Q: Answer the following question given this paragraph: Bioterrorism is the intentional release or spread of agents of disease. The agents may be viruses, bacteria, or toxins produced by bacteria. The agents may spread through the air, food, or water; or they may come into direct contact with the skin. Two of the best known bioterrorism incidents in the U. S. occurred early in this century:. Q: The intentional release or spread of agents of disease is known as what? A:

OPTIONS:
- act of war
- pandemic
- disaster
- bioterrorism

A: bioterrorism

input: OPTIONS:
- the shell
- the nucleus
- the ellipse
- the orbital Now, answer this question: Answer the following question given this paragraph: Negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving around the nucleus. The region where an electron is most likely to be found is called an orbital. Q: What is the region called where an electron is most likely to be found? A:
A:
output: the orbital

Answer the following question given this paragraph: Because they cannot escape the container, the vapor molecules above the surface of the liquid exert a pressure on the walls of the container. The vapor pressure is a measure of the presure (force per unit area) exerted by a gas above a liquid in a sealed container. Vapor pressure is a property of a liquid based on the strength of its intermolecular forces. A liquid with weak intermolecular forces evaporates more easily and has a high vapor pressure. A liquid with stronger intermolecular forces does not evaporate easily and thus has a lower vapor pressure. For example, diethyl ether is a nonpolar liquid with weak dispersion forces. Its vapor pressure at 20C is 58.96 kPa. Water is a polar liquid whose molecules are attracted to one another by relatively strong hydrogen bonding. The vapor pressure of water at 20C is only 2.33 kPa, far less than that of diethyl ether. Q: What term describes a property of a liquid based on the strength of its intermolecular forces? A:

OPTIONS:
- analogous pressure
- cellular pressure
- tissue pressure
- vapor pressure

Answer: vapor pressure

Problem: OPTIONS:
- color
- temperature
- density
- speed
Q: Answer the following question given this paragraph: When light passes from one medium to another, it changes speed. For example, when light passes from air to glass, it slows down. If light strikes a sheet of glass at a 90 angle, or perpendicular to the glass, it slows down but still passes straight through the glass. However, if light enters the glass at an angle other than 90, the light bends as it slows down. The bending of light as it changes speed in a new medium is called refraction . The Figure below shows how refraction occurs. Notice that the speed of light changes again as it passes from the glass back to the air. In this case, the speed increases, and the ray of light resumes its initial direction. For a more detailed explanation of refraction, watch this video: http://www. youtube. com/watch?v=8RM46yvDOHI . Q: When light passes from one medium to another, it changes what? A:
Answer: speed
