Answer the following question given this paragraph: Migration refers to seasonal movements of animals from one area to another. Migrants typically travel long distances, and travel the same paths each seasonal cycle. Usually, the migrants move to another area in order to find food or mates. Many birds, fish, and insects migrate. Mammals such as whales and caribou migrate as well. Figure below shows the migration route of a bird called a godwit. Another example of a behavior with a yearly cycle is hibernation. Hibernation is a state in which an animal's body processes are slower than usual, and its body temperature falls. An animal uses less energy than usual during hibernation. This helps the animal survive during a time of year when food is scarce. Hibernation may last for weeks or months. Animals that hibernate include species of bats, squirrels, and snakes. Most people think that bears hibernate. In fact, bears do not go into true hibernation. In the winter, they go into a deep sleep. However, their body processes do not slow down very much. Their body temperature also remains about the same as usual. Bears can be awakened easily from their winter sleep. Q: The seasonal movements of animals from one area to another is referred to as? Choices: - mitigation - hybernation - echolocation - migration A:
(Answer)
migration

(Question)
Answer the following question given this paragraph: Why is this picture of a cat so colorful? No cat looks like this to the human eye. The picture was taken with a special camera that senses infrared light. This is a form of energy given off by warm objects. Areas that appear yellow are the warmest, and areas that appear purple are the coolest. The picture shows that the cat's eyes are the warmest part of its head. Why can't people see images like this without a camera? The answer has to do with the wavelengths of infrared light. Its wavelengths are too long for the human eye to detect. In fact, the human eye can detect light only in a very narrow range of wavelengths, called visible light. You'll learn more about infrared light, visible light, and other forms of electromagnetic radiation in this chapter. Q: The entire range of light that can be seen by the human eye without aid is known as what kind of light? Choices: - white light - colored light - infrared light - visible light A:
(Answer)
visible light

(Question)
Answer the following question given this paragraph: Most flatworms have a distinct head region that includes nerve cells and sensory organs, such as eyespots. The development of a head region, called cephalization , evolved at the same time as bilateral symmetry in animals. This process does not occur in cnidarians, which evolved prior to flatworms and have radial symmetry. Q: The development of a head region is called what? Choices: - trichina - spore - cocklebur - cephalization A:
(Answer)
cephalization
