In monogamous systems, one male and one female are paired for at least one breeding season. In some animals, such as the gray wolf, these associations can last much longer, even a lifetime. Several explanations have been proposed for this type of. Q: In a monogamous pairing, a male individual is generally paired with what other type of individual in a sexual relationship? Choices: - worker - male - drone - female A:

Answer the following question given this paragraph: Besides entertaining a cat, laser light has many other uses. It is used to scan bar codes, for example, and to carry communication signals in optical fibers. Optical fibers are extremely thin glass tubes that are used to guide laser light (see Figure below ). Sounds or pictures are encoded in pulses of laser light, which are then sent through an optical fiber. All of the light reflects off the inside of the fiber, so none of it escapes. As a result, the signal remains strong even over long distances. More than one signal can travel through an optic fiber at the same time, as you can see in Figure below . Optical fibers are used to carry telephone, cable TV, and Internet signals. Q: What do optical fibres look like? Choices: - square boxes - big flashlights - flat paper - thin glass tubes A:
thin glass tubes
Q: Answer the following question given this paragraph: Atoms have equal numbers of positive protons and negative electrons, so they are neutral in electric charge. Q: Because atoms have equal numbers of positive protons and negative electrons, what kind of electric charge do they possess? Choices: - none - positive - negative - neutral A:
A: neutral
Question: Answer the following question given this paragraph: When an atomic nucleus decays, it does so by releasing one or more particles. The atom often (but not always) turns into a different element during the decay process. The amount of radiation given off by a certain sample of radioactive material depends on the amount of material, how quickly it decays, and the nature of the decay product. Big, rapidly decaying samples are most dangerous. Q: The atom often (but not always) turns into a different what during the decay process? Choices: - concept - reaction - aspect - element A:
Answer: element

Answer the following question given this paragraph: Blood flows through the heart in two separate loops. You can think of them as a "left side loop" and a "right side loop. " The right side of the heart collects oxygen-poor blood from the body and pumps it into the lungs, where it releases carbon dioxide and picks up oxygen. The left side carries the oxygen-rich blood back from the lungs into the left side of the heart, which then pumps the oxygen-rich blood to the rest of the body. The blood delivers oxygen to the cells of the body and returns to the heart oxygen-poor. Q: The right side of the heart collects what type of blood from the body? Choices: - oxygen-rich - dioxide-poor - potassium-rich - oxygen-poor A:
**Answer**
oxygen-poor
