ATI TEAS 7 Version 1 Science Questions
Question 1 of 5
Which of the following properties does soap, an emulsifier, have that make it useful for washing dirt off one's hands with water?
Correct Answer: A
Rationale: Soap acts as an emulsifier due to its dual polar (hydrophilic) and nonpolar (hydrophobic) nature, allowing it to effectively bond oil and water, making option A the correct choic

Question 2 of 5
Which of the following organs is covered by the pleura, a connective tissue sheath?
Correct Answer: B
Rationale: The pleura is a protective membrane that covers the lungs. It consists of two layers: the visceral pleura (inner layer) and the parietal pleura (outer layer). The pleural space between these layers contains a small amount of fluid that helps reduce friction during breathing movements. The spleen, heart, and liver are not covered by the pleura. Therefore, the correct answer is the lungs.
Question 3 of 5
What process causes most of the carbon dioxide from the blood to move into alveoli?
Correct Answer: B
Rationale: The correct answer is B: Diffusion down a concentration gradient. In the alveoli, there is a higher concentration of carbon dioxide in the blood compared to the air, leading to the movement of carbon dioxide from the blood into the alveoli through diffusion. This natural movement occurs due to the concentration gradient, ensuring the elimination of carbon dioxide during respiration. Active transport, a process requiring energy, is not involved in this movement. Passive transport using carrier proteins is not the primary mechanism for carbon dioxide movement in the lungs. Conversion to carbon monoxide is incorrect as it does not explain the physiological process of carbon dioxide exchange in the alveoli.

Question 5 of 5
Which of the following allows the skull to rotate on the neck?
Correct Answer: C
Rationale: The atlas is the first cervical vertebra that supports the skull and allows it to rotate on the neck. The vertebral foramen is an opening in the vertebra for the spinal cord, and the spinous process is a bony projection, not involved in rotation.
