Correct Answer: D

Rationale: Trypsin and chymotrypsin are enzymes involved in protein digestion. These enzymes are secreted by the pancreas, not the small intestine, liver, or stomach. The pancreas plays a crucial role in producing digestive enzymes that aid in breaking down proteins in the small intestine. The small intestine is the site where these enzymes act, not where they are secreted. The liver is responsible for producing bile, not digestive enzymes. The stomach secretes gastric juices but not trypsin and chymotrypsin. Therefore, the correct answer is the pancreas.

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.

Correct Answer: B

Rationale: The correct answer is B, fructose. Sucrose is a disaccharide composed of one molecule of glucose and one molecule of fructose. Maltose (choice A) is composed of two glucose molecules, galactose (choice C) is a monosaccharide, and lactose (choice D) is composed of one molecule of glucose and one molecule of galactose. Therefore, fructose is the correct choice for the second component of sucrose.

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.
