Answer the following question given this paragraph: Visible light is light that has wavelengths that can be detected by the human eye. The wavelength of visible light determines the color that the light appears. As you can see in the Figure below , light with the longest wavelength appears red, and light with the shortest wavelength appears violet. In between are all the other colors of light that we can see. Only seven main colors of light are actually represented in the diagram. Q: Visible light has what that can be detected by the human eye? Choices: - patterns - dimensions - colors - wavelengths A:
wavelengths
Answer the following question given this paragraph: When using the lens makers equation, remember that real things get positive numbers and virtual things get negative numbers. Thus, diverging lenses and virtual images get negative numbers. The object distance is always positive. Q: In the lens makers' equation, diverging lenses and virtual images are associated with what kinds of numbers? Choices: - positive numbers - variable numbers - fractional numbers - negative numbers A:
negative numbers
Q: Answer the following question given this paragraph: Q: If environmental conditions deteriorate, many species can form protective what? Choices: - fibers - proteins - shells - cysts A:
A: cysts
Question: Answer the following question given this paragraph: Because of their freely moving electrons, metals are good conductors of electricity. Metals also can be shaped without breaking. They are ductile (can be shaped into wires) and malleable (can be shaped into thin sheets). Metals have these properties because of the nature of their metallic bonds. Q: The nature of what gives metals the properties of being ductile and malleable? Choices: - liquid bonds - magneticism - titanium bonds - metallic bonds A:
Answer: metallic bonds

Answer the following question given this paragraph: Energy from the Sun has a wide range of wavelengths. The total range of energy is called the electromagnetic spectrum ( Figure below ). Q: What is the total range of the energy from the sun called? Choices: - molecular spectrum - solar spectrum - measured spectrum - electromagnetic spectrum A:
**Answer**
electromagnetic spectrum
Answer the following question given this paragraph: Pillow lava is created from lava that enters the water. The volcanic vent may be underwater. The lava may flow over land and enter the water ( Figure below ). Once in the water, the lava cools very quickly. The lava forms round rocks that resemble pillows. Pillow lava is particularly common along mid-ocean ridges. Q: Lava that enters the water is called what? Choices: - lava flow - magma runoff - saltwater lava - pillow lava A:
pillow lava
