1. What is the scientific name for the common housefly?

• A. Musca domestica
• B. Drosophila melanogaster
• C. Apis mellifera
• D. Anopheles gambiae

Correct answer: A

Rationale: Rationale: - Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. - Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. - Apis mellifera (option C) is the scientific name for the western honeybee. - Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

2. What is the relationship between work and kinetic energy?

• A. Work is the cause of kinetic energy
• B. Kinetic energy is the cause of work
• C. Work and kinetic energy are the same
• D. Work and kinetic energy are unrelated

Correct answer: a

Rationale: Work done on an object can change its kinetic energy, either increasing or decreasing it.

3. Which of the following is the main function of the liver?

• A. To produce bile, which helps digest fats
• B. To store energy in the form of glycogen
• C. To produce proteins that help to clot blood
• D. To detoxify harmful substances in the body

Correct answer: D

Rationale: Rationale: A) The liver does produce bile, which helps in the digestion of fats, but this is not its main function. Bile is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. B) While the liver does store energy in the form of glycogen, this is not its main function. Glycogen is a form of glucose storage that can be broken down into glucose when the body needs energy. C) The liver does produce proteins that help to clot blood, such as fibrinogen and prothrombin, but this is not its main function. These proteins are essential for the blood clotting process to prevent excessive bleeding. D) The main function of the liver is to detoxify harmful substances in the body. The liver processes and removes toxins, drugs, alcohol, and other harmful substances from the bloodstream, making them less harmful and

4. Which part of the neuron is responsible for transmitting signals away from the cell body and toward other neurons or muscles?

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

Correct answer: a

Rationale: The correct answer is 'A: Axon.' The axon is a long, slender projection of a neuron that carries nerve impulses away from the cell body towards other neurons or muscles. It acts as the primary transmission line of the nervous system, sending electrical signals known as action potentials. Dendrites, on the other hand, receive signals from other neurons and transmit them towards the cell body. The synapse is the junction between two neurons where communication occurs. The myelin sheath is a fatty substance that surrounds and insulates the axon, speeding up the transmission of nerve impulses. Therefore, the axon is specifically responsible for transmitting signals away from the cell body, making it the correct answer.

5. Which element is used in fire extinguishers to smother flames by displacing oxygen?

• A. Nitrogen
• B. Carbon dioxide
• C. Helium
• D. Argon

Correct answer: B

Rationale: Carbon dioxide extinguishes flames by depriving them of oxygen, preventing the chemical reaction that sustains the fire.

6. Kathleen knows that one of her staff is experiencing burnout. Which of the following is the

• A. Advise her staff to go on vacation.
• B. Ignore her observations; it will be resolved even without intervention
• C. Remind her to show loyalty to the institution.
• D. Let the staff ventilate her feelings and ask how she can be of help.

Correct answer: C

Rationale: The correct answer is C: 'Remind her to show loyalty to the institution.' When an employee is experiencing burnout, it is important for the supervisor to address the issue with compassion and support. Reminding the staff member to show loyalty to the institution can help them feel valued and appreciated, which can contribute to their overall well-being. This response emphasizes the importance of fostering a positive work environment and promoting a sense of belonging. Options A and B do not address the root cause of burnout and may not effectively support the staff member. Option D, while encouraging communication, does not address the loyalty aspect which can be crucial in improving morale and reducing burnout.
