1. Which of the following is the main function of the stomach?

• A. To store food and break it down into smaller pieces
• B. To absorb nutrients into the bloodstream
• C. To produce enzymes that help digest food
• D. To eliminate waste products from the body

Correct answer: A

Rationale: Rationale: The main function of the stomach is to store food that has been ingested and mechanically break it down into smaller pieces through the process of churning and mixing with gastric juices. This mechanical breakdown, along with the action of stomach acid and enzymes, helps to initiate the digestion of food before it moves on to the small intestine for further digestion and absorption of nutrients. Absorption of nutrients into the bloodstream primarily occurs in the small intestine, not the stomach. The production of enzymes that help digest food primarily occurs in the pancreas and small intestine, not the stomach. The elimination of waste products from the body primarily occurs through the large intestine and rectum, not the stomach.

2. The "master gland" of the endocrine system, located at the base of the brain, secretes various hormones that control other glands is the:

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B: Pituitary gland. The pituitary gland is often referred to as the "master gland" because it plays a crucial role in regulating other endocrine glands in the body. It is located at the base of the brain and secretes various hormones that control functions such as growth, metabolism, reproduction, and stress response. The thyroid gland (A) regulates metabolism, the adrenal gland (C) produces hormones involved in stress response, and the pancreas (D) is primarily responsible for regulating blood sugar levels through insulin production, but they do not serve as the master gland of the endocrine system.

3. Which of the following factors would NOT affect the solubility of a solid solute in a liquid solvent?

• A. Temperature
• B. Pressure
• C. Particle size
• D. Nature of the solute and solvent

Correct answer: b

Rationale: Pressure does not significantly affect the solubility of solid solutes in liquid solvents. The other choices are factors that can influence solubility.

4. She finds out that some managers have benevolent-authoritative style of management. Which

• A. Have condescending trust and confidence in their subordinates
• B. Gives economic or ego awards
• C. Communicates downward to the staff
• D. Allows decision making among subordinates

Correct answer: D

Rationale: The correct answer is D because the benevolent-authoritative style of management involves allowing decision-making among subordinates. This style combines a caring attitude towards employees with a level of authority and control. Managers who adopt this style often empower their subordinates to make decisions within a set framework, fostering a sense of autonomy and responsibility among the team. Options A, B, and C do not accurately describe the characteristics of a benevolent-authoritative management style, making them incorrect choices for this question.

5. The external body covering, providing protection and contributing to temperature regulation, is composed of:

• A. Muscle tissue
• B. Epithelial tissue (skin)
• C. Bone marrow
• D. Cartilage

Correct answer: B

Rationale: The correct answer is B: Epithelial tissue (skin). The skin is the external body covering that provides protection against physical, chemical, and biological factors. It also plays a crucial role in regulating body temperature by controlling heat exchange with the environment through processes like sweating and blood vessel constriction or dilation. Muscle tissue (option A) is responsible for movement, bone marrow (option C) produces blood cells, and cartilage (option D) is a type of connective tissue found in joints. Therefore, epithelial tissue (skin) is the most suitable option as it directly addresses the functions of the external body covering.

6. What is the acceleration due to gravity near the Earth's surface?

• A. 9.8 meters per second squared (m/s²)
• B. 6.3 meters per second squared (m/s²)
• C. 5.0 meters per second squared (m/s²)
• D. 12.5 meters per second squared (m/s²)

Correct answer: a

Rationale: The acceleration due to gravity near the Earth's surface is approximately 9.8 m/s²
