1. Classifications of human tissues exclude:

• A. Epithelial tissue
• B. Nervous tissue
• C. Adipose tissue (a specialized form of connective tissue)
• D. Bony tissue

Correct answer: D

Rationale: The correct answer is D: 'Bony tissue.' Classifications of human tissues typically include four main types: epithelial, connective, muscular, and nervous tissue. Bony tissue, also known as osseous tissue, is a specialized form of connective tissue that forms bones in the skeletal system. While bony tissue is an essential component of the human body, it is not typically categorized separately as a distinct tissue type in general tissue classifications. Therefore, it is the exception from the list provided in the question, making it the correct answer.

2. A study finds a link between increased screen time and lower academic performance. What additional information would be most helpful in interpreting this finding?

• A. The average socioeconomic status of the study participants.
• B. The specific types of screen activities participants engaged in.
• C. Whether the students had access to healthy meals and snacks.
• D. The participants' ages and grade levels.

Correct answer: B

Rationale: Knowing the specific types of screen activities participants engaged in would provide crucial context for interpreting the link between increased screen time and lower academic performance. For example, if the majority of screen time was spent on educational apps or programs, the impact on academic performance may differ compared to if the screen time was mostly spent on social media or gaming. Understanding the nature of screen activities can help determine the potential mechanisms behind the observed relationship.

3. He wants to influence the customary way of thinking and behaving that is shared by the

• A. Organizational chart
• B. Cultural network
• C. Organizational structure
• D. Organizational culture

Correct answer: A

Rationale: The correct answer is A: "Organizational chart." In the context of the question, the individual is aiming to impact the established patterns of thinking and behavior within a group or organization. An organizational chart typically depicts the formal structure of an organization, including roles, relationships, and reporting lines. By influencing the organizational chart, the individual can potentially shape the hierarchical structure and decision-making processes, thereby impacting the customary way of thinking and behaving within the organization. Options B, C, and D do not directly refer to the visual representation of roles and relationships within an organization, making them incorrect choices for this question.

4. The passage implies that achieving energy sustainability requires...

• A. solely relying on renewable energy sources for electricity generation.
• B. a combination of advancements in renewable energy production and management technologies.
• C. prioritizing economic benefits over environmental concerns when making energy choices.
• D. focusing solely on reducing energy consumption without addressing production sources.

Correct answer: B

Rationale: The passage emphasizes the need for both increasing renewable energy and managing its fluctuations, suggesting B as the key to sustainability.

5. Which part of the neuron receives incoming signals from other neurons and conducts them toward the cell body?

• A. Axon
• B. Dendrite
• C. Synapse
• D. Myelin sheath

Correct answer: b

Rationale: The correct answer is B: Dendrite. Dendrites are the part of the neuron that receive incoming signals from other neurons and conduct them toward the cell body. They play a crucial role in communication between neurons by receiving neurotransmitters released from neighboring neurons. Axons transmit signals away from the cell body, synapses are the junctions where neurons communicate with each other, and myelin sheath is a fatty insulation that surrounds and protects axons. Therefore, in this scenario, dendrites are specifically responsible for receiving and conducting incoming signals towards the cell body.

6. What is the process by which muscle tissue wastes away due to disuse or lack of nutrients?

• A. Hypertrophy
• B. Atrophy
• C. Fibrosis
• D. Rigor mortis

Correct answer: B

Rationale: The correct answer is B: Atrophy. Atrophy is the process by which muscle tissue wastes away due to disuse or lack of nutrients. When muscles are not regularly used or do not receive enough nutrients, they can decrease in size and strength. Hypertrophy, on the other hand, refers to the increase in muscle size and strength through exercise and proper nutrition. Fibrosis is the formation of excess fibrous connective tissue in an organ or tissue, leading to scarring. Rigor mortis is a temporary stiffening of muscles that occurs after death. Therefore, in this context, atrophy best describes the wasting away of muscle tissue due to disuse or lack of nutrients.
