Questions
Reаd the lаb descriptiоn аnd answer questiоns 1-7 Jill was tasked with determining which brand оf pen is most likely to attract a termite. She selected 5 brands of black ink pen, Bic, Precision V5, Sharpie, Papermate, Pilot, plus a pencil. Jill knows from previous experience that the termites are attracted to ink from a black Bic pen and are not attracted to lead from a pencil. To complete the experiment Jill drew a 5 cm diameter circle with each pen and placed a termite 0.5 cm from each circle. She then gave the termite 30 seconds to find the circle and travel around the circle. Jill defined positive results as a termite finding the circle within 30 seconds and then following the circle at least half way around. A negative result would be a termite that was unable to find the circle within 30 seconds or a termite that found the circle but followed it for less than half the circle. Jill tested five termites on each brand of pen for a total of thirty termites. The results of Jill’s experiment are found in the table below. Table 1: Number of termites that found the black 5 cm diameter circle within 30 seconds and then followed the circle for at least half the total distance. Brand of pen Bic Precision V5 Sharpie Papermate Pilot Pencil # of termites 5 1 0 2 5 1 What is Jill's sample size?

Exаct Sciences, а biоtech cоmpаny lоcated here in Madison, screens for colon cancer by testing the DNA found in patients’ fecal samples. One of the things they look for is mutations in a gene called KRAS, which codes for a protein that controls cell growth. Mutations in this gene can cause cancer by triggering uncontrolled cell growth. Colon cancer screening is traditionally done using a camera to inspect the colon visually and test tissue samples at the biological scale of tissues. In contrast, Exact Sciences’ approach focuses on the biological scale of molecules, looking for DNA mutations. In 3-4 sentences, explain how the molecular-scale mutations in the KRAS gene lead to tissue-scale cancer development, using the concepts of IFES and SF. Your answer should describe the full pathway from DNA mutation to the outcome at the tissue level, and include the core concepts of both IFES and SF.
