1. A syringe holds 3ml of liquid. How many syringes are needed to measure 15ml of liquid?

• A. 3
• B. 5
• C. 7
• D. 9

Correct answer: B

Rationale: Since each syringe holds 3ml of liquid, to measure 15ml of liquid, you would need to divide 15ml by 3ml/syringe. This calculation gives you 5 syringes needed to measure 15ml of liquid. Choice A (3 syringes) is incorrect because 3 syringes would only hold 9ml of liquid, not 15ml. Choice C (7 syringes) and Choice D (9 syringes) are incorrect as they would result in an excess amount of liquid, which is not needed.

2. Select the meaning of the word in the sentence: 'The dog developed bilateral weakness in its hindquarters.'

• A. Present on two sides
• B. Available for exercise
• C. Affecting the left side
• D. Affecting the right side

Correct answer: A

Rationale: "Bilateral" refers to something that affects or involves both sides of the body, making "Present on two sides" the correct answer. The other options refer to one-sided or unrelated conditions.

3. The apical side of an epithelial cell:

• A. Is exposed to fluid or air
• B. Is on the bottom side of the cell
• C. Does not allow any substances to pass through
• D. None of the above

Correct answer: A

Rationale: The apical side of an epithelial cell is the top side, which is typically exposed to fluids, air, or the inside of an organ. This side allows substances to pass through it, facilitating the absorption, secretion, or excretion of various substances. Choice B is incorrect as the apical side is not on the bottom but the top side. Choice C is incorrect as the apical side does allow substances to pass through. Choice D is incorrect as there are characteristics associated with the apical side.

4. Calculate the product of (99)(0.56) =

• A. 99.30
• B. 99.56
• C. 55.44
• D. 199.54

Correct answer: C

Rationale: To find the product of 99 and 0.56, multiply the two numbers: 99 x 0.56 = 55.44. Therefore, the correct answer is 55.44.

5. What organelle do plant cells have that functions as storage, waste disposal, and protection?

• A. Nucleus
• B. Mitochondria
• C. Vacuoles
• D. Ribosomes

Correct answer: C

Rationale: Correct! Plant cells have vacuoles that serve as storage centers, help in waste disposal by containing and isolating harmful materials, and contribute to protection by storing toxic substances. The other choices are incorrect because the nucleus contains genetic material, mitochondria are responsible for energy production, and ribosomes are involved in protein synthesis.
