Please answer correctly the following question related to the paragraph below. Does Ryan's left knee have a higher or lower number of neutrophils than his right knee? Ryan is carrying groceries from his car back to his apartment when he trips and falls landing on his knees. Embarrassed, he gets back up, picks up his groceries and carries them into his apartment with his head down. After putting his groceries away, he notices that although both of his knees are scraped, only his left knee is warm to the touch. His right knee feels cool when he puts his hand on it. 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.
Ans: higher

Please answer correctly the following question related to the paragraph below. In wich process heat will be absorbed, process A or process B? John is conducting an experiment in his chemistry lab. His goal is to find a chemical solution that can regulate temperature. To that end, he considered two processes, process A and process B. Process A is an exothermic process, but process B is an endothermic process. Hint: Some materials have negative heats of solution; the dissolution of one of these solutes in water is an exothermic process. Heat is released, causing a net increase in the temperature of the solution. Conversely, other substances have positive heats of solution. For example, the dissolution of potassium nitrate in water is an endothermic process. The resulting absorption of energy causes the solution to become colder. Calculations involving heats of solutions follow the same basic approach that we have used with other enthalpy problems.
Ans: process B

Please answer correctly the following question related to the paragraph below. Who has a higher risk of developing heart disease? Dahlia has smoked cigarettes every day for many years. Dahlia's daughter, Samantha, has never smoked a cigarette in her life. Besides this difference, Dahlia and Samantha have similar activity levels and eat a similar diet. 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:
Ans: Dahlia

Please answer correctly the following question related to the paragraph below. Which continent had less food available to the birds? Two ancient continents both had a great bird population. At some point in time, the continent of MU experienced a great drought that lasted for several years. The other continent, Lemuria, was unaffected by the drought. Hint: A period of very low rainfall occurred while the Grants were on the islands. The drought resulted in fewer seeds for the finches to eat. Birds with smaller beaks could eat only the smaller seeds. Birds with bigger beaks were better off. They could eat seeds of all sizes. Therefore, there was more food available to them. Many of the small-beaked birds died in the drought. More of the big-beaked birds survived and reproduced. Within just a couple of years, the average beak size in the finches increased. This was clearly evolution by natural selection.
Ans: MU
