Answer 1

1. Option A is correct.
When carrying a microscope to and from your bench, both hands should be used (One on the arm and the other under the base)

2. TRUE
Primary containment is protecting the immediate surroundings and personnel in a laboratory against infectious agents.

3. Option A is correct.
The ocular lens is located at the top of the instrument and consists of two internal lenses that have a magnification power of 10X

4. Option B is correct.
Bright field microscope allows light rays to pass directly to the eye without being deflected by an intervening opaque plate in the condenser.

5. Option A is correct.
The condenser collects and directs the light from the lamp to the slide being examined.

6. Option A is correct.
The diaphragm regulates the amount of light that reaches the specimen.

7. Option A is correct.
The stage is a horizontal platform that supports the microscope slide.
