Q: What paired organs help regulate blood pressure through sodium ion and water retention and loss? Read this paragraph and choose the correct option from the provided answers: 25.10 The Urinary System and Homeostasis The effects of failure of parts of the urinary system may range from inconvenient (incontinence) to fatal (loss of filtration and many others). The kidneys catalyze the final reaction in the synthesis of active vitamin D that in turn helps regulate Ca++. The kidney hormone EPO stimulates erythrocyte development and promotes adequate O2 transport. The kidneys help regulate blood pressure through Na+ and water retention and loss. The kidneys work with the adrenal cortex, lungs, and liver in the reninangiotensinaldosterone system to regulate blood pressure. They regulate osmolarity of the blood by regulating both solutes and water. Three electrolytes are more closely regulated than others: Na+, Ca++, and K+. The kidneys share pH regulation with the lungs and plasma buffers, so that proteins can preserve their three-dimensional conformation and thus their function. Choices: - lungs - tissues - lymph nodes - kidneys A:
kidneys

Q: How do oceans help control global warming? Read this paragraph and choose the correct option from the provided answers: Ocean water also absorbs gases from the atmosphere. The most important are oxygen and carbon dioxide. Oxygen is needed by living things in the oceans. Much of the carbon dioxide sinks to the bottom of the seas. Carbon dioxide is a major cause of global warming. By absorbing carbon dioxide, the oceans help control global warming. Choices: - releasing oxygen - reflecting light - Cooling air - absorbing carbon dioxide A:
absorbing carbon dioxide

Q: In winter, water does what, becoming solid and causing hoses to rupture and engine blocks to crack? Read this paragraph and choose the correct option from the provided answers: In the winter, the temperature often gets well below the freezing point of water. This condition can create problem in car radiators. If the water freezes, water hoses will break, the engine block can crack, and significant damage can be done to the car. Choices: - crystallizes - shrinks - fractures - freeze A:
