1. What is the function of the pituitary gland?

• A. Produces hormones that regulate growth and metabolism
• B. Filters blood and removes waste products
• C. Stores and releases bile
• D. Produces red blood cells

Correct answer: A

Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

2. Which of the following is NOT a major division of the nervous system?

• A. Peripheral nervous system
• B. Central nervous system
• C. Somatic nervous system
• D. Autonomic nervous system

Correct answer: C

Rationale: The somatic nervous system is actually a component of the peripheral nervous system, responsible for voluntary control of skeletal muscles and sensory information. The major divisions of the nervous system are the central nervous system (which includes the brain and spinal cord) and the peripheral nervous system (which includes all nerves outside the central nervous system). The autonomic nervous system, on the other hand, is a division of the peripheral nervous system responsible for involuntary functions like heart rate and digestion. Therefore, the correct answer is C, the somatic nervous system, as it is not a major division of the nervous system.

3. Identify the adverb in the following sentence: The patient waited anxiously for the doctor's news.

• A. waited

4. Balance the chemical equation: C4H10 + O2 → CO2 + H2O. What is the coefficient for oxygen?

• A. 5
• B. 6
• C. 7

5. The process by which a solid changes directly into a liquid is called:

• A. Melting
• B. Condensation
• C. Sublimation
• D. Deposition

Rationale: While melting is a solid to liquid transition, deposition, also known as sublimation, refers to a gas directly changing into a solid.

6. A lampshade consists of a cylindrical base (diameter 20cm, height 10cm) and a hemispherical top (same diameter as the base). What is its total surface area?

• A. 785 sq cm
• B. 1130 sq cm
• C. 1570 sq cm
• D. 2055 sq cm

Correct answer: D

Rationale: Calculate the surface area of the cylinder (base + lateral surface) and the hemisphere (half of a sphere's surface area). Add both areas to find the total surface area.
