1. High intakes of which of the following interfere with copper absorption and can lead to a deficiency?
- A. chromium
- B. sodium
- C. zinc
- D. manganese
Correct answer: C
Rationale: The correct answer is C, zinc. High intakes of zinc can interfere with copper absorption, potentially leading to copper deficiency. Copper is essential for various bodily functions, including iron metabolism. Choice A, chromium, is incorrect because chromium does not interfere with copper absorption. Choice B, sodium, and Choice D, manganese, are also incorrect as they do not interfere with copper absorption.
2. Which of the following foods provides the most protein?
- A. Beans
- B. Red peppers
- C. Asparagus
- D. Celery
Correct answer: A
Rationale: The correct answer is 'Beans.' Beans are a rich source of plant-based protein, making them the best option among the listed foods for protein content. Red peppers, asparagus, and celery are not significant sources of protein compared to beans, hence they are incorrect choices for this question.
3. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?
- A. Ionic bond
- B. Covalent bond
- C. Functional group
- D. Metallic bond
Correct answer: A
Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.
4. In comparison to infants born to women of normal weight, infants born to obese women are _____.
- A. less likely to have heart defects
- B. more likely to be of very low birthweight
- C. less likely to experience a complicated birth
- D. more likely to have neural tube defects
Correct answer: D
Rationale: Infants born to obese women are more likely to have neural tube defects compared to infants born to women of normal weight. This increased risk is attributed to factors such as poor maternal nutrition and increased inflammation during pregnancy. Choice A is incorrect because infants born to obese women have a higher risk of heart defects. Choice B is incorrect as infants born to obese women are more likely to have higher birthweights. Choice C is incorrect as obese women are more likely to experience complications during birth.
5. Which of the following foods or beverages would offer the most nutrients per calorie?
- A. chicken
- B. wine
- C. white bread
- D. broccoli
Correct answer: D
Rationale: Broccoli is indeed the correct answer. Broccoli is considered nutrient-dense, meaning it provides a significant amount of essential nutrients like vitamins, minerals, and fiber while being relatively low in calories. On the other hand, choices A, B, and C are not as nutrient-dense as broccoli. Chicken can be nutritious but may vary in nutrient content depending on the cut and preparation method. Wine, although containing antioxidants like resveratrol, is not a significant source of essential nutrients. White bread is often low in nutrients and fiber compared to whole grain options, making it less nutrient-dense than broccoli.
