1. Food energy is commonly expressed in kilocalories and in what other unit?

• A. kilojoules
• B. kilograms
• C. kilometers
• D. kilonewtons

Correct answer: A

Rationale: Food energy is commonly expressed in kilocalories and kilojoules. Kilocalories and kilojoules are both units of energy commonly used to measure the energy content of food. Kilograms, kilometers, and kilonewtons are units of mass, distance, and force, respectively, and are not used to express food energy.

2. Which of the following is considered a micronutrient?

• A. Protein
• B. Carbohydrate
• C. Vitamin C
• D. Fat

Correct answer: C

Rationale: Corrected Question: Vitamin C is considered a micronutrient because it is required in small amounts for proper body functioning and is essential for health. Proteins, carbohydrates, and fats are macronutrients, needed in larger quantities for energy and other body functions. Vitamin C, being a micronutrient, plays a crucial role in various bodily functions even though it is needed in smaller quantities compared to macronutrients. Therefore, the correct answer is C. Choice A (Protein), Choice B (Carbohydrate), and Choice D (Fat) are incorrect as they are macronutrients required in larger amounts for energy and other body functions.

3. Which nutrient is classified as a micronutrient?

• A. minerals
• B. proteins
• C. alcohols
• D. carbohydrates

Correct answer: A

Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.

4. When an increase in exercise is accompanied by a decrease in body weight, it is an example of what?

• A. variable effect
• B. positive correlation
• C. negative correlation
• D. randomization effect

Correct answer: C

Rationale: When an increase in exercise is accompanied by a decrease in body weight, it demonstrates a negative correlation. This means that as one variable (exercise) increases, the other variable (body weight) decreases. Choice A, 'variable effect,' is vague and does not accurately describe the relationship between exercise and body weight. Choice B, 'positive correlation,' is incorrect because in a positive correlation, both variables would increase or decrease together. Choice D, 'randomization effect,' is unrelated to the scenario described.

5. Which statement is true of minerals in their role as nutrients?

• A. They are organic compounds.
• B. They yield 4 kilocalories per gram.
• C. Some become dissolved in body fluids.
• D. Some are destroyed during cooking.

Correct answer: C

Rationale: The correct statement is that some minerals become dissolved in body fluids, making them available for absorption and utilization by the body. Minerals are not organic compounds, so choice A is incorrect. Choice B is incorrect because minerals do not provide energy like macronutrients such as carbohydrates and fats. Choice D is incorrect because minerals are elements and cannot be destroyed by cooking; however, their availability and absorption may be affected by cooking methods.
