Ques: Answer the following question given this paragraph: Encephalitis is a brain infection ( Figure below ). If you have encephalitis, you are likely to have a fever and headache or feel drowsy and confused. The disease is most often caused by viruses. The immune system tries to fight off a brain infection, just as it tries to fight off other infections. But sometimes this can do more harm than good. The immune system's response may cause swelling in the brain. With no room to expand, the brain pushes against the skull. This may injure the brain and even cause death. Medicines can help fight some viral infections of the brain, but not all infections. Q: What body part does encephalitis attack? Choices: - lungs - liver - heart - brain A:
Ans: brain

Q: What does cartilage lack compared to bones, making it softer and less rigid? Choices: - potassium - magnesium - protein - calcium A:
Ans: calcium

Ques: Answer the following question given this paragraph: Disaccharides A disaccharide is a pair of monosaccharides. Disaccharides are formed via dehydration synthesis, and the bond linking them is referred to as a glycosidic bond (glyco- = "sugar"). Three disaccharides (shown in Figure 2.19) are important to humans. These are sucrose, commonly referred to as table sugar; lactose, or milk sugar; and maltose, or malt sugar. As you can tell from their common names, you consume these in your diet; however, your body cannot use them directly. Instead, in the digestive tract, they are split into their component monosaccharides via hydrolysis. Q: A disaccharide is a pair of monosaccharides. disaccharides are formed via dehydration synthesis, and the bond linking them is referred to as a glycosidic bond (glyco- = "sugar"). three disaccharides (shown in figure 2.19) are important to humans. these are sucrose, commonly referred to as table sugar; lactose, or milk sugar; and maltose, or this? Choices: - fruit sugar - saccharin - sucralose - malt sugar A:
Ans: malt sugar

Ques: Answer the following question given this paragraph: Gases in the coma and tail of a comet reflect light from the Sun. Comets are very hard to see except when they have comas and tails. That is why they appear only when they are near the Sun. They disappear again as they move back to the outer solar system. Q: What parts of comets make them easy to see? Choices: - arcs and tails - novas and tails - craters and tails - comas and tails A:
Ans:
comas and tails
