1. Subtract 32 divided by 8\9.

• A. 36
• B. 32
• C. 40
• D. 44

Correct answer: A

Rationale: 32 ÷ (8\9) is the same as 32 × (9\8) = 36.

2. The procedure to focus an image using a compound microscope involves

• A. Adjusting the coarse adjustment each time a new magnification is selected
• B. Adjusting the fine adjustment each time a new magnification is selected
• C. Adjusting the stage each time a new magnification is selected
• D. All of the above

Correct answer: B

Rationale: When using a compound microscope, it is essential to adjust the fine adjustment knob each time you switch to a new magnification level. The fine adjustment knob allows for precise focusing on the specimen at different magnifications, ensuring a clear and sharp image. The coarse adjustment knob is typically used only at the lower magnification settings to bring the image into view roughly. Adjusting the stage may be necessary based on the size and thickness of the specimen, but it does not need to be done every time a new magnification is selected. Therefore, option B is the correct choice as it focuses on the key aspect of precise focusing during magnification changes.

3. What is the meaning of the word moderation as used in the second paragraph?

• A. Adequate amounts
• B. Intervals of time
• C. Excess
• D. Variation

Correct answer: A

Rationale: In this context, moderation means consuming adequate amounts of unsaturated fats. The passage highlights that unsaturated fats like olive oil and omega-3 fatty acids are beneficial when consumed in appropriate quantities. Choice B, intervals of time, is incorrect as it does not relate to the consumption of fats. Choice C, excess, is incorrect because moderation implies avoiding excess consumption. Choice D, variation, is unrelated to the context of consuming fats in appropriate amounts.

4. All of the following are mentioned in the passage as potential risks from inadequate sleep EXCEPT ___________.

• A. Cancer
• B. Obesity
• C. Diabetes
• D. Depression

Correct answer: A

Rationale: Cancer is not mentioned as a risk associated with inadequate sleep in the passage.

5. What helps the cell maintain its shape and allows it to adapt?

• A. Microfilaments
• B. Cytoplasm
• C. Cytoskeleton
• D. Centrioles

Correct answer: C

Rationale: The cytoskeleton is the correct answer. It provides structural support to the cell, helps maintain its shape, and enables it to adapt to different environments. Microfilaments are part of the cytoskeleton, but they alone do not encompass the entire cytoskeleton's functions. Cytoplasm is the fluid inside the cell where organelles are suspended and is not directly responsible for maintaining cell shape. Centrioles are involved in cell division and do not primarily contribute to maintaining the cell's shape and adaptation.
