1. Define work in physics.

• A. Force applied to an object at rest
• B. Force exerted by an object in motion
• C. Transfer of energy through motion along a direction
• D. Measure of an object's potential energy

Correct answer: c

Rationale: Work in physics is the transfer of energy when a force is applied and the object moves in the direction of the force.

2. Harry is a Unit Manager I the Medical Unit. He is not satisfied with the way things are going

• 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

3. The muscular sac that stores urine until it is released from the body is called the:

• A. Urethra
• B. Bladder
• C. Ureter
• D. Nephron

Correct answer: B

Rationale: The correct answer is B: Bladder. The bladder is a muscular sac that stores urine until it is ready to be released from the body through the urethra. The urethra is the tube that carries urine from the bladder out of the body. Ureters are tubes that carry urine from the kidneys to the bladder. Nephrons are the functional units of the kidneys responsible for filtering the blood and producing urine. Therefore, the bladder is the specific organ responsible for storing urine until it is expelled from the body, making it the correct answer.

4. Which neurotransmitter is associated with pleasure, reward, and motivation, and is often implicated in conditions such as addiction?

• A. Acetylcholine
• B. Dopamine
• C. Serotonin
• D. GABA (Gamma-aminobutyric acid)

Correct answer: b

Rationale: The correct answer is B: Dopamine. Dopamine is a neurotransmitter that is commonly associated with pleasure, reward, and motivation. It plays a crucial role in the brain's reward system and is often implicated in conditions such as addiction. Dopamine is released in response to rewarding stimuli, reinforcing behaviors that lead to pleasure. Acetylcholine is involved in muscle contraction and memory, not pleasure and reward. Serotonin is known for regulating mood and emotions, while GABA is an inhibitory neurotransmitter that helps reduce neural activity. Therefore, dopamine is the neurotransmitter most closely linked to pleasure, reward, and motivation in the brain.

5. How does the potential energy of an object change when it is compressed?

• A. Potential energy decreases
• B. Potential energy increases
• C. Potential energy remains constant
• D. Potential energy becomes zero

Correct answer: b

Rationale: When an object is compressed, it stores potential energy due to its altered position or configuration.

6. What tool helps scientists identify and classify organisms based on their shared characteristics?

• A. Binomial nomenclature
• B. Cladistics
• C. Dichotomous key
• D. Domain-based classification

Correct answer: C

Rationale: Rationale: A) Binomial nomenclature is a system used to give each organism a two-part scientific name (genus and species) but does not help in identifying or classifying organisms based on shared characteristics. B) Cladistics is a method of classification based on evolutionary relationships and shared characteristics, but it is not a tool used for identifying organisms. C) Dichotomous key is a tool that helps scientists identify and classify organisms based on their shared characteristics by presenting a series of choices leading the user to the correct identification. D) Domain-based classification is a system of classification that groups organisms into three domains (Bacteria, Archaea, Eukarya) based on molecular and genetic similarities, but it is not a tool used for identifying organisms based on shared characteristics.
