1. Which term refers to the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: c

Rationale: Density is the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter (kg/m³).

2. What is the technical term for the involuntary muscular contractions that move food through the digestive tract?

• A. Segmentation
• B. Peristalsis
• C. Chylification
• D. Emulsification

Correct answer: B

Rationale: The correct answer is B: Peristalsis. Peristalsis is the coordinated, rhythmic contraction and relaxation of muscles in the digestive tract that propels food forward. This process helps move food through the esophagus, stomach, and intestines for digestion and absorption of nutrients. Segmentation (option A) is a different process involving alternating contractions in the intestines to mix food with digestive juices. Chylification (option C) is not a recognized term in digestion. Emulsification (option D) is the process of breaking down fats into smaller droplets for easier digestion, typically occurring in the small intestine with the help of bile. Therefore, peristalsis is the specific term for the involuntary muscular contractions responsible for moving food through the digestive tract.

3. Which property of a wave determines its loudness in sound waves?

• A. Amplitude
• B. Wavelength
• C. Frequency
• D. Speed

Correct answer: a

Rationale: Amplitude in sound waves relates to the loudness or intensity of the sound.

4. Identify the type of clause in the sentence "When the clock struck midnight, the magic began."

5. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in

• A. Vision
• B. Goal
• C. Philosophy
• D. Mission

Correct answer: A

Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.

6. Which term refers to the resistance of a liquid to flow?

• A. Density
• B. Viscosity
• C. Surface tension
• D. Boiling point

Correct answer: B

Rationale: Viscosity is the term that refers to the resistance of a liquid to flow. It is a measure of how thick or sticky a fluid is, and it determines how easily a liquid can flow. Density (A) is a measure of how much mass is contained in a given volume, surface tension (C) is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules, and boiling point (D) is the temperature at which a liquid changes to a vapor.
