1. Which of the following sandwiches is high in saturated fatty acids?

Correct answer: B

Rationale: The correct answer is Grilled cheese because it is high in saturated fatty acids due to the dairy fat content in cheese. Tuna salad, turkey and sprouts, and peanut butter and jelly do not contain as high levels of saturated fatty acids as grilled cheese. Tuna salad typically contains mayonnaise which may contribute to some saturated fat content, but it is generally lower compared to the cheese in grilled cheese. Turkey and sprouts are leaner options, while peanut butter and jelly are higher in unsaturated fats rather than saturated fats.

2. What is one function of essential fatty acids?

Correct answer: A

Rationale: Essential fatty acids play a crucial role in improving skin integrity by supporting the structure and function of cell membranes. This helps in maintaining healthy skin and promoting overall well-being. The other choices are incorrect because essential fatty acids do not directly control lipid digestion, reduce blood clotting time, or form chylomicrons.

3. What is the muscle layer on the outside of the intestinal wall called?

Correct answer: A

Rationale: The correct answer is A: serosa. The serosa is the outermost layer of the intestinal wall, providing a protective covering. Choice B, mucosa, is the innermost layer responsible for absorption. Choice C, submucosa, lies beneath the mucosa and contains blood vessels and nerves. Choice D, muscularis mucosae, is a smooth muscle layer located within the mucosa, helping to create folds in the intestinal lining to increase surface area for absorption.

4. Feces are composed mainly of bacteria, mucosal cells, mucus, and what else?

Correct answer: C

Rationale: The correct answer is 'C: fiber.' Feces are primarily made up of indigestible material, such as fiber. Bile (choice A) is produced by the liver to aid in digestion but is not a major component of feces. Enzymes (choice B) are involved in digestion but are not a significant component of feces. Chyme (choice D) is the semi-fluid mass of partially digested food that moves from the stomach to the small intestine and is not a major component of feces.

5. Which mineral helps strengthen tooth enamel and prevent dental caries?

Correct answer: C

Rationale: The correct answer is C, Fluoride. Fluoride is a mineral known for its ability to strengthen tooth enamel and prevent dental caries. While calcium (Choice A) is essential for strong bones and teeth, it is not specifically known for preventing dental caries. Phosphorus (Choice B) is crucial for bone health but is not directly associated with preventing dental caries. Zinc (Choice D) is not typically recognized for strengthening tooth enamel or preventing dental caries.
