1. What is the SI unit of measurement for work?

• A. Newton-meter (N·m)
• B. Joule (J)
• C. Watt (W)
• D. Meter per second (m/s)

Correct answer: b

Rationale: Work is measured in Joules (J) in the SI unit system.

2. Identify the adjective in the following sentence: The colorful sunset painted the sky with vibrant hues.

• A. sunset
• B. with
• C. colorful
• D. painted

Correct answer: C

Rationale: Adjectives modify nouns and pronouns. The adjective "colorful" describes the noun "sunset".

3. Which division of the peripheral nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, enabling voluntary muscle movements?

• A. Somatic nervous system
• B. Autonomic nervous system
• C. Sympathetic nervous system
• D. Parasympathetic nervous system

Correct answer: a

Rationale: The correct answer is A: Somatic nervous system. The somatic nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, allowing for voluntary muscle movements. This division controls conscious movements such as walking, talking, and picking up objects. The autonomic nervous system (option B) controls involuntary functions like heart rate and digestion, while the sympathetic (option C) and parasympathetic (option D) nervous systems are subcategories of the autonomic system and regulate the body's responses to stress and relaxation, respectively. Therefore, the somatic nervous system is the correct division responsible for voluntary muscle movements.

4. Which hormone, produced by the pituitary gland, stimulates the production of milk in mammary glands during breastfeeding?

• A. Growth hormone (GH)
• B. Thyroid-stimulating hormone (TSH)
• C. Prolactin
• D. Follicle-stimulating hormone (FSH)

Correct answer: c

Rationale: The correct answer is C: Prolactin. Prolactin is the hormone produced by the pituitary gland that stimulates the production of milk in the mammary glands during breastfeeding. It plays a crucial role in lactation by promoting the growth and development of the mammary glands and initiating the production of milk. Growth hormone (GH) regulates growth and metabolism, not milk production. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland, not mammary glands. Follicle-stimulating hormone (FSH) is involved in reproductive processes, not milk production. Therefore, prolactin is the hormone directly responsible for stimulating milk production during breastfeeding.

5. Tendonitis is an inflammation of the

• A. Muscles
• B. Tendons
• C. Ligaments
• D. Cartilage

Correct answer: B

Rationale: The correct answer is B: "Tendons." Tendonitis is a condition characterized by inflammation of the tendons, which are the tough bands of tissue that connect muscles to bones. This inflammation can result from overuse, injury, or aging. Muscles (Option A) are not typically inflamed in tendonitis, although they work in conjunction with tendons. Ligaments (Option C) connect bones to other bones and are not involved in tendonitis. Cartilage (Option D) is a smooth, flexible connective tissue that cushions joints and is not directly related to tendonitis.

6. Which law of motion states that for every action, there is an equal and opposite reaction?

• A. Newton's First Law
• B. Newton's Second Law
• C. Newton's Third Law
• D. Law of Universal Gravitation

Correct answer: c

Rationale: Newton's Third Law states the action-reaction principle.
