From a logical standpoint, I think the violinist, Henry Fonda, chocolate box and seed metaphors were all valid.The violinist example illustrates the difference between what one has a right to and what is a kindness or act of charity as do the Henry Fonda chocolate box metaphors. They both also include discussion of the level of inconvenience and harm. Thomson asserts that many would think it less immoral to refuse help in...

How does your body use the protein once it has been ingested? Consider the following statements and select the correct ones regarding protein use. Select all that apply. ► View Available Hint(s) Amino acids are used to create new proteins. If you ingest more protein than your body needs, the protein is stored in muscle. The liver uses amino acids to create glucose. If calorie intake is inadequate, amino acids can be used for production of energy In this activity,...

3. Unpolluted rain has an approximate pH of 5.5. Natural emissions (from volcanoes and lightning), and human activity (from mining and industrial plants) emit compounds that mix with water vapor in the atmosphere to create "acid rain," which can have a pH-4.5. Referring to the pH equation, explain why decreasing pH numbers mean that the acidity is increasing. a. Referring to the pH equation, explain why more acidic solutions have lower pH values. b. Referring to the pH equation, explain...

Question 8 The nylon rope from which a mountain climber is suspended has a force constant of 1.40 x 104 N/m. How much would this rope stretch to break the climber's fall if he free-falls 2.16 m before the rope runs out of slack, given his mass plus and the mass of his equipment are 91.6 kg? Hint: Use conservation of energy. You can assume the amount the rope stretches is small compared to the distance of his fall. Select...
