1. Major nutrients supplied by foods in the Vegetables group of MyPlate include:

• A. potassium and vitamin A.
• B. iron and vitamin C.
• C. calcium and vitamin B12.
• D. sodium and vitamin E.

Correct answer: A

Rationale: The correct answer is A: potassium and vitamin A. Vegetables are an excellent source of potassium and vitamin A, both essential for maintaining overall health. Iron and vitamin C (choice B) are commonly found in foods from the Protein and Fruits groups, respectively. Calcium and vitamin B12 (choice C) are more abundant in dairy products and animal-based foods. Sodium and vitamin E (choice D) are not the major nutrients typically supplied by vegetables.

2. Exchange Lists for Meal Planning group foods that are equivalent in their:

• A. weight.
• B. serving size.
• C. micronutrient content.
• D. macronutrient content.

Correct answer: D

Rationale: The Exchange Lists for Meal Planning categorize foods based on their macronutrient content, such as carbohydrate, protein, and fat. These lists help individuals make food choices while ensuring similar amounts of macronutrients are consumed. Therefore, the correct answer is D. Choices A, B, and C are incorrect because Exchange Lists focus on macronutrient content, not weight, serving size, or micronutrient content.

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. What is necessary for photosynthesis to occur along with carbon dioxide and water?

• A. Glucose.
• B. Nitrogen.
• C. Chlorophyll.
• D. Hydrogen.

Correct answer: C

Rationale: The correct answer is C: Chlorophyll. Chlorophyll is a pigment that is essential for photosynthesis as it absorbs light energy, allowing plants to convert carbon dioxide and water into glucose, a process crucial for plant growth. Glucose (choice A) is produced during photosynthesis and is not an ingredient necessary for the process itself. Nitrogen (choice B) is important for plant growth but is not a direct ingredient for photosynthesis. Hydrogen (choice D) is found in water, which is indeed one of the necessary ingredients for photosynthesis, but chlorophyll is specifically required to capture light energy for the process to occur.

5. What types of muscular movement occur in the intestine?

• A. Longitudinal and circular.
• B. Expulsion and traction.
• C. Tonus and clonus.
• D. Intermittent and continuous.

Correct answer: A

Rationale: The correct answer is A: Longitudinal and circular. Longitudinal and circular muscles are responsible for the movements that help propel food through the intestine. Choice B, expulsion and traction, is incorrect as these terms do not specifically relate to the types of muscular movement in the intestine. Choice C, tonus and clonus, refers to different types of muscle contractions and are not the primary movements in the intestine. Choice D, intermittent and continuous, does not accurately describe the specific types of muscular movement that occur in the intestine.
