Questions: Question 9 (2 points) What type of structures can be visualized using ultrasonography? A) Dense organs, such as bones. B) Air-filled organs, such as lungs. C) Soft internal structures, such as fetuses. D) Microscopic structures, such as mitochondria. Question 10 (2 points) The activities of an anatomist consist of , whereas those of a physi consist of

The answer to Question 9 is C: Soft internal structures, such as fetuses.

Explanation for each option: A) Dense organs, such as bones - Incorrect. Ultrasonography is not effective for visualizing dense structures like bones because they reflect sound waves, making it difficult to obtain clear images. B) Air-filled organs, such as lungs - Incorrect. Air impedes the transmission of ultrasound waves, making it challenging to visualize air-filled structures like lungs. C) Soft internal structures, such as fetuses - Correct. Ultrasonography is particularly useful for imaging soft tissues and structures, such as fetuses during pregnancy, because these tissues allow sound waves to pass through and reflect back, creating clear images. D) Microscopic structures, such as mitochondria - Incorrect. Ultrasonography does not have the resolution to visualize microscopic structures like mitochondria; it is used for larger, soft tissue structures.

For Question 10, the activities of an anatomist consist of studying the structure of the body, whereas those of a physiologist consist of studying the function of the body.
