Answer the following question given this paragraph: The force exerted by circulating blood on the walls of blood vessels is called blood pressure . Blood pressure is highest in arteries and lowest in veins. When you have your blood pressure checked, it is the blood pressure in arteries that is measured. High blood pressure, or hypertension , is a serious health risk but can often be controlled with lifestyle changes or medication. You can learn more about hypertension by watching the animation at this link: http://www. healthcentral. com/high-blood-pressure/introduction-47-115. html . Q: What is the term for the force exerted by circulating blood on the walls of blood vessels? Choices: - circulation pressure - heart pressure - blood energy - blood pressure A:
blood pressure
Answer the following question given this paragraph: Air temperature changes as altitude increases. In some layers of the atmosphere, the temperature decreases. In other layers, it increases. You can see this in Figure below . Refer to this figure as you read about the layers below. Q: Air temperature changes as what increases? Choices: - pressure - density - salinity - altitude A:
altitude
Q: Answer the following question given this paragraph: Discussion for (a) This value is the net work done on the package. The person actually does more work than this, because friction opposes the motion. Friction does negative work and removes some of the energy the person expends and converts it to thermal energy. The net work equals the sum of the work done by each individual force. Strategy and Concept for (b) The forces acting on the package are gravity, the normal force, the force of friction, and the applied force. The normal force and force of gravity are each perpendicular to the displacement, and therefore do no work. Solution for (b) The applied force does work. Q: Friction does negative work and removes some of the energy the person expends and converts it to which kind of energy? Choices: - erosion - hydro - evaporation - thermal A:
A: thermal
Question: Answer the following question given this paragraph: The lithosphere is made of the rigid, brittle, solid crust and uppermost mantle. Q: Which part of the earth is made of the rigid, brittle, solid crust and uppermost mantle? Choices: - troposphere - thermosphere - atmosphere - lithosphere A:
Answer: lithosphere

Answer the following question given this paragraph: Vesicles are much smaller than vacuoles and have a variety of functions. Some vesicles pinch off from the membranes of the endoplasmic reticulum and Golgi apparatus. These vesicles store and transport proteins and lipids. Other vesicles are used as chambers for biochemical reactions. Q: Are vesicles larger or smaller than vacuoles? Choices: - larger - narrower - wider - smaller A:
**Answer**
smaller
