Q: What property is the result of the force of gravity being opposed by the normal force? Read this paragraph and choose the correct option from the provided answers: For a full description of weight, look at Forces: Mass versus Weight. In sum, weight is the result of the force of gravity being opposed by the normal force. As we just learned, objects in orbit are in freefall; they have nothing exerting a normal force against them and thus no weight. Choices: - light - density - sound - weight A:
weight

Q: Corals build hard exoskeletons that grow to become what? Read this paragraph and choose the correct option from the provided answers: Choices: - algae - stability reefs - fungi - coral reefs A:
coral reefs

Q: Q: Of the three basic types of emissions, which has the highest penetrating power? Read this paragraph and choose the correct option from the provided answers: Of the three basic types of emissions, gamma radiation has the highest penetrating power. Thick, high density materials (such as lead) are required to stop gamma emissions. The thickness of the shielding will determine the effectiveness of the protection offered by the lead. Choices: - ultraviolet radiation - fluid radiation - chemical radiation - gamma radiation A:
A: gamma radiation

Question: Q: What is the shorter loop of the cardiovascular system? Read this paragraph and choose the correct option from the provided answers: Pulmonary circulation is the shorter loop of the cardiovascular system. It carries blood between the heart and lungs. Oxygen-poor blood flows from the heart to the lungs. In the lungs, the blood absorbs oxygen and releases carbon dioxide. Then the oxygen-rich blood returns to the heart. Choices: - pulmonary edema - venous circulation - metabolic circulation - pulmonary circulation A:
Answer: pulmonary circulation
