1. What types of muscular movement occur in the intestine?
- A. Longitudinal and circular.
- B. Expulsion and traction.
- C. Tonus and clonus.
- D. Intermittent and continuous.
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.
2. Which of the following sugars tastes the sweetest?
- A. Glucose
- B. Sucrose
- C. Galactose
- D. Fructose
Correct answer: D
Rationale: Fructose is known to be the sweetest among naturally occurring sugars. While glucose, sucrose, and galactose also have sweet tastes, fructose is commonly perceived as the sweetest due to its higher level of sweetness. Glucose is a simple sugar found in many carbohydrates; sucrose is table sugar composed of glucose and fructose; galactose is a component of lactose found in dairy products. However, when comparing the sweetness levels of these sugars, fructose stands out as the sweetest.
3. What is the cause of gas formation in the colon?
- A. Consuming refined foods.
- B. Drinking excess water.
- C. Swallowing air while eating.
- D. Bacterial action on organic compounds.
Correct answer: D
Rationale: Gas formation in the colon is primarily due to bacterial fermentation of undigested carbohydrates. Choice A, consuming refined foods, is incorrect as gas formation is not directly linked to refined foods but rather undigested carbohydrates. Choice B, drinking excess water, is incorrect as water consumption does not lead to gas formation in the colon. Choice C, swallowing air while eating, is incorrect as this may cause belching but not gas formation in the colon. The correct answer is D because bacterial action on organic compounds, specifically undigested carbohydrates, leads to gas production in the colon.
4. In addition to calcium, the major minerals needed to build and maintain bone tissue include:
- A. potassium
- B. iron
- C. phosphorus
- D. fluoride
Correct answer: C
Rationale: The correct answer is C: phosphorus. Phosphorus, along with calcium, is essential for bone health and maintenance. Potassium (choice A) is important for muscle function, iron (choice B) is crucial for red blood cell production, and fluoride (choice D) helps prevent tooth decay but is not a major mineral needed for bone tissue.
5. Nutrients interact in the body to regulate metabolic processes, build and repair tissue, and to:
- A. provide energy.
- B. control cellular wastes.
- C. control hormone levels.
- D. regulate absorption.
Correct answer: A
Rationale: The correct answer is A: provide energy. Nutrients play a crucial role in providing energy for the body's various functions. While they do help in regulating metabolic processes and in building and repairing tissue, the primary function related to energy production. Choices B, C, and D are incorrect as nutrients are not primarily responsible for controlling cellular wastes, hormone levels, or absorption.
