1. Which of the following terms refers to the ability to detect and respond to changes in the internal and external environment?

• A. Growth
• B. Responsiveness
• C. Reproduction
• D. Development

Correct answer: B

Rationale: Responsiveness is the correct term that refers to the ability to detect and respond to changes in the internal and external environment. In this context, growth is incorrect as it pertains to an increase in size or number, reproduction involves producing offspring, and development refers to the process of growth, maturation, and differentiation of cells and tissues. Therefore, 'Responsiveness' is the most appropriate term for the given description.

2. Which of the following glands produces hormones that regulate metabolism?

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

Correct answer: C

Rationale: The thyroid gland is responsible for producing hormones that play a crucial role in regulating metabolism. One of the key hormones produced by the thyroid gland is thyroxine, which directly influences the body's metabolic rate. Therefore, the correct answer is the thyroid gland. The adrenal gland produces hormones like adrenaline, which are associated with the stress response and not primarily metabolic regulation. The pituitary gland regulates various other hormones but is not primarily responsible for metabolic regulation. The liver has a role in metabolism, mainly in processes like detoxification and nutrient storage, but it is not a gland that primarily produces hormones for metabolic regulation, making it an incorrect choice in this context.

3. In which group of the periodic table are alkali metals located?

• A. Group 1
• B. Group 2
• C. Group 7
• D. Group 8

Correct answer: A

Rationale: Alkali metals, such as lithium, sodium, and potassium, are located in Group 1 of the periodic table. This group is known for its highly reactive properties, low melting points, and the tendency to form alkaline solutions when they react with water. Group 2 consists of alkaline earth metals and not alkali metals, making choice B incorrect. Group 7 includes halogens, while Group 8 includes noble gases. These groups do not contain alkali metals, so choices C and D are also incorrect. Therefore, the correct answer is Group 1.

4. Which part of the respiratory system is responsible for gas exchange between the blood and inhaled air?

• A. Trachea
• B. Larynx
• C. Alveoli
• D. Pharynx

Correct answer: C

Rationale: The correct answer is C, Alveoli. The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place between the air we breathe in and the blood. The trachea, larynx, and pharynx are all part of the airway passage but do not directly participate in gas exchange. The trachea serves as the windpipe, the larynx is involved in sound production and protecting the airway during swallowing, and the pharynx helps with swallowing and speech production. Therefore, the alveoli specifically facilitate the critical gas exchange process, making them the correct answer in this context.

5. Classifications of human tissues exclude:

• A. Epithelial tissue
• B. Nervous tissue
• C. Adipose tissue (a specialized form of connective tissue)
• D. Bony tissue

Correct answer: D

Rationale: The correct answer is D: Bony tissue. Classifications of human tissues typically include epithelial tissue, nervous tissue, and connective tissue types such as adipose tissue. Bony tissue, also known as bone tissue, is a specialized form of connective tissue that provides structural support and protection for the body. Therefore, it is not excluded from classifications of human tissues. Choices A, B, and C are valid types of human tissues and are correctly included in classifications of human tissues.
