4. She reads about Path Goal theory. Which of the following behaviors is manifested by the

• A. Recognizes staff for going beyond expectations by giving them citations
• B. Challenges the staff to take individual accountability for their own practice
• C. Admonishes staff for being laggards.
• D. Reminds staff about the sanctions for non performance.

Correct answer: B

Rationale: The correct answer is B: 'Challenges the staff to take individual accountability for their own practice.' Path-Goal theory emphasizes the leader's role in motivating and guiding their team to achieve goals. This behavior aligns with the theory as it focuses on empowering employees to take ownership of their actions and responsibilities. By challenging staff to be individually accountable, the leader is providing clear direction and support, which can enhance motivation and performance within the team. Recognizing and rewarding staff for going beyond expectations (option A) would be more aligned with a transformational leadership style. Admonishing staff for being laggards (option C) and reminding staff about sanctions (option D) are not effective leadership behaviors according to the Path-Goal theory, as they do not focus on motivating and supporting employees to reach their goals.

5. Saliva contains an enzyme that breaks down carbohydrates. What is the name of this enzyme?

• A. Pepsin
• B. Amylase
• C. Lipase
• D. Trypsin

Correct answer: B

Rationale: The correct answer is B: Amylase. Saliva contains the enzyme amylase, which is responsible for breaking down carbohydrates into simpler sugars like maltose and glucose. Pepsin (A) is an enzyme found in the stomach that breaks down proteins. Lipase (C) is an enzyme that breaks down fats, and trypsin (D) is another enzyme that breaks down proteins, but both of these are not found in saliva. Knowing the function of amylase in saliva helps in the digestion of carbohydrates, making it the correct answer.

6. Which of the following is an example of stabilizing selection?

• A. Selection that favors extreme traits in a population
• B. Selection that removes individuals with extreme traits
• C. Selection that maintains the current average trait in a population
• D. Selection that favors one specific trait over all others

Correct answer: C

Rationale: Rationale: - Stabilizing selection is a type of natural selection that favors the intermediate variants in a population, while selecting against the extreme traits. This results in the maintenance of the current average trait in the population. - Option A is incorrect because stabilizing selection does not favor extreme traits; instead, it favors the average trait. - Option B is incorrect because stabilizing selection does not remove individuals with extreme traits; it acts against extreme traits by favoring the intermediate variants. - Option D is incorrect because stabilizing selection does not favor one specific trait over all others; it favors the average trait by selecting against extreme traits.
