Q: Q: When a series of measurements is precise but not what, the error is usually systematic? Read this paragraph and choose the correct option from the provided answers: 0 .033 g 1 .117 g 100 = 3 .0% When a series of measurements is precise but not accurate, the error is usually systematic. Systematic errors can be caused by faulty instrumentation or faulty technique. The difference between accuracy and precision is demonstrated in Skill Builder ES7. Choices: - velocity - length - color - accurate A:
A: accurate

Q: Q: The shapes of minerals form as they are broken along what planes? Read this paragraph and choose the correct option from the provided answers: Minerals can form various shapes. Polygons are pictured below ( Figure below ). The shapes form as the minerals are broken along their cleavage planes. Cleavage planes determine how the crystals can be cut to make smooth surfaces. People who cut gemstones follow cleavage planes. Diamonds and emeralds can be cut to make beautiful gemstones. Choices: - parallel planes - sedimentary planes - calcium planes - cleavage planes A:
A: cleavage planes

Q: Q: Asthma, pneumonia, and emphysema are diseases of what system? Read this paragraph and choose the correct option from the provided answers: Diseases of the respiratory system include asthma, pneumonia, and emphysema. Choices: - reproductive - pulmonary - digestive - respiratory A:
A: respiratory

Q: Q: For photosynthesis to begin, the inputs required are sunlight, water, and what? Read this paragraph and choose the correct option from the provided answers: Recall that the only required ingredients needed for photosynthesis are sunlight, carbon dioxide (CO 2 ), and water (H 2 O). From these simple inorganic ingredients, photosynthetic organisms produce the carbohydrate glucose (C 6 H 12 O 6 ), and other complex organic compounds. Essentially, these producers are changing the energy from the sunlight into a usable form of energy. They are also making the oxygen that we breathe. Oxygen is a waste product of photosynthesis. Choices: - phosphorus dioxide - methane - sulfur dioxide - carbon dioxide A:
A: carbon dioxide
