Answer the following question given this paragraph: Chapter 38 1 Figure 38.19B 3 Figure 38.38 In the presence of Sarin, acetycholine is not removed from the synapse, resulting in continuous stimulation of the muscle plasma membrane. At first, muscle activity is intense and uncontrolled, but the ion gradients dissipate, so electrical signals in the T-tubules are no longer possible. The result is paralysis, leading to death by asphyxiation. 4 A 6 D 8 B 10 A 12 B 14 C 16 D 18 D 20 The female pelvis is tilted forward and is wider, lighter, and shallower than the male pelvis. It is also has a pubic angle that is broader than the male pelvis. 22 Compact bone tissue forms the hard external layer of all bones and consists of osteons. Compact bone tissue is prominent in areas of bone at which stresses are applied in only a few directions. Spongy bone tissue forms the inner layer of all bones and consists of trabeculae. Spongy bone is prominent in areas of bones that are not heavily stressed or at which stresses arrive from many directions. 24 The hip joint is flexed and the knees are extended. 26 Because ATP is required for myosin to release from actin, muscles would remain rigidly contracted until more ATP was available for the myosin cross-bridge release. This is why dead vertebrates undergo rigor mortis. 28 Neurons will not be able to release neurotransmitter without calcium. Skeletal muscles have calcium stored and don't need any from the outside. Q: What kind of tissue consists of trabeculae and forms the inner layer of all bones? Choices: - flotsam bone tissue - denser bone tissue - corregated bone tissue - spongy bone tissue A:
spongy bone tissue

Answer the following question given this paragraph: simple sugar that all living things use to store and transport energy. Q: What is the simple sugar that living things us to store energy? Choices: - nicotine - brown - chloride - glucose A:
(Answer)
glucose
Ques: Answer the following question given this paragraph: Compounds that contain mainly the elements carbon and hydrogen are called organic compounds . This is because they are found mainly in living organisms. Most organic compounds are held together by covalent bonds. An example of an organic compound is glucose (C 6 H 12 O 6 ), which is shown in Figure below . Glucose is a simple sugar that living cells use for energy. All other compounds are called inorganic compounds. Water is an example of an inorganic compound. Q: Compounds that contain mainly the elements carbon and hydrogen are called what kind of compounds? Choices: - microscopic compounds - reactive compounds - natural compounds - organic compounds A:
Ans: organic compounds
(Q).
Answer the following question given this paragraph: A mutation that changes all or a large part of a chromosome is called a chromosomal mutation. This type of mutation tends to be very serious. Sometimes chromosomes are missing or extra copies are present. An example is the mutation that causes Down syndrome. In this case, there is an extra copy of one of the chromosomes. Q: What is a mutation that changes all or much of a particular chromosome? Choices: - kinetic mutation - biochemical mutation - muscular mutation - chromosomal mutation A:
(A).
chromosomal mutation
Ques:Answer the following question given this paragraph: 19.5 Capacitors and Dielectrics A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure 19.13. (Most of the time an insulator is used between the two plates to provide separationsee the discussion on dielectrics below. ) When battery terminals are connected to an initially uncharged capacitor, equal amounts of positive and negative charge, +Q and Q , are separated into its two plates. The capacitor remains neutral overall, but we refer to it as storing a charge. Q: What do we call a device used to store electric charge? Choices: - charger - amplifier - battery - capacitor A:

Ans:capacitor
Ques: Answer the following question given this paragraph: There are several dietary sources of carbohydrates. Starch is found in many vegetables (especially potatoes) and baked goods. Sucrose (table sugar) is included as part of many prepared foods. Lactose is found in milk products, and maltose is present in some vegetables. Q: What is the chemical name of table sugar? Choices: - potassium - codeine - cellulose - sucrose A:
Ans:
sucrose
