1. A food choice equivalent to one serving from the Protein group of MyPlate is:

• A. 1 tbsp peanut butter.
• B. 3 oz fish.
• C. 2 oz cheese.
• D. 1/2 cup cooked dry beans or peas.

Correct answer: A

Rationale: One tablespoon of peanut butter is equivalent to one serving from the Protein group in MyPlate. It provides a good amount of protein and healthy fats. Choices B, C, and D are incorrect as they represent larger serving sizes than a single serving from the Protein group in MyPlate. 3 oz of fish, 2 oz of cheese, and 1/2 cup of cooked dry beans or peas would exceed the recommended serving size for the Protein group.

2. Which of the following are considered micronutrients?

• A. Fats.
• B. Proteins.
• C. Vitamins.
• D. Carbohydrates.

Correct answer: C

Rationale: Micronutrients are essential nutrients needed by the body in small quantities to support various bodily functions. Vitamins fall under this category as they play crucial roles in metabolism, immune function, and overall health. While fats, proteins, and carbohydrates are essential macronutrients required in larger amounts for energy and growth, they are not classified as micronutrients. Therefore, the correct answer is C.

3. The body of scientific knowledge related to nutritional requirements for human growth, maintenance, activity, and reproduction is known as:

• A. physiology.
• B. nutrition science.
• C. biochemistry.
• D. dietetics.

Correct answer: B

Rationale: The correct answer is B: nutrition science. Nutrition science specifically focuses on studying the requirements and functions of nutrients in relation to human growth, maintenance, activity, and reproduction. Choice A, physiology, deals more with the functions of living organisms and their parts, not specifically related to nutrients. Choice C, biochemistry, focuses on the chemical processes and substances that occur within living organisms, not specifically centered on nutritional requirements. Choice D, dietetics, involves the application of nutritional knowledge in planning and managing diets for individuals, but it is more focused on the practical aspect rather than the broader scientific study of nutritional requirements.

4. Which hormone stimulates the gallbladder to contract?

• A. Secretin.
• B. Cholecystokinin (CCK).
• C. Gastrin.
• D. Gastric inhibitory polypeptide (GIP).

Correct answer: B

Rationale: Cholecystokinin (CCK) is the hormone responsible for stimulating the gallbladder to contract and release bile into the small intestine. Secretin primarily acts on the pancreas to stimulate the secretion of bicarbonate-rich fluid. Gastrin functions in the stimulation of gastric acid secretion, while Gastric inhibitory polypeptide (GIP) plays a role in inhibiting gastric acid secretion and stimulating insulin release.

5. What is the preferred fuel for the cells lining the colon?

• A. Short-chain fatty acids.
• B. Long-chain fatty acids.
• C. Amino acids.
• D. Glucose.

Correct answer: A

Rationale: Short-chain fatty acids are the preferred fuel for the cells lining the colon. They provide energy and support gut health by serving as a fuel source for these cells. Long-chain fatty acids are not the preferred fuel for colon cells as they are harder to digest and absorb in this part of the digestive system. Amino acids are the building blocks of proteins and not the primary energy source for colon cells. Glucose is the main energy source for most cells in the body, but colon cells prefer short-chain fatty acids.
