Q: Please answer correctly the following question related to the paragraph below. Which student read more about the second part of the small intestine? Pete liked the human physiology so he started reading about the digestive system, especially about the jejunum. His colleague Fox, studied more about the stomach. Hint: The jejunum is the second part of the small intestine, where most nutrients are absorbed into the blood. As shown in Figure below , the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries. Because there are so many villi, they greatly increase the surface area for absorption. In fact, they make the inner surface of the small intestine as large as a tennis court!
A: Pete

Q: Please answer correctly the following question related to the paragraph below. Given the new liquid is already in vapor form, will cooling the vapor below 50 degrees cause it to evaporate or return it to a liquid state? A new liquid is found with a boiling point of 50 degrees C. John poured some of this liquid in a pot and began heating it to 60 degrees. Eventually all of the liquid vaporizes Hint: As a liquid is heated, the average kinetic energy of its particles increases. The rate of evaporation increases as more and more molecules are able to escape the liquid's surface into the vapor phase. Eventually a point is reached when the molecules all throughout the liquid have enough kinetic energy to vaporize . At this point the liquid begins to boil. The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure. The Figure below illustrates the boiling of liquid.
A: liquid state

Q: Please answer correctly the following question related to the paragraph below. Which patient would not have inflammation of retina, patient A or patient B? Local hospital has launched a program to check if a patient has Retinitis. Resident ophthalmologist David is in charge of this program. In the first day of the program he checked two patients, patient A and patient B. The test result showed that patient A had Retinitis, but patient B did not have Retinitis. Then next day David checked two other patients, patient C and patient D. Patient C was 40 years old, but patient D was 80 years old. He found both patient C and D had Retinitis. Hint: Retinitis is inflammation of the retina in the eye, which can permanently damage the retina and lead to blindness. The retina is the part of your eye that is also known as the "sensing tissue." Retinitis may be caused by a number of different infectious agents. Retinitis, also called Retinitis pigmentosa, has a prevalence of one in every 2,500-7,000 people. This condition is one of the leading causes that leads to blindness in patients in the age range of 2060 years old.
A: patient B

Q: Please answer correctly the following question related to the paragraph below. Will the volume of the air in the balloon increase or decrease when more pressure is applied to it? Cindy is throwing a party. One of the games she decides to have is a balloon popping competition. In which people will try to pop as many balloons as they can and will win a prize. Her friend George pops the balloons by picking them up and squeezing. Her friend Meredith quickly grabs a balloon and throws her entire weight on it to quickly pop it. Hint: What does popping bubble wrap have to do with science? Actually, it demonstrates an important scientific law, called Boyle's law. Like other laws in science, this law describes what always happens under certain conditions. Boyle's law is one of three well-known gas laws, which state the relationships among temperature, volume, and pressure of gases. (The other two gas laws are Charles' law and Amontons' law.) According to Boyle's law , if the temperature of a gas is held constant, then decreasing the volume of the gas increases its pressureand vice versa. That's what happens when you squeeze the bubbles of bubble wrap. You decrease the bubbles' volume, so the air pressure inside the bubbles increases until they pop.
A:
decrease
