1. What is the medical term for an ingrown hair?

Correct answer: A

Rationale: The correct answer is A, Folliculitis. Folliculitis is the medical term for the inflammation of hair follicles, which can be caused by ingrown hairs. Hirsutism refers to excessive hair growth, pseudofolliculitis barbae is a condition where shaving causes ingrown hairs, and alopecia is hair loss. Therefore, choices B, C, and D are incorrect as they do not specifically refer to ingrown hairs.

2. Which fibrous connective tissue connects a muscle to a bone, allowing movement at a joint?

Correct answer: A

Rationale: Tendons, the correct answer, are fibrous connective tissues that connect muscles to bones, enabling movement at joints. They play a crucial role in transmitting the force generated by muscles to the bones, facilitating movement. Ligaments (option B) connect bone to bone, providing stability to joints. Cartilage (option C) is a flexible tissue that acts as a cushion, reducing friction between bones in joints. Bursae (option D) are fluid-filled sacs located near joints that help reduce friction between tissues such as tendons and bones.

3. Which of the following statements is true regarding a supersaturated solution?

Correct answer: A

Rationale: A supersaturated solution is unstable and tends to crystallize because it contains more solute than it could dissolve at a given temperature. This excess solute is in a metastable state and can precipitate out if disturbed, leading to the formation of crystals. Option B is incorrect because a supersaturated solution does contain more solute than it could normally dissolve, but it becomes unstable due to this excess solute. Option C is incorrect because while a supersaturated solution does have a higher concentration than a saturated solution, the defining characteristic related to its instability is the excess solute. Option D is incorrect as supersaturated solutions can be encountered in various everyday scenarios, such as certain sugar solutions used in cooking or rock candy production.

4. What is the law of conservation of energy?

Correct answer: C

Rationale: The correct answer is C: 'Energy can neither be created nor destroyed, only transformed from one form to another.' The law of conservation of energy is a fundamental principle in physics. It states that the total energy in a closed system remains constant over time. Energy can change from one form to another (e.g., potential energy to kinetic energy), but the total amount of energy remains the same. Choices A, B, and D are incorrect because they do not accurately represent the law of conservation of energy. Energy is not created or destroyed according to this law, but rather transformed.

5. What are the differences between RNA and DNA?

Correct answer: B

Rationale: A) This statement is incorrect. RNA and DNA have different structures and functions. RNA is involved in protein synthesis and other cellular processes, while DNA stores genetic information. B) This statement is correct. RNA is typically single-stranded, while DNA is double-stranded, forming a double helix structure. C) This statement is correct. RNA contains ribose sugar in its backbone, while DNA contains deoxyribose sugar. D) This statement is incorrect. RNA contains adenine, guanine, cytosine, and uracil, while DNA contains adenine, guanine, cytosine, and thymine. Choice B is the correct answer as it accurately describes one of the key differences between RNA and DNA, emphasizing their structural disparity in terms of single-strandedness for RNA and double-strandedness for DNA. Choices A, C, and D contain inaccuracies regarding the structural and compositional distinctions between RNA and DNA, making them incorrect choices.
