TEAS Practice Test Science

1. Which structure of the endocrine system is responsible for maturing T cells?

Correct answer: C

Rationale: The thymus is the primary gland responsible for the maturation of T cells in the immune system. T cells are a type of white blood cell involved in the immune response. The hypothalamus is primarily involved in hormone regulation and maintaining homeostasis. The pineal gland is responsible for secreting melatonin and regulating the sleep-wake cycle. The thyroid gland plays a key role in metabolism regulation through the production of thyroid hormones. Therefore, the correct answer is the thymus because it is specifically associated with the maturation of T cells, making it essential for proper immune function.

2. A scientist wants to conduct quantitative research. Which method should they use?

Correct answer: B

Rationale: In quantitative research, numerical data is collected and analyzed. Choice B, tracking the dosage of a drug and its blood levels in the patient, involves collecting quantitative data, making it the correct method. Choices A, C, and D involve qualitative data such as narratives, physical observations, and journal notes, which do not align with the quantitative research method.

3. Which of the following is responsible for carrying oxygenated blood from the heart to the body?

Correct answer: B

Rationale: The correct answer is B: Artery. Arteries carry oxygenated blood away from the heart to the body. Veins carry deoxygenated blood back to the heart, capillaries are tiny blood vessels where gas exchange occurs, and lymphatic vessels are part of the lymphatic system, which is responsible for draining excess fluid from tissues and transporting white blood cells.

4. Which of the following lobes of the brain is primarily responsible for vision?

Correct answer: B

Rationale: The occipital lobe is primarily responsible for processing visual information. It contains the primary visual cortex, which plays a key role in interpreting visual stimuli. The frontal lobe is more associated with functions such as decision-making and problem-solving, making choice A incorrect. The parietal lobe is involved in processing sensory information but not specifically vision, making choice C incorrect. The temporal lobe is responsible for functions like memory and auditory processing, so choice D is also incorrect.

5. What type of immunity does a vaccine provide? Choose only ONE best answer.

Correct answer: D

Rationale: The correct answer is D: Artificially acquired active immunity. Vaccines work by stimulating the immune system to produce an active response, leading to the development of immunity against specific pathogens. Choice A, naturally acquired passive immunity, is incorrect as it refers to the temporary immunity passed from mother to child, not through vaccines. Choice B, artificially acquired passive immunity, is also incorrect because passive immunity involves the transfer of pre-formed antibodies, not the stimulation of the immune system by vaccines. Choice C, naturally acquired active immunity, is incorrect since it is acquired through natural exposure to pathogens, not through vaccines.
