1. A pencil measures 8cm long. What is this in mm?

• A. 80 mm
• B. 800 mm
• C. 8 mm
• D. 0.8 mm

Correct answer: A

Rationale: To convert centimeters to millimeters, you need to multiply by 10 since 1 centimeter is equal to 10 millimeters. Therefore, 8 cm x 10 mm/cm = 80 mm. The pencil measures 8 cm, which is equivalent to 80 mm when converted. Choice A is correct as it correctly converts 8 cm to mm by multiplying it by 10. Choices B, C, and D are incorrect because they do not apply the correct conversion factor.

2. Which is another name for thiamine?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B6
• D. Vitamin D

Correct answer: A

Rationale: Thiamine is another name for Vitamin B1. It is an essential vitamin that plays a crucial role in energy metabolism and is important for the proper functioning of the nervous system. Vitamin B2 is riboflavin, not thiamine. Vitamin B6 is pyridoxine, not thiamine. Vitamin D is a different vitamin responsible for calcium absorption and bone health, not thiamine. Therefore, the correct answer is Vitamin B1.

3. When a dielectric material is inserted between the plates of a charged capacitor, what will happen to the capacitance?

• A. Increase
• B. Decrease
• C. Remain the same
• D. Become unpredictable

Correct answer: A

Rationale: When a dielectric material is inserted between the plates of a charged capacitor, the capacitance will increase. This is because the presence of a dielectric material reduces the electric field between the plates, allowing more charge to be stored for a given voltage, thus increasing the capacitance. Choice B is incorrect because adding a dielectric material increases capacitance. Choice C is incorrect because capacitance changes when a dielectric is added. Choice D is incorrect because the effect of a dielectric on capacitance is predictable.

4. What is the main function of the ribosomes in the cell?

• A. DNA Replication
• B. Protein Synthesis
• C. Lipid Breakdown
• D. Cell Division

Correct answer: B

Rationale: The correct answer is B: Protein Synthesis. Ribosomes are cellular organelles responsible for synthesizing proteins. This process is crucial for various cellular functions. Choice A, DNA Replication, is incorrect as ribosomes are not involved in this process. Choice C, Lipid Breakdown, is also incorrect as ribosomes do not play a role in lipid metabolism. Choice D, Cell Division, is incorrect as ribosomes are not directly involved in the process of cell division.

5. If a patient has SALLOW skin, what is true?

• A. Her skin has a yellow tint
• B. Her skin has a blue tint
• C. Her skin has a red tint
• D. Her skin has a green tint

Correct answer: A

Rationale: Sallow skin is a term used to describe skin that appears yellowish in color. This discoloration can be due to various factors, such as an underlying health condition, poor circulation, or certain medications. Observing sallow skin can be an important clinical indicator that prompts further investigation into the patient's overall health status. Choice B, blue tint, is incorrect as sallow skin is not associated with a blue color. Choice C, red tint, and Choice D, green tint, are also incorrect as sallow skin specifically refers to a yellowish complexion, not red or green.
