Answer the following question given this paragraph: Currents also flow deep below the surface of the ocean. Deep currents are caused by differences in density at the top and bottom. More dense water takes up less space than less dense water. It has the same mass but less volume. Water that is more dense sinks. Less dense water rises. What can make water more dense?. Q: What is caused by differences in density at the top and bottom of the ocean? Choices: - shallow currents - still water - flat currents - deep currents A:
deep currents

Ques: Answer the following question given this paragraph: Figure 16.12 The arteries of the body, indicated in red, start at the aortic arch and branch to supply the organs and muscles of the body with oxygenated blood. The veins of the body, indicated in blue, return blood to the heart. The pulmonary arteries are blue to reflect the fact that they are deoxygenated, and the pulmonary veins are red to reflect that they are oxygenated. (credit: modification of work by Mariana Ruiz Villareal). Q: What does the blue color of the pulmonary arteries reflect? Choices: - they are lost - they are oxygenated - they are done - they are deoxygenated A:
Ans: they are deoxygenated

Answer the following question given this paragraph: In radio broadcasts, sounds are encoded in radio waves by changing either the amplitude (AM) or frequency (FM) of the waves. The encoded waves are broadcast from a tower and changed back to sounds by radio receivers. Q: What changes encoded waves which are being broadcast into sounds? Choices: - transmitters - amplifiers - band receivers - radio receivers A:
(A).
radio receivers

Answer the following question given this paragraph: 5.3 Functions of the Integumentary System The skin plays important roles in protection, sensing stimuli, thermoregulation, and vitamin D synthesis. It is the first layer of defense to prevent dehydration, infection, and injury to the rest of the body. Sweat glands in the skin allow the skin surface to cool when the body gets overheated. Thermoregulation is also accomplished by the dilation or constriction of heat-carrying blood vessels in the skin. Immune cells present among the skin layers patrol the areas to keep them free of foreign materials. Fat stores in the hypodermis aid in both thermoregulation and protection. Finally, the skin plays a role in the synthesis of vitamin D, which is necessary for our well-being but not easily available in natural foods. Q: What system, which includes the skin, plays important roles in protection, sensing stimuli and thermoregulation? Choices: - digestive system - pectins system - teleporters system - integumentary system A:
integumentary system
