1. A vegetarian diet that includes dairy foods and eggs is known as:

• A. lactovegetarian.
• B. vegan.
• C. semi-vegetarian.
• D. ovolactovegetarian.

Correct answer: D

Rationale: The correct term for a vegetarian diet that includes both dairy foods and eggs is 'ovolactovegetarian.' This term specifically indicates the inclusion of eggs ('ovo') and dairy ('lacto') in the diet. Choice A, 'lactovegetarian,' is incorrect because it only includes dairy products without eggs. Choice B, 'vegan,' is incorrect as it excludes all animal products, including dairy and eggs. Choice C, 'semi-vegetarian,' is incorrect as it is a term used for individuals who occasionally eat meat, poultry, or fish but primarily follow a plant-based diet.

2. Which of the following is a characteristic of essential fatty acids?

• A. They can come from both animal and plant sources.
• B. They are not manufactured by the body.
• C. They are not manufactured by the body.
• D. They are manufactured by the body.

Correct answer: B

Rationale: The correct answer is B: Essential fatty acids are not manufactured by the body. These fatty acids must be obtained through the diet because the body cannot synthesize them. Choice A is incorrect because essential fatty acids can come from both animal and plant sources, not just from an animal source. Choice C is the correct characteristic of essential fatty acids. Choice D is incorrect because essential fatty acids are not produced by the body.

3. Why are bacteria found in the colon important?

• A. synthesize important vitamins.
• B. complete the process of absorption.
• C. synthesize some minerals.
• D. finish the process of digestion.

Correct answer: A

Rationale: Bacteria found in the colon are important because they synthesize important vitamins, such as vitamin K. This aids in the body's overall health and functioning. Choice B is incorrect because absorption primarily occurs in the small intestine, not the colon. Choice C is incorrect as the synthesis of minerals is not a primary function of colon bacteria. Choice D is incorrect as the digestion process mainly occurs in the stomach and small intestine.

4. Individual nutrients are characterized by their ability to:

• A. work independently.
• B. fulfill specific metabolic roles.
• C. influence weight loss.
• D. improve mental status.

Correct answer: B

Rationale: The correct answer is B: 'fulfill specific metabolic roles.' Nutrients play essential roles in specific metabolic processes in the body such as energy production, tissue repair, and growth. Choice A, 'work independently,' is incorrect as nutrients often work synergistically rather than alone. Choice C, 'influence weight loss,' is incorrect as while some nutrients may support weight loss indirectly through metabolic processes, it is not their primary characteristic. Choice D, 'improve mental status,' is also incorrect as while some nutrients are important for brain health, their primary role is not specifically to improve mental status.

5. Which component of fat can be used to make glucose through gluconeogenesis?

• A. Glycogen
• B. Fatty acids
• C. Glycerol
• D. Monoglyceride

Correct answer: C

Rationale: The correct answer is 'Glycerol.' Glycerol, a component of fat, can be converted into glucose through gluconeogenesis. Glycogen (Choice A) is a polysaccharide stored in animals, not a component of fat. Fatty acids (Choice B) are used primarily for energy production through beta-oxidation, not for gluconeogenesis. Monoglyceride (Choice D) is a molecule formed during fat digestion, but it is not the component of fat that can be used to make glucose.
