Anatomy

1. The adaptive immune system develops a targeted response to specific pathogens. What type of immune cell is responsible for producing antibodies?

Correct answer: D

Rationale: The correct answer is D: B cells. B cells are a type of lymphocyte responsible for producing antibodies, which play a crucial role in the adaptive immune response. When a pathogen enters the body, B cells are activated and differentiate into plasma cells that secrete specific antibodies to target and neutralize the pathogen. Natural killer cells (A) are part of the innate immune system and are responsible for killing infected or abnormal cells. Phagocytes (B) are another type of innate immune cell that engulfs and digests pathogens. Helper T cells (C) play a vital role in coordinating the immune response but do not directly produce antibodies.

2. What is the relationship between mass and inertia?

Correct answer: a

Rationale: Mass is a measure of the amount of matter in an object and is directly related to its inertia.

3. The energy released during a chemical reaction is called:

Correct answer: D

Rationale: Exothermic means "outward heat," indicating energy is released during the reaction.

4. What property of a substance remains constant regardless of changes in its shape or size?

Correct answer: a

Rationale: Mass remains constant regardless of changes in an object's shape or size.

5. Which part of the brain generates the rhythmic electrical activity responsible for brain waves?

Correct answer: D

Rationale: The correct answer is D: Reticular formation. The reticular formation is a network of neurons located in the brainstem that plays a crucial role in regulating consciousness and sleep-wake cycles. It generates the rhythmic electrical activity responsible for brain waves, which are measured by an electroencephalogram (EEG). While the cerebrum, thalamus, and hypothalamus are important parts of the brain, they do not directly generate brain waves like the reticular formation does. Understanding the specific functions of different brain regions is crucial for comprehending how the brain functions and regulates various physiological processes.

6. Which sentence uses the word "literally" correctly?

Correct answer: B

Rationale: Option B uses "literally" to emphasize the magnitude of work, not to exaggerate a simple action.
