TEAS Practice Test Science

Correct Answer: B

Rationale: The correct answer is B: Larynx. The larynx houses the vocal cords, which vibrate to produce sound for voice production. The pharynx is involved in swallowing, the trachea is responsible for air passage to the lungs, and the bronchi are the airways that branch off from the trachea into the lungs. The larynx specifically contains the vocal cords, making it the structure responsible for voice production.

Correct Answer: B

Rationale: The correct answer is B: To secrete digestive enzymes. The pancreas secretes enzymes such as amylase, lipase, and protease that aid in breaking down carbohydrates, fats, and proteins in the small intestine. This process is crucial for proper digestion and absorption of nutrients. Choice A is incorrect because the pancreas does not secrete bile, which is produced by the liver. Choice C is incorrect because the absorption of nutrients primarily occurs in the small intestine, not the pancreas. Choice D is incorrect as waste transportation is mainly handled by the intestines and kidneys, not the pancreas.

Correct Answer: D

Rationale: The correct answer is D: Takes shape of container. Liquids do not have a fixed shape but take the shape of the container they are in due to the particles being able to flow and move past each other. Choice A is incorrect as liquids have moderate atomic attraction, not high. Choice B is incorrect as liquids have a fixed volume but not a fixed shape. Choice C is incorrect as liquids can have varying pressures depending on the conditions.

Correct Answer: D

Rationale: The correct answer is D, the cerebrum. The cerebrum is the largest part of the brain and is responsible for higher brain functions such as thought, reasoning, memory, and voluntary actions. It consists of the cerebral cortex, which plays a crucial role in processing sensory information and controlling motor functions. The amygdala (A) is involved in emotions and memory, the brain stem (B) controls basic life functions like breathing and heart rate, and the cerebellum (C) coordinates movement and balance. Therefore, the cerebrum is the correct choice for higher brain functions.
