TEAS version 7 quizlet science

1. Which of the following is NOT a type of epithelium?

Correct answer: D

Rationale: The correct answer is D, Pseudostratified columnar. Pseudostratified columnar epithelium is not a type of epithelium. It is a specialized form of simple columnar epithelium. Stratified squamous, simple cuboidal, and stratified columnar are all types of epithelial tissues found in the human body. Stratified squamous epithelium is found in the skin, mouth, and esophagus; simple cuboidal epithelium lines kidney tubules and glands; stratified columnar epithelium is present in parts of the respiratory tract and male urethra.

2. Which of the following terms refers to the abnormal sound heard during a stethoscope examination, potentially indicating a heart valve issue?

Correct answer: C

Rationale: A heart murmur is an abnormal sound heard during a stethoscope examination of the heart. It can indicate issues with the heart valves, such as stenosis or regurgitation. Tachycardia refers to a fast heart rate, bradycardia refers to a slow heart rate, and arrhythmia refers to an irregular heart rhythm. Therefore, the correct answer is 'Heart murmur,' as it specifically relates to the abnormal sound heard during a stethoscope examination that may signal a heart valve issue.

3. The process by which two or more species reciprocally influence each other's evolution through selection pressures exerted on one another is called:

Correct answer: C

Rationale: A) Convergent evolution refers to the process by which unrelated species evolve similar traits due to similar environmental pressures. This does not involve reciprocal influence between species. B) Divergent evolution refers to the process by which two or more related species become more dissimilar over time due to different selection pressures. This also does not involve reciprocal influence between species. C) Coevolution is the process by which two or more species reciprocally influence each other's evolution through selection pressures exerted on one another. This can lead to a close ecological relationship between the species, such as in predator-prey interactions or mutualistic relationships. D) This option is a duplicate of option C.

4. What phenomenon explains the bending of light as it passes around an obstacle or through an aperture?

Correct answer: C

Rationale: Diffraction is the phenomenon that explains the bending of light as it passes around an obstacle or through an aperture. When light encounters an obstacle or passes through an aperture, it diffracts, causing it to bend around the edges. Refraction, on the other hand, occurs when light passes from one medium to another, causing it to change direction. Reflection involves the bouncing back of light rays from a surface, and dispersion is the separation of light into its different colors. Therefore, the correct answer is C, as diffraction specifically addresses the bending of light as it interacts with obstacles or apertures, unlike the other choices that describe different optical phenomena.

5. Which of the following salt solutions is most likely to conduct electricity well?

Correct answer: B

Rationale: A concentrated solution of a strong electrolyte is most likely to conduct electricity well. Strong electrolytes completely dissociate into ions in solution, allowing for the flow of electric current. This high concentration of ions in the solution enhances its conductivity, making it a better conductor compared to other options. A saturated solution, although containing dissolved ions, may not have a high enough concentration to conduct electricity effectively. A dilute solution of a weak acid is a poor conductor as weak acids only partially dissociate into ions. A mixture of a neutral compound and water does not contain free ions necessary for conducting electricity.
