Answer the following question given this paragraph: Encephalitis and meningitis aren't very common, but they can be extremely serious. They may cause swelling of the brain, which can be fatal. That's why it's important to know the symptoms of these diseases. Both encephalitis and meningitis typically cause a severe headache and a fever. Meningitis also causes a stiff neck. Both require emergency medical treatment. Q: Fatal swelling of what organ can result from both encephalitis and meningitis, which typically cause a severe headache and a fever? Choices: - liver - heart - kidney - brain A:
brain

Answer the following question given this paragraph: A crystal contains a three-dimensional array of alternating positive and negative ions. The precise pattern depends on the compound. A crystal of sodium chloride, shown here, is a collection of alternating sodium and chlorine ions. Q: What does the precise pattern of a crystal depend on? Choices: - chance - mass - age - compound A:
(Answer)
compound

(Q).
Answer the following question given this paragraph: Figure 20.33 The outer surface of the heart changes from positive to negative during depolarization. This wave of depolarization is spreading from the top of the heart and is represented by a vector pointing in the direction of the wave. This vector is a voltage (potential difference) vector. Three electrodes, labeled RA, LA, and LL, are placed on the patient. Each pair (called leads I, II, and III) measures a component of the depolarization vector and is graphed in an ECG. Q: The outer surface of the heart changes from positive to negative during what? Choices: - inflammation - permeability - reproduction - depolarization A:
(A).
depolarization
Ques:Answer the following question given this paragraph: An electromagnet is a solenoid wrapped around a bar of iron or other ferromagnetic material. A solenoid is a coil of wire with electric current flowing through it. This gives the coil north and south magnetic poles and a magnetic field. The magnetic field of the solenoid magnetizes the iron bar by aligning its magnetic domains. You can see this in the Figure below . You can learn how to make an electromagnet at this URL: http://www. youtube. com/watch?v=emlzh9XXWgQ. Q: What is a coil of wire with electric current flowing through it called? Choices: - carrier valve - tectonic valve - hydraulic valve - a solenoid A:

Ans:a solenoid
Answer the following question given this paragraph: When an earthquake occurs under the ocean, it sends waves through the water as well as the ground. When the energy of the earthquake reaches shore, it forms a huge wave called a tsunami. Q: When the energy of the earthquake reaches shore, it forms a huge wave called? Choices: - a surge - a typhoon - a tidal wave - a tsunami A:
a tsunami
