Answer the following question given this paragraph: The water Americans get from their faucets is safe. This water has been treated and purified. At least 20% of the world's people do not have clean drinking water always available. That's more than 1 billion people. They must drink water from where they can get it. Maybe straight from a river or pond ( Figure below ). Human wastes may be in the water. If that's the case, the water will probably contain pathogens. Pathogens are organisms that cause diseases. Q: At least 20 percent of the world's people do not have a ready supply of what? Choices: - clothing - food - oil - clean drinking water A:
(Answer)
clean drinking water
Ques: Answer the following question given this paragraph: Connections of Other Sugars to Glucose Metabolism Glycogen, a polymer of glucose, is an energy storage molecule in animals. When there is adequate ATP present, excess glucose is shunted into glycogen for storage. Glycogen is made and stored in both liver and muscle. The glycogen will be hydrolyzed into glucose monomers (G-1-P) if blood sugar levels drop. The presence of glycogen as a source of glucose allows ATP to be produced for a longer period of time during exercise. Glycogen is broken down into G-1-P and converted into G-6-P in both muscle and liver cells, and this product enters the glycolytic pathway. Q: Where is glycogen created and stored in the body? Choices: - extracts and muscles - Healing Muscles - Sore muscle - liver and muscles A:
Ans: liver and muscles

Answer the following question given this paragraph: The electrical potential difference between the two plates is expressed as , the electric field strength times the distance between the plates. The units in this expression are Newtons/coulomb times meters, which gives the final units Joules/coulomb. Voltage is an expression of the amount of potential energy per unit charge. The work done moving a charge against the field can be calculated by multiplying the electric field potential by the charge, . Q: What is it called when a charge moves against a field? Choices: - momentum - power - force - work A:
(A).
work
Ques:Answer the following question given this paragraph: The direct conversion of a solid to a gas, without an intervening liquid phase, is calledsublimation. The amount of energy required to sublime 1 mol of a pure solid is theenthalpy of sublimation (Hsub). Common substances that sublime at standard temperature and pressure (STP; 0C, 1 atm) include CO2 (dry ice); iodine (Figure 11.18 "The Sublimation of Solid Iodine"); naphthalene, a substance used to protect woolen clothing against moths; and 1,4-dichlorobenzene. As shown in Figure 11.17 "The Three Phases of Matter and the Processes That Interconvert Them When the Temperature Is Changed", the enthalpy of sublimation of a substance is the sum of its enthalpies of fusion and vaporization provided all values are at the same T; this is an application of Hess's law. (For more information about Hess's law, see Chapter 5 "Energy Changes in Chemical Reactions", Section 5.2 "Enthalpy"). Equation 11.3. Q: The direct conversion of a solid to a gas, without an intervening liquid phase, is called what? Choices: - amplification - isolation - insertion - sublimation A:

Ans:sublimation
Question: Answer the following question given this paragraph: The concentration of hydronium ions in a solution is known as acidity . In pure water, the concentration of hydronium ions is very low; only about 1 in 10 million water molecules naturally breaks down to form a hydronium ion. As a result, pure water is essentially neutral. Acidity is measured on a scale called pH , as shown in Figure below . Pure water has a pH of 7, so the point of neutrality on the pH scale is 7. Q: The concentration of hydronium ions in a solution is known as what? Choices: - base - akaline - pH value - acidity A:
Answer:
acidity
