Anatomy

1. The fundamental units of structure and function in all living organisms, including humans, are termed:

Correct answer: D

Rationale: The correct answer is D: Cells. Cells are the fundamental units of structure and function in all living organisms, including humans. They are the building blocks of life, performing various functions necessary for an organism to survive and thrive. Muscles (A) are composed of muscle tissue, which is made up of muscle cells. Organs (B) are structures made up of different types of tissues working together. Tissues (C) are groups of cells that work together to perform specific functions within an organism. However, cells are the smallest unit of life and are responsible for carrying out all the essential processes needed for an organism to function.

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

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.

3. A car skids on a wet road. What is the main force preventing the car from stopping?

Correct answer: A

Rationale: Friction opposes the motion of the car, trying to bring it to a stop. However, due to the wet surface, the friction force is not enough to overcome the car's inertia.

4. What is the process of cells dividing to produce new cells called?

Correct answer: A

Rationale: Rationale: A) Cell division is the process by which a parent cell divides into two or more daughter cells, allowing for growth, repair, and reproduction in living organisms. This process ensures that genetic material is accurately passed on to the new cells. B) Cell differentiation refers to the process by which cells become specialized to perform specific functions in an organism. While cell division is essential for cell differentiation, they are distinct processes. C) Cell growth is the increase in size or mass of a cell, which can occur before or after cell division. While cell growth is a component of the cell division process, it is not the primary process of cells dividing to produce new cells. D) Cell regeneration is the process by which damaged or lost cells are replaced by new cells. While cell division is involved in cell regeneration, it specifically refers to the overall process of cells dividing to produce new cells. Therefore, the most appropriate answer to the ques

5. Which property of a substance remains constant regardless of changes in its shape or size?

Correct answer: a

Rationale: Mass is the measure of the amount of matter in an object and remains constant regardless of changes in its shape or size.

6. What is the difference between a pure substance and a mixture?

Correct answer: A

Rationale: Rationale: - Pure substances have a definite and constant composition, meaning they are made up of only one type of atom or molecule. This composition does not vary. - Mixtures, on the other hand, are composed of two or more substances physically combined. The components of a mixture can be present in varying proportions, leading to a variable composition. - Option A correctly distinguishes between pure substances and mixtures based on the fixed composition of pure substances and the variable composition of mixtures.
