Ques:Answer the following question given this paragraph: The water cycle includes the ocean, atmosphere, ground, and living things. During the water cycle, water keeps changing state by processes such as evaporation, transpiration, condensation, and precipitation. Q: Precipitation, evaporation, transpiration, and condensation are part of what cycle? Choices: - life cycle - air cycle - cold cycle - water cycle A:

Ans:water cycle

Ques: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:

Ans:viscosity

Ques:Answer the following question given this paragraph: This is a "puffball" fungus. At maturity, clouds of a brown dust-like power escape when they are touched. This powdery substance is made up of spores, the reproductive structure of the fungus. Q: What is the cloud of brown dust-like power that escapes when a puffball fungus is touched? Choices: - ions - seeds - pollon - spores A:

Ans:
spores
