1. The Acceptable Macronutrient Distribution Range for fat recommends that the percentage of total kcalories from fat should fall between:

Correct answer: C

Rationale: The Acceptable Macronutrient Distribution Range (AMDR) for fat suggests that 20% to 35% of total kcalories should come from fat. This range is recommended to maintain good health. Choices A, B, and D are incorrect because they do not fall within the specified range. A lower percentage (10-20%) may not provide enough essential fatty acids, while a higher percentage (30-45%) may increase the risk of health issues associated with excessive fat consumption.

2. Which of the following is a characteristic of essential fatty acids?

Correct answer: B

Rationale: The correct answer is B: Essential fatty acids are not manufactured by the body. These fatty acids must be obtained through the diet because the body cannot synthesize them. Choice A is incorrect because essential fatty acids can come from both animal and plant sources, not just from an animal source. Choice C is the correct characteristic of essential fatty acids. Choice D is incorrect because essential fatty acids are not produced by the body.

3. Carbohydrates are composed of a combination of carbon, hydrogen, and which other element?

Correct answer: A

Rationale: Carbohydrates are composed of carbon, hydrogen, and oxygen. These three elements combine to form the basic structure of carbohydrates. Oxygen is an essential element in carbohydrates, contributing to their chemical composition. Choice B (nitrogen) is incorrect as nitrogen is not a typical component of carbohydrates. Choice C (water) is incorrect as water is not an element but a compound composed of hydrogen and oxygen. Choice D (glucose) is incorrect as glucose is a specific type of sugar, not an element found in the composition of carbohydrates.

4. What does the Tolerable Upper Intake Level (UL) represent?

Correct answer: D

Rationale: The Tolerable Upper Intake Level (UL) represents the highest amount of a nutrient that can be safely consumed without causing adverse health effects. It is not a replacement for Recommended Dietary Allowances (RDAs) (choice A) which are nutrient intake recommendations. While the UL is established to prevent toxicity, it is not a completely safe level for people of all ages (choice B). It is also not a potentially toxic level of intake of a nutrient (choice C), but rather the level that is unlikely to cause adverse health effects.

5. What types of muscular movement occur in the intestine?

Correct answer: A

Rationale: The correct answer is A: Longitudinal and circular. Longitudinal and circular muscles are responsible for the movements that help propel food through the intestine. Choice B, expulsion and traction, is incorrect as these terms do not specifically relate to the types of muscular movement in the intestine. Choice C, tonus and clonus, refers to different types of muscle contractions and are not the primary movements in the intestine. Choice D, intermittent and continuous, does not accurately describe the specific types of muscular movement that occur in the intestine.
