BIOS1610 - Chapter 10 HDWK Questions and Answers | Latest Update | 100% Pass **Why does the Background section mention Bissell's research on mammary cells?** **It provides context from a related experiment that influenced Caron's own question and hypothesis.** **What hypothesis did Caron propose for her experiment?** **Caron hypothesized that a protein present in the extracellular matrix is necessary for hepatocytes to secrete albumin.** **What is the null hypothesis for Caron's experiment?** **The null hypothesis is that a protein present in the extracellular matrix is not necessary for hepatocytes to secrete albumin.** **In Caron's experiment, what role did plating cells on a thin layer of type I collagen alone serve?** **It served as the negative control.** **The Follow‐up Work section discusses additional research by Bissell in this field.** **Which statement accurately describes the Follow‐up Work section?** **Bissell utilized the findings from Caron's experiment to explore further questions regarding mammary cells.** **Caron measured both mRNA and protein levels (top two graphs). What do the results shown in these graphs indicate about mRNA and protein levels?** **They show a positive correlation between mRNA and protein levels.** **In the bottom graph, what do the purple bars and green bars signify when compared?** **They indicate the relative amount of mRNA expression at two different time points.** **To determine whether laminin increases mRNA expression in the bottom graph, what comparison would you need to make?** **You would need to compare the green bar in the laminin-only group to the green bar in the group with no matrix proteins.** **If Caron had conducted the first set of experiments (top two graphs) but not the second set (bottom graph), which interpretation would be consistent with her findings?** **All options could potentially explain the data from the first set of experiments.** **Suppose Caron found that mRNA levels increased in response to laminin, but protein levels did not. What conclusion could she draw
