1. Sucrose is a:

• A. monosaccharide
• B. disaccharide
• C. polysaccharide
• D. starch

Correct answer: B

Rationale: Sucrose is a disaccharide composed of one glucose and one fructose molecule.

2. Which vitamin deficiency is most likely to cause bleeding disorders?

• A. Vitamin A
• B. Vitamin E
• C. Vitamin K
• D. Vitamin D

Correct answer: C

Rationale: Vitamin K is essential for blood clotting as it plays a crucial role in the activation of clotting factors. Deficiency of Vitamin K can lead to impaired blood clotting, resulting in bleeding disorders. Vitamin A is more associated with vision and skin health, not blood clotting. Vitamin E is known for its antioxidant properties and role in immune function, not specifically related to bleeding disorders. Vitamin D plays a key role in calcium absorption and bone health, but it is not directly linked to blood clotting or bleeding disorders.

3. According to the dietary reference intakes, what percentage of your daily calorie intake should ideally come from carbohydrates?

• A. 10-35%
• B. 20-35%
• C. 40-50%
• D. 45-65%

Correct answer: D

Rationale: Carbohydrates should ideally make up 45-65% of your total daily caloric intake, according to the Dietary Reference Intakes (DRIs). This range provides the necessary energy for bodily functions and activities. Choices A, B, and C are incorrect because they fall outside the recommended range for carbohydrate intake based on the DRIs.

4. A caregiver is teaching a parent about recommended protein intake for a toddler. Which of the following food selections is equivalent to 1 oz of protein?

• A. 2 tbsp peanut butter
• B. ½ cup peas
• C. 1 slice of bread
• D. 1 scrambled egg

Correct answer: D

Rationale: One scrambled egg is equivalent to 1 oz of protein, making it a suitable choice for a toddler's diet. A ½ cup of peas (choice B) does not provide 1 oz of protein but is still a good source of protein. 2 tbsp of peanut butter (choice A) contains more than 1 oz of protein. 1 slice of bread (choice C) typically provides less protein than 1 oz.

5. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
