1. Ms. Valencia is responsible to the number of personnel reporting to her. This principle refers

• A. Span of control
• B. Unity of command
• C. Carrot and stick principle
• D. Esprit d’ corp

Correct answer: B

Rationale: The correct answer is B: Unity of command. Unity of command is a fundamental principle of management stating that each employee should receive orders from only one supervisor to avoid confusion and ensure clarity in the chain of command. In this scenario, Ms. Valencia's responsibility for the number of personnel reporting to her aligns with the concept of unity of command. Span of control refers to the number of subordinates a supervisor can efficiently manage, while the carrot and stick principle involves motivating employees through rewards and punishments. Esprit d’ corp refers to the sense of unity and camaraderie within a group.

2. Which biome is characterized by cold temperatures, permafrost, and coniferous trees?

• A. Tundra
• B. Desert
• C. Rainforest
• D. Savanna

Correct answer: A

Rationale: Rationale: A) Tundra: This biome is characterized by cold temperatures, permafrost (permanently frozen subsoil), and vegetation such as mosses, lichens, and coniferous trees like spruce and fir. The tundra is found in high latitudes near the Arctic Circle and high altitudes in mountainous regions. B) Desert: Deserts are characterized by low precipitation levels and high temperatures, with sparse vegetation adapted to arid conditions. C) Rainforest: Rainforests are characterized by high levels of rainfall, warm temperatures, and dense vegetation with a variety of plant and animal species. D) Savanna: Savannas are tropical grasslands with scattered trees and shrubs, characterized by a distinct wet and dry season. In this case, the description of cold temperatures, permafrost, and coniferous trees aligns most closely with the characteristics of the tundra biome, making option A

3. What is the main function of the epiglottis?

• A. To store bile
• B. To absorb nutrients
• C. To prevent food from entering the trachea
• D. To produce digestive enzymes

Correct answer: C

Rationale: Rationale: The epiglottis is a flap of cartilage located at the base of the tongue that covers the opening of the trachea during swallowing to prevent food and liquids from entering the airway. This action helps direct food and liquids into the esophagus, which leads to the stomach for digestion, while also protecting the respiratory system from potential blockages that could lead to choking or aspiration pneumonia. Options A, B, and D are incorrect as the epiglottis is not involved in storing bile, absorbing nutrients, or producing digestive enzymes.

4. What is the role of RNA in protein synthesis?

• A. Stores genetic information
• B. Decodes genetic information
• C. Provides energy for the process
• D. Transports amino acids to the ribosomes

Correct answer: B

Rationale: Rationale: RNA plays a crucial role in protein synthesis by decoding the genetic information stored in DNA and carrying it to the ribosomes where proteins are synthesized. This process involves transcription, where RNA is synthesized from DNA, and translation, where the information in RNA is used to assemble amino acids into proteins. RNA acts as a messenger between DNA and the ribosomes, ensuring that the correct sequence of amino acids is used to build proteins according to the genetic code. Therefore, option B is the most appropriate choice as it accurately describes the role of RNA in protein synthesis.

5. Which sentence uses the semicolon correctly?

• A. The play was long; however, it was very entertaining.
• B. The guests arrived; Sarah greeted them at the door.
• C. John likes apples; Mary prefers oranges.
• D. He was tired; he went to bed early.

Correct answer: B

Rationale: Option B joins two independent clauses related to the same event.

6. When writing dialogue, remember to:

• A. Avoid contractions and informal language for realism.
• B. Use formal vocabulary to sound sophisticated.
• C. Create realistic speech patterns reflecting the characters' personalities.

Correct answer: C

Rationale: Effective dialogue captures the characters' unique voices and personalities through realistic speech patterns and word choices.
