1. Which of the following is NOT a characteristic of living organisms?

• A. Made up of cells
• B. Able to reproduce
• C. Require energy
• D. Non-motile

Correct answer: D

Rationale: A) Made up of cells: All living organisms are composed of one or more cells, a fundamental characteristic of life as defined by cell theory. B) Able to reproduce: Reproduction is a key characteristic of living organisms to pass on genetic information. C) Require energy: Energy is essential for carrying out life processes like growth and maintenance of homeostasis. D) Non-motile: While some living organisms are non-motile, movement is common in many organisms for survival activities like finding food, escaping predators, and responding to the environment. Therefore, being non-motile is not a universal characteristic of living organisms, making it the correct answer in this context.

2. What is a characteristic property of acids?

• A. Bitter taste
• B. Sour taste
• C. Slippery feel
• D. Sweet taste

Correct answer: B

Rationale: The correct characteristic property of acids is a sour taste. Acids release hydrogen ions when dissolved in water, giving them a sour taste. Bitter taste is a property associated with bases, not acids. Slippery feel is a characteristic property of bases, due to their soap-like nature. Sweet taste does not accurately describe the characteristic property of acids, as they are known for their sour taste.

3. What is the name of the master gland that regulates the function of many other endocrine glands?

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

Correct answer: B

Rationale: The pituitary gland is commonly referred to as the master gland because it controls the functions of numerous other endocrine glands in the body. It secretes various hormones that are essential for regulating processes like growth, metabolism, reproduction, and stress response. The thyroid gland (Choice A) primarily regulates metabolism and does not oversee other endocrine glands. The hypothalamus (Choice C) plays a role in regulating the pituitary gland but is not the master gland. The adrenal gland (Choice D) produces hormones related to stress response but is not considered the master gland that regulates other endocrine glands.

4. Which of the following nutrients is essential for muscle growth and repair?

• A. Vitamin C
• B. Protein
• C. Carbohydrates
• D. Fat

Correct answer: B

Rationale: Protein is essential for muscle growth and repair as it provides the necessary building blocks (amino acids) for muscle tissue synthesis and repair. While vitamins and minerals are crucial for overall health, protein has a specific role in muscle development. Carbohydrates supply energy for workouts, and fats are important for general health but are less directly involved in muscle growth and repair compared to protein.

5. Which part of the hair is not attached to the follicle?

• A. Bulb
• B. Root
• C. Shaft
• D. Strand

Correct answer: C

Rationale: The correct answer is C, 'Shaft.' The hair shaft is the part of the hair that extends above the skin surface and is not attached to the follicle. The bulb and root are parts that are connected to the follicle as they are located below the skin surface and play a role in hair growth. The strand, on the other hand, refers to a single hair fiber and is not a distinct part of the hair anatomy.
