1. Which respiratory structure is responsible for the humidification and warming of inhaled air?

Correct answer: C

Rationale: The nasal passages are responsible for humidifying and warming inhaled air before it reaches the lungs. The mucous membranes in the nasal passages help add moisture to the air and warm it to body temperature. This process is crucial for protecting the lung tissues from potential damage caused by cold and dry air, ensuring optimal conditions for respiration. The trachea (Choice A) is responsible for conducting air to and from the lungs, the larynx (Choice B) is involved in sound production and protecting the airway during swallowing, and the bronchi (Choice D) are the branches of the trachea that further divide to deliver air to the lungs but are not primarily responsible for humidifying and warming inhaled air.

2. Which of the following functions is not controlled by the autonomic nervous system?

Correct answer: B

Rationale: The correct answer is B: Walking. Walking is not directly controlled by the autonomic nervous system. Walking is a voluntary action governed by the somatic nervous system, which controls voluntary skeletal muscle movement. The autonomic nervous system, on the other hand, regulates functions that are involuntary, such as digestion, heartbeat, and temperature regulation. Choices A, C, and D are all functions controlled by the autonomic nervous system. Digestion involves processes like peristalsis and secretion of digestive enzymes, heartbeat is regulated by the autonomic nervous system to maintain blood pressure and circulation, and temperature regulation includes responses like sweating or shivering to maintain body temperature within a narrow range.

3. Which system is responsible for transporting nutrients, gases, and wastes in the body?

Correct answer: C

Rationale: The circulatory system is responsible for transporting nutrients, gases, and wastes to and from the cells in the body. It includes the heart, blood vessels, and blood, which work together to distribute oxygen, nutrients, and remove waste products throughout the body. The respiratory system is primarily involved in gas exchange, the digestive system breaks down food for absorption, and the nervous system is responsible for transmitting signals throughout the body.

4. What is the relationship between the frequency and period of a wave?

Correct answer: D

Rationale: The correct relationship between frequency and period of a wave is that Period = 1/Frequency. This relationship indicates that the period of a wave is the reciprocal of its frequency. Frequency refers to the number of complete cycles of a wave occurring in a unit of time, while the period is the time taken for one complete cycle of the wave to occur. As frequency and period are inversely related, the correct formula to express this relationship is Period = 1/Frequency. Choice A is incorrect as frequency and period are related. Choice B is incorrect as frequency and period are not equal. Choice C is incorrect as it suggests that frequency is directly proportional to period, which is not the case.

5. Which of the following is NOT a common symptom of lactose intolerance?

Correct answer: D

Rationale: A) Gas: Gas is a common symptom of lactose intolerance. When lactose is not properly digested, it can ferment in the colon, leading to the production of gas. B) Bloating: Bloating is another common symptom of lactose intolerance. The buildup of gas in the digestive system can cause bloating and discomfort. C) Diarrhea: Diarrhea is a common symptom of lactose intolerance. When lactose is not broken down in the small intestine, it can draw excess water into the colon, resulting in diarrhea. D) Nausea: Nausea is not a common symptom of lactose intolerance. While some individuals may experience mild stomach discomfort or cramps, nausea is not typically associated with lactose intolerance.
