Answer the following question given this paragraph: CRITICAL THINKING QUESTIONS 19. How are neurons similar to other cells? How are they unique? 20. Multiple sclerosis causes demyelination of axons in the brain and spinal cord. Why is this problematic?. Q: The existence of (virtual) photons is possible only by virtue of the heisenberg uncertainty principle and can travel an unlimited distance, so the range ofthe electromagnetic for is what? Choices: - finite - simple - generated - infinite A:
infinite
Answer the following question given this paragraph: Q: When light meets matter, it may be reflected, transmitted, or what? Choices: - diffuse - reflected - diffracted - absorbed A:
absorbed
Q: Answer the following question given this paragraph: The only light that people can see is called visible light . It refers to a very narrow range of wavelengths in the electromagnetic spectrum that falls between infrared light and ultraviolet light. Within the visible range, we see light of different wavelengths as different colors of light, from red light, which has the longest wavelength, to violet light, which has the shortest wavelength. You can see the spectrum of colors of visible light in Figure below . When all of the wavelengths are combined, as they are in sunlight, visible light appears white. You can learn more about visible light in the chapter "Visible Light" and at the URL below. Q: Where does visible light fall in between on the electromagnetic spectrum? Choices: - infrared light and specific light - infrared light and gamma ray - radio and infrared - infrared light and ultraviolet light A:
A: infrared light and ultraviolet light
Question: Answer the following question given this paragraph: Mercury is the smallest planet and the closest to the Sun. It has an extremely thin atmosphere so surface temperatures range from very hot to very cold. Like the Moon, it is covered with craters. Q: What is the smallest planet in our solar system? Choices: - Earth - Jupiter - Mars - mercury A:
Answer: mercury

Answer the following question given this paragraph: The weathering of rocks and minerals can be mechanical or chemical. Mechanical weathering changes the size of a mineral or rock. Mechanical weathering does not change the chemical composition of that material. Chemical weathering changes the composition of a mineral or rock. Different types of weathering can alter the same material. Soil forms on top of rock. The type of soil that forms depends on the environment of the region. For example, warm and wet climates form different soils than cold and dry climates. A profile through the soil shows different horizons. Topsoil is the most important layer for crops. Water, ice, wind, and gravity create or modify landforms on Earth's surface. These agents can erode or deposit features that indicate their presence. Erosion by water and ice lowered and rounded the Appalachians. These old mountains no longer look like the Himalaya. Someday the Himalaya may look like the Appalachians do now. Q: What kind of weathering changes the size of a mineral or rock but does not change its chemical composition? Choices: - molecular weathering - chemical reaction - radiation - mechanical weathering A:
**Answer**
mechanical weathering
