Answer the following question given this paragraph: Muscles That Move the Humerus Similar to the muscles that position the pectoral girdle, muscles that cross the shoulder joint and move the humerus bone of the arm include both axial and scapular muscles (Figure 11.23 and Figure 11.24). The two axial muscles are the pectoralis major and the latissimus dorsi. The pectoralis major is thick and fan-shaped, covering much of the superior portion of the anterior thorax. The broad, triangular latissimus dorsi is located on the inferior part of the back, where it inserts into a thick connective tissue shealth called an aponeurosis. Q: Which muscle is broad, triangular and located on the inferior part of the back where it inserts into the aponeurosis? Choices: - bronchus dorsi - dorsolateral dorsi - Synergistic dorsi - latissimus dorsi A:
(Answer)
latissimus dorsi
Ques: Answer the following question given this paragraph: Another way ocean water moves is in currents. A current is a stream of moving water that flows through the ocean. Surface currents are caused mainly by winds, but not the winds that blow and change each day. Surface currents are caused by the major wind belts that blow in the same direction all the time. Q: What is a stream of moving water that flows through the ocean? Choices: - creek - tidal wave - waterfall - current A:
Ans: current

Answer the following question given this paragraph: Chemical digestion could not take place without the help of digestive enzymes and other substances secreted into the GI tract. An enzyme is a protein that speeds up a biochemical reaction. Digestive enzymes speed up the reactions of chemical digestion. Table below lists a few digestive enzymes, the organs that produce them, and their functions in digestion. Q: What speeds up the reactions of chemical digestion? Choices: - protein catalysts - electrical enzymes - stomach acids - digestive enzymes A:
(A).
digestive enzymes
Ques:Answer the following question given this paragraph: Why are so many amphibian species threatened by extinction, and why should you care? The second question is easy. Amphibians control pests, may be a source of new medicines, and help feed many other animals. The nature of amphibian skin may help explain why so many amphibian species are at risk. Their skin easily absorbs substances from the environment, such as pollutants in water or air. Therefore, they may suffer from poor environmental quality before other animals do. As such, they may provide an early-warning system of environmental damage. Q: Which part of the body of amphibians, easily absorbs substances from the environment? Choices: - liver - scales - Eyes - skin A:

Ans:skin
Answer the following question given this paragraph: Summary A measure of the disorder of a system is its entropy (S), a state function whose value increases with an increase in the number of available microstates. Areversible process is one for which all intermediate states between extremes are equilibrium states; it can change direction at any time. In contrast, anirreversible process occurs in one direction only. The change in entropy of the system or the surroundings is the quantity of heat transferred divided by the temperature. The second law of thermodynamics states that in a reversible process, the entropy of the universe is constant, whereas in an irreversible process, such as the transfer of heat from a hot object to a cold object, the entropy of the universe increases. Q: A measure of the disorder of a system is called its what? Choices: - lose - spectral - function - entropy A:
entropy
