(I need help and I would greatly appreciate an in depth explanation on how to answer these, thank you in advance!!)

Atherosclerosis is a disease that results when certain cells and proteins of an individual’s body adhere to and damage blood vessels, especially those around the heart. Researchers continue to look for improved ways to treat individuals with the disease. Data obtained from earlier experiments suggested that it might be possible to reduce damage to the blood vessels by increasing the expression of FXR1, an RNA-binding protein in the muscle cells that form the outer surface of the blood vessels. Additional data suggested that IL-19, a protein secreted by certain white blood cells, might regulate expression of the FXR1 gene.

To investigate the regulation of the FXR1 gene by IL-19, a researcher added IL-19 to vessel-lining muscle cells growing in the lab. The researcher measured the amount of FXR1 protein produced by the cells over a period of 48 hours in the presence of IL-19. The researcher then calculated the relative amount of FXR1 present at each time point compared with the amount of FXR1 at Time 0, when IL-19 was first added to the cells. Data from three replicate experiments are shown in Table 1.
