Answer the following question given this paragraph: The modern periodic table is based on atomic number. Elements in each period go from metals on the left to metalloids and then nonmetals on the right. Within groups, elements have similar properties. Q: What is the modern periodic table based on? Choices: - element mass - metallic number - element density - atomic number A:
atomic number
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
Q: Answer the following question given this paragraph: The plasma membrane may have extensions, such as whip-like flagella or brush-like cilia . In single-celled organisms, like those shown in Figure below , the membrane extensions may help the organisms move. In multicellular organisms, the extensions have other functions. For example, the cilia on human lung cells sweep foreign particles and mucus toward the mouth and nose. Q: In single-celled organisms, what does the plasma membrane extensions help the organisms to do? Choices: - increase - inspect - prevent - move A:
A: move
Question: Answer the following question given this paragraph: Breathing certainly is a major contribution to your health! Without breathing, we could not survive. Curiously, the act of breathing itself is little more than an application of Boyle's law. The lungs are a series of ever-narrowing tubes that end in a myriad of tiny sacs called alveoli. It is in the alveoli that oxygen from the air transfers to the bloodstream and carbon dioxide from the bloodstream transfers to the lungs for exhalation. For air to move in and out of the lungs, the pressure inside the lungs must change, forcing the lungs to change volumejust as predicted by Boyle's law. The pressure change is caused by the diaphragm, a muscle that covers the bottom of the lungs. When the diaphragm moves down, it expands the size of our lungs. When this happens, the air pressure inside our lungs decreases slightly. This causes new air to rush in, and we inhale. The pressure decrease is slightonly 3 torr, or about 0.4% of an atmosphere. We inhale only 0.51.0 L of air per normal breath. Exhaling air requires that we relax the diaphragm, which pushes against the lungs and slightly decreases the volume of the lungs. This slightly increases the pressure of the air in the lungs, and air is forced out; we exhale. Only 12 torr of extra pressure is needed to exhale. So with every breath, our own bodies are performing an experimental test of Boyle's law. Q: The lungs are a series of ever-narrowing tubes that end in a myriad of tiny sacs called what? Choices: - brachii - testes - glands - alveoli A:
Answer: alveoli
