1. Which type of cartilage allows for smooth movement at joints and absorbs shock?

Correct answer: B

Rationale: Fibrocartilage is the correct answer. It is found in areas requiring both support and resilience, such as the intervertebral discs and knee joints. Fibrocartilage contains collagen fibers for strength and proteoglycans for resilience, making it suitable for functions that involve smooth movement at joints and shock absorption. Hyaline cartilage, while providing structural support, is not primarily responsible for smooth movement and shock absorption. Elastic cartilage is more flexible and is found in locations like the ear and epiglottis, but it is not known for its shock-absorbing properties. Choosing 'None of the above' disregards the correct option of fibrocartilage, which is specifically designed for the functions described in the question.

2. What is 0.5 liters in milliliters?

Correct answer: B

Rationale: 0.5 liters is equivalent to 500 milliliters. To convert liters to milliliters, you multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, the correct answer is 500 ml (0.5 * 1000 = 500). Choices A, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters.

3. What property of a substance measures the amount of matter per unit volume?

Correct answer: C

Rationale: Density is the property of a substance that measures the amount of matter per unit volume. It is calculated by dividing the mass of an object by its volume. Mass refers to the amount of matter in an object, weight is the force of gravity acting on an object, and volume is the amount of space an object occupies. Therefore, in this context, density is the correct answer as it specifically relates to the concentration of matter within a given volume.

4. What is the difference between DNA and RNA?

Correct answer: B

Rationale: A) Incorrect. DNA is double-stranded, but RNA is typically single-stranded. B) Correct. DNA contains deoxyribose sugar, which lacks an oxygen atom on the 2' carbon of the sugar ring, while RNA contains ribose sugar, which has an additional hydroxyl group on the 2' carbon. C) Incorrect. RNA contains the nitrogenous base uracil, while DNA contains thymine. D) Incorrect. DNA and RNA have distinct structures and functions, so they are not identical molecules.

5. Which of the following suffixes denotes a state or quality?

Correct answer: B

Rationale: The suffix "-ness" indicates a state or quality, as seen in words like "happiness" (the state of being happy). Choice A, "-ic," typically denotes characteristics or qualities, such as in "heroic." Choice C, "-ous," often signifies the presence of a quality or relationship, like in "poisonous." Choice D, "-ful," usually means full of or characterized by, as in "beautiful." Therefore, the correct answer is B because it best fits the description of indicating a state or quality.
