TEAS 7 Science Practice Test Questions

Question 1 of 5

Which of the following lobes in the cerebral cortex is primarily responsible for processing and integrating sensory information received from the rest of the body?

Correct Answer: C

Rationale: The correct answer is C: parietal lobe. The parietal lobe is primarily responsible for processing and integrating sensory information received from the rest of the body. It plays a key role in processing touch, pressure, temperature, and pain sensations. Additionally, the parietal lobe is involved in spatial perception, attention, and body awareness. Frontal lobe (A) is responsible for higher cognitive functions such as decision-making and problem-solving. Occipital lobe (B) is primarily responsible for processing visual information. Temporal lobe (D) is involved in processing auditory information and memory functions. Therefore, the parietal lobe is the most appropriate choice for processing and integrating sensory information.

Question 2 of 5

What is the primary function of the pyloric sphincter?

Correct Answer: A

Rationale: The primary function of the pyloric sphincter is to regulate the movement of food material from the stomach to the duodenum. This is crucial for proper digestion as it controls the release of partially digested food into the small intestine for further processing. Choices B and D are incorrect because the pyloric sphincter does not neutralize stomach acid or begin the process of chemical digestion; those functions are carried out by other parts of the digestive system. Choice C is incorrect as preventing digested food materials and stomach acid from entering the esophagus is the primary role of the lower esophageal sphincter, not the pyloric sphincter.

Question 3 of 5

Which of the following correctly describes a strong acid?

Correct Answer: A

Rationale: Correct Answer: A - A strong acid completely ionizes in water. Rationale: 1. Strong acids fully dissociate into ions in water, leading to a high concentration of H+ ions. 2. This complete ionization results in a low pH. 3. Strong acids do not reversibly donate more than one proton or contain metal atoms. 4. Strong acids can decompose under certain conditions, so choice D is incorrect.

Question 4 of 5

Which of the following describes a situation in which research results are consistent with every subsequent experiment, but the test used in the experiment does not measure what it claims to measure?

Correct Answer: A

Rationale: The correct answer is A because this situation indicates that the results are consistent (reliable) across experiments, but the test used does not measure what it claims to measure (not valid). Reliability refers to consistency in results, while validity refers to accuracy in measuring what it intends to measure. Therefore, in this scenario, the results can be consistently replicated (reliable) even though the test does not actually measure the intended concept (not valid). Summary: A: The results are consistent (reliable) but the test is not measuring what it claims to measure (not valid). B: This choice does not fit the scenario described in the question. C: This choice indicates both reliability and validity are lacking, which does not align with the scenario. D: This choice implies that both reliability and validity are present, which contradicts the situation described.

Question 5 of 5

Which of the following are the blood vessels that transport blood away from the heart?

Correct Answer: A

Rationale: The correct answer is A: arteries. Arteries are blood vessels that carry oxygen-rich blood away from the heart to the rest of the body. They have thick, muscular walls to withstand the high pressure of blood pumped by the heart. Capillaries are tiny blood vessels where exchange of nutrients and waste occurs. Venules are small veins that collect blood from capillaries. Veins transport blood back to the heart and are characterized by thin walls and valves to prevent backflow.
