ATI TEAS Science Questions

1. What type of muscle is found in the walls of hollow organs like the intestines?

Correct answer: B

Rationale: Smooth muscle is the correct type of muscle found in the walls of hollow organs like the intestines. It is responsible for movements such as peristalsis, aiding in the movement of food and other materials through the digestive system. Cardiac muscle (Choice A) is found in the heart and is responsible for the heart's contractions, not in hollow organs like the intestines. Skeletal muscle (Choice C) is attached to bones and responsible for voluntary movements, not in hollow organ walls. Voluntary muscle (Choice D) is another term for skeletal muscle, which is under conscious control, unlike smooth muscle in hollow organ walls.

2. Through what tubes does urine travel from the kidneys to the bladder?

Correct answer: B

Rationale: The correct answer is 'Ureters.' The ureters are the tubes that transport urine from the kidneys to the bladder. The urethra, not a choice in this question, is the tube responsible for carrying urine from the bladder out of the body. Renal arteries and veins are blood vessels that respectively supply and drain the kidneys, not involved in the transport of urine to the bladder.

3. What energy transformation occurs when a guitar string vibrates to produce sound?

Correct answer: D

Rationale: The correct answer is D. When a guitar string vibrates to produce sound, the energy transformation that occurs is from potential energy (stored energy in the string when it is stretched) to kinetic energy (energy of motion as the string vibrates back and forth). As the string vibrates, its kinetic energy is transferred to the surrounding air molecules, producing sound energy. Choices A, B, and C are incorrect. Choice A, mechanical energy to thermal energy, does not align with the energy transformation involved in producing sound from a vibrating guitar string. Choice B, kinetic energy to potential energy, is the opposite of what happens when a guitar string vibrates. Choice C, electrical energy to sound energy, is not relevant to the energy conversion process in this scenario.

4. Which of the following best describes a plane that divides the body into upper and lower portions?

Correct answer: B

Rationale: The correct answer is B: Transverse. A transverse plane, also known as a horizontal plane, divides the body into upper and lower portions. This plane is perpendicular to the long axis of the body. Coronal planes divide the body into anterior and posterior portions. Oblique planes pass through the body at an angle, neither strictly horizontal nor vertical. The median plane passes longitudinally through the body, dividing it into equal left and right halves.

5. Histamine, released during an allergic reaction, causes symptoms like:

Correct answer: B

Rationale: Histamine is a chemical released by the immune system during an allergic reaction. It is responsible for causing symptoms such as a runny nose, itchiness, sneezing, and watery eyes. These symptoms are commonly seen in allergies like hay fever. Fever and fatigue (option A) are not typically caused by histamine release during an allergic reaction. Muscle aches and joint pain (option C) are not common symptoms of histamine release in allergic reactions. Cough and shortness of breath (option D) are more commonly associated with asthma or respiratory allergies rather than histamine release.
