Explanation:

1.

Magnification on a light - microscope is calculated by multiplying the magnification of the ocular lens (usually 10x) by the magnification of the objective lens (e.g., 4x, 10x, 40x, 100x).

To focus a microscope using the high - power lens, first focus on low power to center the specimen. Then, switch to high power and use the fine - adjustment knob gently. Safety issues include keeping hands away from the objective lens to avoid damage and wearing protective eyewear if needed.

Sketch should include details of what was observed in the lab, such as cell shapes, structures, or any unique features.

Answer:

Multiply the magnification of the ocular lens by the magnification of the objective lens.
