ATI TEAS Science Test Questions
Question 1 of 5
Which of the following areas has the least amount of sweat glands?
Correct Answer: B
Rationale: The correct answer is B - Palms. The palms have the least amount of sweat glands compared to the other options listed. The back, axilla (armpits), and forehead are all areas with a higher concentration of sweat glands in the body. The palms have fewer sweat glands to minimize water loss and maintain a better grip for activities requiring precise and controlled movement. The back, axilla, and forehead have more sweat glands to assist in thermoregulation and cooling of the body, while the palms have fewer sweat glands for functional reasons related to grip and dexterity.
Question 2 of 5
When a certain plant is introduced into an area, and the population of a certain insect species declines, what can be concluded from this?
Correct Answer: D
Rationale: The given scenario presents multiple possible explanations for the decline in the insect population with the introduction of a particular plant. It could be due to the plant being toxic to the insect (Option A), competing with and driving out plants that the insect feeds on (Option B), or the decline could be coincidental with the plant introduction as the insect population was already decreasing (Option C). Without further investigation and evidence, it is not possible to definitively determine which explanation is correct. Therefore, all of these possibilities may be true, and thorough investigation is necessary to reach a conclusive conclusion.
Question 3 of 5
Which of the following items is NOT a primary function of a healthy immune system?
Correct Answer: D
Rationale: The correct answer is D. The primary functions of a healthy immune system do not involve creating infections. A healthy immune system helps the body avoid infections by providing defense mechanisms, detects infections by recognizing harmful pathogens, and eliminates infections by attacking and clearing out pathogens. Creating infections goes against the protective role of the immune system and is not a function it performs. Therefore, choices A, B, and C are correct functions of a healthy immune system, while choice D is incorrect.
Question 4 of 5
Which of the following organs belongs to the digestive system?
Correct Answer: D
Rationale: The correct answer is D: Stomach. The stomach is an organ of the digestive system. Its main function is to break down and digest food, allowing the nutrients to be absorbed into the body. The stomach secretes digestive enzymes and acids to help in the digestion process. Choices A, B, and C are incorrect as the spine, lungs, and brain are not part of the digestive system. The spine is part of the skeletal system, the lungs belong to the respiratory system, and the brain is part of the nervous system.
Question 5 of 5
Which of the following terms means toward the front of the body?
Correct Answer: B
Rationale: The correct answer is B: Anterior. The term 'anterior' specifically refers to the front of the body. In anatomical terms, anterior is the opposite of posterior, which means toward the back of the body. Superior and inferior, choices A and C, respectively, refer to top and bottom directions, not front and back. Therefore, 'Anterior' is the most appropriate term for describing a position toward the front of the body.
