Answer the following question given this paragraph: Like hurricanes, winter storms develop from cyclones. But in the case of winter storms, the cyclones form at higher latitudes. In North America, cyclones often form when the jet stream dips south in the winter. This lets dry polar air pour south. At the same time, warm moist air from the Gulf of Mexico flows north. When the two air masses meet, the differences in temperature and pressure cause strong winds and heavy precipitation. Blizzards and lake-effect snow storms are two types of winter storms that occur in the U. S. Q: Hurricanes and winter storms both develop from what, which often form when the jet stream dips south in the winter? Choices: - tides - waves - typhoons - cyclones A:
cyclones
Answer the following question given this paragraph: Q: What are fibers that depend on aerobic respiration called? Choices: - hydrogen fibers - evaporative fibers - fragile fibers - oxidative fibers A:
oxidative fibers
Q: Answer the following question given this paragraph: Some species of animals are territorial . This means that they defend their area. The area they defend usually contains their nest and enough food for themselves and their offspring. A species is more likely to be territorial if there is not very much food in their area. Animals generally do not defend their territory by fighting. Instead, they are more likely to use display behavior. The behavior tells other animals to stay away. It gets the message across without the need for fighting. Display behavior is generally safer and uses less energy than fighting. Male gorillas use display behavior to defend their territory. They pound on their chests and thump the ground with their hands to warn other male gorillas to keep away from their area. The robin displays his red breast to warn other robins to stay away ( Figure below ). Q: Animals that defend their area are generally known as what kinds of animals? Choices: - mutants - neutral - carnivores - territorial A:
A: territorial
Question: Answer the following question given this paragraph: In measuring quantities we always aim for high accuracy . Estimates that fall within the range of uncertainty for a given instrument are said to be accurate. In our previous example, all of the values between and including 52.4 mL and 53.4 mL would be considered accurate. Estimates that fall outside this range are inaccurate. Accuracy describes how close an estimate is to a known standard. Q: What describes how close an estimate is to a known standard? Choices: - hypothesis - frequency - diversity - accuracy A:
Answer: accuracy

Answer the following question given this paragraph: In 1858, after using microscopes much better than Hooke's first microscope, Rudolf Virchow developed the hypothesis that cells only come from other cells. For example, bacteria, which are single-celled organisms, divide in half (after they grow some) to make new bacteria. In the same way, your body makes new cells by dividing the cells you already have. In all cases, cells only come from cells that have existed before. This idea led to the development of one of the most important theories in biology, the cell theory . Q: Rudolf virchow developed the hypothesis that cells only come from other cells in what year? Choices: - 1898 - 1868 - 1848 - 1858 A:
**Answer**
1858
