You induce (using heat shock) the expression of mosaic patches in the eye disc that express a mutant BOSS protein that is missing five of its intramembrane alpha-helical domains. You collect the eye discs and immunolabel them with antibodies that recognize photoreceptor cells. Compare what you would see in the mutant mosaic patches with the […]
85 g sample containing only MgO and CyO is placed in a 3.00 L container. The container is filled with CO2 to a pressure of 740 torr at 20 degrees C.
A 2.85 g sample containing only MgO and CyO is placed in a 3.00 L container. The container is filled with CO2 to a pressure of 740 torr at 20 degrees C. After the reaction has gone to completion, the pressure inside the flask is 390 torr at 20 degrees C. What is the mass […]

A 69.0-kg person throws a 0.0450-kg snowball forward with a ground speed of 31.0 m/s. A second person, with a mass of 58.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.00 m/s, and the second person is initially at rest. What are […]
