1. In which direction do the particles of the medium move in a transverse wave?

• A. Perpendicular to the direction of wave travel
• B. Parallel to the direction of wave travel
• C. In a circular motion
• D. Opposite to the direction of wave travel

Correct answer: a

Rationale: In a transverse wave, particle displacement occurs perpendicular to the direction of wave travel.

2. What is the meaning of the idiom "to cross that bridge when we come to it"?

• A. To deal with a problem immediately
• B. To plan for the future in detail
• C. To worry about potential problems prematurely
• D. To avoid difficult situations

Correct answer: C

Rationale: The idiom suggests dealing with challenges as they arise, not before.

3. What is the best way to revise the sentence: "Her eyes glistened with tears in the moonlight"?

• A. Her eyes glistened in the moonlight, with tears.
• B. Tears glistened in her eyes with moonlight.
• C. Her eyes, in the moonlight, glistened with tears.
• D. Tears made her eyes glisten in the moonlight.

Correct answer: C

Rationale: Option C rearranges the elements for smoother flow and emphasis on the tears.

4. Which test is commonly used to assess kidney function?

• A. Complete blood count (CBC)
• B. Blood sugar test
• C. Urinalysis
• D. Creatinine clearance test

Correct answer: D

Rationale: The correct answer is D: Creatinine clearance test. This test is commonly used to assess kidney function by measuring how well the kidneys are filtering waste products like creatinine from the blood. Creatinine is a waste product produced by muscles and is normally filtered out by the kidneys. A high level of creatinine in the blood can indicate reduced kidney function. Options A, B, and C are not specifically used to assess kidney function. A complete blood count (CBC) measures different components of the blood like red blood cells, white blood cells, and platelets. A blood sugar test is used to measure glucose levels in the blood. Urinalysis is a test that analyzes the urine for various substances like proteins, glucose, and blood cells, but it is not the primary test for assessing kidney function.

5. Two coherent light waves with a slight phase difference interfere. What determines the resulting intensity of the combined wave?

• A. The individual intensities of the waves
• B. The wavelength of the waves
• C. The distance between the waves
• D. The color of the waves

Correct answer: A

Rationale: The intensity of the resulting wave depends on the individual intensities and the phase difference between the interfering waves. Constructive interference leads to higher intensity, while destructive interference leads to lower intensity.

6. Which of the following phases of mitosis is characterized by the separation of sister chromatids and their movement to opposite poles?

• A. Metaphase
• B. Anaphase
• C. Anaphase
• D. Cytokinesis

Correct answer: B

Rationale: Rationale: During anaphase of mitosis, the sister chromatids, which are duplicated copies of a chromosome, separate and move towards opposite poles of the cell. This movement is facilitated by the shortening of microtubules attached to the chromatids. As a result, each pole of the cell receives a complete set of chromosomes, ensuring that the daughter cells produced after cell division will have the correct number of chromosomes. Metaphase is characterized by the alignment of chromosomes at the cell's equator, not their separation. Telophase is the phase following anaphase, where the separated chromatids reach the opposite poles and nuclear envelopes start to form around them. Cytokinesis is the final stage of cell division, where the cytoplasm is divided to form two separate daughter cells.
