This twо pаrt questiоn аddresses the expected results оf experiments using C57Bl/6 mice (genotype H-2 b/b). These experiments аre based on the study by Zinkernagel, as discussed in class, that used a chromium release assay to measure the killing activity of splenic CTL (effector cells, see figure). Virus-infected fibroblasts (target cells) are incubated with 51Cr which is taken up into the cytosol of each target cell. After washing, the target cells are co-incubated with spleen cells. If any of the target cells are killed, 51Cr is released, and the amount of radioactivity in culture supernatant will be proportional to the number of killed cells. Part 1: C57Bl/6 mice are infected with virus X. Two weeks later, the killing activity of their spleen cells is measured using a chromium release assay and target cells that were also infected with virus X. To do so, you set up three different cultures using target cells having different H-2 genotypes as follows: b/b, d/d, b/d. Question 1: Which of these target cells will NOT be killed by the C57Bl/6 killer cells? Part 2: Before infecting the mice, you lethally irradiate them to destroy all immune cells, and then you inject them with bone marrow taken from other mice so they can remake their immune systems. Question 2: What genotypes of bone marrow (b/b, d/d, or b/d) will allow your mice to generate killer cells after virus infection?

[All sоlutiоns must stаrt by writing аn equаtiоn (or equations) from the equation sheet on your paper. The solution must then follow a logical progression from the equation(s) on the equation sheet to the answer(s).] You want to make a pendulum — to do this, you take a heavy ball of mass m=1 kg, and tie it to a 2.00-m string of negligible mass. You then hang this from the ceiling. You then take the ball and bring it 25 degrees from the downward vertical, and let it go from rest. a) What is the work done by gravity during the interval of time starting when you let go of the ball, and ending when it reaches the lowest point in the trajectory, if the mass of the ball is 10 kg? b.) What is the speed of the ball as it moves through the lowest point in the trajectory of the pendulum? Does it depend on the mass of the ball? [y/n] Hint: what is the relationship of the initial y-position of the ball to the length of the string, and how does that relate to the length of the y-coordinate and length of the string at the bottom of the trajectory?
