime Scene Forensics Worksheet For more course tutorials visit www.uophelp.com Introduction: In recent years, law enforcement has been revolutionized by molecular biology. When human tissues are left behind at crime scenes, these tissues can be collected and processed to yield samples of DNA, which can then be treated to isolate specific DNA fragments that are highly variable in the human population. Which band pattern among Lanes 3 to 6 seems to be the closest match to the band pattern in Lane 2, where the crime-scene DNA fragment was loaded? Which suspect appears to be the culprit?

3. BIO 240 Disruption of a Marine Food Web Worksheet For more course tutorials visit www.uophelp.com Examine the graphs in the Lab Book, and describe any trends you observe among kelp, purple sea urchin, and sea otter populations. What happened to all three populations when catastrophe struck the sea otters? Which populations were wiped out, and in what order? Why do you think the removal of the otters caused the other two populations to crash as well? Examine the graphs in the Lab Book.

11. BIO 240 Week 2 DQ 1 For more course tutorials visit www.uophelp.com There is a fierce competition among individuals within any species, humans included, to gain access to reproductive privileges. The “fittest” – a term that signifies the largest, prettiest, and most sexually attractive members, succeed in predominantly mating and having offspring, while the less attractive ones often do not. What is the role of such sexual selection from an evolutionary standpoint?

17. BIO 240 Week 4 DQ 1 For more course tutorials visit www.uophelp.com Consider the human eye, an exquisitely adapted organ that gives rise to stereo vision in full color (see, for instance, “The Evolution of Primate Color Vision” by Gerald H. Jacobs and Jeremy Nathans, Scientific American, April 2009 issue, pp. 56-63).Explain, strictly from within the framework of Darwinian evolution, how natural selection “crafted” such an organ.
