Answer the following question given this paragraph: Water can remain in a particular location for a long time. This is known as a reservoir . Reservoirs for water include oceans, glaciers, ponds, or even the atmosphere. A water molecule may pass through a reservoir very quickly or may remain for much longer. The amount of time a molecule stays in a reservoir is known as its residence time . The residence time of water in the ocean is 3,200 years. Of course, not every molecule stays that long. That number is an average for all molecules. Q: What is the amount of time a molecule stays in a reservoir known as? Choices: - known time - reservoir time - suitable time - residence time A:
(Answer)
residence time
Ques: Answer the following question given this paragraph: The nuclei of radioisotopes are unstable, so they constantly decay and emit radiation. Q: The nuclei of radioisotopes are unstable, so they constantly decay and emit what? Choices: - moisture - acid - chemicals - radiation A:
Ans: radiation
(Q).
Answer the following question given this paragraph: To allow the plant to retain water and exchange gases, small pores (holes) in the leaves called stomata also evolved ( Figure below ). The stomata can open and close depending on weather conditions. When it's hot and dry, the stomata close to keep water inside of the plant. When the weather cools down, the stomata can open again to let carbon dioxide in and oxygen out. Q: What is the name for the pores in leaves that allow a plant to retain water or exchange gases? Choices: - neurons - chloroplasts - rhizomes - stomata A:
(A).
stomata
Ques:Answer the following question given this paragraph: Resistance is opposition to the flow of electric charges that occurs when electric current travels through matter. The SI unit of resistance is the ohm (named for the scientist Georg Ohm, whom you can read about below). Resistance is caused by electrons in a current bumping into electrons and ions in the matter through which the current is flowing. Resistance is similar to the friction that resists the movement of one surface as it slides over another. Resistance reduces the amount of current that can travel through the material because some of the electrical energy is converted to other forms of energy. For example, when electric current flows through the tungsten wire inside an incandescent light bulb, the tungsten resists the flow of electric charge, and some of the electrical energy is converted to light and thermal energy. Q: What term means opposition to the flow of electric charges that occurs when electric current travels through matter? Choices: - polarity - antagonism - diffusion - resistance A:

Ans:resistance
Ques: Answer the following question given this paragraph: The two smallest carboxylic acids are formic acid (found in the stingers of ants) and acetic acid (found in vinegar). Many organic compounds are considerably more complex than the examples described here. Many compounds, such as cholesterol discussed in the chapter-opening essay, contain more than one functional group. The formal names can also be quite complex. In http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gobch12through http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch15, we will examine the characteristics and chemistry of other important organic compounds and functional groups. Q: The two smallest carboxylic acids are formic acid and what else? Choices: - carbonates acid - ethylene acid - ascorbic acid - acetic acid A:
Ans:
acetic acid
