Answer the following question given this paragraph: In words, cellular respiration uses oxygen gas to break apart the carbon-hydrogen bonds in glucose and release their energy to build 38 molecules of ATP. Most of this process occurs within the mitochondria of the cell. Carbon dioxide and water are waste products. This is similar to burning, in which oxygen breaks the carbon-hydrogen bonds in a fuel and releases their chemical energy as heat and light. Again, carbon dioxide and water are waste. Q: What uses oxygen gas to break apart the carbon-hydrogen bonds in glucose and release their energy? Choices: - electromagnetic respiration - classical respiration - energetic respiration - cellular respiration A:
cellular respiration
Answer the following question given this paragraph: available; if arsenic is an essential trace mineral in human diets, it is probably required on the order of 50 ppb or less. A toxic dose of arsenic corresponds to about 7,000 ppb and higher, which is over 140 times the trace amount that may be required by the body. Thus, arsenic is not poisonous in and of itself. Rather, it is the amount that is dangerous: the dose makes the poison. Similarly, as much as water is needed to keep us alive, too much of it is also risky to our health. Drinking too much water too fast can lead to a condition called water intoxication, which may be fatal. The danger in water intoxication is not that water itself becomes toxic. It is that the ingestion of too much water too fast dilutes sodium ions, potassium ions, and other salts in the bloodstream to concentrations that are not high enough to support brain, muscle, and heart functions. Military personnel, endurance athletes, and even desert hikers are susceptible to water intoxication if they drink water but do not replenish the salts lost in sweat. As this example shows, even the right substances in the wrong amounts can be dangerous!. Q: Drinking too much water too fast can lead to what potentially fatal condition, which causes dangerous changes to salt levels? Choices: - inebriation - osmosis - drowning - water intoxication A:
water intoxication
Q: Answer the following question given this paragraph: 3.2 | Carbohydrates By the end of this section, you will be able to: Discuss the role of carbohydrates in cells and in the extracellular materials of animals and plants Explain the classifications of carbohydrates List common monosaccharides, disaccharides, and polysaccharides Most people are familiar with carbohydrates, one type of macromolecule, especially when it comes to what we eat. To lose weight, some individuals adhere to "low-carb" diets. Athletes, in contrast, often "carb-load" before important competitions to ensure that they have enough energy to compete at a high level. Carbohydrates are, in fact, an essential part of our diet; grains, fruits, and vegetables are all natural sources of carbohydrates. Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants. Q: Name the simple sugar that is a component of starch. Choices: - Fructose - Splenda - insulin - glucose A:
A: glucose
Question: Answer the following question given this paragraph: A front forms at the boundary between two air masses. Types of fronts include cold, warm, occluded, and stationary fronts. Clouds, precipitation, and storms commonly occur along fronts. Q: What forms at the boundary between two air masses? Choices: - a cool - hurricane - a rough - a front A:
Answer: a front

Answer the following question given this paragraph: Most of us are familiar with rusty iron: metal that has a dark red-brown scale that falls off an object, ultimately weakening it. Although we usually attribute rusting exclusively to iron, this process occurs with many materials. The more formal term for rusting is corrosion. Corrosion is defined as the disintegration of a material due to chemical reactions with other substances in the environment. In many cases, oxygen in the air causes the disintegration. Corrosion is not uniformly destructive. Although the corrosion of iron is generally considered bad, the corrosion of aluminum and copper forms a protective barrier on the surface of the metal, protecting it from further reaction with the environment. Having said that, it has been estimated that as much as 5% of expenditures in the United States apply to fixing problems caused by corrosion. The replacement of structures built with iron, steel, aluminum, and concrete must be performed regularly to keep these structures safe. As an example of what might happen, consider the story of the Silver Bridge on US Interstate 35, connecting West Virginia and Ohio. On December 15, 1967, the 39-year-old bridge collapsed, killing 46 people. The ultimate cause of the collapse was determined to be corrosion of a suspension chain on the Ohio side of the bridge. Corrosion is an example of the type of chemical reaction discussed in this chapter. Although we usually think of corrosion as bad, the reaction it typifies can actually be put to good use. One important type of chemical reaction is the oxidation-reduction reaction, also known as the redox reaction. Although we introduced redox reactions in - ball-ch04, - ball-ch04_s06, it is worth reviewing some basic concepts. Q: Exemplified by rusty iron, what process is defined as the disintegration of a material due to chemical reactions with other substances in the environment? Choices: - Metal Breakdown - magnesium - extraction - corrosion A:
**Answer**
corrosion
Answer the following question given this paragraph: Most fungi are decomposers. They are the main decomposers in forests. Many fungi have symbiotic relationships with other species. Q: What organism is responsible for most decomposition in forest? Choices: - coral - bacteria - yeast - fungi A:
fungi
