Q: I read this background article the other day: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage. I am facing a new situation today: A scientist is observing two chemicals react. The reaction is very slow and he wants to find a way to speed up the reaction. One day the labs air conditioner breaks and he notices the reaction is happening significantly faster than usual. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will increasing the temperature of the chemicals increase or decrease the speed of the reaction?
A: increase
Question: I read this background article the other day: Current Situation : Currently the heating effect of extra greenhouse gases (since the start of the industrial revolution) is equal to about . Thus the recent period has recorded parallel increases in concentration of carbon dioxide and average global temperature. As more greenhouse gases are put into the atmosphere the temperature will increase further. There are certain effects of a warmer Earth (discussed more in optional section), which could accelerate the process, even if no more greenhouse gases are put into the atmosphere (an unlikely prospect for the foreseeable future). I am facing a new situation today: A group of researches studied the green house gas emissions and their effects on Earth and people during the eighties compared to the twenties. The eighties produced way more green house gasses than the twenties did. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which decade recorded parallel increases in concentration of carbon dioxide and average global temperature?
Answer: eighties
[Q]: I read this background article the other day: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. I am facing a new situation today: Angela just bent through a really bad breakup and is feeling very depressed. To make herself feel better she tends to binge on foods that happen to be very high in lipids. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will a high fat diet increase or decrease lipid levels in the blood?
****
[A]: increase
input: Please answer the following: I read this background article the other day: 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. I am facing a new situation today: Jerry and George are two roommates who have lived together since college. They have always gotten along well, have similar hobbies and even are the same height. They both enjoy watching sports and playing videogames, but Jerry also rides his bike several miles each week. George can't stand exercising. Instead, he prefers to lay around relaxing and driving his car if he needs to go somewhere. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is less likely to become obese?
++++++++++
output: Jerry
Please answer this: I read this background article the other day: Another example of incomplete dominance is with sickle cell anemia, a disease in which a blood protein called hemoglobin is produced incorrectly. This causes the red blood cells to have a sickle shape, making it difficult for these misshapen cells to pass through the smallest blood vessels. A person that is homozygous recessive ( ss ) for the sickle cell trait will have red blood cells that all have the incorrect hemoglobin. A person who is homozygous dominant ( SS ) will have normal red blood cells. I am facing a new situation today: Trisha has a doctors appointment to get some blood work done. She goes to see her doctor and he takes a blood sample. Sadly when he comes back he reports to her that her blood cells are misshapen and look like small sickles, as well as her hemoglobin is being produced incorrectly. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will a person with sickle cell anemia have circular red blood cells or red blood cells shaped like sickles?
++++++++
Answer: sickles
Question: I read this background article the other day: 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. I am facing a new situation today: Bill and Chad both displayed allergic reactions. Bill's were mild symptoms, while Chad's were more severe allergic reactions and was rushed to the hospital. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person's allergies could be treated with epinephrine?
Answer:
Chad's
