Answer the following question given this paragraph: Members of the genus Trypanosoma are flagellate protozoa that cause sleeping sickness , which is common in Africa. They also cause Chagas disease , which is common in South America. The parasites are spread by insect vectors. The vector for Chagas disease is shown in Figure below . Trypanosoma parasites enter a person's blood when the vector bites. Then they spread to other tissues and organs. The diseases may be fatal without medical treatment. Q: Members of the genus trypanosoma are flagellate protozoa that cause what? Choices: - cancer - hypertension - mutations - sleeping sickness A:
sleeping sickness

Question: Answer the following question given this paragraph: 10.3 Muscle Fiber Contraction and Relaxation A sarcomere is the smallest contractile portion of a muscle. Myofibrils are composed of thick and thin filaments. Thick filaments are composed of the protein myosin; thin filaments are composed of the protein actin. Troponin and tropomyosin are regulatory proteins. Muscle contraction is described by the sliding filament model of contraction. ACh is the neurotransmitter that binds at the neuromuscular junction (NMJ) to trigger depolarization, and an action potential travels along the sarcolemma to trigger calcium release from SR. The actin sites are exposed after Ca++ enters the sarcoplasm from its SR storage to activate the troponin-tropomyosin complex so that the tropomyosin shifts away from the sites. The cross-bridging of myposin heads docking into actin-binding sites is followed by the "power stroke"the sliding of the thin filaments by thick filaments. The power strokes are powered by ATP. Ultimately, the sarcomeres, myofibrils, and muscle fibers shorten to produce movement. Q: What is the smallest contractile portion of a muscle? Choices: - filaments - cell - capillary - sarcomere A:
Answer: sarcomere

Answer the following question given this paragraph: The four planets closest to the SunMercury, Venus, Earth, and Marsare the inner planets or terrestrial planets ( Figure below ). They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets. Q: Where are the terrestrial planets located, in relation to the sun? Choices: - farthest - To the left - To the right - closest A:
**Answer**
closest
