Biology

1. What is the main function of the epiglottis?

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.

2. What is the scientific study of the relationships between organisms and their environment?

Correct answer: C

Rationale: Rationale: A) Zoology is the scientific study of animals. B) Botany is the scientific study of plants. C) Ecology is the scientific study of the relationships between organisms and their environment, including the interactions between living organisms and their physical surroundings. D) Genetics is the scientific study of genes, heredity, and variation in living organisms, which is not directly related to the relationships between organisms and their environment.

3. A group of antibiotics that target the cell wall of bacteria are classified as:

Correct answer: A

Rationale: Rationale: Penicillins are a group of antibiotics that target the cell wall of bacteria by inhibiting the synthesis of peptidoglycan, a key component of the bacterial cell wall. By interfering with cell wall synthesis, penicillins weaken the cell wall, leading to bacterial cell lysis and death. This mechanism of action makes penicillins effective against a wide range of bacteria, particularly Gram-positive bacteria. Tetracyclines (B), Macrolides (C), and Fluoroquinolones (D) have different mechanisms of action and do not specifically target the bacterial cell wall. Tetracyclines inhibit protein synthesis, Macrolides interfere with bacterial ribosomes, and Fluoroquinolones target bacterial DNA gyrase and topoisomerase IV.

4. What is the scientific name for the tear gland?

Correct answer: A

Rationale: The lachrymal gland is the almond-shaped gland located above each eye, responsible for producing tears. Tears are a complex mixture of water, electrolytes, proteins, and other substances that help lubricate and protect the eyes from dryness and irritation.

5. As a manager, she focuses her energy on both the quality of services rendered to the patients

Correct answer: B

Rationale: The correct answer is 'B: Organization man management.' This type of management focuses on maintaining the efficiency and structure of an organization. In this scenario, the manager's emphasis on the quality of services aligns with the principles of organization man management, which prioritizes the coordination of tasks and resources to achieve optimal results within the organization. This contrasts with 'Country club management,' which emphasizes employee satisfaction over task accomplishment; 'Team management,' which focuses on collaboration and teamwork; and 'Authority-obedience management,' which centers on strict hierarchical control. Therefore, the most appropriate choice is 'B: Organization man management.'

6. The pH scale is used to indicate the concentration of:

Correct answer: A

Rationale: The pH scale measures the concentration of hydrogen ions in a solution, indicating acidity or basicity.
