Actual ATI TEAS 7 Test Questions Set 2

Science

Question 1.

In order to determine the effects of energy drinks on women's running speed, researchers gave 300 women an energy drink and then recorded the time it took each of them to run 2 miles. After collecting the results, researchers concluded that energy drinks increase the speed of running in women. Which of the following further tests would best help to support this conclusion? Repeat the same experiment, using 300 men.

  • A: Repeat the experiment, giving half of the women water and the other half the energy drink.
  • B: Repeat the experiment having half of the women run 2 miles and the other half run 5 miles.
  • C: Repeat the experiment, giving the women two different energy drinks.
  • D: Repeat the experiment, giving the women two different energy drinks.
  • Correct Answer: B

  • Rationale: To further support the conclusion that energy drinks increase running speed in women, the best approach would be to repeat the experiment with men. By having half of the men run 2 miles (similar to the original experiment with women) and the other half run a longer distance such as 5 miles, researchers can determine if the effects of energy drinks on running speed are consistent across different distances. This would provide a more comprehensive understanding of the impact of energy drinks on both genders and different running distances.

Question 2:

Which of the following respiratory structures is affected by a disease that disrupts gas exchange, such as emphysema?

  • A: Trachea
  • B: Alveoli
  • C: Secondary bronchi
  • D: Primary bronchi
  • Correct Answer: B

  • Rationale: Emphysema is a condition that primarily affects the alveoli in the lungs. Alveoli are tiny air sacs where the exchange of oxygen and carbon dioxide occurs. In emphysema, the walls of these air sacs break down, reducing the surface area available for gas exchange. This leads to impaired respiratory function, making it harder for oxygen to enter the bloodstream and for carbon dioxide to be removed. Therefore, the correct answer is the alveoli (Choice B).

Question 3:

The vermiform appendix extends from which region of the intestine known as which of the following?

  • A: Ischium
  • B: Cecum
  • C: Rectum
  • D: Jejunum
  • Correct Answer: B

  • Rationale: The correct answer is B, Cecum. The vermiform appendix is a small, tube-like structure that extends from the cecum, which is the beginning of the large intestine. The cecum is located in the lower right quadrant of the abdomen. It is important to understand the anatomical relationships between different parts of the intestine to identify the origin of the appendix.

Question 4:

When a volcano erupts, its actions are similar to which of the following events?

  • A: A tree root pushing up through the pavement
  • B: A can of soda fizzing when it's opened
  • C: A building burning to the ground
  • D: A flood eroding the banks of a stream
  • Correct Answer: B

  • Rationale: When a volcano erupts, it releases built-up pressure, gases, and magma explosively, similar to the fizzing action of a can of soda when opened. Just like how gas in a soda can cause pressure and fizz when released, the pressure within a volcano causes an explosive release of material during an eruption. This makes choice B the most analogous event to a volcanic eruption among the options provided. The other options do not capture the sudden, forceful, and explosive nature of a volcanic eruption.

Question 5:

Which one of the following structures drains oxygen-depleted blood from the kidneys?

  • A: Ureter
  • B: Renal artery
  • C: Urethra
  • D: Renal vein
  • Correct Answer: D

  • Rationale: The correct answer is D, Renal vein. The renal vein is responsible for draining oxygen-depleted blood from the kidneys back to the heart for reoxygenation. The ureter carries urine from the kidneys to the bladder, the renal artery supplies oxygenated blood to the kidneys, and the urethra is the tube that carries urine from the bladder out of the body. Therefore, in the context of blood drainage from the kidneys, the renal vein is the correct choice.
