Anatomy

1. B cells in the immune system are responsible for:

Correct answer: B

Rationale: B cells in the immune system are responsible for producing antibodies specific to a pathogen. This is because B cells are a type of white blood cell that play a crucial role in the adaptive immune response. When a B cell encounters a specific pathogen, it differentiates into plasma cells that produce antibodies targeted against that particular pathogen. These antibodies then tag the pathogen for destruction by other immune cells. B cells do not directly attack and engulf pathogens like phagocytes, nor do they destroy infected body cells like cytotoxic T cells. Therefore, option B is the correct answer as it accurately reflects the primary function of B cells in the immune system.

2. What type of error occurs in the sentence "Everyone knew who the culprit was, except for me"?

Correct answer: B

Rationale: The phrase "except for me" modifies "everyone," but it is misplaced after the verb "knew," causing confusion.

3. What property of a substance refers to its ability to undergo a chemical change and form new substances with different properties?

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, forming new substances with different properties.

4. What is the periodic law?

Correct answer: A

Rationale: The periodic law states that the properties of elements are a periodic function of their atomic numbers. This means that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their properties. This forms the basis for the modern periodic table. Option B describes the periodic table itself, while options C and D do not accurately describe the periodic law.

5. What is the primary function of the myelin sheath that surrounds some axons in the nervous system?

Correct answer: c

Rationale: The primary function of the myelin sheath that surrounds some axons in the nervous system is to speed up the transmission of nerve impulses. The myelin sheath acts as an insulating layer, which helps nerve impulses travel faster along the axon by allowing them to 'jump' from one node of Ranvier to the next, a process known as saltatory conduction. This increases the efficiency and speed of signal transmission, enabling rapid communication within the nervous system. Therefore, option C is the correct answer as it accurately describes the role of the myelin sheath in enhancing the speed of nerve impulse transmission.

6. Muscle tissue is responsible for movement. Which type of muscle tissue is found in the heart?

Correct answer: C

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is a specialized type of muscle tissue found in the heart. Unlike skeletal muscle, which is under voluntary control, and smooth muscle, which is found in the walls of internal organs and blood vessels, cardiac muscle is involuntary and responsible for the rhythmic contractions of the heart to pump blood throughout the body. Therefore, cardiac muscle is the specific type of muscle tissue found in the heart, making it the correct choice for this question.
