Q: Answer the following question given this paragraph: Combustion reactions involve the reaction of a hydrocarbon with oxygen gas to produce water and carbon dioxide. Q: What involves the reaction of a hydrocarbon with oxygen gas to produce water and carbon dioxide? Choices: - hydrogen reactions - chemical reactions - material reactions - combustion reactions A:
A: combustion reactions

Q: Answer the following question given this paragraph: Creep is the very slow movement of rock and soil down a hillside. Creep occurs so slowly you can't see it happening. You can only see the effects of creep after years of movement ( Figure below ). The slowly moving ground causes trees, fence posts, and other structures on the surface to tilt downhill. Q: What is the apt term for the very slow movement of rock and soil down a hillside? Choices: - glide - landslide - drop - creep A:
A: creep

Q: Answer the following question given this paragraph: Aquatic arthropods use gills to exchange gases. These gills have a large surface area in contact with the water, so they can absorb more oxygen. Q: What do aquatic arthropods use to exchange gases? Choices: - lungs - pores - diaphragm - gills A:
A: gills

Q: Answer the following question given this paragraph: Glial Cells of the PNS One of the two types of glial cells found in the PNS is the satellite cell. Satellite cells are found in sensory and autonomic ganglia, where they surround the cell bodies of neurons. This accounts for the name, based on their appearance under the microscope. They provide support, performing similar functions in the periphery as astrocytes do in the CNSexcept, of course, for establishing the BBB. The second type of glial cell is the Schwann cell, which insulate axons with myelin in the periphery. Schwann cells are different than oligodendrocytes, in that a Schwann cell wraps around a portion of only one axon segment and no others. Oligodendrocytes have processes that reach out to multiple axon segments, whereas the entire Schwann cell surrounds just one axon segment. The nucleus and cytoplasm of the Schwann cell are on the edge of the myelin sheath. The relationship of these two types of glial cells to ganglia and nerves in the PNS is seen in Figure 12.12. Q: Satellite and schwann cells are the two types of what kind of cell found in the pns? Choices: - dendritic - osteoclast - epidermal - glial A:
A: glial
