Answer the following question given this paragraph: Velocity is defined as change in position over time. Can you see that would be the slope of this graph? (slope = rise over run and in this case the 'rise' is position and the 'run' is time). Find the instantaneous speed at sec. Q: What term refers to change in position over time? A:

OPTIONS:
- Position Replacement
- acceleration
- Direction Replacement
- velocity

Answer: velocity

Problem: OPTIONS:
- UP ticked.
- refreshed
- plugged
- recharged
Q: Answer the following question given this paragraph: Primary Batteries Primary batteries are single-use batteries because they cannot be recharged. A common primary battery is the dry cell (Figure 17.10). The dry cell is a zinc-carbon battery. The zinc can serves as both a container and the negative electrode. The positive electrode is a rod made of carbon that is surrounded by a paste of manganese(IV) oxide, zinc chloride, ammonium chloride, carbon powder, and a small amount of water. The reaction at the anode can be represented as the ordinary oxidation of zinc: Zn(s) Zn 2+(aq) + 2e . Q: Primary batteries are single-use batteries because they cannot be what? A:
Answer: recharged

Problem:OPTIONS:
- elasticity
- volume
- salinity
- viscosity

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? A:
****
A: viscosity

Answer the following question given this paragraph: Cells that are communicating may be right next to each other or far apart. In juxtacrine signaling , also known as contact-dependent signaling, two adjacent cells must make physical contact in order to communicate. Cell communication may also occur over short distances, which is known as paracrine signaling , or over large distances, which is known as endocrine signaling . Q: Cell communication that occurs over short distances is known as what? A:
OPTIONS:
- hypersignaling
- contraposition signaling
- cell echo
- paracrine signaling
paracrine signaling

Answer the following question given this paragraph: Water pollution comes from many sources. One of the biggest sources is runoff. Runoff picks up chemicals such as fertilizer from agricultural fields, lawns, and golf courses. It carries the chemicals to bodies of water. The added nutrients from fertilizer often cause excessive growth of algae, creating algal blooms (see Figure below ). The algae use up oxygen in the water so that other aquatic organisms cannot survive. This has occurred over large areas of the ocean, creating dead zones , where low oxygen levels have killed all ocean life. A very large dead zone exists in the Gulf of Mexico. Measures that can help prevent these problems include cutting down on fertilizer use. Preserving wetlands also helps because wetlands filter runoff. Q: What source of water pollution picks up chemicals from the ground with water and carries them to bodies of water? A:
OPTIONS:
- fertilizer
- erosion
- sediment
- runoff

Answer:
runoff
