Answer to Question 1

C

Answer to Question 2

D
Because lipids provide more energy per gram than any other nutrient (lipids provide 9 kcals per gram; protein and carbohydrate provide 4 kcals per gram and alcohol provides 7 kcals per gram), they are the best source of dense energy for the body. They do provide some body-building ma-terials: phospholipids are an important part of the structure of cell membranes. However proteins and minerals probably contribute more than lipids to building body structure. Lipids cannot be converted to glucose in the body.

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
