The function of phy B gene in leaf growth in Arabidopsis and the relation of this function to phy C and phy A. Given: It has been given in the results that mutation of phy B gene leads to elongation of leaf and reduction in the leaf area in relation to the wild-type plant. Introduction: Arabidopsis plant has a number of different phytochrome genes like phyC, phyA, phyB, and phyD, which together determine various important developments in the plants. The developmental pathway influences the determination of leaf area and length of the leaf. These genes may have overlapping, synergistic, or redundant roles in these development processes.

Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables. Do not solve the equations.

Case Study—Ella Review the case study and then answer Parts A through F. Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.
