Answer the following question given this paragraph: Superposition refers to the position of rock layers and their relative ages ( Figure below ). Relative age means age in comparison with other rocks, either younger or older. The relative ages of rocks are important for understanding Earth's history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition. Q: Deeper layers of rock must be older than layers closer to the surface, this is the law of what? Choices: - erosion - diffraction - flux - superposition A:
superposition
Answer the following question given this paragraph: In biological systems, matter is continuously changing states as well. For example, carbon in the form of the gas carbon dioxide is changed into glucose, a solid. This change, of course, occurs during photosynthesis. During cellular respiration, carbons from the glucose molecule are changed back into the carbon dioxide gas. Q: During cellular respiration, carbons from the glucose molecule are changed back into what gas? Choices: - deformation dioxide - carbon monoxide - liquid dioxide - carbon dioxide A:
carbon dioxide
Q: Answer the following question given this paragraph: Some insects, such as aphids, have piercing-sucking mouthparts. Other insects, like grasshoppers, have chewing mouthparts. Q: What kind of mouthparts do aphids have? Choices: - chewing mouthparts - sponging mouthparts - siphoning mouthparts - piercing-sucking mouthparts A:
A: piercing-sucking mouthparts
Question: Answer the following question given this paragraph: Solstice refers to the position of the Sun when it is closest to one of the poles. At equinox, the Sun is directly over the Equator. Q: When is the sun directly over the equator? Choices: - Winter - Midsummer - Fall - equinox A:
Answer: equinox

Answer the following question given this paragraph: 5.2 Drag Forces 5. Athletes such as swimmers and bicyclists wear body suits in competition. Formulate a list of pros and cons of such suits. Two expressions were used for the drag force experienced by a moving object in a liquid. One depended upon the speed, while the other was proportional to the square of the speed. In which types of motion would each of these expressions be more applicable than the other one? 7. As cars travel, oil and gasoline leaks onto the road surface. If a light rain falls, what does this do to the control of the car? Does a heavy rain make any difference? 8. Why can a squirrel jump from a tree branch to the ground and run away undamaged, while a human could break a bone in such a fall?. Q: Athletes such as swimmers and bicyclists wear body suits in competition to minimize what forces? Choices: - natural forces - rolling forces - activity forces - drag forces A:
**Answer**
drag forces

Answer the following question given this paragraph: The skin has multiple roles in the body. Many of these roles are related to homeostasis. The skin's main functions are preventing water loss from the body and serving as a barrier to the entry of microorganisms. In addition, melanin in the skin blocks UV light and protects deeper layers from its damaging effects. Q: The skin plays an important role in preventing the escape of what commonly found liquid from the body? Choices: - hormones - stomach acid - urine - water A:
**Answer**
water
