TEAS 7 science practice

1. The 'fight-or-flight' response is triggered by the hormone released from the:

A. Thyroid gland
B. Adrenal glands
C. Pituitary gland
D. Pancreas

Correct answer: B

Rationale: The 'fight-or-flight' response is triggered by the release of adrenaline (epinephrine) and norepinephrine from the adrenal glands. These hormones prepare the body to either confront or flee from a perceived threat or stressor. The adrenal glands are crucial in initiating this rapid physiological response. Choices A, C, and D are incorrect because the thyroid gland primarily regulates metabolism and energy levels, the pituitary gland controls other endocrine glands but does not directly trigger the 'fight-or-flight' response, and the pancreas is responsible for regulating blood sugar levels through insulin and glucagon, not for triggering the 'fight-or-flight' response.

2. Which of the following literary devices is present in the excerpt?

A. Personification
B. Synecdoche
C. Metaphor
D. Colloquialism

Correct answer: D

Rationale: The correct answer is 'D: Colloquialism'. Colloquialism is the use of informal, everyday language in writing or speaking. In the given excerpt, the dialogue is informal and reflects everyday speech, making it an example of colloquialism. Choice A, 'Personification', attributes human qualities to non-human entities, choice B, 'Synecdoche', represents a part of something to refer to the whole, and choice C, 'Metaphor', implies a comparison between two unrelated things. These choices do not accurately describe the literary device present in the excerpt, making them incorrect.

3. Which of the following statements would be LEAST relevant in a formal essay about artist Salvador Dalí?

A. Although his works are famed for their dream-like qualities, Dalí executed them with realism reminiscent of the Renaissance masters.
B. Salvador Dalí’s eccentricity extended beyond his artwork, affecting the strange public persona he created, which can be witnessed in his numerous television appearances.
C. I’ve always found Dalí’s painting The Persistence of Memory to be really disturbing for some reason.
D. Although Salvador Dalí is best known for his paintings, he also was active in cinema and collaborated with such filmmakers as Luis Bunuel and Alfred Hitchcock.

Correct answer: C

Rationale: Option C is subjective and personal, making it less suitable for a formal essay about Salvador Dalí. In formal writing, it is important to maintain objectivity and focus on factual information rather than personal opinions. Choices A, B, and D provide relevant information about Dalí, his artwork, and his collaborations, which are more appropriate for inclusion in a formal essay.

4. What are the moon-shaped white structures at the base of fingernails called?

A. Lunulae
B. Cuticle
C. Hyponychium
D. Matrix

Correct answer: A

Rationale: The correct answer is A: Lunulae. The moon-shaped white structures at the base of fingernails are known as lunulae. They are most prominent on the thumb and are situated at the base of the nail matrix. The lunula is the visible part of the nail matrix, which is responsible for generating new nail cells. Choice B, Cuticle, is incorrect as it refers to the thin layer of skin at the base of the nail plate. Choice C, Hyponychium, is incorrect as it is the skin that lies beneath the free edge of the nail. Choice D, Matrix, is incorrect as it is the area where the nail is formed, located under the cuticle.

5. Define the term 'velocity' in relation to motion.

A. Speed in a specific direction
B. Distance traveled in a given time
C. Rate of change of position
D. Acceleration due to gravity

Correct answer: A

Rationale: Velocity is a vector quantity that describes the speed of an object along with its direction of motion. Unlike speed, which is a scalar quantity focusing solely on the magnitude of motion, velocity considers both speed and direction. Therefore, the best definition of velocity is 'speed in a specific direction.' Choice B, 'Distance traveled in a given time,' is incorrect as it defines speed rather than velocity. Choice C, 'Rate of change of position,' is more aligned with the definition of velocity but lacks the specificity of direction. Choice D, 'Acceleration due to gravity,' is unrelated to the definition of velocity and refers to a different concept in physics.
