1. What is the function of the pituitary gland?

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. The network of vessels and ducts responsible for draining excess fluid and waste products from tissues is the:

Correct answer: C

Rationale: The correct answer is C: Lymphatic system. The lymphatic system is a network of vessels and ducts that play a crucial role in maintaining fluid balance in the body by draining excess fluid and waste products from tissues. Unlike the circulatory system (A), which primarily transports blood, the lymphatic system is specifically designed for this drainage function. The digestive system (B) is responsible for breaking down food and absorbing nutrients, while the respiratory system (D) is involved in the exchange of gases. Therefore, the lymphatic system is the correct answer for this question as it is uniquely tasked with managing tissue fluid balance and waste removal.

3. She came across a theory which states that the leadership style is effective dependent on the

Correct answer: A

Authoritarian leadership style emphasizes control and obedience, while laissez-faire leadership style lacks guidance and structure, and bureaucratic leadership style focuses on rules and regulations. Therefore, democratic leadership style is considered effective as it values the opinions and contributions of team members, leading to better outcomes and team cohesion.

4. What property of matter refers to the force of gravity acting on an object?

5. Which statement correctly describes the concept of ionization energy?

Correct answer: A

Rationale: The energy required to remove an electron from an outermost shell. Ionization energy varies depending on the element and electron configuration, indicating its difficulty to lose electrons and influencing its reactivity.

6. What is the main reason why elements in Group 18 (Noble gases) are generally unreactive?

Correct answer: C

Rationale: Noble gases have their outermost electron shells filled with 8 electrons, achieving a stable configuration with minimal urge to gain or lose electrons, making them less prone to chemical reactions.
