1. What do ligaments connect?

• A. Muscle to muscle
• B. Bone to bone
• C. Bone to muscle
• D. Muscle to tendon

Correct answer: B

Rationale: Ligaments are fibrous connective tissues that connect bone to bone, providing stability and support to joints. They help prevent excessive movement in the joints and maintain proper alignment between bones during movement. Ligaments are not directly involved in connecting muscle to muscle, bone to muscle, or muscle to tendon. Choice A is incorrect because ligaments do not connect muscle to muscle. Choice C is incorrect as ligaments do not connect bone to muscle. Choice D is incorrect as ligaments do not connect muscle to tendon.

2. What is the process by which lighter nuclei fuse to form heavier nuclei, releasing a large amount of energy?

• A. Fission
• B. Fusion
• C. Radioactivity
• D. Chain reaction

Correct answer: B

Rationale: Fusion is the process by which lighter nuclei combine to form heavier nuclei, releasing a large amount of energy in the process. This process is the source of energy in stars, including our Sun. Fission, the process of splitting heavier nuclei into lighter nuclei, is not correct. Radioactivity involves the emission of particles or radiation from the nucleus of an unstable atom, which is different from fusion. A chain reaction is a self-sustaining reaction where the products of one reaction cause further reactions, which is unrelated to fusion.

3. What is the author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air?

• A. To emphasize the adaptability and complexity of insect life cycles.
• B. To compare aquatic insects with those that remain airborne.
• C. To highlight the unique features of insects that live in both environments.
• D. To question the validity of studying insects that live in only one environment.

Correct answer: A

Rationale: The author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air is to emphasize the adaptability and complexity of insect life cycles. The author highlights how some insects transition between aquatic and aerial environments, showcasing the diverse strategies and features these insects possess to thrive in different habitats. Choice B is incorrect because the author is not solely comparing aquatic insects with those that remain airborne, but rather exploring their adaptability. Choice C is incorrect as the focus is not on highlighting unique features but on showcasing the transition between environments. Choice D is incorrect as the author is not questioning the validity of studying insects in only one environment but rather demonstrating the fascinating dual-life cycles of certain insects.

4. Which of the following substitutions best captures the meaning of the word 'obsequious' in the sentence: 'The young apprentice was obsequious to his master, always eager to please'?

• A. showing deference
• B. poorly dressed
• C. reserved
• D. aggressive

Correct answer: A

Rationale: The word 'obsequious' means excessively submissive or eager to please, often to the point of showing deference. In this context, 'showing deference' best captures the meaning, indicating respect or submission rather than being poorly dressed, reserved, or aggressive. 'Poorly dressed' (B) is unrelated to the meaning of obsequious. 'Reserved' (C) suggests a different behavior that is opposite to being obsequious. 'Aggressive' (D) is the opposite of obsequious and does not fit the context of the sentence.

5. How many bones are there in the adult human skeleton?

• A. 126
• B. 206
• C. 300
• D. 525

Correct answer: B

Rationale: The correct answer is B: 206. The adult human skeleton consists of 206 bones. These bones are categorized into the axial skeleton, which includes the skull, vertebral column, and rib cage, and the appendicular skeleton, comprising the bones of the limbs and girdles. Each bone has a specific function in providing structure and support to the body. Choices A, C, and D are incorrect because they do not represent the accurate number of bones in the adult human skeleton. It is essential to remember the correct number of bones in the human skeleton for a better understanding of the skeletal system.
