Question: Scientists studied water stratification in two saltwater lakes. they were trying to find out why the fish population decreased in Long lake, and was very healthy and abundant in Shoal lake. They found out the phenomenon occurred more often in Long lake, leading to very many unpleasant chain effects. Given the paragraph above, please answer correctly the following question: Which lake had a smaller fish population? Hint: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers. Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2]
Answer: Long lake
[Q]: 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. Given the paragraph above, please answer correctly the following question: Which sister didn't have a type of roundworm? 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.

input: Please answer the following: David collects cigarette packs of different years. He found that two of his packs, pack A and pack B, are very different. Pack A is from before September 2012, and pack B is from after September 2012. He started searching on the internet to find out why the packs were different. Given the paragraph above, please answer correctly the following question: Would pack B induce less or more awareness of smoking health risks than pack A? Hint: Beginning in September 2012, the U.S. Food and Drug Administration will require larger, more prominent cigarette health warnings on all cigarette packaging and advertisements in the United States. These warnings are a significant advancement in communicating the dangers of smoking. These new cigarette health warnings contains nine different warnings that will increase awareness of the specific health risks associated with smoking, such as death, addiction, lung disease, cancer, stroke and heart disease. These warnings include:

Please answer this: David is experimenting with electromagnetic waves. He has four different waves to study, wave A, wave B, wave C, and wave D. In wave A, distance between two corresponding points on adjacent waves is greater than that of wave B. In wave C, the number of waves that pass a fixed point in a given time is greater than that of wave D. Given the paragraph above, please answer correctly the following question: Would wave B have less or more energy than wave A? Hint: Electromagnetic radiation is energy that travels in waves across space as well as through matter. Most of the electromagnetic radiation on Earth comes from the sun. Like other waves, electromagnetic waves are characterized by certain wavelengths and wave frequencies. Wavelength is the distance between two corresponding points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. Electromagnetic waves with shorter wavelengths have higher frequencies and more energy.

Problem: Two students read about brains in the animal kingdom. Tom read more about the brains of mammals, while Reed learned more about the brains of amphibians. Given the paragraph above, please answer correctly the following question: Which student learned more about the human neocortex? Hint: The brains of all mammals have a unique layer of nerve cells covering the cerebrum. This layer is called the neocortex (the pink region of the brains in Figure above ). The neocortex plays an important role in many complex brain functions. In some mammals, such as rats, the neocortex is relatively smooth. In other mammals, especially humans, the neocortex has many folds. The folds increase the surface area of the neocortex. The larger this area is, the greater the mental abilities of an animal.

input: Please answer the following: San Francisco and Baltimore both have large manufacturing and production industries and both border large oceans. San Francisco has been burning large amounts of fossil fuels recently to fuel their increased manufacturing and production of automobiles. Baltimore, however, has shifted to renewable resources recently, and as a result they have drastically decreased the amount of fossil fuels that are used to produce and manufacture steel. Given the paragraph above, please answer correctly the following question: Oceans bordering which city, San Francisco or Baltimore, will have less dead corals and shellfish? Hint: Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic. Burning fossil fuels has led to an increase in carbon dioxide in the atmosphere. This carbon dioxide is then absorbed by the oceans, which lowers the pH of the water. Ocean acidification can kill corals and shellfish. It may also cause marine organisms to reproduce less, which could harm other organisms in the food chain. As a result, there also may be fewer marine organisms for humans to consume.
