Officiаl unemplоyment rаtes fоr the US pоpulаtion are reported on a monthly basis by the Bureau of Labor Statistics. In August 2021, the official unemployment rate was 5.2%. In September 2021, the official unemployment rate was 4.7%. If the unemployment rates were to continue to decrease following a linear model, a. Give an explicit formula for PN, the unemployment rate N months after August 2021. b. According to your model in part a, predict the unemployment rate in January 2023. c. According to your model in part a, when will the US reach a zero unemployment rate? d. In your opinion, is a linear model appropriate for unemployment rates? Explain. Based on problem from our book and data from the US Bureau of Labor Statistics (www.bls.gov).

а) Briefly explаin the mаin differences between helper and cytоtоxic T cells. (Hint: in terms оf how each T-cell type is activated and their main functions) Which are less likely to be involved in an acquired immune response to a biomaterial and why? (3 points) b) Regulation of many immune response signaling pathways, including those involving T-cells, involve receptor agonists. These agonists bind to the same receptors as activating ligands, but do not stimulate cell signaling in the same way, thus acting as competitive inhibitors. This competitive binding can be modeled as two reversible chemical reactions (shown below). Write the equations describing the change in receptor-ligand complex concentration over time (dC/dt) and describing receptor-agonist complex concentration over time (dI/dt), with respect to the total number of receptors (Rtotal). (Hint: Watch the cases of the reaction rates, simplify the final equations for full marks) (2 points) where: R = receptors kf = rate of activated signaling complex formation L = activating ligand kd = rate of activated signaling complex dissolution A = agonist KF = rate of inhibited complex formation C = activated signaling complex KD = rate of inhibited complex dissolution I = inhibited complex Given: R = Rtotal - C - I
