1. A physician prescribes a drug to help control a person's anxiety attacks. This drug most likely targets the

Correct answer: A

Rationale: The correct answer is A: Amygdala. The amygdala is a key brain structure involved in the processing of emotions, including anxiety. Medications for anxiety disorders often target the amygdala to help regulate emotional responses and control anxiety attacks. The amygdala plays a crucial role in the brain's fear circuit and is essential for the appropriate response to stress and threat perception. Choices B, C, and D are incorrect because the parietal lobe is primarily involved in sensory processing and spatial reasoning, the hypothalamus regulates basic functions like hunger, thirst, and body temperature, and sensory neurons transmit signals from sensory receptors to the central nervous system, none of which are directly related to the regulation of anxiety attacks.

2. Which cavity contains all of the frontal cavities? Choose only ONE best answer.

Correct answer: D

Rationale: The correct answer is D: Ventral. The ventral cavity includes both the thoracic and abdominopelvic cavities. The frontal cavities are part of the ventral cavity, which is located towards the front of the body, while the dorsal cavity is towards the back. The dorsal cavity contains the cranial and vertebral cavities, not the frontal cavities. The thoracic cavity is part of the ventral cavity but does not encompass all the frontal cavities. The abdominopelvic cavity is also part of the ventral cavity, but it does not include all of the frontal cavities. Therefore, the ventral cavity is the correct choice as it encompasses all the frontal cavities.

3. What is the measure of the total amount of space occupied by an object?

Correct answer: D

Rationale: Volume is the measure of the total amount of space occupied by an object. Mass refers to the amount of matter in an object, density is the mass per unit volume, and weight is the force of gravity acting on an object. When determining the space occupied by an object, volume is the appropriate measurement to consider. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not directly indicate the total amount of space occupied by an object. Mass, density, and weight are relevant in different contexts and measurements compared to volume.

4. What is the term for the ability of a substance to dissolve in another substance?

Correct answer: A

Rationale: Solubility is the property that describes the ability of a substance to dissolve in another substance. When a substance is soluble in another, it means it can form a homogeneous solution by dispersing at a molecular level within the solvent. Miscibility, on the other hand, refers to the ability of two liquids to mix and form a homogeneous solution. Immiscibility indicates the inability of substances to mix to form a homogeneous solution. Reactivity pertains to the ability of a substance to undergo chemical reactions, which is distinct from the concept of solubility.

5. What is the primary function of the circulatory system?

Correct answer: B

Rationale: The correct answer is B: To transport oxygen and nutrients. The primary function of the circulatory system is to deliver oxygen and essential nutrients to cells throughout the body and remove waste products like carbon dioxide. Choice A is incorrect as regulating body temperature is primarily the function of the body's thermoregulatory system. Choice C is incorrect as fighting infection is mainly the role of the immune system. Choice D is incorrect as breaking down waste is primarily handled by the digestive system.
