Q: Answer the following question given this paragraph: Pillow lava is created from lava that enters the water. The volcanic vent may be underwater. The lava may flow over land and enter the water ( Figure below ). Once in the water, the lava cools very quickly. The lava forms round rocks that resemble pillows. Pillow lava is particularly common along mid-ocean ridges. Q: Lava that enters the water is called what? Choices: - lava flow - magma runoff - saltwater lava - pillow lava A:
A: pillow lava
Question: Answer the following question given this paragraph: The cell cycle is a repeating series of events, characterizing the life of a eukaryotic cell. Q: What does the cell cycle do? Choices: - only divide cells - create new cells - only reproduce cells - divide and reproduce cells A:
Answer: divide and reproduce cells

Answer the following question given this paragraph: 12.4 Viscosity and Laminar Flow; Poiseuille's Law Laminar Flow and Viscosity When you pour yourself a glass of juice, the liquid flows freely and quickly. But when you pour syrup on your pancakes, that liquid flows slowly and sticks to the pitcher. The difference is fluid friction, both within the fluid itself and between the fluid and its surroundings. We call this property of fluids viscosity. Juice has low viscosity, whereas syrup has high viscosity. In the previous sections we have considered ideal fluids with little or no viscosity. In this section, we will investigate what factors, including viscosity, affect the rate of fluid flow. The precise definition of viscosity is based on laminar, or nonturbulent, flow. Before we can define viscosity, then, we need to define laminar flow and turbulent flow. Figure 12.10 shows both types of flow. Laminar flow is characterized by the smooth flow of the fluid in layers that do not mix. Turbulent flow, or turbulence, is characterized by eddies and swirls that mix layers of fluid together. Q: What term refers to the friction of fluid, within itself and its surroundings? Choices: - elasticity - volume - salinity - viscosity A:
**Answer**
viscosity
