1. Which monosaccharide only occurs naturally in foods in combination with another sugar as a disaccharide?

• A. Fructose.
• B. Galactose.
• C. Sucrose.
• D. Maltose.

Correct answer: B

Rationale: The correct answer is B, galactose. Galactose naturally occurs in foods only when it is combined with glucose to form lactose, a disaccharide found in milk. Fructose is a monosaccharide found in fruits and honey. Sucrose is a disaccharide composed of glucose and fructose, commonly known as table sugar. Maltose is a disaccharide formed by the combination of two glucose molecules.

2. Where are the parotid, submandibular, and sublingual glands found?

• A. mouth
• B. stomach
• C. pancreas
• D. duodenum

Correct answer: A

Rationale: The parotid, submandibular, and sublingual glands are the main salivary glands located in the mouth. They play a crucial role in producing saliva, which aids in digestion. The stomach (choice B) is where gastric juices are produced, the pancreas (choice C) secretes digestive enzymes into the small intestine, and the duodenum (choice D) is the first part of the small intestine where most chemical digestion occurs. Therefore, the correct answer is the mouth (choice A) as it is where these salivary glands are situated.

3. A characteristic of saturated fats is that they are:

• A. mostly found in animal products.
• B. solid at room temperature.
• C. composed of many double bonds.
• D. found primarily in vegetable products.

Correct answer: A

Rationale: The correct answer is A: 'mostly found in animal products.' Saturated fats are primarily found in animal products such as meat, dairy, and eggs. They are typically solid at room temperature. Choice B is incorrect because saturated fats are solid at room temperature, not liquid. Choice C is incorrect because saturated fats do not have double bonds; they have single bonds between carbon atoms. Choice D is incorrect because saturated fats are mainly found in animal products, not vegetable products.

4. Which of the following is an example of a protein?

• A. Saline.
• B. Hemoglobin.
• C. Cellulose.
• D. Prostaglandins.

Correct answer: B

Rationale: Hemoglobin is a protein that carries oxygen in the blood, making it the correct answer. Choice A, Saline, is a salt solution and not a protein. Choice C, Cellulose, is a complex carbohydrate found in the cell walls of plants, not a protein. Choice D, Prostaglandins, are lipid compounds with hormone-like effects, not proteins.

5. Which of the following provides the best source of nutrients?

• A. specific food combinations.
• B. a variety of foods.
• C. individual foods.
• D. a variety of food supplements.

Correct answer: B

Rationale: A variety of foods is the best source of nutrients because it ensures a balanced intake of all essential nutrients required by the body. Option A, specific food combinations, may not provide all necessary nutrients as relying on only a few types of food may lead to deficiencies. Option C, individual foods, also may not provide a complete range of nutrients necessary for overall health. Option D, a variety of food supplements, is not the best source of nutrients as whole foods are generally more beneficial due to their natural nutrient composition and bioavailability.
