Please answer this: Please answer correctly the following question related to the paragraph below. Where the air would be denser, camp A or camp B? John likes to ride on hot air balloon. Last month he rode on a balloon with his friend Keith. First they were at the ground-level. They called it camp A. Then they rose to the height of three miles. They called it camp B. Eventually, they reached six miles above ground. They called it camp C. Hint: As shown here, pressure decreases to less than 25% of ground-level atmospheric pressure when we get to an altitude of about six miles. Since this is a common cruising altitude for commercial airplanes, pressurized cabins are needed for the comfort and survival of the passengers. This is because the density of the air decreases along with the decreasing air pressure, so there is less oxygen in a breath of air. You've probably noticed this effect in high-mountain areas, as it often feels harder to breath.

Answer: camp A

Please answer this: Please answer correctly the following question related to the paragraph below. Which woman's bread will grow mold slower? Jennifer stores her bread in the cupboard when she gets home from the grocery store since she thinks it tastes better that way. Martha grew up in a household that always kept their bread in the freezer so that's what she does with her bread. Hint: 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. They are more likely to bump into one another and to collide with greater force. For example, when you fry an egg, turning up the heat causes the egg to cook faster. The same principle explains why storing food in a cold refrigerator reduces the rate at which food spoils (see Figure below ). Both food frying and food spoiling are chemical reactions that happen faster at higher temperatures.

Answer: Martha

Please answer this: Please answer correctly the following question related to the paragraph below. Who is more likely to have lowered oxygen supply to their heart muscles? Jake and his son Ryan just had their yearly physical examination by the doctor. As part of this year's examination, both men had their arterial walls examined to identify the presence of plaques. The doctor discovered that Jake had a high amount of plaques present on the interior of his arterial wall. Ryan, on the other hand, had no plaques present. Hint: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death.
