Answer the following question given this paragraph: The cell is the smallest unit of structure and function of all living organisms. But this smallest of units still performs some very complex processes. In fact, for some organisms, just one cell must do everything necessary for life. Q: What is the smallest unit of structure and function of all living organisms? Choices: - atom - particle - proton - cell A:
cell

Answer the following question given this paragraph: Speed just takes distance and time into account. How might direction be considered as well?. Q: Speed takes distance and what else into account? Choices: - gravity - matter - energy - time A:
time

Answer the following question given this paragraph: This same logic explains the behavior of gyroscopes. Figure 10.31 shows the two forces acting on a spinning gyroscope. The torque produced is perpendicular to the angular momentum, thus the direction of the torque is changed, but not its magnitude. The gyroscope precesses around a vertical axis, since the torque is always horizontal and perpendicular to L . If the gyroscope is not spinning, it acquires angular momentum in the direction of the torque ( L falling over just as we would expect. Q: If a gyroscope is not spinning, it acquires angular momentum in the direction of what? Choices: - gravity - acceleration - velocity - torque A:
torque
