1. Which part of the neuron receives incoming signals from other neurons and conducts them toward the cell body?

• A. Axon
• B. Dendrite
• C. Synapse
• D. Myelin sheath

Correct answer: b

Rationale: The correct answer is B: Dendrite. Dendrites are the part of the neuron that receive incoming signals from other neurons and conduct them toward the cell body. They play a crucial role in communication between neurons by receiving neurotransmitters released from neighboring neurons. Axons transmit signals away from the cell body, synapses are the junctions where neurons communicate with each other, and myelin sheath is a fatty insulation that surrounds and protects axons. Therefore, in this scenario, dendrites are specifically responsible for receiving and conducting incoming signals towards the cell body.

2. Which of the following is the smallest unit of matter?

• A. Molecule
• B. Atom
• C. Compound
• D. Element

Correct answer: B

Rationale: An atom is the fundamental building block of matter, while molecules are formed by the combination of atoms.

3. Which of the following is evidence that the controlling process is effective?

• A. The things that were planned are done
• B. Physicians do not complain.
• C. Employees are contended
• D. There is an increase in customer satisfaction rate.

Correct answer: A

Rationale: The correct answer is A: 'The things that were planned are done.' This is evidence that the controlling process is effective because it indicates that the organization is able to execute its plans successfully. When planned tasks and activities are completed as intended, it shows that the controlling function is ensuring that operations are on track and that deviations are being corrected. The completion of planned tasks also demonstrates that resources are being effectively utilized and that performance is being monitored and controlled. The other options do not directly relate to the effectiveness of the controlling process. Physicians not complaining, employees being contented, and an increase in customer satisfaction rate could be influenced by various factors and may not necessarily be solely attributed to the effectiveness of the controlling process.

4. What is the primary function of hair on the human body?

• A. Insulation
• B. Sensory perception
• C. Protection
• D. Vitamin D synthesis

Correct answer: A

Rationale: The primary function of hair on the human body is insulation. Hair acts as a protective layer to help regulate body temperature by trapping heat close to the skin. This insulation property is especially important in colder climates to prevent excessive heat loss from the body. While hair can also provide some level of protection from external elements and minor injuries, its main role is to insulate the body. Sensory perception is mainly attributed to nerve endings in the skin rather than hair. Vitamin D synthesis is primarily dependent on exposure to sunlight rather than hair. Therefore, option A, insulation, is the correct answer.

5. What term describes the point where parallel rays of light converge or appear to diverge from after passing through a lens or reflecting off a mirror?

• A. Aperture
• B. Focal length
• C. Refractive index
• D. Lens thickness

Correct answer: B

Rationale: The focal length is the term that describes the point where parallel rays of light converge or appear to diverge from after passing through a lens or reflecting off a mirror. It is a crucial parameter in optics and is used to determine the magnification and image formation in optical systems. The other options (A) Aperture, (C) Refractive index, and (D) Lens thickness are not directly related to the point where parallel rays of light converge or appear to diverge.

6. Which property of a substance refers to the force exerted on an object due to gravity?

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

Correct answer:

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