Biology
1. What is the main component of sweat?
- A. Urea
- B. Glucose
- C. Water
- D. Electrolytes
Correct answer: C
Rationale: Rationale: - Sweat is primarily composed of water, making up the majority of its content. Water helps regulate body temperature by evaporating from the skin's surface, which cools the body down. - While sweat does contain small amounts of other substances like urea, glucose, and electrolytes, water is the main component that is secreted by sweat glands to help regulate body temperature during physical activity or in response to heat.
2. During embryonic development, most vertebrates exhibit structures called pharyngeal pouches. These pouches eventually develop into different structures in various vertebrate groups, such as the human jaw and inner ear. Pharyngeal pouches are an example of:
- A. Analogous structures with different evolutionary origins but similar functions
- B. Homologous structures with a common evolutionary origin but diverse functions
- C. Vestigial structures that no longer serve a vital function in some organisms
- D. Atavisms, the reappearance of a trait absent in recent generations
Correct answer: B
Rationale: Rationale: Pharyngeal pouches in vertebrates are an example of homologous structures because they share a common evolutionary origin. Despite developing into different structures in various vertebrate groups, such as the jaw and inner ear in humans, these structures originated from the same ancestral feature. This concept of homology highlights the evolutionary relationship between different species and how structures can be modified over time to serve different functions while retaining a common origin.
3. The speaker's enthusiasm was contagious. Which word is the noun form of the adjective "enthusiastic"?
- A. enthusiastic
- B. enthusiastically
- C. enthusiasm
- D. enthuse
Correct answer: C
Rationale: Nouns can be formed from adjectives using various suffixes.
4. How does the acceleration of an object change if the force acting on it is doubled?
- A. Acceleration is halved
- B. Acceleration doubles
- C. Acceleration remains unchanged
- D. Acceleration quadruples
Correct answer: b
Rationale: According to Newton's second law (F = ma), if force is doubled and mass remains constant, acceleration doubles.
5. Julius plans to revisit the organizational chart of the department. He plans to create a new
- A. Box
- B. Solid line
- C. Broken line
- D. Dotted line
Correct answer: B
Rationale: The correct answer is B: 'Solid line.' In organizational charts, solid lines typically represent formal reporting relationships, indicating direct authority and responsibility between positions. Creating a new solid line on the chart would signify a new formal reporting relationship within the department. This can be important for clarifying roles, communication channels, and decision-making processes. Boxes represent positions or roles in the organizational structure, while broken lines and dotted lines are typically used for informal relationships or advisory roles, rather than formal reporting relationships.
6. One staff suggests that they review the pattern of nursing care that they are using, which is
- A. job description
- B. system used to deliver care
- C. manual of procedure
- D. rules to be followed
Correct answer: B
Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.
