1. Which phase of the employment process includes getting on the payroll and completing

• A. Orientation
• B. Induction
• C. Selection
• D. Recruitment

Correct answer: D

Rationale: The correct answer is D: Recruitment. Recruitment is the phase of the employment process where organizations actively seek out and attract potential candidates for job openings. This involves advertising the position, sourcing candidates, and conducting initial screenings. Once the recruitment process is complete and a candidate has been selected, they move on to the selection phase. Orientation, on the other hand, occurs after a candidate has been hired and involves familiarizing the new employee with the organization, its policies, and their role. Induction is often used interchangeably with orientation and refers to the process of integrating a new employee into the organization. Therefore, in this context, recruitment is the most appropriate phase that involves getting on the payroll and completing the initial steps to bring a new employee on board.

2. The basic unit of communication in the nervous system is called a:

• A. Neuron
• B. Astrocyte
• C. Neurotransmitter
• D. Synapse

Correct answer: A

Rationale: The basic unit of communication in the nervous system is a neuron. Neurons are specialized cells that transmit information through electrical and chemical signals. They form complex networks to relay messages throughout the body. Astrocytes are support cells that help maintain the environment around neurons. Neurotransmitters are chemicals that transmit signals between neurons at synapses. A synapse is a junction between two neurons where communication occurs. However, the primary unit responsible for communication in the nervous system is the neuron, making it the correct answer.

3. 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.

4. An object is thrown upwards and reaches a maximum height. Which of the following statements is TRUE about its velocity and acceleration at the peak?

• A. Velocity is zero and acceleration is maximum upwards
• B. Velocity is maximum and acceleration is zero.
• C. Velocity is maximum and acceleration is maximum upwards.
• D. Velocity is zero and acceleration is maximum downwards.

Correct answer: A

Rationale: At the peak, the object momentarily stops moving (zero velocity), but gravity still pulls it upwards, causing a maximum upward acceleration.

5. The T wave on an ECG corresponds to:

• A. Atrial depolarization
• B. Ventricular depolarization
• C. Atrial repolarization
• D. Ventricular repolarization

Correct answer: D

Rationale: The T wave on an ECG corresponds to ventricular repolarization. During this phase, the ventricles are resetting electrically after contraction, preparing for the next heartbeat. Atrial depolarization is represented by the P wave, ventricular depolarization by the QRS complex, and atrial repolarization is typically hidden within the QRS complex. Therefore, option D, 'Ventricular repolarization,' is the correct choice when identifying the electrical activity represented by the T wave on an ECG.

6. Which element is used in jewelry due to its malleability and resistance to tarnish?

• A. Iron
• B. Copper
• C. Gold
• D. Silver

Correct answer: C

Rationale: Gold's properties make it ideal for crafting durable and aesthetically pleasing jewelry
