1. She surfs the internet for more information about leadership styles. She reads about shared

A. Leadership behavior is generally determined by the relationship between the leaderâ€™s
B. Leaders believe that people are basically good and need not be closely controlled
C. Leaders rely heavily on visioning and inspire members to achieve results
D. Leadership is shared at the point of care.

Correct answer: B

Rationale: The correct answer is B because the statement 'Leaders believe that people are basically good and need not be closely controlled' aligns with the concept of shared leadership. Shared leadership involves distributing leadership responsibilities and authority among team members based on the belief that everyone has valuable contributions to make. This approach fosters a sense of trust and empowerment within the team, allowing individuals to take initiative and collaborate effectively. In contrast, option A refers to leadership behavior being determined by the relationship between the leader and followers, which is not directly related to the concept of shared leadership. Option C emphasizes visioning and inspiration, which are important aspects of leadership but do not specifically address the shared nature of leadership. Option D mentions leadership being shared at the point of care, which is too specific and does not encompass the broader concept of shared leadership.

2. The measurable electrical activity of the brain is recorded by a:

A. CAT scan
B. MRI scan
C. Electroencephalogram (EEG)
D. X-ray

Correct answer: C

Rationale: The correct answer is C: "Electroencephalogram (EEG)". An EEG is a non-invasive test that measures the electrical activity of the brain by placing electrodes on the scalp. It is specifically designed to record brain wave patterns, making it a valuable tool in diagnosing conditions such as epilepsy, sleep disorders, and brain injuries. A CAT scan (A) and MRI scan (B) are imaging techniques that show the structure of the brain, while an X-ray (D) is not typically used to measure brain electrical activity.

3. The number of protons in an atom determines its:

A. Mass number
B. Atomic number
C. Atomic number
D. Valence electron count

Correct answer: B

Rationale: The atomic number (Z) equals the number of protons and defines an element's core identity.

4. Identify the pronoun in the following sentence: She quickly finished her homework before dinner.

A. quickly
B. finished
C. her
D. before

Correct answer: C

Rationale: Pronouns take the place of nouns. "Her" replaces a specific female person's name.

5. . Edema, characterized by swelling due to fluid buildup, can be a sign of:

A. Heart failure
B. Liver disease
C. Lymphatic system dysfunction
D. All of the above

Correct answer: D

Rationale: Edema, which is the accumulation of fluid in tissues leading to swelling, can be caused by various medical conditions. Heart failure can result in fluid retention due to the heart's inability to pump effectively, leading to edema. Liver disease can cause edema by impairing the liver's ability to produce proteins that help maintain fluid balance. Dysfunction of the lymphatic system can also lead to edema, as the lymphatic vessels play a crucial role in draining excess fluid from tissues. Therefore, all the options (heart failure, liver disease, and lymphatic system dysfunction) can contribute to the development of edema, making 'All of the above' the correct answer.

6. Explain how a single gene mutation can lead to multiple phenotypes depending on the organism.

A. Pleiotropy describes the effect of one gene influencing multiple seemingly unrelated traits.
B. Epigenetics involves environmental factors modifying gene expression without altering the DNA sequence.
C. Genetic drift refers to random changes in allele frequencies within a population.
D. Gene regulation controls the timing and level of gene expression within an organism.

Correct answer: A

Rationale: A single gene mutation can affect different biochemical pathways or developmental processes, leading to a cascade of downstream effects and diverse phenotypic consequences.
