Correct Answer: B

Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.

Correct Answer: C

Rationale: The correct answer is A and B. Switching to more nutrient-dense foods can help Miguel feel full despite eating enough calories. Nutrient-dense foods provide essential nutrients and are more satisfying. Drinking adequate water is also crucial for overall health and can help with feelings of fullness. Choice D is incorrect because while fat can contribute to satiety, it should be consumed in balance with other nutrients. Consuming foods with high fat content excessively may lead to other health issues and does not address the underlying problem of feeling constantly hungry despite eating.

Correct Answer: C

Rationale: Corrected Rationale: Protein provides 4 kcal per gram, making it a good source of energy to increase caloric intake. While fiber and water are important for other aspects of health, they do not provide energy like protein does. Vitamins are essential for various bodily functions but do not contribute directly to caloric intake.

Correct Answer: A

Rationale: The correct answer is Marasmus. Marasmus is a severe form of protein-energy malnutrition (PEM) that leads to muscle wasting, hanging skin, delayed growth, and changes in saliva. These symptoms are commonly seen in vulnerable populations such as children, homeless individuals, older adults, and substance abusers. Kwashiorkor, on the other hand, is characterized by edema, a distended belly, and skin lesions. Anemia is a condition characterized by a low red blood cell count, leading to fatigue and weakness. Noma is a severe infection affecting the face, particularly the mouth and jaw area.
