ATI TEAS Science Questions

1. What term describes the front of the body, for example, the kneecap?

Correct answer: B

Rationale: The correct answer is 'B: Anterior.' In anatomy, 'anterior' refers to the front of the body, like the kneecap. On the other hand, 'posterior' describes the back of the body. Choices 'C: Superior' and 'D: Inferior' relate to structures being above or below a reference point, respectively, and are not used to describe the front or back of the body. Therefore, 'Anterior' is the most appropriate term given the context provided in the question.

2. How does the amplitude of a wave relate to its intensity or loudness?

Correct answer: B

Rationale: The amplitude of a wave is directly related to its intensity or loudness. In general, the larger the amplitude of a wave, the greater its intensity or loudness. This relationship is due to the fact that the amplitude of a wave represents the maximum displacement of particles in the medium from their rest position. The greater the displacement, the more energy the wave carries, leading to higher intensity or louder sound. Choice A is incorrect because the relationship between amplitude and intensity is direct, not inverse. Choice C is incorrect as there is a clear relationship between amplitude and intensity. Choice D is incorrect as amplitude primarily affects intensity or loudness, not frequency.

3. Which factor do colligative properties of solutions depend on?

Correct answer: D

Rationale: Colligative properties of solutions depend on the number of solute particles in solution. These properties, such as boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure, are proportional to the number of solute particles present in the solution. The chemical identity of the solute or the concentration of the solvent does not influence colligative properties, making choices A and C incorrect. Therefore, the correct answer is D, the number of solute particles in solution.

4. What is a characteristic feature of a convex lens?

Correct answer: A

Rationale: A convex lens is characterized by its ability to converge light rays. The convex lens is thicker in the middle and thinner at the edges, causing light rays passing through it to converge or come together at a focal point on the opposite side of the lens. This convergence of light rays is what distinguishes convex lenses. Choice B is incorrect as convex lenses do not diverge light rays. Choice C is incorrect as convex lenses do not focus sound waves but rather light waves. Choice D is incorrect as convex lenses can create both real and virtual images, not just virtual images.

5. What happens when an atom loses an electron?

Correct answer: B

Rationale: When an atom loses an electron, it gains a positive charge and becomes an ion. This occurs because the number of protons in the atom exceeds the number of electrons, leading to a positive charge. Therefore, the atom undergoes a transformation into an ion by losing an electron. Choice A is incorrect because losing an electron does not result in the formation of a molecule, as molecules are made up of bonded atoms. Choice C is incorrect because losing an electron does not change the fundamental identity of the atom; it only changes its charge. Choice D is incorrect because losing an electron causes the atom to become positively charged, altering its neutrality.
