1. He likewise stresses the need for all the employees to follow orders and instructions from

• A. Scalar chain
• B. Discipline
• C. Unity of command
• D. Order

Correct answer: B

Rationale: The correct answer is B: 'Discipline.' In a business context, discipline refers to the adherence to rules, orders, and instructions to ensure smooth operations and efficiency. The concept of discipline is essential in maintaining order, consistency, and productivity within an organization. It encompasses obeying rules, following instructions, and respecting authority. While the other options like 'Scalar chain,' 'Unity of command,' and 'Order' are important principles in management, they do not directly address the importance of employees adhering to orders and instructions, which is the central focus in this question. Therefore, 'Discipline' is the most suitable answer in this context.

2. The process by which a cell divides to produce two daughter cells is called:

• A. Mitosis
• B. Meiosis
• C. Differentiation
• D. Transformation

Correct answer: A

Rationale: The correct answer is A: "Mitosis." Mitosis is the process of cell division in which a cell duplicates its chromosomes and divides into two identical daughter cells. This is a crucial mechanism for growth, repair, and maintenance of multicellular organisms. Meiosis (option B) is a different type of cell division that produces gametes with half the number of chromosomes. Differentiation (option C) refers to the process by which cells become specialized for specific functions. Transformation (option D) is a term used in molecular biology to describe the uptake of foreign DNA by a cell. In this question, the specific process of cell division leading to the production of two daughter cells aligns with mitosis.

3. The urethra is the tube that carries urine from the bladder to the outside of the body. How does urine flow through the urethra?

• A. Continuously
• B. Only when the bladder is completely full
• C. Under voluntary control of sphincter muscles
• D. A combination of b) and c)

Correct answer: C

Rationale: The correct answer is C: "Under voluntary control of sphincter muscles." The urethra is the tube responsible for carrying urine from the bladder to the outside of the body. Urine flow through the urethra is not continuous but rather under voluntary control. The sphincter muscles, located at the opening of the bladder and urethra, help control the release of urine. This control allows individuals to regulate when and where they empty their bladder, providing a mechanism to prevent involuntary leakage of urine. Therefore, option C accurately describes how urine flows through the urethra.

4. 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.

5. 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.

6. What is the main function of the gallbladder?

• A. To store and concentrate bile
• B. To produce digestive enzymes
• C. To absorb nutrients
• D. To neutralize stomach acid

Correct answer: A

Rationale: Rationale: The gallbladder is a small organ located beneath the liver that plays a crucial role in the digestive system. Its main function is to store and concentrate bile, a digestive fluid produced by the liver. Bile is released from the gallbladder into the small intestine to help with the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, allowing it to be released in a controlled manner when needed to aid in the digestion of fatty foods. Therefore, option A is the correct answer as it accurately describes the main function of the gallbladder.
