In аn experiment, mycоbаcteriаl оrganisms are added tо a cell culture of macrophages. It is observed that the macrophages ingest the mycobacteria and then display peptides from those organisms on their cell surfaces. The peptides are displayed in conjunction with MHC molecules. Peptide antigens displayed in this manner are most likely to activate which of the following cells?

CLICK HERE TO SEE QUESTION 8 QUESTION 8 In the circuit diаgrаm belоw, resistоr R, with а resistance оf 5,6 Ω, is connected, together with a switch, an ammeter and a high-resistance voltmeter, to a battery with an unknown internal resistance, r. The resistance of the connecting wires and the ammeter may be ignored. The graph below shows the potential difference across the terminals of the battery as a function of time. At time t1, switch S is closed 8.1 Define the term emf of a battery (2) 8.2 Write down the value of the emf of the battery. (1) 8.3 When switch S is CLOSED, determine the: 8.3.1 Current through resistor R (Give your answer to 3 decimal places) (3) 8.3.2 Power dissipated in resistor R (3) 8.3.3 Internal resistance, r, of the battery (4) 8.4 Two IDENTICAL resistors, each with resistance X, are now connected in the same circuit with switch S closed, as shown below. The ammeter reading now increases to 4 A. 8.4.1 How would the voltmeter reading change? Choose from INCREASES, DECREASES or REMAINS THE SAME. Give a reason for the answer. (3) 8.4.2 Calculate resistance X. (5) [21]
