1. What is the formula for calculating molarity?

• A. M = n/V
• B. M = n/L
• C. M = mol/L
• D. M = mol/dm³

Correct answer: a

Rationale: All of these choices are equivalent to the original formula. The symbol "n" represents the number of moles of solute, and the symbol "V" represents the volume of the solution in liters. The symbol "L" is an abbreviation for "liters," and "dm³" is an alternative way to represent liters.

It contains the vocal cords, which vibrate as air passes through, producing sound. The trachea (A) is the windpipe that carries air to and from the lungs. The bronchi (C) are the main airways that branch off from the trachea into the lungs. The alveoli (D) are tiny air sacs in the lungs where gas exchange occurs, but they are not directly involved in vocalization.

• A. Call for a staff meeting and take this up in the agenda.
• B. Seek help from her manager.
• C. Develop a strategic action on how to deal with these concerns.
• D. Ignore the issues since these will be resolved naturally.

Correct answer: A

Rationale: Choosing option A, 'Call for a staff meeting and take this up in the agenda,' is the best course of action for Harry as a Unit Manager. By calling for a staff meeting, Harry can openly address his concerns with the team, gather input from team members, and work collaboratively to find solutions. This approach promotes transparency, communication, and teamwork, which are essential in resolving issues within a unit. Seeking help from his manager, as suggested in option B, may be necessary in some cases, but initiating a discussion with the staff first allows for a more inclusive problem-solving process. Developing a strategic action, as in option C, is important, but involving the team in this process through a staff meeting is crucial for buy-in and implementation. Ignoring the issues, as in option D, is never a productive approach as unresolved issues can escalate and impact team morale and performance. Therefore, option A is the most effective and proactive way for Harry to address hi

6. Inhalation

• A. Expiration
• B. Respiration
• C. Aspiration
• D. Aspiration

Correct answer: B

Rationale: The correct answer is B: 'Respiration.' Inhalation refers to the process of breathing in air, while respiration is the overall process of gas exchange in the body, including both inhalation and exhalation. Expiration refers specifically to the process of breathing out air. Aspiration, on the other hand, refers to the act of inhaling foreign objects into the lungs, which can be harmful. Therefore, 'Respiration' is the most appropriate term related to 'Inhalation' as it encompasses the entire process of breathing and gas exchange in the body.
