1. Which type of nuclear force is responsible for holding protons and neutrons together in the nucleus of an atom?

• A. Electromagnetism
• B. Gravity
• C. Strong nuclear force
• D. Weak nuclear force

Correct answer: C

Rationale: The incredibly powerful, strong nuclear force overcomes the repulsive electrostatic force between protons, binding them together and stabilizing the nucleus.

2. She notes that there is an increasing unrest of the staff due to fatigue brought about by

• A. Evaluate the overall result of the unrest
• B. Initiate a group interaction
• C. Develop a plan and implement it
• D. Identify external and internal forces.

Correct answer: C

Rationale: The correct answer is C: 'Develop a plan and implement it.' In the given scenario, the staff is experiencing unrest due to fatigue, which is a serious issue affecting their well-being and productivity. By developing a plan to address the fatigue issue and implementing it effectively, the organization can provide necessary support to the staff, improve working conditions, and enhance overall morale and performance. This proactive approach is crucial in maintaining a healthy work environment and ensuring the well-being of the staff members. Options A, B, and D do not directly address the root cause of fatigue and unrest among the staff, making them less suitable answers.

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

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: b

Rationale: Weight is the measure of the force of gravity acting on an object. It is calculated as mass multiplied by the acceleration due to gravity.

4. What happens to the kinetic energy of an object when its velocity is doubled?

• A. Kinetic energy remains the same
• B. Kinetic energy is halved
• C. Kinetic energy doubles
• D. Kinetic energy quadruples

Correct answer: c

Rationale: Kinetic energy is directly proportional to the square of an object's velocity.

5. Which part of the brain is responsible for regulating heart rate, breathing, and swallowing?

• A. Cerebrum
• B. Cerebellum
• C. Medulla oblongata
• D. Thalamus

Correct answer: C

Rationale: The correct answer is C: Medulla oblongata. The medulla oblongata is located at the base of the brainstem and is responsible for regulating essential functions such as heart rate, breathing, and swallowing. It contains vital control centers for these automatic processes, making it a critical part of the brain for maintaining life. The cerebrum is primarily involved in higher brain functions such as thinking and voluntary movement, while the cerebellum helps with coordination and balance. The thalamus acts as a relay station for sensory information. Therefore, the medulla oblongata is the most appropriate choice for regulating these basic physiological functions.

6. The "master gland" of the endocrine system, located at the base of the brain, secretes various hormones that control other glands is the:

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

Correct answer: B

Rationale: The correct answer is B: Pituitary gland. The pituitary gland is often referred to as the "master gland" because it plays a crucial role in regulating other endocrine glands in the body. It is located at the base of the brain and secretes various hormones that control functions such as growth, metabolism, reproduction, and stress response. The thyroid gland (A) regulates metabolism, the adrenal gland (C) produces hormones involved in stress response, and the pancreas (D) is primarily responsible for regulating blood sugar levels through insulin production, but they do not serve as the master gland of the endocrine system.
