Answer the following question given this paragraph: In everyday speech, the terms accuracy and precision are frequently used interchangeably. However, their scientific meanings are quite different. Accuracy is a measure of how close a measurement is to the correct or accepted value of the quantity being measured. Precision is a measure of how close a series of measurements are to one another. Precise measurements are highly reproducible, even if the measurements are not near the correct value. Q: In contrast to precision, this term means how close a measurement is to the correct or accepted value of the quantity being measured? Choices: - diversity - frequency - deviant - accuracy A:
accuracy

Answer the following question given this paragraph: 38.4 Muscle Contraction and Locomotion The body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Skeleton muscle tissue is composed of sarcomeres, the functional units of muscle tissue. Muscle contraction occurs when sarcomeres shorten, as thick and thin filaments slide past each other, which is called the sliding filament model of muscle contraction. ATP provides the energy for cross-bridge formation and filament sliding. Regulatory proteins, such as troponin and tropomyosin, control cross-bridge formation. Excitationcontraction coupling transduces the electrical signal of the neuron, via acetylcholine, to an electrical signal on the muscle membrane, which initiates force production. The number of muscle fibers contracting determines how much force the whole muscle produces. Q: The body contains how many types of muscle tissue? Choices: - two - seven - four - three A:
(Answer)
three

(Q).
Answer the following question given this paragraph: Acceleration is a vector, and thus has a both a magnitude and direction. Acceleration can be caused by either a change in the magnitude or the direction of the velocity. Instantaneous acceleration a is the acceleration at a specific instant in time. Deceleration is an acceleration with a direction opposite to that of the velocity. Q: Acceleration is a vector, and thus has a both a magnitude and what else? Choices: - temperature - pressure - wavelength - direction A:
(A).
direction
Ques:Answer the following question given this paragraph: A mineral is a solid material that forms by a natural process. A mineral can be made of an element or a compound. It has a specific chemical composition. Its chemical composition is different from other minerals. Each type of mineral has physical properties that differ from others. These properties include crystal structure, hardness, density, and color. For example, silver is a soft, shiny metal. Salt is a white, cube-shaped crystal. Diamond is an extremely hard, translucent crystal. Q: What is the general name for a solid material that is formed via a natural process? Choices: - chemical - gas - plasma - mineral A:

Ans:mineral
