1. Are the ears lateral to the eyes?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. Lateral means towards the side or away from the midline. In human anatomy, the ears are located on the sides of the head, which is indeed lateral to the eyes that are positioned more towards the front of the face. Therefore, the statement that the ears are lateral to the eyes is true. Choice B is incorrect because the ears are not positioned closer to the midline than the eyes. Choice C is incorrect as the relationship between the ears and eyes in terms of lateral positioning can be determined anatomically. Choice D is incorrect as there is a clear anatomical relationship between the ears and eyes.

2. Is a cell the basic unit of structure and function of an organism?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. A cell is indeed the basic unit of structure and function of an organism. Cells are the smallest independently functioning unit in the structure of an organism and carry out vital functions necessary for life. Choice B, False, is incorrect because cells are universally recognized as the fundamental unit of life. Choice C, Not Sure, is incorrect as the role of a cell as the basic unit of an organism's structure and function is a well-established scientific fact. Choice D, None of the above, is incorrect as the statement provided in the question is true.

3. Metabolism refers to all of the chemical reactions in an organism that support life. Is this statement true?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The statement is true. Metabolism indeed refers to all of the chemical reactions in an organism that support life. It is essential for various processes in the body, including converting food into energy, building and repairing tissues, and eliminating waste products. Choice B is incorrect because metabolism does encompass all chemical reactions that sustain life. Choice C is incorrect as the definition of metabolism is clear. Choice D is incorrect as the statement provided is true.

4. Does the diaphragm separate the thoracic and abdominopelvic cavities?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. The diaphragm is a dome-shaped muscle that separates the thoracic cavity, which contains the heart and lungs, from the abdominopelvic cavity, which contains organs such as the stomach, liver, and intestines. It plays a crucial role in breathing by contracting and relaxing to help with the process of respiration. Therefore, the statement is accurate. Choice B is incorrect because the diaphragm indeed separates these two cavities. Choice C is incorrect as the information provided allows one to determine the correct answer. Choice D is incorrect as the correct answer is 'True.'

5. What is the most useful application of ultrasonography for diagnostic examination?

• A. dense organs, such as bones.
• B. air-filled organs, such as lungs.
• C. soft internal structures, such as fetuses.
• D. microscopic structures.

Correct answer: C

Rationale: Ultrasonography is a medical imaging technique that uses sound waves to visualize internal body structures. It is particularly effective for examining soft tissues like organs, blood vessels, and fetuses. Choice A is incorrect because bones are better visualized using techniques like X-rays. Choice B is incorrect as air-filled organs like lungs are not well visualized with ultrasound due to air being a poor conductor of sound waves. Choice D is incorrect since ultrasonography cannot visualize structures at a microscopic level, as it is used for larger internal structures.
