What is the process by which bone is broken down and then rebuilt called?

A. “None of the above” is incorrect because the correct range for carbohydrate intake is listed among the options.

B. The range of 10 to 35 percent corresponds to protein intake, not carbohydrates.

C. The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates for young adults (ages 19 to 30) is 45 to 65 percent of total daily calories. This range ensures adequate energy for daily activities, supports proper brain function, and provides dietary fiber for digestive health. Carbohydrates are the body’s primary energy source, and maintaining intake within this range helps prevent both nutrient deficiencies and excessive weight gain.

D. The range of 20 to 35 percent corresponds to fat intake, not carbohydrates.

A. Traditional methods of food preservation—salting, sugaring, drying, and smoking—have been used for centuries and remain in use today. Salting draws moisture out of foods to inhibit bacterial growth. Sugaring, used in jams and candies, reduces water activity, making the environment unsuitable for microbes. Drying removes moisture, preventing spoilage, while smoking imparts flavor and introduces compounds that inhibit microbial growth. These methods were developed long before modern technology and continue to be effective, particularly in artisanal and emergency food preservation.

B. Stabilizers, texturizers, and emulsifiers are modern food additives used to improve texture, consistency, and appearance in processed foods, not traditional preservation methods.

C. Preservatives such as vitamin C (ascorbic acid) and vitamin E (tocopherols) are modern chemical methods to prevent oxidation and spoilage, and were not historically used prior to technological advances.

D. Mechanical refrigeration is a technological advancement that emerged in the 19th and 20th centuries. While highly effective, it is not considered a traditional method of food preservation.
