Q: Answer the following question given this paragraph: Hyperparathyroidism results from an overproduction of parathyroid hormone. This results in excessive calcium being removed from bones and introduced into blood circulation, producing structural weakness of the bones, which can lead to deformation and fractures, plus nervous system impairment due to high blood calcium levels. Hypoparathyroidism, the underproduction of PTH, results in extremely low levels of blood calcium, which causes impaired muscle function and may result in tetany (severe sustained muscle contraction). The hormone calcitonin, which is produced by the parafollicular or C cells of the thyroid, has the opposite effect on blood calcium levels as does PTH. Calcitonin decreases blood calcium levels by inhibiting osteoclasts, stimulating osteoblasts, and stimulating calcium excretion by the kidneys. This results in calcium being added to the bones to promote structural integrity. Calcitonin is most important in children (when it stimulates bone growth), during pregnancy (when it reduces maternal bone loss), and during prolonged starvation (because it reduces bone mass loss). In healthy nonpregnant, unstarved adults, the role of calcitonin is unclear. Q: Hyperparathyroidism results from an overproduction of what? A:
Answer: parathyroid hormone

Answer the following question given this paragraph: The coordination sphere consists of the central metal ion or atom plus its attached ligands. Brackets in a formula enclose the coordination sphere; species outside the brackets are not part of the coordination sphere. The coordination number of the central metal ion or atom is the number of donor atoms bonded to it. The coordination number for the silver ion in [Ag(NH3)2]+ is two (Figure 19.14). For the copper(II) ion in [CuCl4]2, the coordination number is four, whereas for the cobalt(II) ion in [Co(H2O)6]2+ the coordination number is six. Each of these ligands is monodentate, from the Greek for "one toothed," meaning that they connect with the central metal through only one atom. In this case, the number of ligands and the coordination number are equal. Q: The coordination sphere consists of the central metal ion or atom plus its attached what? A:
OPTIONS:
- subunits
- strands
- molecules
- ligands
ligands

Answer the following question given this paragraph: The Pressure of a Mixture of Gases: Dalton's Law Unless they chemically react with each other, the individual gases in a mixture of gases do not affect each other's pressure. Each individual gas in a mixture exerts the same pressure that it would exert if it present alone in the container (Figure 9.20). The pressure exerted by each individual gas in a mixture is called its partial pressure. This observation is summarized by Dalton's law of partial pressures: The total pressure of a mixture of ideal gases is equal to the sum of the partial pressures of the component gases: P Total = P A + P B + P C + . = i P i In the equation PTotal is the total pressure of a mixture of gases, PA is the partial pressure of gas A; PB is the partial pressure of gas B; PC is the partial pressure of gas C; and so on. Q: According to dalton's law, unless they chemically react with each other, individual gases in a mixture of gases do not affect each other's what? A:
OPTIONS:
- mass
- weight
- density
- pressure

Answer: pressure

Answer: mucous membranes

input: OPTIONS:
- magnetism
- sound
- minerals
- energy Now, answer this question: Answer the following question given this paragraph: Conceptual Questions 33.3 Accelerators Create Matter from Energy 1. The total energy in the beam of an accelerator is far greater than the energy of the individual beam particles. Why isn't this total energy available to create a single extremely massive particle? 2. Synchrotron radiation takes energy from an accelerator beam and is related to acceleration. Why would you expect the problem to be more severe for electron accelerators than proton accelerators? 3. What two major limitations prevent us from building high-energy accelerators that are physically small? 4. What are the advantages of colliding-beam accelerators? What are the disadvantages?. Q: Colliding-beam accelerators create matter from what? A:
A:
output:
energy
