(1pt total) You are working as a researcher at Metal-Ortho Implant, Inc. and are investigating a case of two patients who were received a metallic hip implant. After the implantation, the results of the blood test are shown below: Patient 1 – Elevated levels of hapten-carrier conjugates (metal ions from implant act as haptens) AND Elevated levels of TDTH (a class of Helper T Cells) Patient 2 – Elevated levels of C5 convertase Answer the following questions related to each patient.  (0.125pts) Patient 1: Briefly, define a hapten.  (0.125pts) Patient 1: Briefly, define a hapten-carrier conjugate and describe the immunological effect a hapten (metal ion)-carrier conjugate may elicit. (0.25pts) Patient 1: Identify what type of response this patient is most likely experiencing. Briefly, describe the response that occurs after the activation of TDTH –cells. MUST include at least one main immune cell recruited by the activated TDTH -cells.    (0.25pts) Patient 2: Which system is being upregulated? AND identify and briefly describe which sub-activation mechanism is most commonly associated with biomaterials.

Below circuit is the small signal equivalent of an amplifier. Among given choices, which one represents the formula for the RO , the output resistance of the amplifier?  Note: Parallel sign || has priority over addition +. As an example rpi + RB||Rs means RB || Rs is done first and then resulting value is added to rpi ro(1).jpg

  For the circuit shown below, assume collector current I C Q = 4   mA I_{CQ} = 4 \, \text{mA} , β = 100 \beta = 100 (with I E ≈ I C I_E \approx I_C ​), and V B E ( on ) = 0.7   V V_{BE(\text{on})} = 0.7 \, \text{V} . The emitter resistor R E R_E ​ is given as 1   k Ω 1 \, \text{k}\Omega , as indicated. Determine the value of R 1 R_1 that ensures the circuit remains bias-stable. For this calculation, you do not need the values of R C R_C or V C E V_{CE} ​. Assume the transistor operates in the forward active region. Select the value closest to your result. find R1.jpg
