Problem: Given the question: I can use this background: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks. Now, I have a new situation: Two different islands had animals evolving in different ways. Big island had new species develop naturally through natural selection, while Low island did not. Answer this question please: Which island didn't experience natural selection?

The answer is:
Low
input question: I can use this background: The quantity of small plastic fragments floating in the north-east Pacific Ocean increased a hundredfold between 1972 and 2012.Marine pollution is a generic term for the harmful entry into the ocean of chemicals or particles. The main culprits are those using the rivers for disposing of their waste. The rivers then empty into the ocean, often also bringing chemicals used as fertilizers in agriculture. The excess of oxygen-depleting chemicals in the water leads to hypoxia and the creation of a dead zone.Marine debris, also known as marine litter, is human-created waste that has ended up floating in a lake, sea, ocean, or waterway. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter.In addition, the Pacific Ocean has served as the crash site of satellites, including Mars 96, Fobos-Grunt, and Upper Atmosphere Research Satellite. Now, I have a new situation: Two old friends were both oceanographers. They were both researching the levels of marine pollution in Earth's oceans. Vic studied the Arctic Ocean, while Dan studied the Pacific Ocean. Answer this question please: Which friend observed more fertilizers which cause marine pollution ????
output answer: Dan
I can use this background: Another example of negative feedback has to do with blood glucose levels. When glucose (sugar) levels in the blood are too high, the pancreas secretes insulin to stimulate the absorption of glucose and the conversion of glucose into glycogen, which is stored in the liver. As blood glucose levels decrease, less insulin is produced. When glucose levels are too low, another hormone called glucagon is produced, which causes the liver to convert glycogen back to glucose. Now, I have a new situation: A doctor named Phil is researching how sugar affects the body. He noted when his participants ate a lot of sugar their livers would produce a lot more insulin than usual. The insulin would convert the sugar into glycogen. When they had a normal amount of sugar the amount of insulin was stable. He then had a person not eat at all and he found another hormone called glucagon was being produced. This hormone was converting the glycogen back into glucose, also known as sugar. Answer this question please: Will not eating for a long period of time cause glycogen levels to increase or decrease?

Answer: increase
Q: I can use this background: In addition to insects, weeds have also been a menace to farmers - just ask anyone with a garden how much they hate weeds. They can quickly compete for water and nutrients needed by other plants. Sure, farmers can use herbicides to kill weeds, but do these chemicals also harm the crops? Can biotechnology help with this issue? Some crops have also been genetically engineered to acquire tolerance to the herbicides - allowing the crops to grow, but killing the weeds. But the lack of cost effective herbicides with a broad range of activity - that do not harm crops - is a problem in weed management. Multiple applications of numerous herbicides are routinely needed to control the wide range of weeds that are harmful to crops. And at times these herbicides are being used as a preventive measure that is, spraying to prevent weeds from developing rather than spraying after weeds form. So these chemicals are being added to crops. This practice is followed by mechanical and/or hand weeding to control weeds that are not controlled by the chemicals. Crops that are tolerant of herbicides would obviously be a tremendous benefit to farmers ( Figure above ). The introduction of herbicide tolerant crops has the potential to reduce the number of chemicals needed during a growing season, thereby increasing crop yield due to improved weed management and decreased harm to the crops. Now, I have a new situation: Jamie decided he wants to build a garden in his back yard. He finishes planting a nice crop of tomatoes and zucchini and is very happy with himself. About a month later he checks in on his garden only to see a plethora of weeds has grown with his crop. The tomato and zucchini plants are much smaller than he expected and some are even dying. Answer this question please: Given Jamie removes all the weeds in his garden, will his plants get more or less nutrients and water?
A: more
Question: I can use this background: A major use for petroleum products is fuel for cars, trucks, airplanes, trains, and other vehicles. The chemical used are usually a mixture of compounds containing several carbon atoms in a chain. When the material is ignited, a massive amount of gas is created almost instantaneously. This increase in volume will move the pistons in an internal combustion engine to provide power. A jet plane works on a similar principle. Air comes into the front of the engine and mixes with the jet fuel. This mixture is ignited and the gases formed create a lot of pressure to push the plane forward. The idea can be seen even more clearly in the case of a rocket launch. The ignition of the fuel (either solid-state or liquid) creates gases produced under great pressure that pushes the rocket up. Now, I have a new situation: Company A was a refinery and managed petroleum products. Another company, named company H, produced and distributed electricity using wind power. Both companies strive to be more efficient and to pollute less. Answer this question please: Which company made a mixture of compounds containing several carbon atoms in a chain?
Answer: Company A
Please answer this: I can use this background: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. Now, I have a new situation: John is a physician in the local hospital. Today, he is seeing two patients, patient A and patient B. John determines that patient A is obese, and patient B is not obese. He needs to prescribe medicine according to his findings. Answer this question please: Would patient A be more or less at risk for developing type 2 diabetes than patient B?
