1. How does the potential energy of an object change when it is compressed?

• A. Potential energy decreases
• B. Potential energy increases
• C. Potential energy remains constant
• D. Potential energy becomes zero

Correct answer: b

Rationale: When an object is compressed, it stores potential energy due to its altered position or configuration.

2. Scientists compare the DNA of different organisms to understand evolutionary relationships. What is this type of evidence called?

• A. Morphological evidence (comparing body structures)
• B. Biochemical evidence (comparing molecules like proteins)
• C. Geographic distribution evidence (where organisms live)
• D. Genetic evidence (comparing DNA sequences)

Correct answer: D

Rationale: Rationale: A) Morphological evidence involves comparing body structures of organisms, which can provide information about evolutionary relationships based on physical similarities and differences. However, DNA comparison is a more direct and accurate method for understanding evolutionary relationships. B) Biochemical evidence involves comparing molecules like proteins, which can also provide insights into evolutionary relationships. However, DNA comparison is considered more reliable due to the direct relationship between DNA sequences and genetic information. C) Geographic distribution evidence refers to where organisms live and how their distribution may provide clues about evolutionary history. While this can be informative, it is not as direct or specific as comparing DNA sequences. D) Genetic evidence involves comparing DNA sequences of different organisms to understand their evolutionary relationships. DNA comparison is a powerful tool in evolutionary biology because it provides

3. St. Raphael Medical Center just opened its new Performance Improvement Department. Ms.

• A. Make an interpretation about strengths and weaknesses
• B. Identify the values of the department
• C. Identify structure, process, outcome standards & criteria
• D. Measure actual performances

Correct answer: B

Rationale: The correct answer is B: 'Identify the values of the department.' When a new department is established, it is important to define its core values, beliefs, and principles to guide its operations. This helps create a shared understanding among staff and stakeholders about the department's purpose and priorities. By identifying the values of the Performance Improvement Department at St. Raphael Medical Center, employees can align their actions with the department's mission and goals, fostering a cohesive and effective work environment. Options A, C, and D are not directly related to establishing the foundational values of a new department, making them less relevant in this context.

4. What is the basic unit of heredity?

• A. Chromosome
• B. Cell
• C. Gene
• D. Organ

Correct answer: C

Rationale: Rationale: A gene is the basic unit of heredity that carries the instructions for making proteins, which determine an organism's traits. Genes are segments of DNA located on chromosomes within the cell. While chromosomes contain many genes, a gene itself is the fundamental unit of heredity responsible for passing on genetic information from one generation to the next. Cells are the basic structural and functional units of living organisms, but genes specifically carry genetic information. Organs are composed of tissues and serve specific functions within an organism, but they are not the basic unit of heredity.

5. Which sentence uses the correlative conjunction "either/or" correctly?

• A. You can either come to the party or stay home.
• B. Either she will go to the concert, or he will.
• C. I'm not sure whether I should go swimming or running.
• D. He likes both pizza and pasta, so he can have either.

Correct answer: A

Rationale: Option Aa uses "either/or" to present two exclusive options.

6. What is the formula to calculate acceleration?

• A. Acceleration= Mass Force ​
• B. Acceleration= Force Mass ​
• C. Acceleration= Time Distance ​
• D. Acceleration= Time Change in Velocity ​

Correct answer: A

Rationale: Acceleration is calculated as the change in velocity divided by the time taken.
