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. A chemical feature that distinguishes a saturated fatty acid from an unsaturated fatty acid is the:
- A. arrangement of carbon atoms.
- B. number of oxygen molecules.
- C. number of double bonds.
- D. food source.
Correct answer: C
Rationale: The correct answer is C. Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds. Therefore, the number of double bonds is the chemical feature that distinguishes a saturated fatty acid from an unsaturated fatty acid. Choices A, B, and D are incorrect because the distinguishing factor between saturated and unsaturated fatty acids lies in the presence or absence of double bonds, not in the arrangement of carbon atoms, number of oxygen molecules, or food source.
3. A physical science that contributes to understanding how nutrition relates to health and well-being is:
- A. anatomy
- B. biochemistry
- C. physics
- D. pharmacology
Correct answer: B
Rationale: Biochemistry is the correct answer because it focuses on understanding the chemical processes related to nutrition and how nutrients affect the body. Anatomy (choice A) primarily deals with the structure of organisms, not the chemical processes of nutrition. Physics (choice C) deals with energy and matter, not specifically related to nutrition. Pharmacology (choice D) focuses on drugs and their interactions with the body, not directly related to nutrition and its effects on health.
4. The valve that controls the passage of chyme from the small intestine into the cecum is called the:
- A. ileocecal valve.
- B. pyloric valve.
- C. cardiac valve.
- D. hepatic valve.
Correct answer: A
Rationale: The correct answer is A: ileocecal valve. The ileocecal valve is located between the small intestine and the cecum, controlling the passage of chyme. The pyloric valve (choice B) is located between the stomach and the small intestine, regulating the passage of food from the stomach to the small intestine. The cardiac valve (choice C) refers to the valve between the esophagus and the stomach. The hepatic valve (choice D) is not a correct term related to the passage of chyme from the small intestine into the cecum.
5. Which term describes the amino acids that are synthesized by the body?
- A. essential amino acids.
- B. nonessential amino acids.
- C. complete amino acids.
- D. incomplete amino acids.
Correct answer: B
Rationale: The correct answer is B: nonessential amino acids. Nonessential amino acids can be synthesized by the body, so they do not need to be obtained through the diet. Essential amino acids, choice A, must be obtained from the diet because the body cannot produce them. Choices C and D, complete and incomplete amino acids respectively, do not accurately describe the classification of amino acids based on synthesis by the body.
