Answer the following question given this paragraph: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U. S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf. Q: Rain dissolves fertilizer in the soil, what carries it away? Choices: - carbon ? - fossils - clouds - runoff? A:
runoff?
Q: Answer the following question given this paragraph: Viruses were first described by Dmitri Ivanovsky in 1892. He described a "non-bacterial pathogen" infecting tobacco plants. This was soon followed by the identification of the tobacco mosaic virus by Martinus Beijerinck in 1898. Since then, about 5,000 viruses have been described in detail, although it is believed that there are millions of different types. Viruses are found in almost every ecosystem on Earth, and are the most abundant type of biological entity. Viruses can be classified with a taxonomic structure from order to species. No kingdom classification exists. Viruses, not being made of cells, do not fall into any of the six prokaryotic or eukaryotic kingdoms. Q: What is the most abundant type of biological entity on the earth? Choices: - bacteria - reptiles - insects - viruses A:
A: viruses
Question: Answer the following question given this paragraph: All alkali metals are very soft and can be cut easily with a knife. Due to their high reactivity, they must be stored under oil to prevent them from reacting with oxygen or water vapor in the air. The reactions between alkali metals and water are particularly vigorous and include the rapid production of large quantities of hydrogen gas. Alkali metals also react easily with most nonmetals. All of the alkali metals are far too reactive to be found in nature in their pure elemental form. For example, all naturally occurring sodium exists as a compound, such as sodium chloride (table salt). Q: The reactions between alkali metals and water are particularly vigorous and include the rapid production of large quantities of what gas? Choices: - helium - oxygen - carbon - hydrogen A:
Answer: hydrogen
