Answer the following question given this paragraph: The tonsils are located on either side of the pharynx in the throat. They trap pathogens, which are destroyed by lymphocytes in the tonsils. Q: What are located on either side of the pharynx in the throat? Choices: - wrinkles - testicles - lymph nodes - tonsils A:
tonsils
Answer the following question given this paragraph: Energy conversion occurs when energy changes from one type or form of energy to another. Energy often changes between potential and kinetic energy. Energy is always conserved during energy conversions. Q: Energy often changes between potential and what other kind of energy? Choices: - magnetic - thermal - realized - kinetic A:
kinetic
Q: Answer the following question given this paragraph: Graphite is one of three forms of crystalline, or crystal-forming, carbon. Carbon also exists in an amorphous, or "shapeless," form in substances such as coal and charcoal. Different forms of the same element are called allotropes. Besides graphite, the other allotropes of crystalline carbon are diamond and fullerenes. All three forms exist as crystals rather than molecules. In a crystal, many atoms are bonded together in a repeating pattern that may contains thousands of atoms. The arrangement of atoms in the crystal differs for each form of carbon and explains why the different forms have different properties. For an entertaining, video-game introduction to the three forms of crystalline carbon, go to this URL: http://www. youtube. com/watch?v=GIHmfBsHsCY . Q: Different forms of the same element are called what? Choices: - subclasses - amines - polymorphs - allotropes A:
A: allotropes
Question: Answer the following question given this paragraph: These devices are not very sensitive to low levels of radiation, but more sensitive devices are also available that reliably measure the frequency of radioactive events. One such device is the Geiger counter. A Geiger counter is a tube filled with an inert gas that will conduct electricity when exposed to charged radiation, such as alpha or beta particles. When a charged particle enters the tube, it changes the electrical potential between the anode and the cathode, and this change in potential is registered by an electrical circuit as a single radioactive event. Geiger counters are fairly inexpensive and reliable, so they are useful in a wide range of applications. More complicated types of counters are also available, but are generally used only in sophisticated experiments. Q: What is the tube-like device used to reliably measure lower levels of radiation? Choices: - Richter scale - weber counter - MRI machine - geiger counter A:
Answer: geiger counter

Answer the following question given this paragraph: The blue lines in this drawing represent nerves of the peripheral nervous system. Every peripheral nerve is connected directly or indirectly to the spinal cord. Notice the thick sciatic nerve. It is the longest (and thickest) nerve in the body, running from the lower region of the spinal cord to just above the knee. Q: Every peripheral nerve is connected directly or indirectly to what? Choices: - the functional cord - the umbilical chord - the optimal cord - the spinal cord A:
**Answer**
the spinal cord
(Q).
Answer the following question given this paragraph: Matter is anything that has mass and takes up space. Matter is everywhere. The air we breathe, the water we drink, the food we eat, and the ground we walk on are all comprised of matter. Matter can take on a variety of different forms which all have a variety of different properties. In this chapter, we will introduce the characteristics of matter and study how these characteristics vary in different types of matter. Q: Anything that has mass and takes up space is considered what? Choices: - energy - light - power - matter A:
(A).
matter
