Anatomy

1. The following epithelium lines the inner surface of the oral cavity, providing a barrier against external insults. Which type of epithelium best fits this description?

Correct answer: B

Rationale: The correct answer is B: Stratified squamous epithelium. The oral cavity is subjected to mechanical stress and potential injuries from chewing and abrasive food particles. Stratified squamous epithelium is the best choice for this location due to its multiple layers of cells that provide protection against wear and tear. This type of epithelium is well-suited for areas that require a tough, protective barrier, making it ideal for lining the oral cavity. In contrast, simple squamous epithelium is a single layer of flat cells found in locations where filtration or diffusion occurs, not where protection is needed. Simple columnar epithelium and pseudostratified columnar epithelium are better suited for absorption and secretion functions in areas like the intestines and respiratory tract, respectively.

2. What property of matter refers to the amount of space occupied by an object?

Correct answer: b

Rationale: Volume measures the amount of space occupied by an object.

3. As a manager, she focuses her energy on both the quality of services rendered to the patients

Correct answer: B

Rationale: The correct answer is 'B: Organization man management.' This type of management focuses on maintaining the efficiency and structure of an organization. In this scenario, the manager's emphasis on the quality of services aligns with the principles of organization man management, which prioritizes the coordination of tasks and resources to achieve optimal results within the organization. This contrasts with 'Country club management,' which emphasizes employee satisfaction over task accomplishment; 'Team management,' which focuses on collaboration and teamwork; and 'Authority-obedience management,' which centers on strict hierarchical control. Therefore, the most appropriate choice is 'B: Organization man management.'

4. The three main types of muscle tissue in the human body are:

Correct answer: A

Rationale: The correct answer is A: Smooth, cardiac, and voluntary skeletal. Smooth muscle is found in the walls of internal organs and blood vessels, cardiac muscle makes up the heart, and voluntary skeletal muscle is attached to the bones and responsible for movement. Choice B is incorrect because cardiac muscle is involuntary, not voluntary. Choice C is incorrect because smooth muscle and cardiac muscle are involuntary, not voluntary. Choice D is incorrect because 'striated' and 'non-striated' refer to the appearance of muscle fibers, not the main types of muscle tissue in the body.

5. The phrase "disruptions to ecosystems" refers to

Correct answer: B

Rationale: The phrase suggests profound impacts on ecological balance and species interactions, aligning with B.

6. What property of a substance refers to its ability to be drawn into thin wires without breaking?

Correct answer: c
