Answer the following question given this paragraph: Always properly dispose of hazardous waste. For example, let liquid waste evaporate before placing the container in the trash. Q: What should you let liquid waste do before placing the container in the trash? Choices: - expand - generate - melt - evaporate A:
evaporate
Answer the following question given this paragraph: An enzyme is an organic catalyst produced by a living cell. Enzymes are such powerful catalysts that the reactions they promote occur rapidly at body temperature. Without the help of enzymes, these reactions would require high temperatures and long reaction times. The molecule or molecules on which an enzyme acts are called its substrates. An enzyme has an active site where its substrate or substrates bind to form an enzymesubstrate complex. The reaction occurs, and product is released:. Q: An enzyme is an organic catalyst produced by what? Choices: - DNA - the liver - amino acid - living cell A:
living cell
Q: Answer the following question given this paragraph: Viewed from Earth, Mars is red. This is due to large amounts of iron in the soil. The ancient Greeks and Romans named the planet Mars after the god of war because the planet's red color reminded them of blood. Mars has only a very thin atmosphere made up mostly of carbon dioxide. Q: Mars appears red because of large amounts of which element in the soil? Choices: - carbon - coal - mercury - iron A:
A: iron

Q: The muscles in arteries and veins that are largely responsible for regulation of blood pressure are known as what type? Choices: - opposing muscles - vascular muscles - elongated muscles - smooth muscles A:
Answer: smooth muscles

Answer the following question given this paragraph: Gray Horns In cross-section, the gray matter of the spinal cord has the appearance of an ink-blot test, with the spread of the gray matter on one side replicated on the othera shape reminiscent of a bulbous capital "H. " As shown in Figure 13.14, the gray matter is subdivided into regions that are referred to as horns. The posterior horn is responsible for sensory processing. The anterior horn sends out motor signals to the skeletal muscles. The lateral horn, which is only found in the thoracic, upper lumbar, and sacral regions, is the central component of the sympathetic division of the autonomic nervous system. Some of the largest neurons of the spinal cord are the multipolar motor neurons in the anterior horn. The fibers that cause contraction of skeletal muscles are the axons of these neurons. The motor neuron that causes contraction of the big toe, for example, is located in the sacral spinal cord. The axon that has to reach all the way to the belly of that muscle may be a meter in length. The neuronal cell body that maintains that long fiber must be quite large, possibly several hundred micrometers in diameter, making it one of the largest cells in the body. Q: What type of matter in the spinal cord has the appearance of an ink-blot test and is subdivided into regions that are referred to as horns? Choices: - bright matter - wet matter - dark matter - gray matter A:
**Answer**
gray matter
