[Q]: When studying the kinetic-molecular theory, two teams of students did and experiment. Team A heated a can of soup over the fire without venting it first, team B heated a can of soup, but vented it first. Given the paragraph above, please answer correctly the following question: Which team observed more kinetic energy causing the air molecules to move faster? Hint: It would be very unadvisable to place a can of soup over a campfire without venting the can. As the can heats up, it may explode. The kinetic-molecular theory explains why. The air inside the rigid can of soup is given more kinetic energy by the heat coming from the campfire. The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The increase in pressure inside may eventually exceed the strength of the can and it will explode. An additional factor is that the soup may begin boiling which will then aid even more gas and more pressure to the inside of the can.

input: Please answer the following: Two six graders learned about the lives of animals. Lori learned more about fish, while Dan learned more about mammals. Given the paragraph above, please answer correctly the following question: Which student learned more about gas exchange between the lungs and bloodstream? Hint: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That's about as much surface area as one side of a volleyball court!

Please answer this: While drinking coffee John added some sugar and cream in his coffee. He started to ponder how solutes dissolve in a solvent. To that end, he added solutes in a solvent in six different conditions, case A, case B, case C, case D, case E, and case F. In case A he stirred the solution, but in case B he didn't stir the the solution. In case C he heat the solution up, but in case D he cooled the solution down. In case E he used finely ground solute, but in case F he used cubes of solute. Given the paragraph above, please answer correctly the following question: In which case the solute would have smaller surface area, case E or case F? Hint: When you add sugar to a cold drink, you may stir it to help the sugar dissolve. If you don't stir, the sugar may eventually dissolve, but it will take much longer. Stirring is one of several factors that affect how fast a solute dissolves in a solvent. Temperature is another factor. A solid solute dissolves faster at a higher temperature. For example, sugar dissolves faster in hot tea than in ice tea. A third factor that affects the rate of dissolving is the surface area of the solute. For example, if you put granulated sugar in a glass of ice tea, it will dissolve more quickly than the same amount of sugar in a cube. That's because granulated sugar has much more surface area than a cube of sugar. You can see videos of all three factors at these URLs

Answer: case F
Problem: Robert studied two groups of patients. Group O had mild allergy symptoms, while group R displayed severe allergy symptoms. Given the paragraph above, please answer correctly the following question: Which group experienced itchy eyes? Hint: Allergy symptoms can range from mild to severe. Mild symptoms might include itchy eyes, sneezing, and a runny nose. Severe symptoms can cause difficulty breathing, which may be life threatening. Keep in mind that it is the immune system and not the allergen that causes the allergy symptoms. Allergy symptoms can be treated with medications such as antihistamines. Severe allergic reactions may require an injection of the hormone epinephrine. These treatments lessen or counter the immune system's response.

A: Group O
Problem: Given the question: A team of researchers named Alpha did some research on the inflammatory response in humans for a science contest. A competing team called Omega did research on the human genome. Team Omega lost. Given the paragraph above, please answer correctly the following question: Which team studied more about chemicals that are released when skin or other tissues are damaged? Hint: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue.

The answer is:
Alpha
Problem: The hospital in Y city had a good disposal site in which they disposed of Biomedical wastes, but the hospital in the neighboring city X had big problems, because the biomedical waste contaminated the ground water and affected the population. Given the paragraph above, please answer correctly the following question: Which city had more contaminated ground water? Hint: One of the most adverse impacts of poor waste management, especially municipal waste, is the incidence and prevalence of diseases such as malaria and respiratory problems, as well as other illnesses through the contamination of ground water. Biomedical wastes pose great danger in Bangladesh too as a report estimated that 20% of the biomedical waste is "highly infectious" and is a hazard since it is often disposed of into the sewage system or drains.[6] Such poor sanitation has serious consequences for the health of the residents and a report suggests that "most of the child mortality could be related with this problem".[7] With regards to the living standards, solid waste leads to blockage in the drainage system which leads to flooding in the streets. Consequently, mosquitoes and bad odour are among the negative impacts resulted.[7]

city X
