1. What are the key differences between cytokinesis in plant and animal cells?

• A. Animal cells utilize an actomyosin ring for cleavage furrow formation, while plant cells lack this mechanism.
• B. Plant cells rely on the assembly of a cell plate in the center of the dividing cell, ultimately separating the cytoplasm.
• C. Cytokinesis in both plant and animal cells is driven by the expansion of the endoplasmic reticulum.
• D. Both types of cells achieve cytokinesis through similar membrane pinching and constriction mechanisms.

Correct answer: B

Rationale: Rationale: A) Animal cells utilize an actomyosin ring for cleavage furrow formation, while plant cells lack this mechanism. - This statement is true. Animal cells use an actomyosin ring to form a cleavage furrow during cytokinesis, while plant cells do not have this mechanism. Instead, plant cells form a cell plate. B) Plant cells rely on the assembly of a cell plate in the center of the dividing cell, ultimately separating the cytoplasm. - This statement is correct. Plant cells form a cell plate in the middle of the dividing cell during cytokinesis. The cell plate eventually develops into a new cell wall that separates the two daughter cells. C) Cytokinesis in both plant and animal cells is driven by the expansion of the endoplasmic reticulum. - This

2. She takes pride in saying that the hospital has a decentralized structure. Which of the

• A. Flat organization
• B. Participatory approach
• C. Shared governance
• D. Tall organization

Correct answer: B

Rationale: The correct answer is B: 'Participatory approach.' In a decentralized structure, decision-making authority is dispersed throughout the organization rather than being concentrated at the top. A participatory approach involves employees at all levels having a say in decisions that affect their work, fostering collaboration and empowerment. This contrasts with a tall organization, which has many layers of management and a more centralized decision-making process. While shared governance can involve decentralized decision-making, it specifically refers to a model where nurses and other healthcare professionals have a voice in shaping policies and practices within their organization, which is not necessarily the same as a decentralized structure.

3. Julius orients his staff on the patterns of reporting relationship throughout the organization.

• A. Span of control
• B. Hierarchy
• C. Esprit d’ corps
• D. Unity of direction

Correct answer: B

Rationale: The correct answer is B: Hierarchy. Hierarchy refers to the structure of authority and responsibility within an organization, including the levels of management and the reporting relationships. In this scenario, Julius is orienting his staff on the patterns of reporting relationships, which is a key aspect of hierarchy. Span of control refers to the number of employees a manager can effectively supervise, esprit de corps pertains to team spirit and unity among employees, and unity of direction relates to ensuring all activities are focused on the same objectives. Therefore, the most appropriate term for Julius's action is hierarchy.

4. The term "symbiotic relationship" describes an interaction between two organisms where:

• A. One organism benefits and the other is unaffected
• B. Both organisms are harmed by the interaction
• C. One organism benefits and the other is negatively impacted
• D. Both organisms benefit from the interaction

Correct answer: D

Rationale: Rationale: In a symbiotic relationship, both organisms involved benefit from the interaction. This mutually beneficial relationship can take different forms, such as mutualism where both organisms benefit, commensalism where one organism benefits and the other is unaffected, or parasitism where one organism benefits at the expense of the other. In this case, the term "symbiotic relationship" specifically refers to a scenario where both organisms derive some form of benefit from their interaction.

5. Muscles that work together to produce a specific movement are called

• A. Antagonistic muscles
• B. Agonistic muscles
• C. Synergistic muscles
• D. Flexors and extensors

Correct answer: C

Rationale: Synergistic muscles are the correct answer because they are muscles that work together to produce a specific movement. These muscles coordinate their actions to achieve a common goal, such as bending the elbow or extending the knee. Antagonistic muscles work in opposition to each other, while agonistic muscles are the primary movers in a particular movement. Flexors and extensors refer to specific muscle groups that perform opposing actions, rather than working together synergistically. Understanding the concept of synergistic muscles is essential in biomechanics and exercise science.

6. How does an increase in temperature generally affect the solubility of most solid solutes in a liquid solvent?

• A. It increases solubility
• B. It decreases solubility
• C. It has no effect on solubility
• D. It depends on the nature of the solute

Correct answer: a

Rationale: In general, increasing temperature tends to increase the solubility of most solid solutes in liquid solvents. The other choices do not accurately describe the effect of temperature on solubility.
