Problem: Please answer correctly the following question related to the paragraph below. Which student studied species that play an important role in an ecosystem? Two students from the same class, studies different types of animals. Bill studied predators, while John studied grazers. Hint: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species.

A: Bill
Problem: Given the question: Please answer correctly the following question related to the paragraph below. Will Zandonia's population becoming even greater cause the demand for natural resources to increase or decrease? A new country called Zandonia has recently found itself in a crisis. They are consuming far to many natural resources. A recent study concluded that the amount of resources being consumed greatly increased over the past 3 years. This find coincides with a population boom in the region. Before the population boom the demand for natural recources was relatively stable. Hint: Population growth, especially in developing countries, should make people think about how fast they are consuming resources. Governments around the world should seriously consider these issues. Developing nations will also increase demands on natural resources as they build more factories ( Figure below ). Improvements in technology, conservation of resources, and controls in population growth could all help to decrease the demand on natural resources.

The answer is:
decrease
input question: Please answer correctly the following question related to the paragraph below. Will a precocial animal require more care or less care from it's parents? Mary's dog just gave birth to a litter of puppies! As of right now the puppies eyes are closed so they can't see. They require the mother to take very close care of them while they grow to keep them safe. Hint: Organisms can use different strategies to increase their reproduction rate. Altricial organisms are helpless at birth, and their parents give them a lot of care. This care is often seen in bird species. ( Figure below ). Altricial birds are usually born blind and without feathers. Compared to precocial organisms, altricial organisms have a longer period of development before they reach maturity. Precocial organisms, such as the geese shown below, can take care of themselves at birth and do not require help from their parents ( Figure below ). In order to reproduce as much as possible, altricial and precocial organisms must use very different strategies.???

Please answer correctly the following question related to the paragraph below. Which brother didn't get a type of roundworm parasite? Two brothers had very bad luck when they attended a wedding. Tom fell violently ill after eating some tainted food, and he was rushed to the hospital. His brother Rob felt sick later, after eating the main course. Tom was infected with norovirus and hepatitis A, while Rob was infected with Giardia and Trichinella. Hint: Common foodborne viruses include norovirus and hepatitis A virus. Norovirus, which causes inflammation of the stomach and intestines, has been a recent issue on cruise ships, infecting hundreds of passengers and crew on certain voyages. Hepatitis A causes inflammation of the liver, which is treated with rest and diet changes. Parasites are tiny organisms that live inside another organism. Giardia is a parasite spread through water contaminated with the stools of people or animals who are infected. Food preparers who are infected with parasites can also contaminate food if they do not thoroughly wash their hands after using the bathroom and before handling food. Trichinella is a type of roundworm parasite. People may be infected with this parasite by consuming raw or undercooked pork or wild game.

Q: Please answer correctly the following question related to the paragraph below. At which point the horn would sound lower in pitch, point D or point E? John was sitting at point C near a railway track. Suddenly, he heard a train coming towards him from point A with constant sound of its horn. Eventually, it reached very close to him at point B. Then the train sped by him at point C where he was sitting, reaching point D after some time. Finally, it reached even farther from him at point E. Hint: Look at the police car in Figure below . The sound waves from its siren travel outward in all directions. Because the car is racing forward (toward the right), the sound waves get bunched up in front of the car and spread out behind it. As the car approaches the person on the right (position B), the sound waves get closer and closer together. In other words, they have a higher frequency. This makes the siren sound higher in pitch. After the car speeds by the person on the left (position A), the sound waves get more and more spread out, so they have a lower frequency. This makes the siren sound lower in pitch. A change in the frequency of sound waves, relative to a stationary listener, when the source of the sound waves is moving is called the Doppler effect . You've probably experienced the Doppler effect yourself. The next time a vehicle with a siren races by, listen for the change in pitch. For an online animation of the Doppler effect, go to the URL below.

[Q]: Please answer correctly the following question related to the paragraph below. Which sister had an inflammation of the intestines? Two sisters attended a wedding. Ann got very sick early on, after eating the appetizer. She was infected with norovirus and with hepatitis A. Bianca danced for a while then ate the main course and fell ill. She found out she was infected with Giardia and trichinella. Hint: Common foodborne viruses include norovirus and hepatitis A virus. Norovirus, which causes inflammation of the stomach and intestines, has been a recent issue on cruise ships, infecting hundreds of passengers and crew on certain voyages. Hepatitis A causes inflammation of the liver, which is treated with rest and diet changes. Parasites are tiny organisms that live inside another organism. Giardia is a parasite spread through water contaminated with the stools of people or animals who are infected.
