1. Which property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. What happens when an atom loses an electron?

• A. It becomes a molecule.
• B. It gains a positive charge and becomes an ion.
• C. It changes its element identity.
• D. Nothing happens, it remains neutral.

Correct answer: B

Rationale: It gains a positive charge and becomes an ion. Losing an electron disrupts the charge balance, leaving the atom with more protons than electrons and a positive charge.

3. Identify the indirect object in the following sentence: "He gave his mother a bouquet of flowers."

• A. mother
• B. bouquet
• C. flowers
• D. gave

Correct answer: A

Rationale: The indirect object tells who or what benefits from the action of the verb.

4. What is the stage of mitosis during which the nuclear envelope reforms?

• A. Prophase
• B. Metaphase
• C. Telophase
• D. Cytokinesis

Correct answer: C

Rationale: Rationale: - Prophase is the stage of mitosis where the nuclear envelope breaks down, allowing the chromosomes to condense and become visible. - Metaphase is the stage where the chromosomes line up along the metaphase plate in the middle of the cell. - Telophase is the stage where the nuclear envelope reforms around the separated sister chromatids at opposite poles of the cell. - Cytokinesis is the final stage of cell division where the cytoplasm divides to form two daughter cells, but it is not directly related to the reformation of the nuclear envelope.

5. Which of the following is NOT a common symptom of lactose intolerance?

• A. Gas
• B. Bloating
• C. Diarrhea
• D. Nausea

Correct answer: D

Rationale: Rationale: A) Gas: Gas is a common symptom of lactose intolerance. When lactose is not properly digested, it can ferment in the colon, leading to the production of gas. B) Bloating: Bloating is another common symptom of lactose intolerance. The buildup of gas in the digestive system can cause bloating and discomfort. C) Diarrhea: Diarrhea is a common symptom of lactose intolerance. When lactose is not broken down in the small intestine, it can draw excess water into the colon, resulting in diarrhea. D) Nausea: Nausea is not a common symptom of lactose intolerance. While some individuals may experience mild stomach discomfort or cramps, nausea is not typically associated with lactose intolerance.

6. Stretch marks occur when

• A. The dermis layer becomes inflamed
• B. The dermis layer becomes inflamed
• C. The dermis layer tears due to rapid stretching
• D. Sebaceous glands become clogged

Correct answer: C

Rationale: Stretch marks occur when the dermis layer tears due to rapid stretching. During periods of rapid growth or weight gain, the skin may stretch beyond its capacity, causing the dermis layer to tear and resulting in the formation of stretch marks. Inflammation or clogged sebaceous glands do not directly cause stretch marks, making options A, B, and D incorrect. It is important to understand the physiological process behind stretch marks to identify the correct answer.
