Answer the following question given this paragraph: Well maybe not yours. But some other person's. Hair is an integral part of the integumentary system. And although many people may lose some or all of the hair on top of their head, they still have hair on their arms and legs that perform important functions. Q: Hair is a component of which bodily system? Choices: - circulatory - relatable system - trypeta system - integumentary system A:
integumentary system
Answer the following question given this paragraph: Visible Light Visible light is the narrow segment of the electromagnetic spectrum to which the normal human eye responds. Visible light is produced by vibrations and rotations of atoms and molecules, as well as by electronic transitions within atoms and molecules. The receivers or detectors of light largely utilize electronic transitions. We say the atoms and molecules are excited when they absorb and relax when they emit through electronic transitions. Figure 24.16 shows this part of the spectrum, together with the colors associated with particular pure wavelengths. We usually refer to visible light as having wavelengths of between 400 nm and 750 nm. (The retina of the eye actually responds to the lowest ultraviolet frequencies, but these do not normally reach the retina because they are absorbed by the cornea and lens of the eye. ) Red light has the lowest frequencies and longest wavelengths, while violet has the highest frequencies and shortest wavelengths. Blackbody radiation from the Sun peaks in the visible part of the spectrum but is more intense in the red than in the violet, making the Sun yellowish in appearance. Q: Visible light is the narrow segment of what, to which the normal human eye responds? Choices: - molecular spectrum - radio spectrum - phenomena spectrum - electromagnetic spectrum A:
electromagnetic spectrum

Answer the following question given this paragraph: Surface waves travel along the ground outward from an earthquake's epicenter. Surface waves are the slowest of all seismic waves. They travel at 2.5 km (1.5 miles) per second. There are two types of surface waves. Love waves move side-to-side, much like a snake. Rayleigh waves produce a rolling motion as they move up and backwards ( Figure above ). Surface waves cause objects to fall and rise, while they are also swaying back and forth. These motions cause damage to rigid structures during an earthquake. Q: What type of waves are the slowest of all seismic waves? Choices: - core waves - thick waves - central waves - surface waves A:
**Answer**
surface waves
(Q).
Answer the following question given this paragraph: Sulfur oxides include sulfur dioxide (SO 2 ) and sulfur trioxide (SO 3 ). Sulfur oxides are produced when sulfur and oxygen combine. This happens when coal burns. Coal can contain up to 10 percent sulfur. Q: What is produced when sulfur and oxygen combine? Choices: - treatment oxides - Solid oxides - ethanol oxides - sulfur oxides A:
(A).
sulfur oxides
