Answer the following question given this paragraph: Simon Cousins. Ice cubes in cola cause the cola to lose thermal energy . CC BY 2.0. Q: Ice cubes in cola cause the cola to lose what? Choices: - mechanical energy - kinetic energy - gravity - thermal energy A:
thermal energy
Answer the following question given this paragraph: Oxygen has 6 valence electrons in its ground state. Remember that ground state refers to the neutral atom in which the electrons occupy the lowest possible energy positions. Oxygen is two electrons away from being isoelectronic with the nearest noble gas. Oxygen will therefore form ions by gaining two electrons to become isoelectronic with neon, as shown below:. Q: What kind of energy positions do electrons occupy during ground state? Choices: - closest energy positions - relative energy positions - highest energy positions - lowest energy positions A:
lowest energy positions
Q: Answer the following question given this paragraph: Scientists refer to the vertical extent of ocean water as the water column . Two main zones based on depth of water are the photic zone and aphotic zone. The photic zone is the top 200 meters of water. The aphotic zone is water deeper than 200 meters. The deeper you go, the darker the water gets. That's because sunlight cannot penetrate very far under water. Sunlight is needed for photosynthesis. So the depth of water determines whether photosynthesis is possible. There is enough sunlight for photosynthesis only in the photic zone. Q: What is the vertical extent of ocean water called? Choices: - oceanic pillar - ocean column - water row - water column A:
A: water column
Question: Answer the following question given this paragraph: A more crucial use of RC circuits for timing purposes is in the artificial pacemaker, used to control heart rate. The heart rate is normally controlled by electrical signals generated by the sino-atrial (SA) node, which is on the wall of the right atrium chamber. This causes the muscles to contract and pump blood. Sometimes the heart rhythm is abnormal and the heartbeat is too high or too low. The artificial pacemaker is inserted near the heart to provide electrical signals to the heart when needed with the appropriate time constant. Pacemakers have sensors that detect body motion and breathing to increase the heart rate during exercise to meet the body's increased needs for blood and oxygen. Q: A more crucial use of rc circuits for timing purposes is in the artificial pacemaker, used to control what? Choices: - breathing rate - blood pressure - iron levels - heart rate A:
Answer: heart rate
