Q: 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:
A: three

Q: Answer the following question given this paragraph: Deductive reasoning means making a specific statement based on a general principle. Q: Making a specific statement based on a general principle is the definition of what type of reasoning? Choices: - inductive - inference - transitive - deductive A:
A: deductive

Q: Answer the following question given this paragraph: Genetics is the branch of biology that focuses on heredity in organisms. Q: Genetics is the branch of biology that focuses on heredity in what? Choices: - schools - fruits - vacuums - organisms A:
A: organisms

Q: Answer the following question given this paragraph: If the rocks on one or both sides of a fracture move, the fracture is called a fault ( Figure below ). Faults can occur alone or in clusters, creating a fault zone . Earthquakes happen when rocks break and move suddenly. The energy released causes an earthquake. Q: What is it called when multiple faults are located in close proximity to one another? Choices: - fog zone - crystal zone - solid zone - fault zone A:
A: fault zone
