In the future, electrical power may come from quantum nucleonics, a form of nuclear power that produces no residual radiation. The ability to use this form of power will require equipment adaptations, but it will solve the world's need for clean and efficient power. Companies that replace inefficient sources of power with quantum nucleonics only after they are required to by the Environmental Protection Agency are operating at a(n) ____ responsibility level. ? philanthropic ? economic ? cultural ? Legal ? ethical

You are studying the effects of a high protein, low carbohydrate diet on strength training (lifting weights) in athletes. Which of the following statements would be the best hypothesis to begin your study? Athletes on a high protein, low carbohydrate diet for 60 days will see a greater improvement in strength with training compared to athletes on a regular diet with training. For athletes doing strength training, a high protein, low carbohydrate is superior to a low protein, high carbohydrate diet. Athletes on high protein, low carbohydrate diet for 60 days will see greater improvement in strength with strength training than those without strength training. A high protein, low carbohydrate diet will provide more micronutrients for athletes than a regular diet.
