Answer the following question given this paragraph: View the University of Michigan WebScope at http://virtualslides. umich. edu/Histology/EMsmallCharts/ 3%20Image%20Scope%20finals/054%20-%20Peripheral%20nerve_001. svs/view. apml?listview=1& (http://openstaxcollege. org/l/nervefiber) to see an electron micrograph of a cross-section of a myelinated nerve fiber. The axon contains microtubules and neurofilaments that are bounded by a plasma membrane known as the axolemma. Outside the plasma membrane of the axon is the myelin sheath, which is composed of the tightly wrapped plasma membrane of a Schwann cell. What aspects of the cells in this image react with the stain to make them a deep, dark, black color, such as the multiple layers that are the myelin sheath?. Q: The axon contains microtubules and neurofilaments that are bounded by a plasma membrane known as what? Choices: - exolemal - axolenon - xerophyte - axolemma A:
axolemma

Answer the following question given this paragraph: Another simple machine that uses a wheel is the pulley. A pulley is a simple machine that consists of a rope and grooved wheel. The rope fits into the groove in the wheel, and pulling on the rope turns the wheel. Figure below shows two common uses of pulleys. Q: A pulley is a simple machine that consists of a grooved wheel and? Choices: - a battery - a wedge - a lever - a rope A:
(Answer)
a rope
Ques: Answer the following question given this paragraph: When light rays converge behind a lens, a real image is formed. Real images are useful in that you can place photographic film at the physical location of the real image, expose the film to the light, and make a two-dimensional representation of the world, a photograph. Q: What can be formed by converging light rays behind a lens, onto a piece of film? Choices: - a prism - a kaleidoscope - a mirror - a photograph A:
Ans: a photograph

Ques:Answer the following question given this paragraph: Archaea that live in extremely hot environments are called thermophiles. Q: What are archaea that live in extremely hot environments called? Choices: - hypothermic - hemophiliacs - tardigrades - thermophiles A:

Ans:thermophiles
Answer the following question given this paragraph: Food Chains. These two food chains represent complex systems in nature. They make the systems easier to understand. These are simple conceptual models. Models of very complex systems are often based on mathematical equations or computer simulations. Q: What kind of tool, often based on mathematical equations or computer simulations, helps us understand complex systems? Choices: - levels - planes - panels - models A:
models
